configs: arm64/bcm2711: Enable V3D

[phire]

This allows for 3d acceleration with a 64bit kernel on the Pi 4.

---

I tested with the existing 32bit raspbian run time. I assume it will work with a 64bit run time once you recompile mesa.

Relates to #3032

[pelwell]

The arm64 bcm2711_defconfig should defiine ARCH_BCM=y, like the 32-bit version.

[phire]

ARCH_BCM wasn't defined at all for arm64, so I added it.

[lategoodbye]

Please keep your original change by adding ARCH_BCM2835.

[phire]

Do you still want ARCH_BCM to be defined?

[lategoodbye]

I don't think this is necessary.

[sakaki-]

Seems to work well!

I have added this PR to my bcm2711-kernel-bis weekly autobuild pro tem, until it is merged upstream. A prebuilt release tarball may be downloaded here.

Screenshot (64-bit Gentoo userland, also has #3144 applied for bounce buffers / 4GiB RAM):

Thanks, sakaki

[pelwell]

@lategoodbye requested the use of ARCH_BCM2835 instead rather than ARCH_BCM, which makes for a smaller commit, but the end result is the same.

[yrzr]

@sakaki- Hi, could you please help me with the problem here? I cannot figure it out.

[pelwell]

What problem?

[pelwell]

Thanks, @phire - I've merged the simpler (ARCH_BCM2835) version of your patch.

[pelwell]

With a typo in the commit title. Ho hum.

[sakaki-]

What problem?

@pelwell, I think, looking at the screenshot, what @yrzr means that he isn't getting V3D 4.2 showing up on glxgears -info for GL_RENDERER, but the fallback llvmpipe instead.

Well, a little OT ^-^, but the issue here is userland, not kernel: media-libs/mesa-19.1.4 needs to be built with the v3d gallium configuration option set, which is not in the main-tree Gentoo ebuild atm. (You also need vc4 present in VIDEO_CARDS in make.conf o/c.)

The line you need to add to your mesa ebuild is this one (or something with the same effect).

hth, sakaki

[yrzr]

@sakaki- Thanks for your replay. I have already used the ebuild from your overlay and enabled video_cards_vc4. Still wondering what I have missed.

@yrzr,
happy to follow up on this with you, but could you please open an issue against my overlay instead, to avoid taking this thread too far off topic?
Thanks, sakaki
