[Buildroot] defconfig with wayland support?

[Buildroot] defconfig with wayland support?

[Michael Despault]

[-- Attachment #1.1: Type: text/plain, Size: 1188 bytes --]

I'm struggling to get a buildroot generated system up and running that has
working wayland support.  My primary goal is simply to be able to get an
embedded system that can run and display wayland applications, using the
buildroot system.  I've found examples of other configs that claim to have
X11 support, but nothing on wayland.  Poking around in "make menuconfig"
I've done what I can to enable any wayland/weston related options, but
currently I'm hitting this build error:

Run-time dependency libdrm found: NO (tried pkgconfig and cmake)
output/build/wlroots-0.14.1/meson.build:99:0: ERROR: Dependency "libdrm"
not found, tried pkgconfig and cmake

This happens when I try and build meson.  Has anyone had success getting an
embedded system (via buildroot) going with wayland working out of the box?
Hoping someone would be able to share their defconfig file with the
appropriate options, or at least share the essential components to enable
in make menuconfig.  Barebones is fine and not concerned so much about
architecture right now, but currently testing on X86_64 with the intent to
target aarch64 eventually.

Thanks,
Mike

There is one critical piece of information that you forgot to provide:
what is your HW platform. Indeed, depending on which GPU it has, the
Buildroot configuration will have to be different to provide the right
OpenGL implementation. It's not possible to provide a "Wayland
configuration" that works everywhere.

Best regards,

Thomas

Hi Thomas,

My goal is to get Wayland running on the rk3399 SoC, which is an AArch64
architecture.  The GPU is a Mali-T860.  It seems this is indeed possible,
based on this article:
https://www.collabora.com/news-and-blog/blog/2019/08/06/rockpi-panfrost-wayland/

So I'd be using Panfrost I suppose.

Hi Michael and Thomas,

I give my 2 cents,

You have 2 possible approaches:
1) use panfrost by enabling mesa3d package
2) use mali-driver + rockchip-mali(proprietary Rockchip blobs)

In both cases it should work with Wayland 3d Accelerated. I don't have a
RK3399 board here to test it unfortunately.

Best regards
