<alyssa> "jenneron: to confirm, these..." <- i don't know how to answer this.. i just clone it from git and build with those flags
<jenneron[m]>
0001-big-hack.patch doesn't make t604 working on latest main
<alyssa>
nod, didn't think so
<alyssa>
what does "not working" mean in this case
ente` has joined #panfrost
<jenneron[m]>
alyssa: some parts in UI are being randomly replaced with just black color and these logs https://dpaste.com/G43MA42VT
<jenneron[m]>
same behavior as without patch
<alyssa>
jenneron[m]: what workload? everything?
<alyssa>
please run a simple application (and I do mean simple! kmscube or es2_tri are ideal, glxgears is fine, glmark2 -bbuild works too.)
<alyssa>
with the env var `PAN_MESA_DEBUG=sync,trace`
<alyssa>
that will *crash*
<alyssa>
but should writeout a bunch of files named pandecode.[number]
<alyssa>
please send the *last* one written
<alyssa>
(pandecode.17 or something)
<alyssa>
and also send the dmesg logs that are written from just that
<alyssa>
(just the end of dmesg basically)
<jenneron[m]>
alyssa: iirc when using glmark2-es2-drm it was fine, but i can't test it again because of cracked display
<jenneron[m]>
also, iirc glmark2 and mpv worked fine in xorg, only issue with UI (gnome, xfce4)
<jenneron[m]>
like everything except glmark2 window was in artifacts
<alyssa>
uh ok
<jenneron[m]>
alyssa: will try this
<jenneron[m]>
maybe i should run xorg with this?
<alyssa>
getting trace output from xorg is nontrivial
<alyssa>
at least on debian
<alyssa>
because xorg is a wrapper that eats the env vars
<alyssa>
(you could patch out the TRACE check from gallium/drivers/panfrost though)
<jenneron[m]>
alyssa: i can't run anything in xorg since it hangs https://dpaste.com/284XTGUQK in a few seconds when i try to do something in UI, but i've taken sway log with `PAN_MESA_DEBUG=sync,trace`, not sure this is useful https://dpaste.com/6N9QDDV8K
<jenneron[m]>
i use older kernel than before and it didn't hang for me, probably i should upgrade it, this one is quite old
<jenneron[m]>
this is problematic with cracked display, again
<jenneron[m]>
but, again, glmark2-es2 window seems fine
<jenneron[m]>
...i missed -bbuild part. should i test it again?

aha, dredged up an old presentation via Arm Developer that says T620 plus "all upcoming ARM GPUs", so that implies T604 is the lone oddity (yet again)

jenneron[m]: I'm looking for the trace that causes "Incomplete job or timeout" so I can see what causes the dmesg spam
<alyssa>
the combination of "sync" and "trace" should give that
<jenneron[m]>
the problem is that it's very unlikely that glmark2 window causes anything of what we can see in dmesg
<alyssa>
right..
<jenneron[m]>
there are no those logs when i run glmark2-es2-drm
<alyssa>
yeah, that's not going to help us then
<alyssa>
01:10 < jenneron[m]> alyssa: i can't run anything in xorg since it hangs https://dpaste.com/284XTGUQK in a few seconds when i try to do something in UI, but i've taken sway log with `PAN_MESA_DEBUG=sync,trace`, not sure this is useful https://dpaste.com/6N9QDDV8K
<alyssa>
the sway crash is interesting in its own right: automatic validation seems to be failing
<alyssa>
is it possible to get a backtrace from that?
<alyssa>
easiest way is probably `ulimit -c unlimited`, then run sway with trace,sync, then `gdb sway ./core` and `bt`
<alyssa>
if we're lucky this is a driver bug that PAN_MESA_DEBUG=trace's validation is catching for us
<jenneron[m]>
also, without `PAN_MESA_DEBUG=sync,trace` it runs, however with those glitches and logs
<alyssa>
yes! this is a good sign the :D
<jenneron[m]>
alyssa: it doesn't crash when running with gdb, i see gray screen
