08:07 <dmanlfc> hi, i'm trying to get the new Panthor driver working on a number of RK3588 boards (Mali G610).

08:07 <dmanlfc> I have compiled Mesa 24.1.1 AOK and I see the Panthor DRI driver

08:09 <dmanlfc> The Mali firmware is also in /lib/firmware/arm/mali/arch10.8

08:09 <dmanlfc> I have tried numerous kernels which have the Panthor DRM module either backported or the 6.10-RC

08:10 <dmanlfc> The boards I have tested Rock5b is the main test board, the DTS has appropriate Panthor nodes too

08:10 <dmanlfc> does anyone have some guidance on what I might be missing?

08:15 <dmanlfc> happy to share logs accordingly

08:53 <daniels> dmanlfc: yeah, first step would be to explain the actual error you're seeing, post logs of dmesg, etc

09:27 <dmanlfc> thanks - details are here - https://gitlab.freedesktop.org/mesa/mesa/-/issues/11345

09:28 <dmanlfc> i do think it's a configuration problem on my end but i can't nail it...

09:30 <dmanlfc> although others are seeing EGL errors elsewhere, so it could be a bug

09:34 <dmanlfc> i see this in the latest changelog - `egl: fix teardown when using xcb`

09:35 <dmanlfc> i will try 24.1.2 now

09:36 <daniels> I'd be looking at the kernel

09:37 <daniels> what's the output of ls -lh /sys/class/drm ?

09:37 <dmanlfc> i agree as the panthor module isn't loading

09:37 <dmanlfc> 1 min I will fire up the board

09:39 <kusma> One easy option is to use an image from here, they have everything set up already: https://gitlab.collabora.com/hardware-enablement/rockchip-3588/debian-image-recipes

09:40 <daniels> right, if the panthor module isn't loading, then that's your problem, not mesa :)

09:40 <kusma> But if you don't want to throw out the baby with the bathwater, just figuring out why the panthor DRM driver isn't loading is probably a good step, dmesg with some grepping can usually help with that.

09:42 <dmanlfc> kusma, dmesg doesn't show any failures

09:42 <dmanlfc> and if i modprobe panthor it loads

09:43 <kusma> Here's what I get from dmesg | grep panthor: https://gitlab.collabora.com/-/snippets/387

09:44 <kusma> I'm on an older kernel, though.

09:45 <dmanlfc> thanks kusma

09:45 <dmanlfc> note: we're buildroot based, not debian, just as a fyi

09:46 <kusma> Fair, but probably shouldn't matter most, though.

09:47 <dmanlfc> i agree if everything is in place as i think i have it

11:58 <dmanlfc> sorted it, i fixed the rk3588s.dtsi gpu node

11:58 <dmanlfc> we have lift off!

12:32 <daniels> nice!
