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
<macc24> also
<macc24> when firefox window is fullscreened, the scrolling is really laggy
<macc24> where the weirdness comes in - there seems to be a cutoff between 'really good' and 'laggy'
<macc24> i have opengl acceleration enabled in firefox
<macc24> it looks like it happens on terminal windows too
<macc24> and content tht is displayed is (mostly) fine
<macc24> keyboard input is lagless too
<HdkR> GPU saturated to the point that presentation is having a hard time keeping up?
<macc24> but when i scroll using my keyboard it's fine
<macc24> i should check with other mouse
<macc24> with my other mouse it is laggy too
<macc24> touchscreen - even worse
<macc24> when i have window at fullscreen size with most of it offscreen it is good

<macc24> at this point i don't know if i'm imagining it or not, but it looks like youtube video seems to help it by forcing fps of firefox to 60

<bbrezillon> macc24: can you compile in debug optimized mode or provide me with an apitrace I can replay?
<bbrezillon> icecream95: any chance you could have a look at https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/7821 ?
<macc24> bbrezillon: yeah i can recompile in debug optimized mode

<icecream95> bbrezillon: I can't see anything obviously wrong with your re-ordering of two function calls, though you should add a Suggested-by to the commit message
<icecream95> I am slightly worried about the possibility of there eventually being a case where the space required for the BO increases after format conversion
<bbrezillon> icecream95: I'll add the suggested-by
<bbrezillon> tiled -> linear conversion should always fit in the allocated BO
<bbrezillon> but I can add an assert if you want

<macc24> ok bbrezillon i recompiled mesa with debugoptimized option
<macc24> now what to do after reproducing bug
nlhowell has quit [Ping timeout: 260 seconds]
<bbrezillon> macc24: your backtrace should now contain lines :)
<macc24> not much has changed in backtrace
<bbrezillon> hm, that's weird
<bbrezillon> macc24: are you sure /opt/lib/aarch64-linux-gnu/dri//mediatek_dri.so is the one you just compiled?
<macc24> i think so
<macc24> will recompile it just to be sure
* macc24 regrets executing "rm -rf build"
<macc24> bbrezillon: so it wasn't one that i just compiled
<macc24> here's better backtrace https://bpa.st/D4RA
<bbrezillon> macc24: ok, I think I'll need an apitrace to debug that one
<bbrezillon> it's something in panfrost_ptr_map() but I can't find out easily without reproducing locally
<macc24> bbrezillon: i can't get application.trace of it
<macc24> i run apitrace mpv video.mp4, it does segmentation fault thing and then it exits without leaving the trace
<macc24> ok i got it, had to switch to egl api in apitrace

<macc24> after building mesa from bifrost-gles3-ci
popolon has joined #panfrost
<bbrezillon> macc24: nothing special, I just pointed it out because you asked if there were Bifrost fixes in the pipe
