drm/amd/display: Update clock table to include highest clock setting

2023-03-07T20:57:13+00:00

[Why]
Currently, the clk manager matches SocVoltage with voltage from
fused settings (dfPstate clock table). And then corresponding clocks
are selected.

However in certain situations, this leads to clk manager not
including at least one entry with highest supported clock setting.

[How]
Update the clk manager to include at least one entry with highest
supported clock setting.

drm/amd/display: fix shift-out-of-bounds in CalculateVMAndRowBytes

2023-03-02T03:43:19+00:00

[WHY]
When PTEBufferSizeInRequests is zero, UBSAN reports the following
warning because dml_log2 returns an unexpected negative value:

  shift exponent 4294966273 is too large for 32-bit type 'int'

[HOW]

In the case PTEBufferSizeInRequests is zero, skip the dml_log2() and
assign the result directly.

drm/amd/display: only warn once in dce110_edp_wait_for_hpd_ready()

2023-02-23T22:35:58+00:00

Since, hot plugging eDP displays isn't supported, it is sufficient for
us to warn about the lack of a connected display once. So, use ASSERT()
in dce110_edp_wait_for_hpd_ready() instead of DC_LOG_WARNING().

drm/amd/display: disable SubVP + DRR to prevent underflow

2023-02-16T03:26:22+00:00

[Why&How]
Temporarily disable SubVP+DRR since Xorg has an architectural limitation
where freesync will not work in a multi monitor configuration. SubVP+DRR
requires that freesync be working.

Whether OS has variable refresh setting enabled or not, the state on
the crtc remains same unless an application requests VRR. Due to this,
there is no way to know whether freesync will actually work or not
while we are on the desktop from the kernel's perspective.

If userspace does not have a limitation with multi-display freesync (for
example wayland), then this feature can be enabled by adding a
dcfeaturemask option to amdgpu on the kernel cmdline like:

amdgpu.dcfeaturemask=0x200
