  • [02:05:48] <mru> sgx is 3d graphics, not video
  • [02:06:00] <JDuke128> well but its dsp too
  • [02:06:29] <JDuke128> we can make player that will utilize sgx unit for faster playing ?

  • [02:07:45] <mru> it's a 3d accelerator
  • [02:08:08] <mru> maybe it could in theory be reprogrammed to decode video
  • [02:08:17] <mru> but we'll never have the necessary documentation
  • [02:08:30] <JDuke128> so , if i draw any opengl es application doesnt slow down my video play speed much
  • [02:08:33] <AlTheKiller> Mmm decoding in glsl
  • [02:08:37] <AlTheKiller> That sounds painful
  • [02:08:58] <JDuke128> omap supports GLSL and OpenCL ?
  • [02:09:04] <mru> everything shares the same memory bus
  • [02:09:13] <AlTheKiller> It supports gles2
  • [02:09:25] <mru> so anything using memory will slow down memory accesses for other parts
  • [02:09:39] <AlTheKiller> Open CL is a gpgpu interface
  • [02:09:42] <JDuke128> so memory is bottleneck between video and gpu
  • [02:09:46] <AlTheKiller> There's no gpgpu on the sgx
  • [02:10:15] <JDuke128> waow
  • [02:10:22] <JDuke128> we can add extra memory ?
  • [02:10:41] <AlTheKiller> Someone needs to got read elinux wiki
  • [02:10:47] <JDuke128> :)
  • [02:11:21] <JDuke128> i think opencv suck on beagleboard as i read some blogs
  • [02:11:42] <JDuke128> is there any native alternative for beagleboard for high performance
  • [02:11:42] <djlewis> now he's getting it.
  • [02:12:14] <raster> JDuke128: there is no "memory bottleneck" as such
  • [02:12:15] <AlTheKiller> I don't think there's any alternative, period.
  • [02:12:18] <raster> gpu uses same memory cpu does
  • [02:12:30] <raster> they share memory ala the integrated video on x86 desktops
  • [02:12:39] <raster> the gpu has its own internal caching layers
  • [02:12:44] <raster> like the cpu does (l2, l1 etc.)
  • [02:12:56] <JDuke128> nice
  • [02:13:07] <raster> if you want to get the gpu to do things for you - u'll need to use opengl-es (2.0 if u want shaders)
  • [02:13:15] <raster> and if u want to do "processing" - do it via shaders.
  • [02:13:29] <raster> as with all things - a resource is a resource. if you use it - there is less of it to go around for other tasks
  • [02:14:12] <JDuke128> i c
  • [02:16:01] <JDuke128> so if i use gpu L caches with gpu , that doesnt effect other units
  • [02:16:02] <JDuke128> well
  • [02:17:46] <JDuke128> when i play any video with omapfbplay on console , it doesnt go back console when video finishes and i cant control console back ?

  • [09:52:36] <aholler> ah, ok, that explains the errors I'm getting when reading mtd0 (xloader) from within linux.
  • [09:53:10] <av500> aholler: there uses to be confusion between uboot and kernel on which ecc scheme to use
  • [09:53:22] <av500> dunno if that is fixed
  • [09:53:26] <aholler> is there any special reason xloader is stored using hw-ecc? is this needed for the pre-xloader-bootcode?
  • [09:54:10] <av500> aholler: the sw ecc can be the same one as the hw one
  • [09:54:43] <av500> i forgot what the ecc issue was, koen?
  • [09:55:24] <aholler> av500: I had that with at91 too, but the at91-nand-driver now supports hw-ecc which is fine. So I've looked if i could find an option to use hw-ecc with the omap-nand-driver but nobody seems to has implemented this (which should be faster too).
  • [09:55:59] <av500> aholler: could it be that omap only supports SLC, but this NAND needs MLC?
  • [09:56:57] <aholler> i could read mtd1 without errors, only mtd0 fails. looking at the initial-flash stuff from verification, i see that xloader is stored with hw-ecc and u-boot with sw-ecc

