  100. [14:09:43] <alastor> Sorry guys for bothering, but I have an update on my digikey lead time status, which states "06/01/2011 Delivery Date Past Due" - what does it mean ???
  101. [14:10:20] <mru> nothing, it's digikey
  102. [14:12:25] <alastor> Well thanks again @mru - I can't wait when I get my board ...

  109. [14:41:02] <alastor> "Delivery Date Past Due" - can anyone translate it to me ? ( Google is as useless as always )
  110. [14:42:44] * sraue (~stephan@xbmc/staff/sraue) Quit (Ping timeout: 250 seconds)
  111. [14:43:01] <mru> it's digikey, it doesn't mean a thing
  112. [14:44:06] <alastor> well, if I google "past due", it gives me "late payment", that's why I ask
  113. [14:44:12] <alastor> it bothers me
  114. [14:48:01] <alastor> sorry, English is not native - otherwise I wouldn't ask
  115. [14:48:24] * eFfeM (~frans@j200125.upc-j.chello.nl) Quit (Quit: Leaving.)
  116. [14:51:55] <dm8tbr> my interpretation is: it should have been delivered already but isn't yet
  117. [14:54:42] <alastor> thanks @dm8tbr - but I didn't have a message stating that it even shipped yet - "your order hasn't shipped yet"
  118. [14:54:56] <dm8tbr> yes
  119. [14:55:25] <dm8tbr> let me word it differently: 'We didn't ship your pandaboard yet and we don't know why'
  120. [14:55:59] <alastor> well, that sounds confusing
  121. [14:56:17] <alastor> did you get your board, @dm8tbr ?
  122. [14:56:40] <dm8tbr> yes in, umm I think it was early november. PEAP round 1
  123. [14:56:58] <alastor> ok
  124. [14:57:31] <dm8tbr> it's not confusing if you know that digikey just receives boards in batches from the producing company and doesn't know in advance when that exactly will be
  125. [14:59:12] <alastor> now I get it better - I guess it is the same if you look on the lead time or not
  126. [15:00:49] <dm8tbr> as long as you have ordered you will eventually receive it
  127. [15:01:26] <dm8tbr> there are people who wait for digikey to mark the PB as 'available in stock' - that will likely not happen as they sell faster than they receive them
  128. [15:01:39] <alastor> I know it - it is not Pandora after all
  129. [15:02:00] <alastor> I have ordered on the 25th of November
  130. [15:03:11] <dm8tbr> they are shipping faster than pandora for sure :)
  131. [15:04:20] <alastor> thanks @dm8tbr for clarifying some staff - see ya

  155. [18:28:40] <topfs2> robclark: I tried a 02-triangle gles2.0 rendering in the SDK and it runs at 18fps aswell in 1680x1050, and thats just rendering ONE triangle without anything really significant shaderwise
  156. [18:28:50] <topfs2> So I'm pretty sure something isn't right, any idea how to debug?

  159. [18:42:44] <koen> topfs2: do you have acces to the debug version of the libs?
  160. [18:44:08] <topfs2> koen: does not look like it, I'm using ubuntu (https://launchpad.net/~tiomap-dev/+archive/release) looks like there is no -dbg
  161. [18:44:23] <koen> hmm
  162. [18:44:47] <koen> I guess you need to bother vstehle for the sdk then
  163. [18:44:59] <koen> that should have the debug versions of the libs you can hook into with a profiler
  164. [18:46:22] <topfs2> Its really weird because this feels like its way slower than beagle tbh
  165. [18:46:47] <topfs2> It seems to be extremely dependent on the resolution, 480p is in 120fps (which is probably what XBMC runs at at that res.)
  166. [18:48:20] <topfs2> hmm, when I think of it I could try the trunk (https://launchpad.net/~tiomap-dev/+archive/omap-trunk) might have it fixed

  171. [19:14:44] <kveroneau> Hello, I am thinking of purchasing a panda board, but am not a fan of Ubuntu. I prefer Debian Lenny or Squeeze.
  172. [19:15:15] <kveroneau> Is it possible to create a stage2 root image via debootstrap to use on the PandaBoard?
  173. [19:15:54] <kveroneau> Would most of the hardware still be accessible, or would I need to use the Ubuntu kernel and modules to enable full functionality?
  174. [19:17:06] <kveroneau> I currently have a SheevaPlug, which perfectly runs both Lenny and Squeeze which I bootstraped from my Debian desktop.
  175. [19:17:29] <topfs2> Ubuntu starts and much work without the extras, so if you patch the debian kernel I would be surprised if not the same where true for debian (note though that I
  176. [19:17:35] <topfs2> m not at all good on such stuff)
  177. [19:17:57] <topfs2> If you want sgx, bluetooth and wifi you need extras, not sure how those would fair on debian
  178. [19:18:18] <kveroneau> How are these installed and used on the Ubuntu?
  179. [19:18:25] <topfs2> https://launchpad.net/~tiomap-dev/+archive/release
  180. [19:18:40] <topfs2> so apt-get debs
  181. [19:18:52] <topfs2> not sure if they are compatible with debian or not
  182. [19:19:21] <kveroneau> Hmm, it may work. I have installed debs from Ubuntu on Debian before with little fuss.
  183. [19:19:44] <topfs2> I have not seen anyone running debian on panda yet though
  184. [19:20:16] <kveroneau> Well, if I'm the first one, I'll be sure to share a minimal installation image for those who are interested.
  185. [19:20:36] <kveroneau> Debian does have a full armel port, which I use on my SheevaPlug.
  186. [19:21:30] <kveroneau> I will most likely use the Ubuntu kernel and modules, to limit the hardware compatibility issues.

