2025-04-08drm/amd/display: dont disable dtb as dto src during dpms offAusef Yousof2-5/+8
fix was previously in 25.20 but was reverted out as it was accompanied by other changes that caused regression. [why&how] Disabling dtb as the dto src during dpms off relies on in the same instance being able to also alter the dto src bit to dpref (or not dtb in general), but this was recently changed to only take place in dcn31_program_pix_clk, as that is where we want to perform any dto src changes because tg is off at that point, it is unsafe to do that elsewhere. What this means is now instead of disabling dtb as dto src and modifying source bit, we are left with the configuration for a given tg that specifies dtb as dto src and dtb dto en simultaneously is unset. dcn31_program_pix_clk can rectify this but its possible for us to perform some tg dependant operation that would simply hang because when we go to enable say crtc then, the clk we specify as dto src is "off" en bit is cleared, source bit was never changed, and program_pix_clk hasnt been called yet (as apart of dpms on) We cant disable it as dto src during dpms off if we want the luxury of performing tg dependant operation during dpms off and before dpms on.

2025-04-08drm/amd/display: wait for updates to latch before lockingAusef Yousof9-0/+175
[why&how] It is possible for an update to acquire otg lock and begin programming while the previous update has not completed and its values have not latched. The correct way to go about this is to wait until the vupdate pulses so we can be sure that previous updates have latched and we can continue with the current update pipe programming, otherwise during consecutive full updates we will have corruption flash on the screen. The corruption flash occurs specifically on configs that require odm combine, and its local to a specific pipe (will not flash across whole screen). This ticket is across the otg slave, but it may also appear across master.

2025-04-08drm/amd/display: HDCP Locality check using DMUB Fused IODominik Kaszewski16-63/+617
[Why] HDCP locality check has strict timing requirements, currently broken due to reliance on msleep which does not guarantee accuracy. The PR moves the write-poll-read sequence into DMUB using new generic Fused IO interface, where the timing accuracy is greatly improved. New flow is enabled using DCN resource capability bit (none for now), or using a debug flag. [How] * Extended mod_hdcp_config with new function for requesting DMUB to execute a sequence of fused I2C/AUX commands and synchronously wait until an outbox reply arrives or a timeout expires. * If the timeout expires, send an abort to DMUB. * Update HDCP to use the DMUB for locality check if supported. * Add DC_HDCP_LC_FORCE_FW_ENABLE and DC_HDCP_LC_ENABLE_SW_FALLBACK. * Make the first enable new flow regardless of resource capabilities. * Make the second enable fallback to old SW flow. * Clean up makefile source file listings for easier updates.

2025-04-08drm/amd/display: Correct SSC enable detection for DCN351Kevin Gao3-2/+10
[Why] Due to very small clock register delta between DCN35 and DCN351, clock spread is being checked on the wrong register for DCN351, causing the display driver to believe that DPREFCLK downspread to be disabled when in some stacks it is enabled. This causes the clock values for audio to be incorrect. [How] Both DCN351 and DCN35 use the same clk_mgr, so we modify the DCN35 function that checks for SSC enable to read CLK6 instead of CLK5 when using DCN351. This allows us to read for DPREFCLK downspread correctly so the clock can properly compensate when setting values.

The "higher" values are "slower" to drag around. [How] Move custom brightness calculation loop into a static function.