However when I boot from SD card using angstrom distro I see the following sequence. I see the pic of beagle appearing on my LCD display followed by the booti

  • [20:57:12] <koen> a kconfig option
  • [20:57:29] <koen> you want the dsi pll to be enabled to get better clock dividers
  • [20:57:31] <prpplague> koen: ahh do tell
  • [20:57:39] <prpplague> ahh ok
  • [20:58:00] <koen> CONFIG_OMAP2_DSS_DSI=y
  • [20:58:01] <koen> CONFIG_OMAP2_DSS_USE_DSI_PLL=y
  • [20:58:34] <koen> sakoman: see above :)
  • [20:58:49] <prpplague> koen: and then use just a generic panel?
  • [20:58:54] <_av500_> yes, dsi pll
  • [20:58:54] <koen> yes
  • [20:58:56] <josh> is USB_SUSPEND still broken?
  • [20:59:11] <koen> prpplague: dsi pll gives you better pixclock option
  • [20:59:25] <_av500_> josh: did somebody come to you and solder you a new omap3?
  • [20:59:53] <koen> prpplague: do I detect a wvga lcd on your desk?
  • [21:00:12] <_av500_> wvga is so 2008
  • [21:00:16] <prpplague> koen: i have one, but not what i am working on
  • [21:01:12] <josh> nope, im on a custom design and im find that when i unplug a USB hub with USB_SUSPEND enabled it never wakes back up, after doing some googling i found the OMAP3 errata on the issue, was wondering if there was a main line patch for it
  • [21:01:30] <prpplague> koen: we are still having supply issues on the lcd
  • [21:01:46] <prpplague> koen: i wish we could find one with a better lead time
  • [21:01:54] <_av500_> josh: afaik, there is no workaround
  • [21:02:04] <_av500_> what does the errata say?
  • [21:02:12] <koen> prpplague: I get the impression china and the philipines took a 3 month holiday
  • [21:02:24] <prpplague> koen: yea
  • [21:02:33] <prpplague> koen: but lcd's are alway long leads
  • [21:02:37] <josh> the errata proposes a couple of work arounds but im not familiar enough with EHCI protocol to understand them
  • [21:03:15] <prpplague> koen: we have a couple of companies that are considering doing a PO for some ShowDogs, if we get some of those we'll move forward on making them available
  • [21:08:42] <koen> PO?
  • [21:08:56] <_av500_> purchase order
  • [21:08:59] <Crofton|road> purchase order
  • [21:09:43] <koen> ah
  • [21:09:54] * koen writes that down next to 'sku'
  • [21:10:18] <Crofton|road> what is sku?
  • [21:10:24] <_av500_> stoc keepin unit
  • [21:10:27] <Crofton|road> I think I know what it is
  • [21:10:30] <Crofton|road> ah
  • [21:10:44] <_av500_> koen: ecr?
  • [21:10:46] <Crofton|road> I new it was something alog those ilnes, figured it was latin
  • [21:10:50] <Crofton|road> heh
  • [21:14:31] <koen> Efficient Consumer Response?
  • [21:15:31] <_av500_> lol
  • [21:15:48] <koen> Crofton|road: latin doens't have a 'k', it's more a celtic or greek thing
  • [21:16:42] * koen educated his coworkers today on 'errata' being plural and 'erratum' being singular
  • [21:17:12] <_av500_> koen: singular does not happen very often with ti :)
  • [21:17:19] <koen> right
  • [21:17:33] <koen> and 430973 also applies to r1p3
  • [21:18:05] <koen> and no, uboot doesn't have a workaround for it AFAICS

  • [21:27:33] <_av500_> i read it as no fix at all
  • [21:28:19] <_av500_> the errata itself says "no workaround"...

  • [21:29:57] <josh> which errata are you looking at, i might have the wrong one
  • [21:30:16] <ssvb> koen: also what about a related erratum 687067 (which becomes a potential troublemaker when 430973 is workarounded) ?

