13:59 <thecycoone1> any advice on using apitrace for webgl (or at all). I got the following output, in the console and my tab crashed as soon as it opened the webgl. https://pastebin.com/tTaTv8SQ

14:15 <thecycoone1> Seeing slower than expected performance, and a render issue with the background until the camera is moved on https://flack.undo.it/games/test/render.html

14:15 <thecycoone1> only on panfrost

14:15 <alyssa> thecycoone1: "only on panfrost" you should do our marketing 😂

14:19 <thecycoone1> Yey!

14:25 warpme_ has quit [Quit: Connection closed for inactivity]

14:28 <alyssa> thecycoone1: I can't even load that page, SSL error

14:29 <thecycoone1> Really? I haven't seen that

14:29 <alyssa> also, Safe Browsing is throwing a fit

14:29 <alyssa> r u a 1337 h4x0r trying to h4x my computer?????? :-p

14:31 <thecycoone1> Heh, no.

14:32 <alyssa> thecycoone1: https://www.youtube.com/watch?v=qzY80OSu5Aw

14:36 <thecycoone1> It sounds like you're ending up at the wrong place, but I don't know why. I could try hosting i suppose.

14:40 <thecycoone1> https://www.ssllabs.com/ssltest/analyze.html?d=flack.undo.it shows it should be ok, but it sounds like you're being redirected, or have some sort of firewall?

14:44 <chewitt> no issues with the flack.undo.it URL here

14:45 <chewitt> @alyssa might have an old cert chain in the browser

14:45 <chewitt> it's a valid cert

14:48 <alyssa> shrug

14:53 stikonas_ is now known as stikonas

15:01 <thecycoone1> I've put it on my server: https://sealbaker.com/test/index.html

15:03 <thecycoone1> chewitt: did you see what I'm seeing with the low fps and the odd background until dragging / scrolling?

15:04 <alyssa> regardless it is the weekend

15:04 <alyssa> which means no ~~mesa~~ mali for me

15:04 * alyssa looks awkwardly at NIR code she's writing

15:05 <thecycoone1> :D no worries, or pressure.

15:05 <chewitt> thecycoone1 i'm not using a panfrost desktop, so it works fine, but I'm not sure that's helpful :)

15:05 <chewitt> (heresy I know)

15:06 <alyssa> thecycoone1: `alyssa@maud:~/mesa/src/asahi/compiler$ vim agx_compile.c` *whistles*

15:06 <thecycoone1> :O!

15:07 <thecycoone1> definitely never take my work home with me on the weekend like that ... /me glances around

15:09 <thecycoone1> well at the very least I should go back to mesa master before dragging anyone else into it. I just wondered if there was something clearly wrong with the way I was trying to use apitrace given it blew up

15:16 <macc24> thecycoone1: on my freedreno box it's slow too

15:32 <thecycoone1> ok. It wasn't on chromeos / mali binary, or whatever my phone uses.

15:32 kaspter has joined #panfrost

15:34 <macc24> thecycoone1: try on chromium

15:39 <thecycoone1> Good suggestion. Chromium fixes the speed but not the initial render problem.

15:49 <thecycoone1> https://sealbaker.com/test/screenshot.png

15:49 <thecycoone1> so I should blame firefox (mostly)?

15:49 <macc24> alyssa: was afbc fixed on mainline rk3399?

15:58 <alyssa> macc24: it should be but YMMV

15:58 <alyssa> testing appreciated

15:58 <macc24> alyssa: how it was broken?

15:59 <macc24> is it something that i would notice immediately being broken?

15:59 <alyssa> Yes

15:59 <macc24> lemme boot up my kevin

15:59 <alyssa> but it was hidden because rk3399 doesn't usually use AFBC for scanout unless you force it

15:59 <macc24> how force?

15:59 <alyssa> the only known reproducer that doesn't involve modifying compositor code is sway with an external monitor

16:00 <alyssa> which, admitteldy I use and you immediately notice everything being completely garbled on the monitor even though the laptop screen is fine

16:00 <macc24> ok

16:03 <macc24> how to get external display working on kevin?

16:06 <alyssa> sigh

16:12 <thecycoone1> there's a kernel option and it otherwise just works iirc.

16:12 <alyssa> "just" is a streth ime

16:12 <macc24> thecycoone1: which kernel option?

16:13 <alyssa> https://old.reddit.com/r/linuxmemes/comments/mocym4/at_least_limapanfrost_works/

16:13 <thecycoone1> well I plugged in my display and it worked - ignoring the cool looking stuff on the right hand side

16:13 <alyssa> ^ oh my gosh

16:13 <alyssa> daniels: ^^

16:14 <macc24> hehehe

16:14 <macc24> upvoted

16:19 <macc24> thecycoone1: can you share your kernel config?

16:20 <thecycoone1> yep

16:20 * thecycoone1 posted a file: config-seb (216KiB) < https://matrix.sealbaker.com/_matrix/media/r0/download/sealbaker.com/mEPCrOUQdXFKSlTNuWVamTUB >

16:21 <macc24> yoink

16:21 <thecycoone1> I can't say it's exactly suited to you, I took the archlinuxarm one and trimmed it down to fit in the 32mb fiddled a little.

16:22 <thecycoone1> but it does work with external displays

16:22 <thecycoone1> that's 5.11.13

16:22 <macc24> to be honest i don't remember configuring kernel for my kevin

16:30 <thecycoone1> mesa master seems to display a plain white background instead of what's in the screenshot. As always, fixes as soon as the camera moves

16:54 <thecycoone1> I had to until 5.11 because of pwm/power issues, and after that because of the size.

16:57 <thecycoone1> But generally everything is getting into pretty good shape.

17:04 <thecycoone1> With pipewire the sound "just works" too.

17:05 <macc24> oh how's pipewire? i've been thinking of switching to it from pulseaudio

17:16 <thecycoone1> Great for me.

17:18 catfella has joined #panfrost

17:19 <thecycoone1> They're still breaking the config sometimes, so pay attention to updates, but otherwise it's gone well. There's a bug with pulse on kevin. https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/issues/1104#note_768280

22:18 <robclark> heheh, using "great" and "app" to describe kmscube seems like a bit of a stretch.. :-P

22:19 <alyssa> robclark: "boring game, do not buy 1 star / 5"

22:21 <robclark> one of these days I'll get around to writing wayland-mode for kmscube, so you can have your desktop on a spinning cube :-P

22:35 <macc24> robclark: i propose an alternative

22:35 <macc24> working around bad opengl code by writing bad patches to freedreno (:

22:37 <robclark> freedreno already has a lot of shenanigans to work around bad opengl (see FD_MESA_DEBUG=inorder).. but there is a limit to what the driver can do without violating correctness :-(

22:58 <urjaman> i've got very little clue about freedreno but something something correct? nah, be wrong in interesting ways :P
