<chewitt>
can I ask what the status of panfrost on the T620 is, an Odroid XU4 (Exynos 5442) came into my posession
<chewitt>
so I might have a crack at an LE image for it .. there is prior art from Lakka
<chewitt>
so "to blob or not to blob" is the question :)
<chewitt>
but IIRC the t620 was on the lower end of priorities
<icecream95>
chewitt: Why not mix things up and make a big-endian image instead? :P
<chewitt>
if I knew what that meant I'd reply in some witty way :)
<icecream95>
LE - little endian
<chewitt>
ahh, not in my vocab
<icecream95>
(or LibreELEC, which I think is what you meant)
<chewitt>
my definition is LibreELEC
<chewitt>
and big ends are something found in car engines

So, currently panfrost seems to be working a little suboptimally for me… https://sphalerite.org/dump/panfrost-xfce.mp4 (followed by what appears to be kernel memory corruption? It dumped some garbage on the serial console and wouldn't respond to any input)
<sphalerite>
Is this still to be expected (if so understandable, I hear graphics drivers aren't trivial :) ), or am I doing something wrong? :)
<sphalerite>
Linux 5.6.5, Mesa 20.0.2, Xorg 1.20.8
<mixfix41>
if i chime at all know i probs just guessing but why wouldnt the video play what was that
<mixfix41>
well you try launching a app and it seg faults right away?
<sphalerite>
mixfix41: no, blocky artifacts all over the place in xfce's compoisiting
<mixfix41>
oh good question no my desktop are displayed completely
<mixfix41>
maybe it something with panfrost and your hardware
<sphalerite>
hm ok
<sphalerite>
lots of fault messages in the syslog, I just saw
<sphalerite>
lots of REASON: TODO there, so I guess that stuff is still WIP
<mixfix41>
what do you mean which laptop
<sphalerite>
gru-bob chromebook
<sphalerite>
rk3399
<mixfix41>
sounds pretty common whch distro?
<sphalerite>
Should work as well as anything really AFAIU, since alyssa uses a gru-kevin iirc?
<sphalerite>
NixOS — a little less common, but I'm quite involved there and would look to improve the situation if possible :)
<mixfix41>
yea they had a lug meeting here one time presenting nix i should give it a shot but hadnt been ready good to see trying to run on arm
<sphalerite>
mixfix41: hah, where?
<mixfix41>
i live minnesota
<sphalerite>
oh ok hehe
<sphalerite>
I did one in Glasgow at one point
<mixfix41>
in the states yea
<mixfix41>
oh cool
<sphalerite>
but yeah, nixos works nicely on arm for the most part. My NAS/backup server is also an rk3399 running NixOS :)
<mixfix41>
hm i use the os that has a person who first got netflix running in firefox then it transfered to arch very quickly so i can imagine nix os getting updates and i read a little about the different type of FSH
<mixfix41>
or maybe it was chrome chromium one of the two :) my memory hazy good luck with panfrost its fun i should be able to run tux i barely have any lauch of tuxkart another thing to put on the agenda
<sphalerite>
oooh yeah I need to try that
<sphalerite>
(fwiw, sway works a little better than whatever compositor XFCE uses on X)
<mixfix41>
there are compositors on x?
<mixfix41>
i think thats only used with wayland?
<urjaman>
XFWM4 has a compositor, kde has a compositor, so yes ... it's just that they sit on top of the X server, they arent the X server (as it's done on wayland)
<urjaman>
i think i even have xcompmgr on my x86 desktop (to make the openbox environment composited so that transparent windows work)
<sphalerite>
not compton? :)
<mixfix41>
oh yea i use xcompmgr
<mixfix41>
ok yea thats important perspective cause i want to learn wayland seems a pivotal moment also
<mixfix41>
thanks!
<sphalerite>
So I guess these bugs are related to the unhandled page faults with the TODO reason?
<sphalerite>
I'm just surprised that they happen while other people have recently reported in here that everything is great
<daniels>
yeah, that certainly looks like it ... I wonder if a newer Mesa might be helpful?
<daniels>
the TODO reason isn't 'TODO we need to handle this' btw, it's 'TODO we need to add a print which decodes the exact reason this should-never-happen error did actually happen'
<sphalerite>
oh!
<sphalerite>
well I'm already on the latest mesa release, so the next step would be building from git
<sphalerite>
If there are any insights at all I can help gain (with limited graphics hardware knowledge), I'd be glad to help :)

there's also lots of [ 4126.625170] [drm:analogix_dp_bridge_atomic_enable [analogix_dp]] *ERROR* Failed to disable psr -110
<sphalerite>
but I guess that's not directly related. Could be why I can't connect an external monitor though I guess

PSR is for your internal panel but failing to disable it isn't good news for sure
<sphalerite>
ah ok
<sphalerite>
any idea what the issue could be there?
<sphalerite>
One potential suspect here would be my weird boot setup, I have coreboot loading a linux which kexecs my main OS
<sphalerite>
in fact, if any other gru owners here have a nicely working boot setup that doesn't involve depthcharge I'd be really glad to hear about it (and how to do it)
