[00:13:33] <GregorR> Bleh, haven't figured out how to get a working version of 2.6.28-omap1 with the new DSS2 stuff :(
[00:22:01] <emeb> Crofton|work - sorry for delay. The url I'm using for setting up OE is http://elinux.org/BeagleBoardAndOpenEmbeddedGit
[00:22:45] <emeb> bitbake continues past that error and I'm deep into it now. No telling if the error is ultimately fatal.
[00:27:45] * watarat (i=7cab5649@gateway/web/ajax/mibbit.com/x-67698d36ccb3711d) Quit ("http://www.mibbit.com ajax IRC Client")
[00:34:14] <GregorR> tomba: You mentioned yesterday that it's possible to get NTSC going even with the older DSS2, it just wasn't switchable. As it turns out I need 2.6.28 for USB (until that's fixed in the latest), and the latest DSS2 won't compile under 2.6.28; how does one switch the older DSS2 to NTSC?
[00:42:51] * like2wise (n=chatzill@82-171-51-231.ip.telfort.nl) Quit ("ChatZilla 0.9.84 [Firefox 3.0.8/2009032711]")

[00:47:29] <ds2> downix: do publish a generic CF interface design
[00:47:34] * __alanc__ (n=a-campbe@nat/ti/x-a559f8387898e390) has joined #beagle
[00:47:47] <downix> ds2: ??
[00:48:29] * Batko_Marto (n=Batko_Ma@CPE001346f996d2-CM001e6b1a8d1e.cpe.net.cable.rogers.com) has joined #beagle
[00:49:27] <mru> isn't CF more or less IDE?
[00:51:44] <downix> pretty much
[00:51:58] <downix> It's ideal for a few tasks, such as I'm planning on
[00:52:43] * Yuvi (n=yuvi@resnet-241-44.resnet.umbc.edu) Quit (Read error: 60 (Operation timed out))
[00:53:17] * Yuvi (n=yuvi@resnet-241-44.resnet.umbc.edu) has joined #beagle
[00:54:13] <mru> usb-ide converters are everywhere
[00:54:27] <ds2> downix: a generic CF interface would allow people to add all sorts of stuff
[00:54:28] <mru> and ide-cf adapters look simple
[00:54:36] <downix> right, but finding one with the power and profile needs is more difficult
[00:54:48] <downix> I am running on an ever thinner wattage needs
[00:54:55] <downix> ds2: you got it. 8)
[00:55:15] <ds2> CF is nice and avoids issues that SDIO has but getting it to work on the beagle can be "interesting"
[00:55:24] <mru> if you're planning on using non-storage cf devices it might get trickier
[00:55:36] <downix> hence why I'm being very cautious
[00:56:04] <ds2> if the beagle brought out the NOR interface, it would be pretty easy
[00:56:09] <ds2> CF is basically just ISA
[00:56:16] <downix> NOR?
[00:57:01] <downix> unaware beagle had that option
[00:57:10] <ds2> I did say 'if'
[00:57:21] <ds2> the OMAP3 supports it but the pins are not brought out
[00:57:31] <ds2> EVM
[00:57:37] <ds2> Zoom/etc can use it
[00:57:43] <mru> could you use a usb-pcmcia adaptor?
[00:58:09] <mru> hooking a cf card to that should be only a matter of wires

[02:06:54] <djlewis> still no webcam capture and my mplayer gui borke the other day on my new amngstrom
[02:18:25] <GregorR> Dern, this problem is so weird ... it detects the hub I have plugged into EHCI, but then when it mounts the root, it "detects" a disconnection ...

[02:57:57] <GregorR> In spite of the fact that all I've done was take the 2.6.28-omap1 tag and apply the patches from Angstrom, my self-compiled kernel doesn't boot, which probably doesn't help anything either >_<

[04:05:47] <GregorR> Well, I've managed to produce another kernel that's not capable of supporting USB at all X_X
[04:05:49] <GregorR> That's useful.
[04:10:29] <djlewis> you have been hard at it.
[04:10:59] <ds2> the EHCI port enumerated the first time... wonder what changed that is causing you the issues
[04:14:20] <GregorR> I'm trying (for no particular reason) with EHCI as a module instead ... that way it will load /after/ the root is mounted. I don't know why that would make a difference.

[04:41:07] <djlewis> and I nave only accomplished a black frame with some pixel noise.
[04:54:21] <GregorR> Sweet.
[04:54:29] <GregorR> So both of us have clearly accomplished everything we set out to :P
[04:54:57] * russ (i=foobar@ip70-176-253-20.ph.ph.cox.net) has joined #beagle
[04:56:28] <djlewis> yep, thats the way I see it too :s
[05:08:32] <tomba> GregorR: you need to modify venc.c. the change should be quite obvious, but I can't remember the exact line. in some init function pal config is set as the default one, you just need to change that to ntsc
[05:08:37] * brolin (n=brolin@190.157.13.75) Quit (Client Quit)
[05:13:57] <sakoman_> Hi tomba!
[05:14:27] <sakoman_> I'm just updating my builds with your latest DSS2
[05:15:21] <sakoman_> There are a couple of patches I've been using on my version;
[05:15:25] <sakoman_> http://www.sakoman.net/cgi-bin/gitweb.cgi?p=linux-omap-2.6.git;a=commit;h=f89561e2caa996989f187fdfc28216bb5e172692
[05:15:42] <sakoman_> http://www.sakoman.net/cgi-bin/gitweb.cgi?p=linux-omap-2.6.git;a=commit;h=800569897fde8aa32b65a6f105b6e46f7028d2e4
[05:16:28] <sakoman_> The second is to prepare for upcoming 3.5" and 7.0" LCD panels
[05:17:17] <tomba> hmm looks like my nameserver just broke down. argh. I'll check those later. are they board/display patches, or do they touch dss/omapfb?
[05:17:45] <russ> www.sakoman.net has address 74.41.60.154
[05:17:51] <sakoman_> they just touch the samsung panel driver and the overo board file
[05:18:07] <tomba> russ: thanks =)
[05:18:23] <sakoman_> tomba: both are trivial one liners
[05:18:34] <tomba> why recommended_bpp 16?
[05:18:36] <russ> tomba: in the mean time, /msg ibot nslookup <host>
[05:19:01] <tomba> russ: ohh. the things they come up with...
[05:19:32] <russ> tomba: watch this
[05:19:46] <sakoman_> tomba: otherwise it defaults to 24 bpp, which breaks the sgx stuff on the 3530 varient of overo
[05:19:53] <russ> tomba: I should really ask tim if he can drop ibot in her, he is fun to have around
[05:20:55] <tomba> sakoman_: ah ok. I think you should mark it with a comment, as it's (hopefully) only temporary
[05:21:26] <sakoman_> tomba: heh, you are quite the optimist ;-)
[05:21:38] <tomba> sakoman_: although... perhaps I can leave it out from my tree
[05:22:01] <sakoman_> That would be fine
[05:22:34] <tomba> there's also a problem with the latest dss2 and xvideo, I'll try to sort that out today
[05:22:57] <sakoman_> tomba: was just about to test that
[05:27:53] <russ> hmmm...its too bad that powerdomains seem orthogonal to regulators
[05:28:20] <russ> that would make it fairly easy to know when a regulator that has a powerdomain as a consumer to shut down or suspend
[05:29:03] <sakoman_> tomba: you are correct re: xvideo with latest dss2: "[VO_XV] It seems there is no Xvideo support . . ."
[05:29:25] <tomba> sakoman_: hmm. I didn't get that. I got some setup_plane error
[05:29:42] <sakoman_> this is from mplayer with -vo xv
[05:30:01] <tomba> X should complain when it's starting
[05:30:21] <tomba> although I still starts, but I guess Xv is disabled then
[05:31:27] <sakoman_> tomba: that message is from mplayer, in dmesg I see: omapfb omapfb: setup_plane failed
[05:32:01] <sakoman_> tomab: Let me know if you need any debug info
[05:32:32] <ds2> Hmm
[05:32:43] <tomba> I already where it fails, but I haven't yet studied why it happens. for some reason the phys address of the fb is 0 when setup plane is called
[05:33:28] <sakoman_> ah yes, we were fighting that issue a couple of weeks ago IIRC
[05:36:23] <sakoman_> hmm . . . guess I didn't RC, it was virtual resolution being 0 that caused our last issue
[05:37:55] <tomba> previously I didn't have check for the paddr, but I added it as somehow v4l2 was passing zero and it was a bug. but it seems this fix broke Xv
[05:43:17] <tomba> sometimes this feels quite futile, fb and omapfb APIs are not very clearly defined, and everybody is using them in a different way
[05:45:10] <sakoman_> tomba: it must be quite frustrating! not having a clearly defined interface is a recipe for ongoing pain :-(
[05:45:42] <sakoman_> we all really appreciate the effort you are putting into dss2
[05:46:34] <sakoman_> despite these issues, it is a *vast* improvement over dss1!
[05:48:39] <tomba> nice to hear =). there are still a few bigger things I want to fix before trying to push it to upstream. but perhaps some day...
[05:49:58] <ds2> sakoman_: what are you calling DSS1?
[05:50:25] <sakoman_> ds2: that which is in linux-omap
[05:50:25] <tomba> the omapfb driver in the official kernel
[05:50:46] <ds2> tomba: which official kernel? the TI reference one or the l-o one?
[05:50:58] <tomba> I don't think TI
[05:51:04] <tomba> TI's counts as official =)
[05:51:21] <tomba> so yes, as sakoman said. l-o or Linus' one
[05:51:21] <ds2> it is a few centuries ahead of the L-O for sure
[05:51:53] <tomba> it's also (was at least at some point) an unbelievably ugly hacked together mess
[05:54:09] <tomba> (I may be exaggerating a bit =). but at least their new DSS driver wasn't very good, in my opinnion
[05:54:53] * midtown (i=44bd685e@gateway/web/ajax/mibbit.com/x-d7a139c3a81d4ee4) Quit ("http://www.mibbit.com ajax IRC Client")
[06:01:02] <ds2> more of an understatement
[06:01:44] <ds2> having looked at the code, I can very much appreciate the hardwork that went into it

