<jenneron[m]> <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]> alyssa: managed to get this with glmark2-es2 https://dpaste.com/3N73XNKXW
<jenneron[m]> dmesg while running this https://dpaste.com/EKFTCP8LF
<jenneron[m]> uh, i've got more of them this time https://dpaste.com/CCEWK5YRN
<jenneron[m]> but, again, glmark2-es2 window seems fine
<jenneron[m]> ...i missed -bbuild part. should i test it again?

<robmur01> 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)

<alyssa> robmur01: delightful
<alyssa> 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
<jenneron[m]> nevermind

<alyssa> invalid renderer state descriptor, I guess
<alyssa> I wonder what might cause that, hmm
<alyssa> accessing unmapped memory ... is this an overflow? a use-after-free? something else?
<alyssa> gpu_va=13184921368304182584
<alyssa> this seems like garbage
<alyssa> this is really weird ... not sure how to go about debugging this remotely.
<alyssa> to narrow down the cause I guess I would next try https://rosenzweig.io/0001-hack.patch
<alyssa> I expect either nothing will change, or the faults will go away and sway will work except for black rectangles everywhere.

<jenneron[m]> <alyssa> "this is really weird ... not..." <- is this T604-specific?
