8 months agodrm/amd/display: Fix out-of-bounds access in 'dcn21_link_encoder_create'
Srinivasan Shanmugam [Wed, 25 Sep 2024 14:34:15 +0000 (20:04 +0530)]
drm/amd/display: Fix out-of-bounds access in 'dcn21_link_encoder_create'

An issue was identified in the dcn21_link_encoder_create function where
an out-of-bounds access could occur when the hpd_source index was used
to reference the link_enc_hpd_regs array. This array has a fixed size
and the index was not being checked against the array's bounds before
accessing it.

This fix adds a conditional check to ensure that the hpd_source index is
within the valid range of the link_enc_hpd_regs array. If the index is
out of bounds, the function now returns NULL to prevent undefined
behavior.

8 months agodrm/amd/display: Clip rect size changes should be full updates
Joshua Aberback [Thu, 12 Sep 2024 22:47:22 +0000 (18:47 -0400)]
drm/amd/display: Clip rect size changes should be full updates

[Why]
In cases where an MPO plane is being dragged around partially off-screen,
it is possible to get a flip where the only scaling parameters to change
are the clip rect size and position. Currently, clip rect size changes
are considered medium updates, which can result in the clip rect being used
for HW programming being larger than the clip rect that was used for the
last DML validation. This can lead to mismatches in different parts of the
pipe and can result in a p-state hang.

[How]
 - consider clip rect size changes scaling changes, therefore full updates
 - refactor get_scaling_info_update_type for clarity
 - remove clip_size_change update flag

Clip rect size changes were previously demoted from full updates as an
optimization when the MPO + ODM policy changed to always pre-allocate MPO
pipes, but it created the issue described above. Personally testing this
use case, the performance feels fine with full update spam, and we expect
this is a fairly infrequent use case. If the performance needs to be
optimized in the future, consider reworking the entire update type logic
to run a DML pass and determine the update type based on what DML says
will actually change.

drm/amd/display: Block UHBR Based On USB-C PD Cable ID

[WHY]
Currently the absence of UHBR cable ID caps from USB-C PD does not block UHBR
rates. In situations where DPCD reports valid UHBR capability but USB-C PD
does not, such as using a USB-C to DP1.4 dongle connected to a native DP2.1
cable, link loss and lightup failures can be seen as a result.

Additionally, in edge cases where a platform supports cable ID but DMUB
doesn't correctly return cable ID caps, driver currently also allows UHBR.

[HOW]
Block UHBR rates over DP alt mode if cable id indicates no UHBR support.
Additionally, block UHBR rates if a cable ID supported platform receives no
reply from a DMUB cable id query.