[06:13:11] <AV500> I think I ran it all through indent 1st

[06:32:56] <GregorR> Well, I've come full circle and am now using a kernel which, by all accounts (and I mean this literally) should work with USB.
[06:33:00] <GregorR> Of course, it doesn't.
[06:33:38] <GregorR> In fact, the only kernel I've found that's worked at all with USB was the one that Angstrom built, even when I compiled what is, as far as I can judge, the exact same kernel, it didn't work.
[06:33:53] <GregorR> And then, I went to sleep :P
[06:37:13] <recalcati> morning

[07:33:05] <ds2> :D
[07:33:11] <tomba> well, not really =)
[07:33:47] <tomba> 1) I want to implement the display devices as linux devices. that's needed for regulator framework, and I think it makes things a bit clearer too. I've started it, but it's a big change
[07:34:15] * mib_68395f (i=40e4c4e8@gateway/web/ajax/mibbit.com/x-36ca063d83b93949) Quit (Client Quit)

[07:35:03] <ds2> isn't it that way already?
[07:35:05] <tomba> 3) I don't remember this one anymore.
[07:35:24] <tomba> not really, it has just this custom omap_display struct
[07:36:05] <ds2> Oh like that
[07:36:36] <ds2> will you also fix it for the remote frame buffer implementations like on the N8x0?
[07:36:46] <tomba> oh, 3) locking & ref counting. this is important for using v4l2 + fb at the same time
[07:37:08] <geckosenator> and the normal ioctls aren't enough I guess
[07:37:11] <geckosenator> to configure all the settings
[07:37:14] <tomba> N800 should "work" already, I have a hacked patch. but I'm not interested in properly implementing it
[07:37:37] <ds2> ah heh
[07:37:40] <geckosenator> some framebuffer drivers have a mmio memory mapped section.. I think you can poke memory there to send commands

[07:39:23] <ds2> geckosenator: I finally have a write up for my thingie
[07:40:02] <geckosenator> cool
[07:40:10] <geckosenator> I'm still thinking about getting a pico projector
[07:40:12] <geckosenator> but the price is high
[07:40:25] <geckosenator> also the power consumption is high
[07:40:38] <geckosenator> I wish I knew how much of it was led though
[07:40:45] <ds2> the Pico is nice
[07:40:56] <geckosenator> you have one?
[07:40:59] <ds2> yes
[07:41:01] <tomba> Stskeeps: sounds cool
[07:41:10] <geckosenator> ds2: would you be able to sell it?

[07:41:37] <ds2> but then ask again in a few months and it may all change :-S
[07:41:50] <geckosenator> hmm
[07:42:02] <geckosenator> I have a few weeks at most to wait around
[07:42:20] <geckosenator> do you know how much power it uses with the led at the lowest setting?
[07:43:16] <ds2> I am not completely sure the LED brightness is adjustable
[07:43:26] <geckosenator> I _have_ to move to the forest by may, or I lose my mind :-P
[07:43:32] <ds2> I suspect it may be but I haven't played with the I2C port given Koen's warning
[07:43:36] <geckosenator> ds2: koen showed me a patch and it is
[07:43:42] <geckosenator> over i2c
[07:44:10] <geckosenator> well how hard is it?
[07:44:11] <ds2> Koen also experienced some side effect behavior when talking to it with i2c
[07:44:14] <geckosenator> the i2c is already wired up
[07:44:36] <geckosenator> I think you just run a program to set the brightness
[07:44:39] <ds2> it isn't so much that it is hard... you can do "stuff" to it over i2c that you really don't want to do
[07:44:48] <geckosenator> hmm
[07:44:54] <geckosenator> well is the picture sharp?
[07:45:16] <geckosenator> since I am going to be sleeping under a tarp, I figure it can act as a dual role of also being my projector screen
[07:45:17] <koen> ds2: in production picos the dangerous stuff has been hidden
[07:45:29] <ds2> koen: thought you wiped out a production unit?
[07:45:37] <koen> tomba: XV indeed works again :)
[07:45:38] <ds2> geckosenator: yes, there is a manual focus
[07:45:48] <koen> ds2: it had an old firmware
[07:46:01] <geckosenator> manual focus is good
[07:46:08] <ds2> Koen: oh...cool.. I been afraid to send i2c commands
[07:46:28] <geckosenator> so you need to upgrade the firmware on the pico?

[07:49:57] <koen> geckosenator: the problem was that they guarded the erase command with a certain sequence of i2c commands

[07:52:03] <geckosenator> oh
[07:52:16] <geckosenator> well I'm glad you figured that out
[07:52:21] <geckosenator> since it would have confused me
[07:52:34] <geckosenator> so.. you just disable probing?
[07:52:40] <geckosenator> or change the sequence?
[07:53:17] <ds2> geckosenator: I have designed my board so it can co-exist with the Pico
[07:53:19] <koen> the fpga thingy doesn't show up anymore on the i2c bus
[07:53:49] <ds2> geckosenator: almost forgot, the URL for the write up is at http://www.hy-research.com/beagle_mid.html
[07:54:09] <koen> so if your pico registers 2 devices on the i2c bus, be affraid
[07:54:37] <ds2> I like working picos, so I will refrain from unneeded I2C experiments :D
[07:55:01] <geckosenator> koen: can it actually destroy the pico?
[07:55:02] <ds2> koen: any luck with pico scanning?
[07:56:46] <koen> geckosenator: not, it just bricks it
[07:56:57] <koen> ds2: haven't allocated time for that yet
[07:57:22] <ds2> koen: me too

[07:59:08] <recalcati> it runs! but normally, with, we have HDCP problem, so it could not work
[08:00:21] <koen> recalcati: if you mail me the patch I can add it to the OE kernel
[08:00:59] <koen> ds2: reprap is on my todo as well, but I need to find good sources for the parts first
[08:01:11] <recalcati> koen: I try
[08:01:13] <ds2> koen: whichpart? extruder or the motion?
[08:01:26] <koen> ds2: and using a beagle to control it instead of the arduino/sanguino would be nice as well (and save $$$)
[08:01:32] <ds2> koen: and are you focusing on the granulated extruded or willing to settle for the filament?
[08:01:47] <koen> ds2: I'd be willing to settle for the filament
[08:02:20] <ds2> koen: what software on the beagle? I would like to see EMC running on it first... in fact EMC/x86 is what I persueing for my control inplace of the arduino + java solution

[08:32:24] <skhimsara> hey..thanks :)
[08:32:29] <koen> raster: what's you plan for support right-angle rotation in evas?