  188. [19:22:23] <kveroneau> Can the PandaBoard boot from a BOOTP/TFTP server?
  189. [19:23:01] <kveroneau> I suppose it has compatibility for u-boot, if so, it should support BOOTP with little problems.
  190. [19:24:13] <topfs2> If you use ubuntu kernel and those debs I would assume it would be possible

  207. [19:36:51] <kveroneau> My SheevaPlug runs Debian and it is an armel-based processor like the PandaBoard.

  211. [19:38:20] <kveroneau> ARM ports supported: http://www.debian.org/ports/arm/
  212. [19:38:23] <koen> so you miss out on all the new instructions since then
  213. [19:38:49] <koen> dude, I created the toolchain for the first armel port, don't go lecturing me on debian and arm
  214. [19:38:52] <kveroneau> I am using the kernel compiled by Marvell and their modules.
  215. [19:40:21] <kveroneau> I'm not using a Debian built kernel, just their package repos. The kernel built by Marvell for my SheevaPlug, is based on the Ubuntu kernel with the specific modifications for their hardware.
  216. [19:40:54] <koen> that still leaves you with a armv4t userspace
  217. [19:40:59] <kveroneau> I will be basically doing the same thing with the pandaboard, using the support Panda kernel image from the Ubuntu image provided on the Wiki with a Debian-based system and packages.
  218. [19:41:20] <koen> that still leaves you with a armv4t userspace
  219. [19:41:38] <kveroneau> Why hasn't this all been backported to Debian like everything else in Ubuntu?
  220. [19:41:48] <koen> so if you're only going to use armv4t, why not get an armv4t cpu?
  221. [19:41:51] <koen> much cheaper

  243. [20:20:52] <topfs2> one opaque triangle with fixed colour in 1680x1050 I see max 18fps, which surely must be to low
  244. [20:21:03] <topfs2> I can add quite a bit more to that and see no drop in fps

  260. [21:11:52] <topfs2> its using release ubuntu ppa.
  261. [21:12:06] <topfs2> Ill take a quick try at the flipchain fix, but last it just gave garbled output
  262. [21:12:13] <robclark> that doesn't mean that there isn't something wrong ;-)

  265. [21:12:57] <topfs2> I don't like ubuntu on embedded actually, would have liked to use angstrom but no X sgx love :S

  267. [21:14:42] * robclark recommends 24.11 kernel
  268. [21:15:18] <topfs2> Just need to find it, but yeah I could try that
  269. [21:15:24] <topfs2> should 24.11 work with the trunk ppa?
  270. [21:15:28] <robclark> I think nicolas posted to the ml list a little while back with a wiki page about how to update the latest stuff
  271. [21:15:52] <topfs2> would be awesome to just upgrade, I'll google
  272. [21:15:59] <robclark> I know there were power mgmt changes between 24.9 and 24.11.. my guess is trunk ppa is for 24.11
  273. [21:16:59] <topfs2> I found an article now, will see if this helps

  292. [22:37:02] <topfs2> thanks robclark seems like its alot faster now
  293. [22:37:17] <robclark> ahh, good!
  294. [22:37:27] <topfs2> not sure if its the 3x over 535 which is in the PR though :)
  295. [22:37:35] <topfs2> seems to be about the same as 535 tbh
  296. [22:38:03] <robclark> well, any comparisions to omap3 would be vs 530, not 535..
  297. [22:38:12] <topfs2> ah ok
  298. [22:38:16] <robclark> but I guess 540 should be faster than 535..
  299. [22:38:25] <robclark> but that doesn't mean there aren't any bugs standing in the way
  300. [22:38:55] <topfs2> Ill try and see if I can turn down the resolution and such and see if that helps
  301. [22:39:07] <topfs2> I also have the netbook ui in the background atm which might take a bit performance?
  302. [22:39:23] <topfs2> And I could probably take a look at the flipchain thing now also
  303. [22:39:44] <robclark> yeah, probably a good idea to try and re-enable it
  304. [22:40:04] <topfs2> Interestingly enough I started a video now and those shaders are quite heavy and the FPS did almost not budge
  305. [22:40:13] <topfs2> went from 24 to 21
  306. [22:41:10] <topfs2> So could be that the bottleneck is elsewhere. If it cant flip between the buffers (if thats what flipchain means?) that would take quite a tool on performance I would assume

  308. [22:41:38] <rys> SGX clock is 50% (ish) higher in 4430 vs fastest omap3s, as well as it being 540 vs 530
  309. [22:41:49] <robclark> yeah.. but I think the flipchain flipping should be at the vsync rate
  310. [22:41:56] <_troll_> topfs2: are you syncing to vblank anywhere?
  311. [22:42:08] <_troll_> that would quantise the possible frame rates somewhat

  314. [22:43:18] <robclark> (in case you'd noticed getting half expected fps on some recent kernels)
  315. [22:43:28] <topfs2> _troll_: this is what I can't figure out but it is likely. xrandr seems to report 0hz but the fps seems to always be rather perfect, which leads me to believe that its 20ish, 25ish, 30ish, 40ish 10ish 18ish
  316. [22:44:01] <topfs2> And currently I should have easily doubled processing but it only dropped 5fps (not a good messurement I know)
  317. [22:46:30] <topfs2> _troll_: you know any way to easily check this? or is this something I tell X when I create the window?
  318. [22:46:50] <topfs2> because we do lock at vsync on desktop when I think of it, let me try and see if it works to disable
  319. [22:46:51] <_troll_> it's a dss thing
  320. [22:46:55] <_troll_> poke around sysfs
  321. [22:47:01] <topfs2> ah ok, so its not normal xlib?
