[Mesa-dev] [RFC] panfrost: Add DRM backend

[Tomeu Vizoso]

Hi,

the patches in this series get Panfrost working with the DRM driver that
Rob Herring and I have been working on lately:

https://gitlab.freedesktop.org/panfrost/linux/tree/panfrost-5.0-rc4

I get roughly the same demos working with it as with Arm's driver, but
there's lots of improvements to be made (mostly in the kernel) to how
memory is managed and jobs are scheduled.

The priority right now is to gain some confidence that the UABI is
right, and that's why I thought to send the code at this stage.

The patches in this MR are needed so the nondrm backend keeps working:

Thanks,

Tomeu