[08:33:48] <AV500> head.rotate(90)
[08:35:19] * koen suspects NEON can do 90, 180, 270 and 360 pretty fast
[08:35:28] <raster> koen: its supported
[08:35:34] <raster> already
[08:35:38] <koen> awesome
[08:35:41] <raster> you dont need neon for it
[08:35:47] <AV500> 360 is the fastest!
[08:35:58] <raster> for < 32bpp u simply scan the soruce data differently
[08:35:59] <koen> then I read the commit comment for the exif rotation support wrong :)
[08:36:13] <raster> it rotates while converting to 8/15/16bpp etc.
[08:36:17] <raster> so you get them both in 1 go
[08:36:39] <raster> for 32bpp its just a memcpy with non-sequential linear access
[08:36:53] <AV500> so no tile in internal mem?
[08:36:55] <raster> there isnt a lot u can do to speed up a rotated blit without totally redoing the memory setup
[08:37:02] <raster> ie tiles
[08:37:08] <AV500> k
[08:37:19] <raster> AV500: normal mem is just that.. normal mem
[08:37:24] <raster> you could treat it as tiles
[08:37:30] <raster> but u'd complicte your access logic
[08:37:44] <raster> so what you make up for more cache coherency on rotates and comp,lex transforms
[08:37:54] <raster> you'd lose on simpler ops with more complex access calcs
[08:38:14] <raster> i actually dont know if it would in the end help or hinder
[08:38:16] * eFfeM (n=nly91006@neo-y1a.ehv.campus.philips.com) has joined #beagle
[08:38:18] <eFfeM> hi
[08:38:25] <raster> i've neer written a sufficient software engine in tiled mode to test
[08:38:37] <AV500> k
[08:38:37] <tomba> VRFB rotation maps the memory a bit differently to make ram access more efficient
[08:38:39] <raster> but... a gut feeling tells me that tiled mem would end up being a zero sum gain
[08:38:43] <raster> (in software)
[08:39:01] <raster> if you have silicon effectively virtualising your tile access... then i can see it being a b ig win
[08:39:03] <raster> big win
[08:39:08] <AV500> if you had a standalone rotate_blit() call, you could just tile this one
[08:39:09] * florian_kc is now known as florian
[08:39:24] <raster> AV500: u'd have to tile both src and dest first
[08:39:34] <raster> tjhen convert from tile to linear
[08:39:40] <raster> in the end i dont see that being a gain :(
[08:39:51] <raster> if u have to convert at either end - any gains u get will bne lost
[08:40:14] <raster> if u can do it without conversion (both src and dest are tiled mem) then there is a gain to be had.
[08:40:24] <AV500> ok, I missthought, my tiles would be just virtual in the cache lines
[08:40:50] <AV500> if there was enouf space for a "square" area in cache
[08:41:06] <AV500> actually 2, one for read and one for write
[08:41:11] <raster> yeah
[08:41:17] <raster> u need to design your tiles to fit in cache
[08:41:28] <raster> as such the best arrangement is to have a tile be 1 cacheline
[08:41:45] <raster> eg if a cacheline is 1024 bytes, 8x8 tiles (@32bpp) are perfect
[08:42:07] <raster> as chances are u will access data withint he tile when rotating or doing complex things like interpolated scaling
[08:42:28] <raster> thus on access to anpy pixel in a tile - u load the whole tile in (ie just prefetch a whole cacheline)
[08:42:31] <florian> good morning
[08:42:32] <AV500> but for scaling you end up with larger and smaller tiles
[08:42:37] <raster> and thereafter your accesses should be hyper-fast
[08:42:50] <raster> well scaling it depends how much
[08:43:00] <raster> as such you go form src whic is tiled @ a tile size
[08:43:03] <raster> and dest - whcih is the same
[08:43:10] <raster> so you produce the same sized tiles either end
[08:43:13] <raster> just tile contents change
[08:43:23] <AV500> yes, but you have inter-tile dependencies unless you do nearest-neon only
[08:43:29] <raster> this is one of the reasons 3d hw can do scales and rottates so fast of textures
[08:43:31] <AV500> no?
[08:43:33] <raster> tiled layout of the tex
[08:43:38] <raster> oih sure
[08:43:47] <raster> not all access are totally wihtin a tile
[08:44:01] <raster> thus in general you probably have at most 4 src tiles when doing any ops
[08:44:13] <raster> (so u can do linear intermp between the edge pixels of a tile)
[08:44:15] <AV500> yeah right, the "filter" just gets more complex

[08:44:28] <raster> yup
[08:44:28] <furan> raster=rasterman?
[08:44:29] <AV500> but in the end only the get_ptr(x,y) needs to be added
[08:44:33] <AV500> furan: yes
[08:44:39] <raster> the problem is simply for every pixle access the "pointer" is no longer
[08:44:49] <raster> (y * bytes_per_line) + x
[08:45:02] <AV500> yes, it is "complex"
[08:45:03] <raster> it now becomes a fairly compl4ex set of indirections (relatively speaking) in the math
[08:45:03] <furan> ltns, you tried to convince me that stardock needed to write a window manager layer for windows long ago
[08:45:12] <raster> doing scalines even u dont do the y * bpl even
[08:45:17] <raster> u do it once at the start of the scanline
[08:45:22] <raster> then just ptr++
[08:45:26] <raster> for output anyway
[08:45:33] <raster> for unscaled iunput its just the same
[08:45:35] <raster> so really simple
[08:45:40] <AV500> well, and the fact that youi have to convert to linear to display that all in the end
[08:45:45] <raster> furan: i did?
[08:45:46] <raster> :)
[08:45:49] <raster> i can't remember!
[08:45:50] <raster> :)
[08:46:01] <raster> AV500: bingo.
[08:46:08] <furan> yeah, think it stemmed from a conversation about litestep
[08:46:11] <raster> in the end.. you end up with having to pump out linear pixels
[08:46:16] <furan> I work on the window manager in windows now :)
[08:46:21] <raster> of course.. that all depends on your drawing complexity
[08:46:40] <raster> if u spend 90% of your time "compositing": the tiled "backbuffer"
[08:46:43] <raster> ie rendering it
[08:46:49] <raster> and only spend 10% of your time copying it to screen
[08:46:57] <raster> if u can get a 2x speed up on 90% of yoru work
[08:47:07] <AV500> raster: yes
[08:47:08] <raster> and ok - on a bad day make a tiled buffer to linear conversion 50% slower
[08:47:14] <raster> you win overall - big time
[08:47:31] <raster> so it really then depends on your expected workload
[08:47:36] <AV500> so, code it, the evenings young :-)
[08:47:45] <raster> and your workload then would need to include a lot of scaling, rotation etc. etc.
[08:48:03] <raster> as such.. i have yet again even reduced evas's reliance on scaling while drawing
[08:48:07] <raster> it now has a scale cache
[08:48:08] <AV500> you end up doing SW 3d stuff :-)
[08:48:19] <raster> commonly scaled src data gets cached after use as post-scaled data
[08:48:30] * xpg (n=pf@0x55510a11.adsl.cybercity.dk) has joined #beagle
[08:48:32] <raster> thuis your draw is a simple blit or blend without scaling.. for commonly scaled data
[08:48:42] <AV500> ok

[08:48:48] <raster> so tiled mem is even less useful as i added a fast path that would bypass its usefulness :)
[08:48:59] <raster> furan: really? cool! and is it successful?

[08:49:19] <raster> AV500: yeah. tiled stuff.. will end up a sw engine for 3d
[08:49:34] <raster> AV500: but then again.. that has some benefits... as the world moves more to "more generic multi-core"
[08:49:37] <raster> things like larabee
[08:49:39] <furan> yes, I helped design the dwm (the desktop compositor) among other things, fun work
[08:49:41] <raster> and cortex-a9
[08:49:44] <raster> and so on
[08:49:45] <furan> just ordered a beagleboard, should be here tomorrow
[08:49:51] <furan> (for hobby)
[08:49:51] <raster> a software 3d enigne becomes highly interesting
[08:50:08] <recalcati> koen: ping
[08:50:08] <raster> as now the software logic ports to most multi-core engines
[08:50:14] <AV500> every tile his core :-)
[08:50:21] <raster> the cool bit is - the cores, when not doing gfx, are generic proc cores.. and can do other stuff.
[08:50:30] <raster> seriously.. u know how powervr works?
[08:50:33] <raster> it literally does that
[08:50:43] <raster> it doesnt have enough cores to cover 1 core per tile...
[08:50:51] <raster> but it actually splits your output buffer into tiles
[08:50:59] <raster> and load-balances assigning tiles to cores
[08:51:06] <raster> and a core then does the rendering for that tile
[08:51:08] * Yuvi_ (n=yuvi@resnet-241-44.resnet.umbc.edu) has joined #beagle
[08:51:14] <raster> if u draw complex stuff that fits inot just 1 tile
[08:51:29] <raster> it can be no faster than doign the same thing over many more pixels - spread over many tiles
[08:51:39] <AV500> btw, ti told me yesterday that sgx being "slow" can't be
[08:51:41] <raster> because if it all just fits into 1 tile.. you make no use of the multipel cores.
[08:51:46] <recalcati> koen: ping pong
[08:52:06] <raster> AV500: dunno. i have a rendering engine that shows that it is slow :)
[08:52:15] <raster> trolltech guys do too
[08:52:22] <raster> and from what i hear.. movial guys do too
[08:52:50] <raster> furan: cool! so coming to linux? or still in windows land?
[08:53:19] <raster> AV500: i sent full source, ipk's and more to pratheesh
[08:53:25] <raster> and since i sent them i have heard nothing back
[08:54:20] <raster> so al i can conclude is that either TI lost interest in powervr ands its performance
[08:54:40] <raster> or there simply is no known solution to it or there is a block at some point stopping further investigation
[08:54:43] <furan> still in windows land for career, but might write tiny os on beagleboard for fun
[08:54:48] <raster> or i am simply an idiot for expecting too much of the sgx
[08:54:49] <raster> :)
[08:55:06] <Pavlov> probably a combination of the above :)
[08:55:30] <lcuk> raster, how come we have fancy gl oriented demos then - is that its one very manufactured area where it can shine?
[08:56:10] <lcuk> and we are just over pushing it trying to work on desktop sized 2d stuff?
[08:56:20] <raster> lcuk: my guess is that they dont tickle the slow bits of ths sgx
[08:56:27] <raster> very much manufactured to avoid them
[08:56:41] <raster> all the demos i saw for example.. judiciously avoid any form of blending
[08:56:49] <lcuk> agreed, the powervr started as small mobile phone res stuff
[08:56:53] <eFfeM> recalcati: that patch gives 720p with your tv ?
[08:56:57] <raster> the sgx has a nice little trick called early-z-test
[08:57:14] <raster> where it calculates the x value and compares to the zbuffer BEFORe it ever calculates anythign else
[08:57:16] <raster> and throws out the op
[08:57:22] <raster> that not useful for 2d
[08:57:24] <eFfeM> recalcati: if so perhaps post to the mailing list together with your boot args
[08:57:25] <Pavlov> raster: you ever talk to mandrake these days?
[08:57:35] <raster> as u can do such things in software before it hits the sgx anyway
[08:57:54] <raster> and i know i do it before it hits gles (the evas softwre engine does it too itself to avoid overdraw where it can)
[08:57:55] <lcuk> raster, could be, but its not the way to design your system ;)
[08:58:07] <recalcati> eFfeM: tryed by now on monitor, but this evening I'll try on Bravia 32W4000 and Samsung 32A336
[08:58:18] <recalcati> but fbset says 74.25
[08:58:33] <raster> alpha blending is a order of magnitude nastier that simple fills
[08:58:35] <raster> or blits
[08:58:47] <lcuk> raster, just means our nurtured software routines get to live for another day :)
[08:58:51] <raster> as it is not just read src -> write dest, or "write fixed val to dest"
[08:58:59] <raster> its read src, read dest, calc blend, write dest
[08:59:05] <raster> which tends to screw with mem accesses more
[08:59:17] <raster> but yes
[08:59:29] <raster> the software routines seems to be plouging along still nicely.. and live for another day.
[08:59:37] <raster> i really WISH the sgx was doign better
[08:59:48] <Pavlov> mem access on the sgx seems to be the killer
[08:59:50] <raster> i would have loved to break out of the limits software places (in tersm of practicality)
[09:00:21] <raster> Pavlov: and nah. dont talkt to mandrake. havent for almost 10 years (since 2001) even back then i didnt talk too much in 2001
[09:01:23] <raster> Pavlov: yeah. right now it seems.. to me.. to be that the sgx is only able to access mem at a fraction of actual memory bandwidth
[09:01:29] <raster> so things that calculate stuff in shaders
[09:01:38] <raster> or use small simple textures that fit int he sgx caches work fine
[09:01:41] <Pavlov> heh, was just thinking back the other day to a talk i gave at the atlanta linux enthusiasts back in 98 and thought of him for some reason
[09:01:46] <raster> once u have large textures
[09:01:49] <Pavlov> yep
[09:01:57] <raster> lots of mem access (blending) and really hammer it
[09:01:58] <Pavlov> thats what i've seen too
[09:01:59] <raster> it bogs down
[09:02:16] <raster> a shader can calculate some funky proceedural texture faster than it can fetch texels
[09:02:25] <raster> thus a lot of the demso use very simply small lo-res textures
[09:02:32] <raster> and a lot of shaders
[09:02:34] <raster> and no blending
[09:02:37] <raster> in 2d land
[09:02:43] <raster> i absolutely hammer through using textures
[09:02:46] <raster> pixels everywhere
[09:02:46] <Pavlov> i hold out more hope for newer chipsets
[09:03:04] <raster> and the cpu can hammer through that to the point where most of the time its simply memory-bound
[09:03:14] <raster> so if the cpu is memory bound

