14:31 <KamikazeOther> Hi. I'm trying to get panfrost working on my firefly RK3399, which has a Mali T860MP4. I'm using Arch Linux ARM with a custom compiled 5.16.0-rc7 with panfrost compiled as a module. On userspace I have latest available mesa (21.3.3) & X (1.21.1.2) just from the package manager. My understanding was that I shouldn't need to do much else and the modeset driver would then somehow know to use panfrost for DRI, but it always uses llvmpipe. I am

14:31 <KamikazeOther> unsure what I should do from here.

14:32 <jakllsch> KamikazeOther: i'd check with people who know about DRI/DRM and Mesa

14:32 <jakllsch> if it's a userland issue, they're more likely to guess what it is

14:33 <KamikazeOther> cheers, any idea where would that be?

14:33 <jakllsch> https://docs.mesa3d.org/lists.html#irc

14:34 <mps> KamikazeOther: don't know for arch linux but it works fine on my samsung rk3399 chromebook (gru-kevin) on alpine linux

14:35 <KamikazeOther> mps: do you have any custom xorg config ?

14:35 <mps> KamikazeOther: no, except for libinput

14:35 <mps> but that is not related

14:49 <KamikazeOther> mps: did you have to compile anything from scratch? e.g. mesa+gallium drivers? or did everything work out of the box on alpine?

14:52 <mps> KamikazeOther: nothing, everything as it is on alpine userspace

14:53 <KamikazeOther> is panfrost compiled into the kernel or a module on alpine? I've noticed I get no kernel message output when panfrost is loaded...

14:53 <mps> kernel is somewhat special for kevin chromebook but nothing special for graphic part

14:53 <mps> as a module

14:54 <KamikazeOther> do you see any kernel message output in your logs when it's loaded?

14:54 <mps> yes, but forgot what (about panfrost loaded and some parameters)

14:55 <KamikazeOther> hmm. ok thanks.

14:56 <mps> KamikazeOther: https://git.alpinelinux.org/aports/tree/testing/linux-gru this is alpine build script and files

14:56 <mps> for kernel, I mean

14:57 <mps> side note, and I'm maintainer of this pkg

14:57 <KamikazeOther> much appreciated

16:25 <KamikazeOther> a smart person in the #panfrost channel realised my DTS (rk3399-firefly.dts) didn't have any final GPU enablement within it. After adding a clause like this one (https://github.com/torvalds/linux/blob/master/arch/arm64/boot/dts/rockchip/rk3399-orangepi.dts#L235 ) the panfrost kernel driver is now working, and I now have panfrost rendering in X

16:25 <KamikazeOther> (sorry that was panfrost on another IRC server)

16:26 <KamikazeOther> seeya all :)
