Currently the GGTT offset of a UV plane in a semiplanar YUV FB is tile
size (4kB) aligned. I noticed, that enforcing only this alignment leads
oddly to random memory corruptions on TGL while scanning out Y-tiled
FBs. This issue can be easily reproduced with a UV plane offset that is
not aligned to the plane's tile row size.
Some experiments showed the correct alignment to be tile row size
indeed. This also makes sense, since the de-tiling fence created for the
object - with its own stride and so "left" and "right" edge - applies to
all the planes in the FB, so each tile row of all planes should be tile
row aligned.
In fact BSpec requires this alignment since SKL. On SKL we may enforce
this due to the AUX plane x,y coords check, but on ICL and TGL we don't.
For now enforce this only on TGL; I can follow up with any necessary
change for ICL after more tests.
BSpec requires a stricter alignment for linear UV planes too (kind of a
tile row alignment), but it's unclear whether that's really needed
(couldn't be explained with the de-tiling fence as above) and enforcing
that could break existing user space; so avoid that too for now until
more tests.
v2:
- Clarify the commit log wrt. the address space the alignment applies to.

At least one framebuffer plane on TGL - the UV plane of YUV semiplanar
FBs - requires a non-power-of-2 alignment, so add support for this. This
new alignment restriction applies only to an offset within an FB, so the
GEM buffer itself containing the FB must still be power-of-2 aligned.

be 0).

Due to DDB overlaps the pipe enabling sequence is not always crescent.
As the previous patch selects the smallest pipe/transcoder in the MST
stream to be master and it needs to be enabled first, this changes
were needed to guarantee that.
So first lets enable all pipes that do not need a fullmodeset as
those don't have any external dependency and those are the ones that
can overlap with each other.
Then on the second loop it will enable all the pipes that needs a
modeset and don't depends on other pipes like MST master
pipe/transcoder.
Then finally all the pipes that needs a modeset and have dependency
on other pipes, that at this point are alread enabled.
v3: rebased
v4:
- added check for modeset_pipes too to decide if is necessary for a
wait a vblank
- added DDB allocation overlap check for pipes that needs a modeset

On TGL the blending of all the streams have moved from DDI to
transcoder, so now every transcoder working over the same MST port must
send its stream to a master transcoder and master will send to DDI
respecting the time slots.
So here adding all the CRTCs that shares the same MST stream if
needed and computing their state again, it will pick the lowest
pipe/transcoder among the ones in the same stream to be master.
Most of the time skl_commit_modeset_enables() enables pipes in a
crescent order but due DDB overlapping it might not happen, this
scenarios will be handled in the next patch.
v2:
- Using recently added intel_crtc_state_reset() to set
mst_master_transcoder to invalid transcoder for all non gen12 & MST
code paths
- Setting lowest pipe/transcoder as master, previously it was the
first one but setting a predictable one will help in future MST e
port sync integration
- Moving to intel type as much as we can
v3:
- Now intel_dp_mst_master_trans_compute() returns the MST master transcoder
- Replaced stdbool.h by linux/types.h
- Skip the connector being checked in
intel_dp_mst_atomic_master_trans_check()
- Using pipe instead of transcoder to compute MST master
v4:
- renamed connector_state to conn_state
v5:
- Improved the parameters of intel_dp_mst_master_trans_compute() to
simply code
- Added call drm_atomic_add_affected_planes() in
intel_dp_mst_atomic_master_trans_check() as helper could not do it

- Removed "if (ret)" left over from v3 changes

Gen-12 display decompression operates on Y-tiled compressed main surface.
The CCS is linear and has 4 bits of metadata for each main surface cache
line pair, a size ratio of 1:256. Gen-12 display decompression is
incompatible with buffers compressed by earlier GPUs, so make use of a new
modifier to identify gen-12 compression. Another notable change is that
render decompression is supported on all planes except cursor and on all
pipes. Start by adding render decompression support for [A,X]BGR888 pixel
formats.
v2: Fix checkpatch warnings (Lucas)
v3:
Rebase, disable color clear, styling changes and modify
intel_tile_width_bytes and intel_tile_height to handle linear CCS
v4:
- Use format block descriptors and the i915 specific func to get the
subsampling for each color plane.
- Use helpers to convert between CCS and main planes.
v5:
- Fix subsampling returned by intel_fb_plane_get_subsampling() for
the CCS plane of the first plane.
v6:
- Rebased on v2 of patch 4.
v7:

Move all of haswell_crtc_disable() into the encoder
.post_disable() hooks. Now we're left with just
calling the .disable() and .post_disable() hooks
back to back.
I chose to move the code into the .post_disable() hook instead
of the .disable() hook as most of the sequence is currently
implemented in the .post_disable() hook.
We should collapse it all down to just one hook and then the
encoders can drive the modeset sequence fully. But that may
need some further refactoring as we currently call the
ddi .post_disable() hook from mst code and we can't just
replace that with a call to the ddi .disable() hook.
Should also follow up with similar treatment for the enable
sequence but let's start here where it's easier.

In order to eliminate intel_pipe_to_cpu_transcoder() (and its

assert_pipe() so we don't have to do the pipe->cpu transcoder
lookup on HSW+.
On VLV/CHV this can get called during eDP init, which
happens before crtc->config->cpu_transcoder is even
populated. So currently we're always reading PIPECONF(A)
there even if we're trying to check the state of some
other pipe.