[09:03:16] <raster> and the sgx is too
[09:03:23] <raster> the sgx can at best equal the cpu
[09:03:31] <raster> (given both have really good algorithms)
[09:03:51] <Pavlov> yep
[09:03:55] <AV500> yep
[09:03:57] <raster> if the sgx suffers form being underclocked or gets second-rate mem access... then i can understand how it is at a disadvantage compared to the cpu doign the same stuff
[09:04:29] <raster> as we were discussing before - tiled memory would improve some ops in the cpu. better cache choerency. and the sgx definitely can pull ahead here. my benchmarks show that.
[09:05:12] <raster> but when it comes back to the simpler stuff (fills, blits and non scaled blends) the cpu either catches up to totally beats the butt off the sgx

[09:06:39] <furan> I wonder if it could be argued then that the only usefulness in that scenario for doing those operations on the gpu is memory locality (does powervr/a8 share memory or does the pvr have dedicated memory?)

[09:09:42] <raster> just like any smp-style cpu core would be

[09:10:06] <mib_mngmu9> hi, I was wondering how much the beagle board weighs - I couldn't find the information in the datasheet

[09:23:38] <raster> speaking of what snew
[09:23:48] <raster> does anyone here really know the kernel bootsrap proceedure well?
[09:23:54] <raster> i am having.. unhappy fun times
[09:24:09] <raster> where the bootloader just cant get the cmdline params to the krenel
[09:24:31] <raster> i need to offset the kernel start by + 0x8000 to make it work, but this kills boot params
[09:27:37] <AV500> what does this offset do?
[09:28:33] <raster> well it tells haret where ram starts
[09:28:50] <raster> i just tell it that starts 0x8000 later
[09:28:57] <raster> 0xa0008000
[09:29:01] <raster> instead of
[09:29:04] <raster> 0xa0000000
[09:29:21] <raster> but it seems that the bootloader auto-offsets the kernel by 0x8000 anyway when putitng it into ram
[09:29:55] <raster> ram base 0xa0000000 works for one kernel, but not another
[09:30:44] <AV500> we had something similar in the past, no idea if we resolved it though
[09:30:47] <DJWillis> raster: either, the systray module sounds interesting.
[09:32:45] <raster> DJWillis: it looks rather boring
[09:32:54] <raster> the wallpaper selector.. u really eant to see it in action
[09:32:56] <raster> its not screenies
[09:33:02] <raster> its how it... moves!

[09:35:37] <DJWillis> raster: I'll look to build it in sometime, E does look nice and work well on the Pandora, struggles a little in 128 but with 256meg it works really well.
[09:35:47] <DJWillis> khasim: good morning sir.
[09:35:49] <recalcati> koen: hd270 patch: http://widget.mibbit.com/pb/WPbAWP
[09:36:01] <raster> DJWillis: it should be ok in 128. maybe you need to tone down some config?
[09:36:04] <koen> recalcati: could you make it a p1 patch and mail it?
[09:36:15] <raster> DJWillis: it rip roars along on my overo
[09:36:30] <raster> hmm
[09:36:34] <raster> overo has 256m actually
[09:36:39] <raster> it also worked wel on my bb
[09:36:40] <raster> 128m
[09:36:52] <raster> but the new wp browser is much mroe device-like
[09:37:05] <raster> u need to load the setup - wallpaper 2 module
[09:37:12] <raster> and use the wallpaper 2 settings
[09:37:12] <DJWillis> raster: It has always been fine for me in fairness in 128, it's just 'user reports' that say it slows down and dies (without swap).
[09:37:45] <raster> hmmm
[09:37:50] <raster> thats very odd
[09:37:52] <raster> it shouldnt
[09:38:07] <raster> i pay pretyt close attention to memo usage
[09:38:14] <raster> i'm still waiting for my panny...
[09:38:21] <raster> damn production taking forever
[09:38:22] <koen> DJWillis: we are still launching matchbox and gpe stuff in the background, need to tweak the session scripts
[09:38:31] <DJWillis> raster: my money is on the apps being run with it to be honest, as the newest Pandoras are all 256 I never looked into it that much.
[09:38:50] <raster> DJWillis: if they are runing firwfox etc. i can definitely understand
[09:38:59] <recalcati> yeslike this ? http://widget.mibbit.com/pb/wT8MI1
[09:39:00] <DJWillis> koen: ahhh, interesting, so a little bloat in there then, that explains a few things.
[09:39:01] <raster> when memory pressure hits and e cant alloc ram it will become unstable
[09:39:04] <raster> for sure
[09:39:08] <raster> and efl is alloc-happy
[09:39:16] <raster> its ammlocing somehting (and freeing it) continually

[09:40:51] <koen> DJWillis: maybe entrance would work as well
[09:40:59] <raster> DJWillis: are the panny guys still doing their "lets re-invent .desktop files and so on" sutff?
[09:41:37] <koen> recalcati: yes like that, could you mail it (as an attachment) so have less change of messing up whitespace?
[09:41:47] <raster> beware entrance
[09:41:51] <raster> it is unloved/maintained
[09:41:56] <DJWillis> raster: it now dumps desktop files ;-) but yep, sort of ;-)
[09:42:21] <DJWillis> raster: not something I am touching (other then building the deamon/lib into our images).
[09:42:37] <raster> DJWillis: hehehe. ok. well lets let them. once i get a panny i'll make sure it has a full oe distro on it i can do hacking on.
[09:42:42] <koen> DJWillis: btw, gpe-dm isn't the greeter, gpe-login is :)
[09:42:54] <recalcati> yes
[09:43:32] <koen> systray is in OE now
[09:43:33] <DJWillis> raster: you will be pleased to know it is full OE with no messing, made sure of that from day one, all the additions are from an overlay but no need to carry them if you don't want.
[09:44:15] <DJWillis> koen: very true
[09:44:16] <raster> DJWillis: cool. tho i'll just build my own sinc ei have oe under control here and wel in hand
[09:44:23] <raster> as long as any panny changes are in oe dev
[09:44:25] <raster> i'm a happy man
[09:45:28] <DJWillis> raster: as I would expect, all the basic support is in OE, some stuff is in the overlay (wifi driver etc.) but I want to move that over anyway as it's hardware platform stuff not 'branding' rubbish, i'll keep that in the overlay.

