alyssa changed the topic of #panfrost to: Panfrost - FLOSS Mali Midgard & Bifrost - Logs https://freenode.irclog.whitequark.org/panfrost - <daniels> avoiding X is a huge feature

<tomeu> narmstrong: have you seen this, btw? https://gitlab.freedesktop.org/mesa/mesa/-/jobs/830983
<tomeu> ah, seems to have been a server reboot

<narmstrong> :-(
<narmstrong> I’m asking, was not aware of a reboot
<paulk-leonov> alyssa: btw, just stumbled upon https://github.com/ARM-software/ComputeLibrary which seems to contain some midgard/bifrost bits, maybe that can be of interest to you :)

<alyssa> paulk-leonov: Think I've seen that before but let's see

<alyssa> paulk-leonov: I think it's just a regular OpenCL library that does some checks for GPU version to replace with special optimized CL kernels ... no interesting hardware details exposed afaict

<robmur01> urjaman: the T720 brokenness running super-slow turns out to be great for reliably reproducing the races I've occasionally seen
<robmur01> so I've actually managed to start debugging them :)
<alyssa> Tada!
<robmur01> ...and now that it doesn't kill the kernel, onwards to figuring out how everything manages to get freed before the GPU is completely stopped in the first place
<alyssa> Graphics liberation!
<urjaman> ;)
<robmur01> they're just a bit *too* liberated right now
<alyssa> That'd be my fault
tlwoerner has quit [Quit: Leaving]
<robmur01> I think shared interrupts may play a large part in it

<paulk-leonov> alyssa: right, had a closer look and it looks like it's an empty shell...
<paulk-leonov> sorry for the noise

<robmur01> paulk-leonov: yeah, it's basically just a bunch of optimised building-block primitives from the ML folks - https://www.arm.com/why-arm/technologies/compute-library
<alyssa> paulk-leonov: No worries
<robmur01> although I guess it could be mildly interesting in a shader-db context?

<alyssa> IN WHICH Alyssa tries to use Kevin I as a test farm for Kevin II
<alyssa> First things first, let's `tar cfz dEQP.tar.gz VK-GL-CTS/` so I get the test suite on Kevin I
<alyssa> Already built, ABI should be compat probably
<HdkR> But where is Kevin the third?
<alyssa> HdkR: Rock Pi's in the corner ...
<HdkR> lol
<alyssa> I'm trying to figure out the best way to do builds of Mesa itself
<alyssa> Options are....
<alyssa> 1) Push source to Kevin I (via git), do build on Kevin I
<alyssa> 2) Do build on Kevin II, push binary to Kevin I
<alyssa> 3) Do build on Kevin II and use an NFS or filesystem over USB type-C or something (is that even possible???)
<alyssa> 4) For completeness I guess source over USB type-c and build on kevin I lol
<alyssa> ...Turns out, mass storage gadget is a thing, lol
<alyssa> But I'm thinking #1 is the best option ... still need a connection between the Kevins but I can probably do something wild for that ...
<HdkR> I had a script setup that watched a git repo for changes and just rsync'd it remotely :P
<alyssa> Hmm
<HdkR> Using fswatch I think it was
<alyssa> USB type-c gadget seems like the "ideal" solution for this but I don't want to rebuild kernel for either kevin
<alyssa> Source of the network looks like the right way ... trying to figure out how to do that reliably
<alyssa> If one machine on wifi the other on ethernet etc..
* alyssa could tunnel she supposes but this seems strange
<alyssa> If anyone has a suggestion, I'm listenin'
<alyssa> In the mean time, back to swizzling'
* urjaman is confused as to the question
<alyssa> urjaman: I have two Kevin laptops side-by-side physically
Elpaulo has quit [Remote host closed the connection]
<alyssa> I'd like to `git push` from one to the other, so I can dedicate one to running test suites
<urjaman> OTOH all my "networks" (wlan or ethernet) are bridged together in the router
