| infinity | ogra_: A bit shocked that those drivers don't both ship in the same tarball (or even just as the same driver), but whatever. nvidia never ceases to confuse. | 02:25 |
| lilstevie | infinity, heh that is nvidia for you, I'm not even quite sure what the difference between the T2 and T3 pack is yet | 03:09 |

| marvin24 | lilstevie: the avp firmware is different, but that's also a different tarball ... | 07:38 |
| lilstevie | marvin24, yeah I know the avp firmware is, but that is cause the avp is different in general from what we have seen | 07:44 |
| lilstevie | marvin24, but the acceleration xorg driver and libs that you guys package up for the ac100 work just fine on the tf201 | 07:45 |
| marvin24 | lilstevie: the original tar gz (for up to abi 12) contains a lot more | 08:22 |
| marvin24 | e.g. kernel, bootloader, ... | 08:22 |
| marvin24 | abi13 driver was released as a single tegra_drv.so (which is identical for tegra2/3) | 08:22 |
| lilstevie | marvin24, oh yeah, bootloader and stuff could easily go in the same tarball though | 08:45 |
| lilstevie | given size is not big | 08:45 |

| marvin24 | maybe customers may get confused if they see more than one kernel ;-) | 09:20 |
| lilstevie | maybe | 09:44 |
| lilstevie | although that would be a little troubling :p | 09:44 |

| wookey | infinity: my build is failing with ../sysdeps/unix/sysv/linux/init-first.c:102:1: sorry, unimplemented: function profiling | 13:28 |
| wookey | and indeed it is unimplemented. Where do I turn it off for the arm64 build? | 13:28 |
| wookey | (eglibc) | 13:29 |
| wookey | aha debian/sysdeps/arm64.mk looks plausible. --disable-profile | 13:33 |
| doko | ogra_, is the openscenegraph ftbfs on arm the gl/gles problem? | 14:29 |
| ogra_ | dunno, i didnt even know it ftbfs | 14:29 |
| doko | asking because a whole lot of things b-d on it | 14:29 |
| ogra_ | (/me is on a special forces project until UDS ... so i didnt follow the ftbfs list) | 14:30 |
| janimo | marvin24, what's the prospect of ac100 being all mainlined, any ETA? | 15:15 |
| janimo | any blockers still? | 15:15 |
| * janimo hopes it's there by 13.04 :) | 15:15 | |
| marvin24 | janimo: it is (all) mainlined for over a year now | 15:15 |
| marvin24 | unfortunately, tegra2 support isn't ... | 15:15 |
| marvin24 | I would also prefer to move to mainline for 13.04 | 15:16 |
| marvin24 | we already lost supend with 3.1, so it shouldn't matter if we lose some more stuff ;-) | 15:16 |
| janimo | marvin24, well I mean ac100 support as in working out of the box :) | 15:17 |
| janimo | and your insight on where the tegra2 upstreaming stands | 15:17 |
| * ogra_ doesnt think there is anything gfoing on wrt upstreaming the tegra2/3 bits | 15:18 | |
| ogra_ | especially in the light that they are mostly developed for android which uses snapshot kernels | 15:19 |
| ogra_ | as long as android moves with that practice i doubt we'll see changes here | 15:20 |
| marvin24 | janimo: it works out of the box if you add the drm driver | 15:20 |
| marvin24 | ogra_: wrong, e.g. today lp2 support was added for tegra3 | 15:21 |
| ogra_ | ah, nice | 15:21 |
| marvin24 | I think tegra2 has it already | 15:21 |
| janimo | what's lp2 | 15:21 |
| ogra_ | well, they still build their binary drivers against a special kernel tag usually | 15:21 |
| marvin24 | but I haven't looked lately | 15:21 |
| ogra_ | and i doubt that will change in the short term | 15:22 |
| ogra_ | marvin24, janimo's dream is to use mainline for ac100 (and other tegras) in 13.04 | 15:22 |
| marvin24 | ogra_: tegra drm will likely come to staging in 3.8 | 15:22 |
| ogra_ | when is 3.8 due ? | 15:23 |
| marvin24 | and "they" already made some changes to mainline to get their propietary driver working | 15:23 |
| janimo | 6 mo probably | 15:23 |
| ogra_ | early 20013 ? | 15:23 |
| ogra_ | oops | 15:23 |
| marvin24 | no, we are not that slow | 15:23 |
| ogra_ | didnt mean to exaggerate that much :) | 15:23 |
| marvin24 | ;-) | 15:23 |
| marvin24 | so we will endup in a situation where both drivers are supported | 15:24 |
| marvin24 | the open one likely without any 3d or video accel | 15:24 |
| ogra_ | thats fine | 15:24 |
| ogra_ | and thats how i use the closed one atm :) | 15:24 |
| marvin24 | I hope I didn't look too deep into the glass | 15:24 |
| ogra_ | on my ac100 at least | 15:25 |
| lilstevie | yeah, O cam | 15:26 |
| lilstevie | er | 15:26 |
| lilstevie | I can't say I use the 3D and video accel on my prime either | 15:27 |
| ogra_ | well, and what for :) | 15:29 |
| ogra_ | there isnt really much thats built for GLES | 15:29 |