[09:49:18] <raster> anythign branding-wise - overlay seems fine
[09:49:28] <raster> basic functionality should definitely merge in
[09:49:31] <DJWillis> raster: not yet, it's a TI driver module (that we had to hack up) and a mess, think PowerVR drivers rather then something nice and clean ;-)
[09:49:43] <DJWillis> raster: my view as well.

[09:51:09] <raster> DJWillis: ewww! so no source?
[09:51:24] <raster> or just ugly like powervr.. but with source-level ugliness too
[09:51:25] <raster> ?
[09:51:49] <DJWillis> raster: source but it's a mess ;-) (only firmware is closed). Build system from the arse end of naff ;-)
[09:52:04] <raster> oooh ouch
[09:52:06] <raster> one of those
[09:52:25] <DJWillis> Also lacks stuff like Wireless extensions suport but working on that.
[09:53:13] <raster> aaaah
[09:53:18] <raster> so limited in functionality
[09:53:22] <raster> its a ti wifi ship?
[09:53:24] <raster> chip
[09:53:32] <raster> is it one of those wifi+bt things
[09:53:37] <raster> or just wifi?
[09:53:51] <DJWillis> raster: in time a clean patch or out of tree module is the way to go, for now out of tree module is all we will have for release. TI1251 module (so BT also).
[09:54:14] <DJWillis> BT is fine for the most part, works, a few little rough edges etc.
[09:55:00] <DJWillis> raster: for release we will (I hope if I can sort it) have Wireless Extention support going to no issues with function then for the most part.
[09:55:53] <raster> DJWillis: hmm thats sucky. so much function stuffed into so much ugliness
[09:56:27] <DJWillis> raster: yep, it does suck
[09:57:12] <raster> well beating it into shape and gettign it nto upstream kernel is the right way
[09:57:15] <DJWillis> At least the driver source is GPL, that's better then nothing but it needs a real skilled uplift to get upto scratch and ever within sight of mainline ;-).
[09:57:28] <raster> at least at an early stage merging it with the current omap3 linux git tree
[09:57:31] <raster> both are ti things
[09:57:34] <raster> so mayaswell marry them
[09:57:38] <DJWillis> raster: it all comes down to time.
[09:57:42] <raster> yeah
[09:57:47] <raster> totally grok that
[09:57:59] <DJWillis> raster: I can't see Tony touching it with a big stick ;-)
[09:58:03] <raster> and time spent on something with "no financial gain" is.. espensive tim3e
[09:58:31] <DJWillis> raster: when your just a dev hacking on this for fun (not money) then jobs like that loose appeal.
[09:58:40] <raster> sure
[09:58:42] <raster> agreed
[10:02:37] <recalcati> I have another stupid patch to delay rootfs mount to allow nfsroot mount, I send you ?
[10:02:37] <koen> DJWillis: you can try getting it in the staging tree thru greg KH
[10:03:14] <koen> DJWillis: you would have to buld your kernel with TAINT_CRAP enabled, though :)
[10:03:34] <recalcati> koen: is to allow first usb to eth interface to be recognized and then go on
[10:03:37] <AV500> raster: speaking of which, it there anything more clever for blit_rotate than just brute force?

[10:04:58] <raster> beyond tiles to improve cache coherency... nothing i can think of
[10:05:30] <AV500> I could think of reading a couple of rows in parallel so that coumns have more than 1 pixel output at the same time
[10:05:36] <recalcati> koen: I had but the dhcp has to go in timeout for 2 or 3 minutes and then trying again it was be able to go on, instead with this patch only 5 second dealy
[10:05:37] <raster> the best i can possibly think of is 1. read src always in-order
[10:05:42] <raster> (ie left ro right) where you can
[10:05:46] <raster> and just vary write direction
[10:06:11] <recalcati> I tried rootwait
[10:06:12] <AV500> well, actually, the omap3 DMA should do rotation as well :-)
[10:06:32] <raster> AV500: does it?
[10:06:35] <recalcati> dhcp is before, isn't it
[10:07:08] <recalcati> I sent anyway, do what you prefer
[10:07:33] <raster> though i break that rule to do 32->16bpp in evas
[10:07:41] <raster> as i merge 2 pixels inot 1 for write
[10:07:47] <raster> so i write in sequence
[10:07:51] <raster> i read out-of-sequence
[10:08:05] <AV500> why not read 2 lines at the same time?
[10:08:15] <AV500> the dma controller has more than 1 mem line open at a time
[10:08:23] <AV500> err, the sdram controller
[10:09:55] <raster> that can be done
[10:09:58] <raster> i just havent done it
[10:10:00] <raster> :)
[10:10:20] <raster> its one of my less "concerning" bits of the pipeline i guess
[10:11:51] <AV500> raster: yes, DMA can do 90?? rotation
[10:12:04] <raster> cool
[10:12:08] <raster> and dma understand the pagetable?
[10:12:11] <raster> (mmu)
[10:12:12] <raster> ?
[10:12:30] <AV500> I think not, but in my case I dont care, it is at the output stage
[10:12:36] <AV500> fbmem is not mmu
[10:12:43] <raster> aaah
[10:12:44] <raster> sure
[10:12:50] <raster> well it is
[10:12:52] <raster> but its linear
[10:12:55] <raster> in 1 chunk
[10:13:02] <raster> it still is mapped in so uc an write to it
[10:13:07] <AV500> yesyes
[10:13:22] <raster> i wish dma engines grokked the mmu
[10:13:30] <AV500> isp does
[10:13:59] <raster> is it "open" ? (and programmable)?

[10:17:18] <AV500> or resize a user buffer
[10:17:24] <raster> AV500: sure
[10:17:27] <raster> thats what i was thinking
[10:17:40] <raster> is the isp like the dsp - ie has a command processign engine
[10:17:44] <raster> or a fixed pipeline?
[10:17:53] <raster> (ie rescaler etc.)
[10:17:59] <AV500> fixed more or less, it does all the cam stuff

[10:20:05] <Skaggio> Hi everybody.....
[10:20:09] * raster pokes his tongue out at the isp :-P
[10:20:15] <Skaggio> I'm new herearound...
[10:21:09] <Skaggio> I tried to join and post to the BeagleBoard group unsuccesfully...
[10:21:24] <Skaggio> So I'm back here with my question...
[10:21:35] <AV500> ISP runs raster through naughty pixel correction!
[10:21:44] <Skaggio> I will receive my Beagle Board in the next few days
[10:21:44] <AV500> Skaggio: ask
[10:21:54] <recalcati> mplayer hangs the system and I continue hear a piece of audio of about 1 second forever. see details of video playing: http://widget.mibbit.com/pb/1UoMlT
[10:22:13] <Skaggio> My project is to develop a simple (I hope) application: I need to
[10:22:23] * tzhau (n=tzhau@dsl-245-80-220.telkomadsl.co.za) Quit (Connection timed out)
[10:22:28] <Skaggio> receive a video (and audio) stream via TCP/IP, pass it to the
[10:22:37] <Skaggio> BeagleBoard through the USB, decode it and render it to the video and
[10:22:44] <raster> AV500: my pixels are too naughty for your isp! naughty overload
[10:23:20] <Skaggio> audio outputs. The input stream will be a MJPEG stream (I could evaluate MPEG too of course), the resolution will be in the range from CIF to D1, the frame rate down to few fps (1-2 or something like that).
[10:23:23] <Skaggio> I will also need to manage the audio input and send it to a TCP/IP channel.
[10:23:32] <Skaggio> I saw there are many projects (e.g. GStreamer) out there...
[10:23:54] <Skaggio> Can you suggest me the EASIEST, FASTEST and supported way to compile a STABLE, GOOD WORKING application with the requirements reported above?
[10:24:01] * tzhau (n=tzhau@dsl-245-80-220.telkomadsl.co.za) has joined #beagle
[10:24:07] <koen> Skaggio: upgrade your uboot
[10:24:07] <Skaggio> Thank you in advance for any suggestion!
[10:24:18] <AV500> Skaggio: no
[10:24:24] <AV500> unclear reqs
[10:25:45] <Skaggio> av500: Why unclear?
[10:27:21] <Skaggio> koen: upgade with what?
[10:27:27] <raster> gah! wtf has git donw now
[10:27:40] <AV500> naughty commit correction
[10:27:52] <koen> Skaggio: with a newer version
[10:27:56] <raster> nah
[10:28:03] <raster> its found conflicts in files i have never touched before
[10:28:05] <raster> like qte
[10:28:08] <raster> and alsa
[10:28:25] <koen> raster: packages -> recipe move?
[10:28:34] <raster> koen: bugger! yes.
[10:28:38] <raster> it would seem so
[10:28:41] <Skaggio> koen: :D With what inside?
[10:28:43] <koen> git doesn't track directories -> pain
[10:28:47] <AV500> git knows that qte and alsa are "conflicts"
[10:28:50] <raster> did everything move?
[10:29:02] <koen> raster: git mv packages recipes
[10:30:41] <raster> methinks my git tree was just about to get totally fucked
[10:30:43] <raster> this is not good
[10:31:06] <raster> why does git hate me so and fuck up like 1000x more often than svn has ever done?
[10:31:57] <raster> aaargh!
[10:32:16] <koen> raster: because linus tells people to fix stuff by hand before he pulls
[10:32:31] <koen> raster: so git lacks basic conflict resolution and merge algos
[10:32:35] <recalcati> Skaggio: I'd like what you say, input/output from to tcp for audio/video . This has to work in omap3 family and in dm365

[10:33:21] <koen> raster: I dislike git for that reason, but one isn't allowed to critize it
[10:33:36] <recalcati> koen: thx
[10:33:56] <raster> koen: the problem is i think this whole branch culture
[10:34:06] <raster> everyone having to live in their own little branch world
[10:34:11] <koen> raster: exactly
[10:34:15] <raster> and so when yuou finally have to "meet up" with others
[10:34:25] <raster> everything falls apart if anything major happened
[10:34:31] <raster> if everyone weer forced to live in "head"
[10:34:50] <raster> and do their work in a way that.. it lives in head.. works butr doesnt disrupt anyone but themelves
[10:35:02] <raster> (eg its a configure --enable option or whatever)
[10:35:11] <raster> then life is so much simpler... stuff works!

