[PATCH 0/2] Broadcom V3D driver (7268/7278)

[Eric Anholt]

Here's my first pass at submitting the DRM driver for V3D 3.x/4.x,
"v3d".  I've previously been calling this project "vc5", but given
that I also support a device that's called "vc6" already, I figured it
was time to rename.

I'm quite happy with the ABI.  My only concern as far as merging is
that without GMP support, clients can access each other's memory even
without having a GEM handle.  Authenticated DRI clients on other
platforms have been able to do so, but I would like to prevent that if
possible.  Given that I was planning on having the GMP, I didn't flag
my ioctls as requiring authentication.  If this seems like a problem,
I'd be happy to slap the authentication flag on BO submit, which I
think would be enough to match the security provided by other drivers.
I have a branch for GMP, but it's going to be a while before I finish
it, I think.

Userspace for this driver is currently merged to Mesa but the build is
disabled.  I figure I'll rename its driver to "v3d" and enable it once
this is merged.
