drm/amd/display: Fix sending VSC (+ colorimetry) packets for DP/eDP displays without PSR

2024-01-04T14:48:15Z

The check for sending the vsc infopacket to the display was gated behind PSR (Panel Self Refresh) being enabled. The vsc infopacket also contains the colorimetry (specifically the container color gamut) information for the stream on modern DP. PSR is typically only supported on mobile phone eDP displays, thus this was not getting sent for typical desktop monitors or TV screens. This functionality is needed for proper HDR10 functionality on DP as it wants BT2020 RGB/YCbCr for the container color space.

drm/amd/display: Disable PSR-SU on Parade 0803 TCON again

2023-12-12T17:01:44Z

When screen brightness is rapidly changed and PSR-SU is enabled the display hangs on panels with this TCON even on the latest DCN 3.1.4 microcode (0x8002a81 at this time). This was disabled previously as commit 072030b17830 ("drm/amd: Disable PSR-SU on Parade 0803 TCON") but reverted as commit 1e66a17ce546 ("Revert "drm/amd: Disable PSR-SU on Parade 0803 TCON"") in favor of testing for a new enough microcode (commit cd2e31a9ab93 ("drm/amd/display: Set minimum requirement for using PSR-SU on Phoenix")). As hangs are still happening specifically with this TCON, disable PSR-SU again for it until it can be root caused.

drm/amd/display: prevent potential division by zero errors

2023-09-06T18:32:39Z

There are two places in apply_below_the_range() where it's possible for a divide by zero error to occur. So, to fix this make sure the divisor is non-zero before attempting the computation in both cases.

drm/amd/display: PQ regamma end point

2023-08-30T18:58:38Z

[WHY & HOW] PQ has a fixed range of 0-10,000 nits. Using 1=80 nits normalization, PQ should map to 1.0 for X=125.0 HW LUT used for interpolation does not have X=125 so it's interpolated. However, we cap Y to 1 for all X>=125. The closest larger HW point is 128. What we want is Y(128) such that interpolation through 125 gives 1.0. Such value is ~1.00256. Another change is to hardcode PQ table, we pretty much always have 1=80 normalization so the table can be static.
