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.

the encoder and the crtc have a chance to write their corresponding

encoder->enable().  But if only plane's have changed, we want to do
this from crtc->commit().

The start_mask was a previous attempt to handle this, but it didn't
really do the right thing since atomic conversion.

Instead track in the crtc state that the start should be deferred,
set to try from encoder's (or in future writeback's) atomic_check().
This way the state is part of the atomic state, and rollback can
work properly if an atomic test fails.

Interrupt commands causes the CP to trigger an interrupt as the command

CP_WAIT_FOR_IDLE workaround found for a306, which would cause the CP to
wait for the GPU to go idle before triggering the interrupt.

Instead we can set the (undocumented) BIT(31) of the CACHE_FLUSH_TS

the GPU as the write event is processed.

6 years agodrm/amd/display: Correct the plane enumeration order (v2)
Shirish S [Tue, 27 Feb 2018 09:18:13 +0000 (14:48 +0530)]
drm/amd/display: Correct the plane enumeration order (v2)

The order of planes is given by the order they are enumerated
by kms.
Planes with a higher ID appears above planes with a lower ID.

Currently the planes are enumerated in the wrong order,
putting the nv12 only plane after the two RGBA planes.

This patch corrects the plane enumeration order such that all
the overlay planes are initialized first then the primary planes.

Due to this change in order the dc_add_plane_to_context() shall
receive the planes in reverse order hence this patch reverses
the parsing of planes in DM side itself.

v2: drop local reverse macro for upstream
