drm/tegra: prime: Implement ->{begin,end}_cpu_access() (2018-03-17 00:04:20 +0100)
Apologies for the delay. I originally wanted to send this out on Friday
but then ran into a pair of bugs that I thought might be caused by this
branch. Turns out that they were both already broken in v4.16-rc1 and I
just hadn't tested for the corner case, so I caught them only very late
in the release cycle.
Anyway, the fixes for that are on the drm/tegra/fixes branch for which
I sent an updated pull request earlier. The stuff here's fairly trivial
and incremental improvements.
Thanks,
Thierry

drm/tegra: Changes for v4.17-rc1
This fixes mmap() for fbdev devices by providing a custom implementation
based on the KMS variant. This is a fairly exotic case these days, hence
why it is not flagged for stable.
There is also support for dedicating one of the overlay planes to serve
as a hardware cursor on older Tegra that did support hardware cursors
but not RGBA formats for it.
Planes will now also export the IN_FORMATS property by supporting the
various block-linear tiling modifiers for RGBA pixel formats.
Other than that, there's a bit of cleanup of DMA API abuse, use of the
private object infrastructure for global state (rather than subclassing
atomic state objects) and an implementation of ->{begin,end}_cpu_access
callbacks for PRIME exported buffers, which allow users to perform cache
maintenance on these buffers.
