01:01 <mrfixit2001> anarsoul that's a good thought. I know that LibreElec has always used 64-bit kernel with 32-bit userspace. And they are wanting to use panfrost as well for rk3399 builds. Honestly, I was pleasantly surprised with the number of things that ran well. I ended up being able to get n64 running decently as long as it was the libretro core, I would say

01:01 <mrfixit2001> approximately the same performance as I'm getting on the mali blob at this time.

01:01 <mrfixit2001> even low resolution video file playback rendered well.

01:03 <mrfixit2001> and the dreamcast libretro core (flycast) also ran really well, about on par. A few graphical glitches still, as to be expected, but really was impressed. Not ready to be used in a release yet, but I'll be testing again in a few months to check the progress for sure!

01:07 <mrfixit2001> Rounding back around to test lima again now that I've got all the build flags right and have a baseline for panfrost

03:45 <wens> getting timeouts w/ panfrost on next-20191011 and mesa HEAD @ 075a96aa926, just starting X11 w/ modeset & glamor, on veyron-speedy (rk3288)

07:42 <urjaman> wens: how many/often timeouts? anyways "singular" page fault + a timeout (TRANSLATION_FAULT_LEVEL2 or 3 usually) is known about already

07:43 <urjaman> i can trigger it pretty reliably by switching youtube to/from fullscreen in firefox (with firefox forced to use OpenGL compositing)

08:37 <wens> about once every second

08:49 <urjaman> what are you running in your X11? (or nothing at all?)

08:51 <wens> lightdm

08:51 <wens> It hasn't gotten past the login part

08:52 <wens> dropping back to an older kernel made things work again

08:52 <rcf> Which kernel?

08:52 <urjaman> okay so it's something new

08:52 <rcf> I'm rebuilding to latest git HEAD, so might as well be sure the kernel is right in testing this.

08:53 <wens> 5.3.0-rc5-next-20190821, kind of old

08:53 <wens> I guess I should try v5.3.x proper first

08:53 <urjaman> i have a working kernel based on 5.4-rc2 (atleast with XFCE, i dont have lightdm but i assume it's not to blame)

08:56 <rcf> If it works, I'll see if I can break it with the -rc kernel

09:10 <wens> hmm, 5.4-rc2 doesn't work

09:13 <rcf> 5.3.1 works.

09:14 <rcf> Took its time trying to start, but I did get lightdm to show up.

09:22 <rcf> wens: can you get it to work on 5.3 proper?

09:29 <wens> v5.3.0 works

09:36 <rcf> I suppose that means you could have fun bisecting the regression yourself, or just complain upstream.

14:49 <urjaman> this is odd ... if you try to run anything via llvmpipe (eg. "LIBGL_ALWAYS_SOFTWARE=1 glxgears") while panfrost is running glamor you get some LLVM error messages and a segfault

15:02 <alyssa> mrfixit2001: Nice! (re 32-bit userspace)

15:02 <alyssa> "DRM_IOCTL_PANFROST_CREATE_BO failed: Cannot allocate memory" just sounds like you're out of memory?

15:04 <alyssa> urjaman: wontfix ;P

15:05 <urjaman> alyssa: fix dosbox and kicad then :P

15:07 <urjaman> but yeah this llvmpipe thing seems like some soft of a misconfiguration that even I could maybe fix

15:10 <urjaman> in other news, Ultimaker Cura runs but is very laggy due to lots of faults & timeouts

15:16 <alyssa> Bwap.

15:24 <alyssa> I'm starting to look at prep for OpenCL

15:24 <alyssa> Happy Thanksgiving everyon' :)

15:27 <alyssa> First step will be fixing regressions on current compute stuff

15:28 <alyssa> After that, I need to do some design on how we want bit sizes to work

15:45 <alyssa> # apt install spirv-tools llvm-spirv libllvmspirvlib-dev

15:45 <alyssa> $ meson configure -Dopencl-spirv=true -Dgallium-opencl=standalone

15:46 <alyssa> ^ something like that should build with opencl (just note to self)

16:07 <mrfixit2001> alyssa re "DRM_IOCTL_PANFROST_CREATE_BO failed: Cannot allocate memory" - doesn't happen on the mali blob, isn't running anything except the one emulator, and the card has 4gb of ram

16:07 <mrfixit2001> urjaman dosbox works :) I tested it and played wolfenstein 3D just fine

16:08 <mrfixit2001> ^-- using gbm/egl/gles without any windowing systems

16:09 <alyssa> mrfixit2001: panfrost uses more ram than necessary so.

16:09 <urjaman> mrfixit2001: yeah but using the opengl backend in Xorg

16:10 <urjaman> it has some wallpapering problem (you can only see what the thing updated)

16:10 <urjaman> i had a very glitchy moment of trying to play SimCity 2000 with it (and that's why i tried the llvmpipe since i dont really need the speed for that, using the opengl backend just for scaling)

16:14 <urjaman> having a 1366x768 screen is very awkward for playing VGA things :P

16:14 <mrfixit2001> There's definitely a scaling issue - I found that out trying 800x600 rendering. Make me want to "adjust my 1980's antenna because the reception was bad"

16:15 <alyssa> So, I'm trying to think if we can do RA .... bytewise, maybe?

16:15 <alyssa> Componentwise, at least .
