alyssa: Are the requirements minimal enough that returning a number with an exponent that's off by 127 is okay?

<alyssa>
err......
<alyssa>
that, er, no i don't think so....

robclark: Random OT question. Is the Chrome/ChromeOS Android compatibility layer open source? It's a hard topic to search for
<robclark>
I think the wayland glue layer is all in the open src chromium tree.. the android side of it is maybe not all open src for android reasons
<HdkR>
Huh
<robclark>
I don't really claim to understand the reasoning on android side of things.. I guess some things like play store access are a bit more tightly controlled but a lot of it is just boring plumbing
<HdkR>
It's a bit weird because yea, it's just plumbing everything
<robclark>
android folks are weird
<robclark>
but.. I deal with it.. modulo fex we don't really have any insteresting/challenging workloads for arm specific gpu drivers
<HdkR>
Not many projects bring 50k new applications with significantly harder requirements than every previous game :D
<robclark>
play store has some interesting workloads.. but at the same time they are things that aren't just dumb for mobile GPU's (ie. not relying on a bunch of legacy gl things)
<HdkR>
:D
<HdkR>
Proton will likely be working in a week or two. So wackload of Windows games will just work
<robclark>
ofc at this point in time, moar fps is a lot more cpufreq / gpu-devfreq tuning than mesa opts.. having best shader compiler in the world does no good if you are running at low freq when you should be running in go-fast mode ;-)
<robclark>
(esp when vblank stalling enters the picture)
<robclark>
(and then there is the time you realize you need to fake GL_RENDERER to get games to not throttle themselves :-/)
<HdkR>
I look forward to Freedreno lying saying it is some desktop GPU
<robclark>
heh, tbf android games would be equally confuses about a desktop GPU as unknown open src drivers
<robclark>
but with my recent patches, you can use env vars to override thanks to driconf
<HdkR>
I'm sure a few of those SHIELD optimized games would benefit from an override
<HdkR>
Only a few of those on Android though
<robclark>
if you've got a list of games, I could take a look
<robclark>
I've been going thru play store games trying to find things that need overrides
<robclark>
mostly just going thru things that rank highly on play store.. but I guess that is just scratching the surface
<HdkR>
The one I remember off hand is Dead Trigger
<HdkR>
It very well could have updated to ES 3.0 though
<robclark>
I'll take a look.. mostly I've just been trying qcom vendor/renderer strings but maybe I need to expand my treachery :-P
<HdkR>
That one was Tegra 4 era if you need a target to shoot for
<robclark>
was tegra4 before or after nv gave up on their half bakes mobile gpu?
<robclark>
probably not interesting if before
<HdkR>
Tegra 4 was the final mobile GPU before kepler being pushed in to mobile space
<HdkR>
Supports a bunch of ES 3.0 things but not quite ES 3.0 :D
<robclark>
ok.. probably not interesting I guess
<HdkR>
Trying to sideload most any of the Lightspeed Studios ported games wouldn't work sadly
<robclark>
even small core a6xx is going to run circles around the nv mobile gpu... newer things with a lot more memory bandwidth might be interesting but games that optimize for that are maybe not optimized right for tilers
<robclark>
I wonder what patches nv has for desktop gl on android..
<HdkR>
Biggest one is that it rips the Android libEGL out. Which is woefully underequipped to handling libGL
<robclark>
right

wonders why the window stops updating for DarkPlaces running with Gallium Nine when panfrost_clear_render_target is called

It seems that util_blitter_clear_render_target is not restoring the clear colour...
<icecream95>
But... the clear colour is just vertex attributes, so it shouldn't affect anything else...
<icecream95>
Ohhh.. or is it because the clear colour's alpha makes it so that the final frame ends up fully transparent, so it doesn't change anything when Wine composites it to the virtual desktop
<HdkR>
Woo RGBA versus RGBX?

HdkR: you might want to look into https://github.com/Anbox-halium/ which confusingly isn't related much to anbox aside from fact that they both run android apps in a container afaict
<HdkR>
I've not really looked at any Android container projects
<HdkR>
I personally don't have a desire to run any Android application
<macc24>
anyway i just popped here to say i'll be gone, if any one of y'all needs to reach me good luck :p
