<anarsoul> alyssa: I just ran q3a on panfrost :P
<anarsoul> opengl1 renderer works fine, opengl2 fails somewhere in nir validation

<alyssa> anarsoul: \o/
<alyssa> What's the NIR error?
<anarsoul> I'll send it later to you, currently working on grub package for archlinux
<anarsoul> and then bootstrapping archlinux onto PBP
<alyssa> Nice
<anarsoul> it's a week old mesa, so could be already fixed
<alyssa> I haven't landed much recently so

<alyssa> My hobby: SIMD on scalar architetcures with vectors over Z_2
<anarsoul> I thought midgard is vec4
fysa has joined #panfrost
<alyssa> anarsoul: The CPU is scalar
<alyssa> well I guess there's NEON but that's a rabbit hole I'm not prepared for yet.
<alyssa> Although, to be fair, I would totally NEONize the solver just for the inception.
fysa has quit [Ping timeout: 276 seconds]
<alyssa> test_linear() could probably be NEONized :p

<mifritscher> (00:56:55) enunes: I do losetup -f -P <image.raw> and them mount /dev/loopNpX -> kpartx can do this as well
<anarsoul> yeah, but losetup is in util-linux which is available in pretty much every distro
<anarsoul> e.g. kpartx is not packaged for archlinux, you'll have to install it from aur

* urjaman thought a bit ...
adjtm has joined #panfrost
<urjaman> https://urja.dev/pf191109.txt like for context there's a not so random sample of the kind of warning spew i get (with the bonus running of two warnings simultanenously)
<urjaman> so if that's the race of things being unmapped early ... i think it's not shared interrupts because on the RK3288, as far as i parsed /proc/interrupts right, the gpu doesnt share interrupts with anything
<urjaman> there are two other places that the kernel gives WARNINGs about for me, one is dma-fence.h:533 (as far as i parsed the backtrace correctly, when trying to cancel the "guilty" job)
<urjaman> and the another (quite rare) is from io-pgtable-arm.c:330
<urjaman> (that one is panfrost_ioctl_create_bo -> panfrost_gem_create_with_handle -> drm_gem_handle_create_tail -> panfrost_gem_open -> panfrost_mmu_map -> mmu_map_sg -> arm_lpae_map ...)
<urjaman> (also this highlights one thing: having the kernel spew warnings during 'normal operation' (well, quite laggy moment of a normal operation but still :P) makes it easy to miss other warnings in dmesg because there's always a backtrace there...)
