[ Upstream commit 262b42e02d1e0b5ad1b33e9b9842e178c16231de ]
I'm not exactly clear on what strange workflow causes people to do it,
but clearly occasionally some files end up being committed as executable
even though they clearly aren't.
This is a reprise of commit 90fda63fa115 ("treewide: fix up files
incorrectly marked executable"), just with a different set of files (but
with the same trivial shell scripting).
So apparently we need to re-do this every five years or so, and Joe
needs to just keep reminding me to do so ;)

drm_vma_node_allow() and drm_vma_node_revoke() should be called in
balanced pairs. We call drm_vma_node_allow() once per-file everytime a
user calls mmap_offset, but only call drm_vma_node_revoke once per-file
on each mmap_offset. As the mmap_offset is reused by the client, the
per-file vm_count may remain non-zero and the rbtree leaked.
Call drm_vma_node_allow_once() instead to prevent that memory leak.

commit f85c5e25fd28fe0bf6d6d0563cf83758a4e05c8f upstream.
[Why & How]
Now the vc_start_slot is controlled at drm side. When we
service a long HPD, we still need to run
dm_helpers_dp_mst_write_payload_allocation_table() to update
drm mst_mgr's relevant variable. Otherwise, on the next plug-in,
payload will get assigned with a wrong start slot.

commit cb1e0b015f56b8f3c7f5ce33ff4b782ee5674512 upstream.
[Why]
amdgpu expects to update payload table for one stream one time
by calling dm_helpers_dp_mst_write_payload_allocation_table().
Currently, it get modified to try to update HW payload table
at once by referring mst_state.
[How]
This is just a quick workaround. Should find way to remove the
temporary struct dc_dp_mst_stream_allocation_table later if set
struct link_mst_stream_allocatio directly is possible.

commit 1119e1f9636b76aef14068c7fd0b4d55132b86b8 upstream.
Looks like I made a pretty big mistake here without noticing: it seems when
I moved the assignments of mst_state->pbn_div I completely missed the fact
that the reason for us calling drm_dp_mst_update_slots() earlier was to
account for the fact that we need to call this function using info from the
root MST connector, instead of just trying to do this from each MST
encoder's atomic check function. Otherwise, we end up filling out all of
DC's link information with zeroes.
So, let's restore that and hopefully fix this DSC regression.

Stop considering VBT's static DRRS support when deciding whether
to use alternate fixed modes or not. It looks like Windows more
or less just uses that to decide whether to automagically switch
refresh rates on AC<->battery changes, or perhaps whether to
even expose a control for that in some UI thing. Either way it
seems happy to always use all EDID modes, and I guess the
DRRS/VRR stuff more or less adjusts how said modes get
actually used.
Let's do the same and just accept all the suitable looking
modes from EDID, whether we have DRRS or VRR.

be called from amdgpu_dm_encoder_destroy(). Also, we don't need to free
in amdgpu_dm_encoder_destroy() since mst_encoders[] isn't explicitly

Commit 374146cad469 ("drm/vc4: Switch to drmm_mutex_init") converted,
among other functions, vc4_create_object() to use drmm_mutex_init().
However, that function is used to allocate a BO, and therefore the
mutex needs to be freed much sooner than when the DRM device is removed
from the system.
For each buffer allocation we thus end up allocating a small structure
as part of the DRM-managed mechanism that is never freed, eventually
leading us to no longer having any free memory anymore.
Let's switch back to mutex_init/mutex_destroy to deal with it properly.

The YCC conversion matrix for RGB -> COLOR_SPACE_YCBCR2020_TYPE is
missing the values for the fourth column of the matrix.
The fourth column of the matrix is essentially just a value that is
added given that the color is 3 components in size.
These values are needed to bias the chroma from the [-1, 1] -> [0, 1]
range.
This fixes color being very green when using Gamescope HDR on HDMI
output which prefers YCC 4:4:4.

commit 79601b894849cb6f6d6122e6590f1887ac4a66b3 upstream.
Code in get_output_color_space depends on knowing the pixel encoding to
determine whether to pick between eg. COLOR_SPACE_SRGB or
COLOR_SPACE_YCBCR709 for transparent RGB -> YCbCr 4:4:4 in the driver.
v2: Fixed patch being accidentally based on a personal feature branch, oops!
Fixes: ea117312ea9f ("drm/amd/display: Reduce HDMI pixel encoding if max clock is exceeded")
