IRC log of #cubox of Wed 20 Nov 2013. All times are in CET < Back to index

01:22 _rmk_ yay, agreement reins on my point :)
09:56 jnettlet Interesting enough, galcore running under 3.0.35 kernel nice and fast no problems. galcore running under 3.10 kernel, almost 3 times slower.
09:56 jnettlet I have to see if some sort of scaling is not happening.
09:59 hste_ jnettlett: Do you use the latest vivante-libs?
10:00 jnettlet hste_, yep both kernels are using the same userspace
10:02 hste_ jnettlet: yocto master had some new libs that worked better on glmark2 than the dora version on my gk802 (imx6q)
10:03 hste_ but I have only used 3.0.35...
10:05 jnettlet this is definitely something to do with the kernel. The way freescale moves code between branches is a mess though so bisecting what caused it may be impossible.
14:37 jnettlet _rmk_, ping
14:56 _rmk_ hmm?
15:00 jnettlet if you have a couple of seconds I was wondering your opinion on a theory.
15:01 jnettlet I am tracking down this big performance slowdown between the fsl 3.0.34 and 3.10 kernels in regards to galcore.
15:02 jnettlet The main difference between the two kernels is galcore uses CMA with 3.10 and the old DMA_ZONE_CONFIG with 3.0.35
15:04 jnettlet obviously the memory is still allocated through the dma_alloc_ interfaces, but is there anything you can think of as to why the memory allocation method would affect performance?
15:08 _rmk_ is it the allocation which is slowing it down, or is it the use of the memory?
15:08 jnettlet the use of the memory.
15:09 jnettlet I am going through the driver diffs again more closely to see if I missed anything. But under CMA I am not even seeing some things flushed to the framebuffer properly.
15:10 _rmk_ nothing springs to mind
15:11 jnettlet okay I will keep digging.
15:20 hste_ When running glmark2 in xorg with 1080P the Screens goes black and X have to be restarted: mxc_ipu mxc_ipu: IPU Error - IPU_INT_STAT_10 = 0x0008000, at 720P it runs without problem
15:21 _rmk_ hste: black or loses sync?
15:22 hste_ goes black. No hdmi signal
15:22 hste_ I have seen someone had similar problems running xbmc
15:23 _rmk_ so both then, and not black _with_ sync.
15:25 _rmk_ the distinction is important, because it's the difference between the IPU still being alive but being fed black vs the IPU being dead
15:30 hste_ I found this older commit http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/commit/?h=imx_2.6.35_11.09.01&id=bc8159027063aded47316b669b1293998337b2ee
15:34 rabeeh hste_: those are ipu under runs
15:34 rabeeh same like xbmc
15:34 rabeeh i have a fix; checked it with geexbox team and needs some refinement
15:35 tazou hi rabeeh do you received my postal card ? :)
15:35 rabeeh tazou: hey
15:36 rabeeh hmm... no one from the team told me; so it's probably on the way :)
15:36 tazou h?h? ok
15:36 rabeeh thanks a lot for it; i'm anticipating when it will arrive
15:36 tazou with plesure ;)
21:07 jas-hacks_ rabeeh: On C1 is the 'cd' pin wired for the micro sd card?
21:43 jnettlet jas-hacks_, cd is wp isn't
21:43 jas-hacks_ no wp (write protect) , cd is card detect
21:45 jnettlet cd is wired, wp isn't
21:45 jas-hacks_ thxs
21:51 cyball hi @all ... I'm trying to boot my recently delivered board :-) .. are there some instructions how to get u-boot running ? thx :-)
21:51 jnettlet cyball, http://imx.solid-run.com/wiki/index.php?title=Building_Carrier-One_U-boot_and_Kernel
21:52 cyball thx
22:21 cyball can I boot the board with the msata connector?
22:22 cyball or do i need to put all the stuff on the microsd?
22:47 cyball ok there is no mSATA on my board :D
23:39 mhoney you mean eSata?
23:41 cyball mhoney, no i mean mSata there (http://imx.solid-run.com/wiki/index.php?title=Carrier-One_Hardware#Detailed_hardware_specification) should be 3 different ifaces on the back of the board but there is only the microSD slot :-)
23:46 mhoney Italic lines below are features not populated in the first batch for developers.
23:47 dv oh my
23:47 dv this is retarded
23:47 dv apparently, if source and destination of an IPU blit task are identical (except for the physical addresses of course), in other word, if I just want to do a 1:1 pixel copy, the ipu device sees this as an error
23:49 mhoney (insert a witty response here)