[10:51:50] <Skaggio> Any suggestion?
[10:52:25] <AV500> mplayer, ffmpeg
[10:53:07] <AV500> gstreamer
[10:53:26] <AV500> cat
[10:53:47] <Skaggio> av500: the best choice to do it fast?

[10:56:12] <AV500> well, to try mplayer or ffmpeg should take almost no time, I guess both are part of std BB distros.
[10:56:27] <Skaggio> great!
[10:56:30] <Skaggio> :D
[10:57:26] <Skaggio> av500: Cna they manage a continuous TCP/IP stream (copming from USB port)?
[10:57:35] <Skaggio> copming = coming
[10:57:47] <Skaggio> Cna = Can
[10:59:08] <koen> 1 bit/hour is still continuous
[10:59:12] <Skaggio> av500: Otherwise: what steps should I do to manage a continuous stream?
[10:59:42] <AV500> Skaggio: what protocol?
[10:59:51] <AV500> and I guess you mean eth over usb, right?
[10:59:55] <AV500> and I guess you mean ethernet over usb, right?
[11:00:15] <AV500> you are still unclear in your specs
[11:00:38] <Skaggio> koen: 1-2 fps with resolution in CIF to D1 range, mean quality
[11:02:08] <tomba> koen: DMAI?
[11:02:17] <AV500> Skaggio: at that speed you can stream uncompressed images
[11:02:53] <Skaggio> AV500: eth over USB... More or less: Beagle Board will be a sub system. The main system will have to receive data from Ethernet and send it to the Beagle Board
[11:02:56] <eFfeM> koen, recalcati, thanks for the r22 patch, will try it tonight with my TV, if I can kick my family from it :-)
[11:03:15] <AV500> why 2 systesm, the bb can handle eth nicely

[11:03:49] <koen> tomba: https://gstreamer.ti.com/gf/project/dmai/
[11:04:46] <Skaggio> AV500: I do have bandwidth limitations, I could also try higher frame rates
[11:04:47] <tomba> ah
[11:06:20] <Skaggio> av500: BB can connect to ehternet? by using the USB channel, correct?
[11:06:45] <AV500> by using an usb to eth converter
[11:08:37] <Skaggio> av500: Ok. Now let's see inside the BB: can the fffmpeg and/or mplayer manage the stream directly?
[11:09:10] <AV500> Skaggio: what stream? what protocoll?
[11:09:35] <Skaggio> av500: MJPEG stream, TCP/IP protocol
[11:10:23] <AV500> Skaggio: yes, tcpip is the trnasport, but what is the streaming protocoll? raw mjpeg?
[11:10:49] <AV500> what is the container? avi? mp4?
[11:10:57] <mpoullet|work> recalcati: ping
[11:12:30] <Skaggio> Skaggio: Let's suppose avi
[11:13:30] * joesensport (n=joesensp@218.242.229.234) has left #beagle
[11:13:32] <AV500> now we still miss the streaming protocoll, for avi that would be http
[11:13:34] <koen> raster: testing 39886 now
[11:13:58] <AV500> ffplay 192.168.1.1/test.avi should work
[11:14:06] <AV500> ffplay http://192.168.1.1/test.avi should work
[11:14:17] <AV500> same for mplayer
[11:14:42] <AV500> but avi is not really the 1st choise for streaming
[11:16:28] <Skaggio> av500: What about mp4?
[11:18:37] <AV500> not good
[11:19:49] <Skaggio> av500: What's your sugestion? :D
[11:22:45] <koen> raster: is /usr/lib/enlightenment/preload/e_precache.so important?
[11:23:08] <AV500> Skaggio: what is your application, what do you stream? a finished file? camera images?
[11:23:37] <raster> koen: only if you use the preload option
[11:23:52] * koen packages it
[11:24:03] <Skaggio> av500: camera images. It could an analogic interlaced camera or an IP camera
[11:24:42] <AV500> the ip camera already has a streaming format, no?
[11:27:21] <Skaggio> av500: I do not actually know the IP camera model...

[13:00:36] <recalcati> ffplay not present
[13:01:16] <recalcati> mpoullet|work: what is the error?
[13:01:23] <mpoullet|work> in the E revision, see Table 2 - "Video Format Timings - Detailed Sync Information"
[13:02:46] <tomba> I only found version B from the net =(

[13:08:22] <recalcati> mpoullet|work: thx I change and try with: monitor Samsung SyncMaster 2032BW, then Sony Bravia 32W4000, Samsung 32A336
[13:08:23] <mpoullet|work> recalcati: but if you try an HDMI analyser, it will complain

[13:09:25] <mpoullet|work> recalcati: cool! I love HD TV sets
[13:10:06] <mpoullet|work> koen: perfect!
[13:10:13] <recalcati> mpoullet|work: a question , it is possible that Samsung 32A336 doesn't display anything ? maybe due to HDCP not supported by BB ?
[13:10:50] <mpoullet|work> recalcati: I haven't tried Samsung yet, only Sony, Philips, LG and Toshiba
[13:11:06] <mpoullet|work> but it could be a polarity issue of the pulses
[13:11:28] <eFfeM> will also try with philips tonight or tomorrow
[13:14:21] <recalcati> mpoullet|work: HDCP can be a problem, isn't it ?
[13:14:45] <mpoullet|work> recalcati: yes for sure, it could be a problem too
[13:16:20] <AV500> raster, reading 4 lines at a time and therefore outputtin 4 pixels in a row increase the speed from 41ms to 16 for 800x480, not bad

[13:21:35] <tomba> current DSS2 has omapfb.vram option that you can use to pre-alloc memory for all the framebuffers. I'm thinking of removing that, and leaving support for fb0 only. Anyone sees a problem with that? You can still allocate memory for video planes with SETUP_MEM ioctl, or via sysfs.

[13:26:31] <AV500> tomba: fine with me, we have already removed all other static buffers except fb0
[13:27:25] <AV500> btw, is there a simpler way to setup an overlay with userptr mem than going via v4l?
[13:27:37] <koen> tomba: poke zuh and mru before doing that, so they can change xf86-video-omapfb and omapfbplay :)
[13:28:17] <tomba> koen: xv should work fine, it allocates mem with SETUP_PLANE. omapfbplay doesn't allocate, I think, so the userspace would first need to do allocating with echo
[13:28:41] <tomba> AV500: what's userptr? displaying app allocated memory on the screen?
[13:29:39] * tzhau (n=tzhau@dsl-245-80-220.telkomadsl.co.za) has joined #beagle
[13:29:51] <tomba> koen: but if one needs to prealloc the video planes, he can add the allocations to system init scripts. that shouldn't be too different from setting kernel boot parameters
[13:31:02] <sakoman_> koen: no, but I've never really looked
[13:31:35] <koen> sakoman_: ok, I was looking for some more pixels :)
[13:31:36] <sakoman_> perhaps there are others in the same "family" from Samsung
[13:32:04] <recalcati> Samsung SyncMaster 2032BW sometimes passing from u-boot to kernel looses the sync and desn't display anything

[13:32:51] <AV500> e.g. something that the DSP decoded into
[13:33:04] <tomba> AV500: fb framework doesn't support that. you can, of course, allocate a large framebuffer and use that with panning, if you need multiple buffers
[13:33:40] <koen> sakoman_: sadly UPS is being slow with getting my palo43+lcd to here
[13:34:04] <sakoman_> koen: I agree, 480 x 272 just isn't enough pixels!

[16:55:17] * ArteK (n=Artur@81.15.241.96) has left #beagle
[16:56:14] <zuh> hmm, actually, I'm not sure that even that is true...
[16:57:42] <koen> well, I'm not sure either, I just want to play D1 sized movies on a 640x480 display, without scaling the whole thing
[16:58:46] <koen> where 'scaling whole thing' means a 1024x768 framebuffer scaled to a 640x480 output
[17:00:39] <koen> zuh: I suspect I can get around it by using the ISP resizer to resize it before hitting XV, but getting a working driver for that is proving a bit difficult
[17:01:07] <zuh> in QueryBestSize we check what we can output (just cap to viewport), in QueryImageAttributes we just calculate the data size for given resolution and in the actual plane setup we round the source (ie. the plane memory allocation) to nearest 16 divisible.
[17:02:01] <zuh> So my guess would be that the plane allocation fails due to <something>
[17:02:14] <zuh> or plane memory allocation rather
[17:02:55] <zuh> Unless mplayer treats the QueryBestSize as size for the src...

