Lima userspace drivers: Xorg/mesa/tools/etc for BPI-R2

Banana Pi Router design
41

Just in case - configuring latest git mesa in debian:

meson ./build --buildtype plain --libdir lib/arm-linux-gnueabihf --localstatedir /var/lib --prefix /usr --sysconfdir /etc --wrap-mode nodownload -Dplatforms=surfaceless,x11,drm -Dllvm=true -Dlmsensors=false -Dlibunwind=false -Dgallium-nine=false -Dgallium-va=false -Dgallium-vdpau=false -Dgallium-xa=false -Dgallium-xvmc=false -Dgallium-opencl=disabled -Dosmesa=none -Dbuild-tests=false -Dglx=dri -Dshared-glapi=enabled -Ddri3=true -Degl=true -Dgbm=true -Dgles1=disabled -Dgles2=enabled -Dglvnd=false -Dselinux=false -Dvalgrind=false -Ddri-drivers= -Dgallium-drivers=kmsro,lima,swrast

P.S. meson-0.55 has to be installed from debian sid. Patch is the same.

P.P.S. building in progress, so not yet tested.

It would be nice if we got crosscompile working so i can build on travis and pack deb-package

Btw. Hdmi-patches are on the way to get merged to mainline (5.10).

https://git.kernel.org/pub/scm/linux/kernel/git/chunkuang.hu/linux.git/log/?h=mediatek-drm-next

I hope Matthias picks dts changes too

43

I’m not so familiar with travis, is it some debian related stuff? I have some gentoo-related progress on cross-compiling, but it’s still far from finishing. Now when i have 2nd R2 which is debian powered i’m open to new debian things :wink:

Great news, but we also need lima patches (dts-related are more likely to be accepted than drm-related)

Btw: some new lima “fun” ;):

Not very playable performance, but at least it runs, opposite to earlier versions.

travis is a CI/CD (continous integration/delivery/deployment) which builds my kernel on github automaticly on push (only main-branch selected in .travis.yml). it builds kernel with my build.sh…

so if we find a way to build mesa with crosscompile and pack into deb (maybe include into build.sh) i can integrate it to travis so it will be automaticly build

btw. i cannot see your video (wrong mime) in firefox

45

Same for me in firefox, works in chromium based browser.

gaming on router :slight_smile: my intention was more to have a more responsive x-server

47

Gaming on a router with a GPU and HDMI :wink:

P.S. Probably it’s possible to use dts overlay for lima init? It will let to leave the kernel’s lima driver as is?

48

How do you want to trigger lima power on/off by dts? Currently we have only a code-approach. And this i can add to code in my repo and it is triggered by module load

49

In my 5.5-lima i used the same approach as in 4.4-mali module - dts regulators. Literally ported part of dts from 4.4 to 5.5. So now i want to try use it as an overlay.

50

We can define it in bananapi.dts disabled so you to enable it only in your overlay

I see you have also code changes in the mentioned commit…

You can rebase needed changes on my 5.9-hdmi, then i can include it in my repo in future

51

All code changes are for debug only.

Ok, i can try.

52

to be continue in Mali-450 support by lima :slight_smile:

53

Seems like crosscompiling mesa is possible without additional vm

https://sunxi.org/Mali_Open_Source_Driver#Cross_Compiling

54

Looks like it’s for debian, so i’ll need an additional VM :slight_smile:

55

But the binaries created will only work on debian because they are linked to debian libs :slight_smile:

56

Maybe chroot variant is best way…maybe that can be used also for other versions

Create a chroot and run build-process inside

Mali-450 support by lima => 20.0.x to have no unstable depency (meson 0.49.2 from debian 10)

57

successfully build mesa inside chroot

buildchroot.sh (1,2 KB)

build_mesa.sh (1,3 KB) mesa.patch (1017 Bytes)

sudo cp build_mesa.sh mesa.patch debian_buster_armhf/root/
sudo chroot debian_buster_armhf /root/build_mesa.sh

built files here: https://drive.google.com/file/d/1cNdpbW7cOSbvQPLc72KsdwwFxJMuY8az/view?usp=sharing

58

Great! Did you tested it? (I mean stability, blinking menus/buttons etc.)

59

Not yet due to missing time

60

Recently mediatek entry point patch was accepted to mesa mainline.

So now it’s not nessesery to patch mesa for git master.

UPD: Just finished testing - everything compiles and works just great with latest sources from git.