| ppisati | ogra_: by any chance, did you try Q on your beagle? | 16:05 |
| ogra_ | nope | 16:05 |
| ppisati | ok | 16:05 |
| ppisati | anyway, problem found and fix too | 16:06 |
| ppisati | i'll send a pull req tonight | 16:06 |
| ppisati | (after gym) | 16:06 |
| ogra_ | ppisati, you rock ! | 16:06 |
| ogra_ | will test with the fix then | 16:06 |

| sakoman_ | was the CONFIG_HIMEM issue on Pandaboard ever resolved? | 21:02 |
| sakoman_ | (i.e. random crashes when trying to do a kernel build if CONFIG_HIMEM was set) | 21:03 |
| ogra_ | ogra@panda:~$ grep HIGHMEM /boot/config-3.5.0-211-omap4 | 21:04 |
| ogra_ | # CONFIG_DEBUG_HIGHMEM is not set | 21:04 |
| ogra_ | CONFIG_HIGHMEM=y | 21:04 |
| ogra_ | we have it enabled since a while, so yes | 21:05 |
| ogra_ | at least in 12.04 and 12.10 it should be fine | 21:05 |
| sakoman_ | do you recall what the issue root cause was? | 21:05 |
| ogra_ | no, but there was a bug | 21:05 |
| sakoman_ | I'm working on another OMAP4 based system and it too has random crashes if HIMEM is enabled :-( | 21:05 |
| sakoman_ | running 3.6 | 21:06 |
| ogra_ | bug 633227 | 21:06 |
| ubot2 | Launchpad bug 633227 in linux-ti-omap4 "instabilities with highmem activated" [High,Fix released] https://launchpad.net/bugs/633227 | 21:06 |
| ogra_ | we use 3.5 in 12.10, seems pretty solid | 21:06 |
| ogra_ | but we dont use mainline. mind you | 21:07 |
| sakoman_ | hmmm . . . not really clear from that bug exactly what fixed the problem :-( | 21:10 |
| GrueMaster | What ever became of devicetree for arm? I'm reading articles covering the 3.7 kernel, and they don't even seem the same. | 21:17 |
| rsalveti | sakoman_: I don't think we got to the point of finding exactly what was the patch that fixed the issue | 21:57 |
| rsalveti | I believe that at some point it just worked as expected | 21:57 |
| tinti | Hi, can someone give me a hint about how to debug linux kernel boot without JTAG? I was thinking in use early_printk and try to use usb debug | 21:58 |
| === Ursinha_ is now known as Ursinha | ||
| === rsalveti_ is now known as rsalveti | ||
| wookey | tinti: DEBUG_LL is useful in early linux boot | 23:58 |
| tinti | wookey: thanks :) | 23:58 |
| wookey | maybe that's what's called early_printk these days | 23:58 |
| wookey | it writes direct to serial port | 23:58 |
| wookey | or probably USB these days, as no-one has serial ports anymore | 23:59 |
