got things working on T720, was a simple matter of flipping the right bits
<
tomeu>
no weston yet though
<
tomeu>
but enough for igt :)
<

narmstrong: do you know when the defconfig changes will make it to a tree that is built by kernelci?
<
tomeu>
guess we could have our panfrost-for-next branch, but it would be probably not a good use of kernelci resources

alyssa: do you happen to know how to force a GPU hang with SFBD?
<
shadeslayer[m]>
I can't think of anything else that needs fixing for now
<
tomeu>
shadeslayer[m]: you should be clearing up the commit story before asking others to review
<
tomeu>
otherwise it's more work, and you anyway need to do that
<
shadeslayer[m]>
Ok, should I just open a MR after?
<
tomeu>
shadeslayer[m]: well, I think alyssa is not using gitlab's web UI
<
shadeslayer[m]>
Aw :(
davidlt has quit [Ping timeout: 244 seconds]
<

shadeslayer[m]: you can just send them to mesa-dev like any other patches
<
shadeslayer[m]>
I need to figure out how to do that, never had to before :)

alyssa: we have a test in igt about gpu resets
<
alyssa>
narmstrong: I ask Kevin lots of things
<
alyssa>
tomeu: What I'll suggest is taking the ->format field
<
alyssa>
And just doing a loop of
<
tomeu>
oh, good idea
<
alyssa>
for (unsigned i = 0; i < 32; ++i) { fb->format ^= (1 << i); /* render */ }
<
alyssa>
Eventually you'll break something
<
tomeu>
alyssa: no luck
<
tomeu>
trying with clear_flags now
<
tomeu>
alyssa: I'm only getting DATA_INVALID_FAULTs
jernej__ has joined #panfrost
<

alyssa: Bingo! 608d
<
tomeu>
tomorrow will use the value to cause the hang
<

alyssa: you should consider switching to gitlab ui, it's convenient
jernej__ has quit [Quit: Konversation terminated!]
<
alyssa>
tomeu: It scares me that that works.
<
alyssa>
Just to be clear, setting random bits should
*not* cause hangs. But yuknow :P

Half of the tests in a section fail, half pass

I set a magic bit

Now the first half all pass, and the second half all fail

I'm rewriting pantrace stuff
<
alyssa>
Code is now waaaay simpler and waaaaaaaaaaaaaaaaaaaay faster
<
alyssa>
As in, fast enough to trace small scenes in real-time now
<
alyssa>
And on medium size scenes the bottleneck is just I/O / terminal rendering
<
alyssa>
(If I pipe the trace to /dev/shm/, it's real-time)
