2023-11-29drm/amd/display: Update DCN35 clock table policyNicholas Kazlauskas
[Why] The new table doesn't have an implicit mapping between Fclk SOC voltage and MemClk and it currently builds the table off of number of Fclk states rather than DcfClock states. The DML table in use is not correct for functionality or power and does not align with our existing policies for DCN3x. [How] Build the table based on DcfClock with the following assumptions: 1. Raising Soc voltage is the most expensive operation, so assume that running at max DispClock or DppClock is preferable. 2. Assume that we can run at max Fclk / MemClk at any state, but restrict the maximum state to the very last entry in the table as the worst case scenario. 3. Assume that Fclk always has a 2x multiplier on DcfClock unless the table specifies something lower.

2023-11-29drm/amd/display: Simplify brightness initializationCamille Cho
[Why] Remove the brightness cache in DC. It uses a single value to represent the brightness for both SDR and HDR mode. This leads to flash in HDR on/off.

2023-11-29drm/i915: Also check for VGA converter in eDP probeVille Syrjälä
Unfortunately even the HPD based detection added in commit cfe5bdfb27fa ("drm/i915: Check HPD live state during eDP probe") fails to detect that the VBT's eDP/DDI-A is a ghost on Asus B360M-A (CFL+CNP). On that board eDP/DDI-A has its HPD asserted despite nothing being actually connected there :( The straps/fuses also indicate that the eDP port is present. So if one boots with a VGA monitor connected the eDP probe will mistake the DP->VGA converter hooked to DDI-E for an eDP panel on DDI-A. As a last resort check what kind of DP device we've detected, and if it looks like a DP->VGA converter then conclude that the eDP port should be ignored.

2023-11-29drm/i915/gsc: Mark internal GSC engine with reserved uabi classTvrtko Ursulin
The GSC CS is not exposed to the user, so we skipped assigning a uabi class number for it. However, the trace logs use the uabi class and instance to identify the engine, so leaving uabi class unset makes the GSC CS show up as the RCS in those logs. Given that the engine is not exposed to the user, we can't add a new case in the uabi enum, so we insted internally define a kernel internal class as -1. At the same time remove special handling for the name and complete the uabi_classes array so internal class is automatically correctly assigned.

2023-11-25drm/bridge: panel: Check device dependency before managing device linkLiu Ying
Some panel devices already depend on DRM device, like the panel in arch/arm/boot/dts/st/ste-ux500-samsung-skomer.dts, because DRM device is the ancestor of those panel devices. device_link_add() would fail by returning a NULL pointer for those panel devices because of the existing dependency. So, check the dependency by calling device_is_dependent() before adding or deleting device link between panel device and DRM device so that the link is managed only for independent panel devices.

2023-11-21nouveau/gsp: allocate enough space for all channel ids.Dave Airlie
This probably isn't the ideal fix, but we ended up using chids sparsely, and lots of things rely on indexing into the full range, so just allocate the full range up front. The GSP code fixes 8 channels into a userd page, but we end up using a single userd page per channel so end up sparsely using the range. Fixes a few crashes seen with multiple channels.

2023-11-21drm/panel: boe-tv101wum-nl6: Fine tune Himax83102-j02 panel HFP and HBPCong Yang
The refresh reported by modetest is 60.46Hz, and the actual measurement is 60.01Hz, which is outside the expected tolerance. Adjust hporch and pixel clock to fix it. After repair, modetest and actual measurement were all 60.01Hz. Modetest refresh = Pixel CLK/ htotal* vtotal, but measurement frame rate is HS->LP cycle time(Vblanking). Measured frame rate is not only affecte by Htotal/Vtotal/pixel clock, also affected by Lane-num/PixelBit/LineTime /DSI CLK. Assume that the DSI controller could not make the mode that we requested(presumably it's PLL couldn't generate the exact pixel clock?). If you use a different DSI controller, you may need to readjust these parameters. Now this panel looks like it's only used by me on the MTK platform, so let's change this set of parameters.

2023-11-21drm/ast: Disconnect BMC if physical connector is connectedThomas Zimmermann
Many user-space compositors fail with mode setting if a CRTC has more than one connected connector. This is the case with the BMC on Aspeed systems. Work around this problem by setting the BMC's connector status to disconnected when the physical connector has a display attached. This way compositors will only see one connected connector at a time; either the physical one or the BMC.

2023-11-20drm/i915: do not clean GT table on error pathAndrzej Hajda
The only task of intel_gt_release_all is to zero gt table. Calling it on error path prevents intel_gt_driver_late_release_all (called from i915_driver_late_release) to cleanup GTs, causing leakage. After i915_driver_late_release GT array is not used anymore so it does not need cleaning at all.

2023-11-20drm/i915/dp_mst: Fix race between connector registration and setupImre Deak
After drm_connector_init() is called the connector is visible to the rest of the kernel via the drm_mode_config::connector_list. Make sure that the DSC AUX device and capabilities are setup by that time. Another race condition is adding the connector to the connector list before drm_connector_helper_add() sets the connector helper functions. That's an unrelated issue, for which the fix is for a follow-up. One solution would be adding the connector to the connector list only during its registration in drm_connector_register().