  • [21:34:24] <ssvb> mru: a random question about xm memory corruption, has anybody checked whether erratum 468413 could or could not be involved?
  • [21:35:04] <josh> av500, nvm, i see Advisory 3.1.1.193 now, i was looking at 3.1.1.155, im using a USB3318, not USB3320, but im betting they are close enough that they have the same problem
  • [21:35:28] <_av500_> josh: yes, i guess so
  • [21:35:37] <ssvb> mru: do you see a corruption if L2 is disabled completely?
  • [21:35:51] <josh> thanks for your help
  • [21:36:18] <mru> ssvb: didn't think of trying that
  • [21:36:20] <BeaglePoop> Anyone have have any idea why my cshrc file will not run?
  • [21:37:17] <_av500_> josh: i would guess that 193 will mask 155 anyway
  • [21:37:42] <mru> ssvb: can't be 468413
  • [21:37:48] <mru> the L2 is set to outer
  • [21:38:25] <_av500_> ssvb: afaik, thew mem issue is in 512 and not on 256mb
  • [21:38:43] <josh> i would think so, im checking the data sheets on 3320 and 3318 to see what the differences are, if they have the same USBDIR delay then its moot
  • [21:38:48] <mru> that's the case, clocks are probably involved
  • [21:40:14] <_av500_> tried slower mem speed?
  • [21:40:55] <_av500_> josh: its not like it is the phy fault, so smsc had little reason to change that delay
  • [21:41:49] <josh> yah, just need to convince my boss that the erratta still applies to 3318 :-)
  • [21:41:55] <_av500_> josh: do you depend on suspend?
  • [21:42:16] <_av500_> usb suspend
  • [21:42:25] <josh> dont think so, but its a device that runs on battery so power savings are key
  • [21:42:41] <_av500_> what do you have on usb?
  • [21:43:10] <josh> in the "field" nothing, but eng/dev uses it for debug with a usb-ethernet dongle
  • [21:43:53] <josh> im just going to disable USB_SUSPEND, when it goes to production we can turn it back on if they want
  • [21:44:07] <josh> how much juice can it save anyways?
  • [21:44:24] <_av500_> no idea

  • [21:47:32] <_av500_> enjoy
  • [21:49:56] <josh> actually, while i got ya ;-) if a usb-ethernet dongle is yanked, is there an easy way to do an ifconfig eth0 up when its reconnected? Was thinking i would have to use mdev
  • [21:50:20] <_av500_> err, no idea
  • [21:50:54] <_av500_> doesn some kind of network manager do such things?
  • [21:51:30] <josh> this is embedded land, just have busy box and a few utils, i would hate to have to use a polling bash script
  • [21:51:54] <_av500_> josh: how is it setup the 1st time?
  • [21:52:07] <josh> .profile runs udhcpc
  • [21:52:16] <_av500_> ah
  • [21:53:04] <josh> im pretty sure udev can do it, i think mdev might be a little too light weight
  • [21:53:18] <aholler> mdev is right way
  • [21:54:01] <josh> can mdev pick up on a network device?
  • [21:54:48] <josh> i saw this in the primer (tun|tap) root:network 660 >net/%1 , honestly not sure what (tun|tap) is
  • [21:54:50] <aholler> why not, it just gets the device names, so I assume you just have to add a config-line for usb[0-9]
  • [21:55:30] <josh> how would i know usb[0-9] is a network device as opposed to a thumb drive?

  • [21:55:40] <aholler> for usb-storage im using this: sd[a-z][0-9]* root:disk 0660 */lib/mdev/sd
  • [21:56:17] <josh> ive done the same thing for storage, this is really a eth0 device
  • [21:56:48] <aholler> don't know if anything other uses usb[0-9] as device name. But I assume you could fiddle with /sys/somewhere to check the type of the device
  • [21:57:17] <aholler> anyway, ifconfig will fail if it gets a wrong device, so you could use * as device name ;)
  • [21:58:10] <josh> and im sure ill get smacked in the back of the head if someone catches me doing that :-)
  • [21:58:29] <aholler> maybe ifplugd is an option
  • [21:59:43] <josh> hmm, ill look into that, seems like it might work