[17:14:42] <zuh> Yeah, actually judging from the mplayer code it's this: http://cgit.pingu.fi/xf86-video-omapfb/tree/src/omapfb-xv.c#n269

[18:26:57] <koen> us -> eu is cheaper (especially with miles) than eu -> us
[18:27:21] <ds2> Eurostar to the Med, then crew as a tanker from med to the US
[18:27:23] <koen> especially with the current $150 'security' tax for US airports
[18:27:44] <sakoman_> ds2: if you want to stay the whole season you can get a "job" as a campground host
[18:27:58] <sakoman_> they were begging for them in Lassen last year
[18:27:59] <suihkulokki> backpacking means walking and public transports - I've heard neither is really practical in the us
[18:28:03] <ds2> sakoman_: like the other 234092314849023848234923890423849082394 folks aren't considering that right now
[18:28:09] <zuh> koen: That's mplayers fault then, it should not assume that the XV adaptors maximum frame size is capped to the screen
[18:28:22] <koen> zuh: yeah
[18:28:35] <sakoman_> ds2: it doesn't pay anything, so the real number is near zero :-)
[18:28:56] <ds2> sakoman_: it is legitimate shelter and access to water/bathroom facilities
[18:29:04] <ds2> better then hanging around city pavement
[18:29:06] <GregorR-L> suihkulokki: Walking is only impractical because the US is big and sparse, public transportation is only good in big cities.
[18:29:20] <sakoman_> ds2: that's why I moved to the middle of nowhere :-)
[18:29:31] * koen has been caught too many times by the "walkway end at random points" in the US
[18:30:26] <ds2> sakoman_: but the middle of nowhere is getting developed bit by bit
[18:30:40] <ds2> besides, aren't the cheap plots of land in your area all but gone?
[18:30:44] <sakoman_> koen: if you pick the right walkway you can go for 4,240 km
[18:30:59] <koen> ds2: with all the gadgets inside sakoman_ house you can equip a small country :)
[18:31:00] <sakoman_> ds2: they are getting cheaper by the day :-(
[18:31:32] <sakoman_> But not as good as when I bought ($2K/acre)
[18:31:53] <ds2> koen: won't help you if Lassen decides to go off
[18:32:14] <ds2> I'll get an acre for $4K
[18:32:29] <sakoman_> yeah, I live on top of an ancient pyroclastic flow
[18:32:49] <ds2> is your stuff really that ancient? not the stuff from the early 1900s?
[18:33:23] * koen is wondering whether to make an apple pie or not

[18:38:45] <sakoman_> summers are 10-20% RH
[18:38:57] <sakoman_> makes patio misters work really nicely!

[18:41:35] <sakoman_> It can be 30F cooler up there
[18:41:50] <sakoman_> oh, yes! at about 800 feet
[18:41:58] <ds2> cuz part the humidity/mosquitos seems to be from the melt run off

[18:43:19] <Spyro> Hi folks
[18:43:41] <eFfeM> hi
[18:43:47] <Spyro> Im trying to find out the part # for the two unpopulated LCD headers on my Rev C
[18:43:49] <ds2> sakoman_: that makes sense now... used to know someone who had a place up there; but his place is up at around 4K-5K
[18:44:08] <Spyro> I need both headers (pref. keyed) and sockets (carriers + pins)
[18:44:13] <eFfeM> spyro check the manual, i think they are fairly standard
[18:44:14] <ds2> Spyro: why P/N? just look for a 0.050 pitch 10x2 headers spaced at 0.050"
[18:44:23] <ds2> they are standard parts
[18:44:35] <Spyro> ds2: because I havent got anything accurate enough to merasure them :)
[18:44:51] <sakoman_> ds2: I wanted a place in the banana belt - high enough to avoid the winter frost & fog, but low enough to avoid the snow
[18:44:52] <ds2> Spyro: no, just look at the catalog.. or use the selector on Digikey's site
[18:44:58] <Spyro> you can buy them as a single 'block' connector ?
[18:45:14] <ds2> I got mine from digikey using their selector
[18:45:22] * Spyro lives in the UK and digikey can cost a fortune in customs (equated to 30% extra tax on my bb) :-(

[18:45:48] <hrw> Spyro: 22% here
[18:46:01] <Spyro> lucky bastard :)
[18:46:19] <Spyro> I'll get them from RS now I know what they are
[18:46:28] <ds2> sakoman: heh... that sounds close to what I would like... but I don't need a grid connection either
[18:46:44] <Spyro> Did you mean (above) that you can get both headers in a 'block' ?
[18:46:53] <hrw> Spyro: consider then getting EVBeagle instead?
[18:46:55] <sakoman_> ds2: I installed solar & wind
[18:47:07] <Spyro> god I waish we had digikey over here. their catalogue is amazing
[18:47:17] <hrw> Spyro: anyway I got BB with invoice for 10$ so no customs at all
[18:47:26] <ds2> sakoman_: do you have a grid connection?
[18:47:30] <Spyro> hrw: I have my beagle. (despiute tax :( )
[18:47:32] <sakoman_> ds2: yes
[18:47:55] <Spyro> hrw: customs 'inspected' mine and charged 30 ukpp for the privilege
[18:47:56] <ds2> sakoman: doesn't that add to the property tax? i.e. the county sees it as a higher value land?
[18:48:33] <sakoman_> my taxes didn't go up, but I did claim the fed & state rebates
[18:49:09] <ds2> I mean just the grid connection
[18:49:20] <sakoman_> Oh, I doubt it
[18:49:27] <ds2> wind/solar aren't really (IMO) a permenant improvement to the land
[18:49:37] <eFfeM> hmm, booting .29 r24 get a train of omapdss/clock errors, reboot then everything is ok
[18:49:55] <sakoman_> they may assume a lower value/acre for no grid, so you might be right
[18:50:51] <eFfeM> anyone knows the proper u-boot incantation for 720p output ?

[18:53:47] <ds2> with a septic you are selfcontained, once you get fooled into getting on grid, on sewer, on city water then you are stuck with a permanent liability stream :(
[18:53:56] <sakoman_> koen: did you have this issue?
[18:54:46] <sakoman_> ds2: in the middle of nowhere, things like sewers, water mains, and cable tv are non-existent!
[18:55:38] <ds2> sakoman: it is a matter of time before some idiot developer will try to sell that and the idiots in the county then would agree on a general levy to fund "improvements"
[18:56:13] <sakoman_> hope not!

[19:32:41] <eFfeM> xpg probably the right place, but I can't help; only clutter BB gives to me is wrt the cables on my desk

[19:35:48] <lcuk> are the fonts blurry on the test text zooming example

[19:37:03] <lcuk> ok, so that rules out developer error :P (at least on your part ;))
[19:37:08] <xpg> hehe
[19:37:35] <xpg> unfortunately
[19:37:36] <lcuk> might be worth taking some screenshots and putting a bugreport in
[19:37:48] <lcuk> what resolution are you rendering to?
[19:38:04] <xpg> Yeah, I was about to to that, but just wanted to hear in here if anyone had experienced the same
[19:38:16] <xpg> the framebuffer is running at 1024x768
[19:38:22] <lcuk> well i noticed they werent as crisp as the stuff i was doing
[19:38:51] <lcuk> they looked drawn on and scaled rather than proper rendering
[19:39:22] <xpg> They look fine here, until it gets garbled
[19:39:27] <eFfeM> koen, is there also a setting for 720p50 ?
[19:39:41] <eFfeM> current value is 720p60
[19:39:58] <xpg> I have the feeling that it is caused by changed the content of a label, but I have to do some testing to verify it

[21:11:29] <trace_guy> where you get an ETM header ?
[21:11:38] <ds2> you by a EVM board :D
[21:11:40] <ds2> buy
[21:11:51] <ds2> Spyro: not that I know if. I just have a parallel board
[21:11:59] <ds2> not many cheap LVDS LCDs around
[21:12:02] <trace_guy> sure, so if you buy it, then JTAG on this board supports tracing ?
[21:12:11] <ds2> No, you cannot use this board
[21:12:15] <ds2> the ETM signals are not exposed
[21:12:27] <trace_guy> via OMAP ?
[21:12:38] <trace_guy> or JTAG ?
[21:12:43] <ds2> not all signals from the OMAP are exposed
[21:12:59] <trace_guy> can you mod the board to expose them ?

[21:13:46] <trace_guy> what is cost of doing this mod ?
[21:14:08] <Spyro> *cries*
[21:14:09] <ds2> keesj: don't think so
[21:14:25] <Spyro> but when I asked before here I was told that you COULD drive an LVDS panel ;(
[21:14:35] <ds2> you could, w/the right board
[21:14:39] <keesj> trace_guy: I don't know how you did it but your typing red and that is kind of ugly and anoying

[21:14:55] <ds2> LOOSE THE MIRC COLORS

[21:15:03] <trace_guy> sure
[21:15:06] <trace_guy> sorry again
[21:15:16] <ds2> Spyro: it seemed very obvious to me when it was said
[21:15:23] <ds2> trace_guy: thank you.
[21:15:31] <trace_guy> :)
[21:15:46] <Spyro> ds2: well Im pretty sure first time I asked I wasnt told 'with another board that doesnt exist'
[21:16:13] <Spyro> I bought the bb on the strength of being told it can speak LVDS :(
[21:16:17] <trace_guy> ok, but this board so cheap, pitty does not have it
[21:16:19] <ds2> Spyro: got a quote? IRC is logged and the mailing list is archived
[21:16:33] <ds2> trace_guy: have you seen the price of the ETM tools?

[21:17:02] <trace_guy> couple of grand I suppse

[22:47:07] <emeb> Need to get hub hooked up, get USB keyboard (old Mac kbd in garage) and try out the Trendnet ether dongle.
[22:47:34] <emeb> Funny - the beagle is smaller than all the accessories needed.
[22:47:47] <mib_cqvllx> emeb: synergy allows using one keyboard and mouse on workstation and beagle but reguires two monitors or extra input like you mention but is better with two monitors and easier I am certain.
[22:48:05] <emeb> Damn - this thing reboots fast!
[22:48:37] <mib_cqvllx> Well the kernel is just over 100kBytes

[22:49:52] <Spyro> ye gods...
[22:50:06] <Spyro> Im going to need to solder a 80 piin BGA to get LVDSS out of this thing!
[22:50:11] <mib_cqvllx> oops 100Mbytes
[22:50:33] <rektide> its scares me how much hardware dominates this channel
[22:50:40] <mib_cqvllx> It only has space tor two 20's
[22:50:42] <emeb> Sypro: why BGA?
[22:50:46] <rektide> its a frightening indicator of where i fear people spend all their time
[22:51:02] <Spyro> because TI only make BGA versions of that chip :/
[22:51:02] <emeb> Beagle is hardware!
[22:51:14] <emeb> Spyro: which chip?
[22:51:27] <Spyro> sn65lvds301

[22:54:36] <emeb> Feels good to finally de-lurk with actual hardware on the desk though.
[22:54:49] <emeb> paid the cover charge as it were...
[22:54:56] <Spyro> emeb: yeah
[22:55:02] <mib_cqvllx> yep, I have had my RevC2.2 for going on two weeks now.

[22:59:07] <mib_cqvllx> I have a big old Luxo lamp/magnifier I have to use anymore.
[22:59:25] <Spyro> BB + my DVI TV == FAIL

[23:03:34] <emeb> where do you get connectors for those?
[23:03:38] <Spyro> emeb: no idea

[23:03:45] <Spyro> emeb: digikey have some

[23:04:05] <Spyro> emeb: I guess I will use those now that I know I cant interface directly to bb
[23:04:18] <mib_cqvllx> 1.8vDC
[23:04:29] <emeb> I've got an LCD iMac in the garage with a dead mobo. Wonder if the BB can drive that LCD?
[23:05:25] <emeb> Spyro: Have you considered an FPGA? Xilinx Spartan3* can do 1.8V to LVDS
[23:05:25] <Spyro> emeb: who knows... I _have_ to drive this LCD - its the only one Icould find that actually fits in the hole
[23:05:44] <Spyro> emeb: I have no facility to program an FPGA
[23:05:52] <Spyro> emeb: but a CPLD might be possible.
[23:06:16] <Spyro> Id like this to not actually cost the earth too
[23:06:21] <emeb> Spyro: FPGA is easy - design tools are free and BB can download program into FPGA at boot.
[23:06:34] <emeb> I've done it with ARM7 processors
[23:06:57] <emeb> total $$ = 0

[23:08:46] <Spyro> emeb: interesting but probably more work than the TI chip (more pins and the TI chip requires no extra programming...
[23:08:52] <Spyro> )
[23:09:05] <emeb> There's that. But - no BGAs required.
[23:09:27] <emeb> And you can put tricky logic into FPGA for extra features if desired.

[23:12:51] <emeb> mib_cqvllx: 1206 is 2x 603. I mostly use 0804 for resistors & tantalum caps. 0603 for decoupling caps.
[23:13:16] <emeb> Spyro: devil you know.
[23:13:25] <Spyro> emeb: indeed

[23:14:14] <mib_cqvllx> emeb: I had a blown fuse in a LCD monitor I fixed. the 0603 was about half the size of what I needed. It was large enough to meet the solder points ans I used it.
[23:14:14] <Spyro> heh

[23:15:16] <emeb> mib_cqvllx: You can often get an 0603 part onto an 0804 footprint (or vice-versa). Never tried 0603 on 1206 though
[23:15:42] <mib_cqvllx> emeb: I was able to piggyback the fuse on the original.
[23:16:11] <mib_cqvllx> its length was just enough to meet the tinned part of the 1203 fuse.
[23:16:17] <emeb> That works too.
[23:16:43] <emeb> Here's a board I'm working on now - mostly 0804 & 0603: http://members.cox.net/ebrombaugh1/synth/armfpga/pix.html

[23:29:38] <Spyro> was quite fun :)
[23:29:49] <emeb> I'll bet.
[23:30:04] <Spyro> wish I made the casing about 3mm deeper, would have saved me a world of pain
[23:30:19] <emeb> Rev B!
[23:30:25] <Spyro> ??
[23:30:40] <emeb> (for the next time you do it)
[23:30:45] <Spyro> says C2 on the PCB
[23:30:59] <Spyro> oh right :)
[23:31:02] <emeb> Didn't mean the BB - meant revised dash.
[23:31:08] <Spyro> hehe
[23:31:25] <Spyro> nah will just compenasate for it by making the back case a couple mm deeper
[23:31:43] <emeb> So did you rip out the std instrument cluster?
[23:31:55] <emeb> (is car drivable without?)
[23:32:00] <Spyro> not doing it again just for that - took too much effort to make the bezel nice this time round (I got it razor sharp round the opening)
[23:32:11] <Spyro> I only trial fitted it so far
[23:32:19] <Spyro> the stock cluster is back in place for now
[23:32:34] <emeb> OK - reversible modification.
[23:32:42] <Spyro> As soon as I get road speed in there Im gonna run the beagle :)
[23:33:01] <emeb> That'll make it easier if you ever want to sell the car. :)
[23:33:10] <Spyro> yeah - I am filching the connector from my donor dash cluster so it will plug into the stock witing harness
[23:33:36] <Spyro> if I sell it I'll sell it with the dash - it wont fit the next car and it'll probably double the value of the car :-)
[23:34:04] <Spyro> I'll just build another one (custom fabbed fibreglass again)
[23:34:15] <Spyro> but this time the software will already be 90% done :)
[23:34:25] <Spyro> anyhow I dont plan to sell the car
[23:35:14] <Spyro> I just fitted AP coilovers all round and have scavenged a Mk3 GTI ABS system (all electronics, pump, brakes, discs, axles, wishbones, read suspension, driveshafts)
[23:35:30] <Spyro> so will have big brakes and ABS once thats all fitted
[23:36:11] <Spyro> (will be cleaning, shot peening, lacquering, fitting poly bushings, and generally doing it properly. might use porsche calipers and even bigger discs :-)
[23:36:12] <emeb> Wow - serious mods. You in UK?
[23:36:16] <Spyro> yep
[23:36:25] * fulgas is now known as FuL|OUT
[23:36:33] <Spyro> GTI performance on a TDI that does 69MPG ;-)
[23:36:36] <emeb> What's the legal aspect of driving a heavily modded car on the public roads?
[23:36:49] <Spyro> emeb: no Idea - I plan to keep stum :)
[23:37:30] <Spyro> when its all complete I might see if I can get my insurance altered to reflect the addition of the ABS
[23:37:42] <Spyro> adding ABS has got tobe one rare mod though
[23:37:56] <Spyro> and its massively involved if you are going to do it safely.
[23:38:10] <emeb> :) As long as they don't raise your rates for being too 'adventurous' :)
[23:38:29] <Spyro> hehe. Im not gonna point out the fact that the dash cluster can do GPS ;-)
[23:38:47] <emeb> Ack - someone's hacked my car!
[23:39:02] <Spyro> damn, knew that wifi was a security risk...
[23:39:09] <Spyro> I'll reinstall the cluster, honest :)
[23:39:53] <Spyro> the LVDS chip is quite configurable - selectable 1, 2, or 3 channel, with clock too
[23:40:07] <Spyro> its perfect... too perfect...
[23:40:27] <emeb> Just grabbed the datasheet. Need to look at it.
[23:40:51] <Spyro> you watch, my panel will want the RGB bits in the order 1, 4, 2, 3, 7, 6, 5, 0 or something silly, just to be awkward ;-)
[23:41:22] <Spyro> and in a different order depending on if the scanline is odd, even, or a prime number on a tuesday (except leapyears)
[23:41:24] <emeb> Should be fun doing an interface board - esp w/ BGA. They can be done DIY with a bit of care & planning
[23:41:57] <Spyro> Im planning to glue the chip upside down to a PCB and attach fine copper wire between it and pcb pads.
[23:42:04] <emeb> Maybe - you might be able to get around odd bit orders by munging the data in video RAM.
