2021-05-19drm/radeon/dpm: Disable sclk switching on Oland when two 4K 60Hz monitors ↵Kai-Heng Feng
are connected Screen flickers rapidly when two 4K 60Hz monitors are in use. This issue doesn't happen when one monitor is 4K 60Hz (pixelclock 594MHz) and another one is 4K 30Hz (pixelclock 297MHz). The issue is gone after setting "power_dpm_force_performance_level" to "high". Following the indication, we found that the issue occurs when sclk is too low.

2021-05-10drm/amd/pm: Fix out-of-bounds bugGustavo A. R. Silva
Create new structure SISLANDS_SMC_SWSTATE_SINGLE, as initialState.levels and ACPIState.levels are never actually used as flexible arrays. Those arrays can be used as simple objects of type SISLANDS_SMC_HW_PERFORMANCE_LEVEL, instead. Currently, the code fails because flexible array _levels_ in struct SISLANDS_SMC_SWSTATE doesn't allow for code that accesses the first element of initialState.levels and ACPIState.levels arrays: drivers/gpu/drm/amd/pm/powerplay/si_dpm.c: 4820: table->initialState.levels[0].mclk.vDLL_CNTL = 4821: cpu_to_be32(si_pi->clock_registers.dll_cntl); ... 5021: table->ACPIState.levels[0].mclk.vDLL_CNTL = 5022: cpu_to_be32(dll_cntl); because such element cannot be accessed without previously allocating enough dynamic memory for it to exist (which never actually happens). So, there is an out-of-bounds bug in this case. That's why struct SISLANDS_SMC_SWSTATE should only be used as type for object driverState and new struct SISLANDS_SMC_SWSTATE_SINGLE is created as type for objects initialState, ACPIState and ULVState. Also, with the change from one-element array to flexible-array member in commit 0e1aa13ca3ff ("drm/amd/pm: Replace one-element array with flexible-array in struct SISLANDS_SMC_SWSTATE"), the size of dpmLevels in struct SISLANDS_SMC_STATETABLE should be fixed to be SISLANDS_MAX_SMC_PERFORMANCE_LEVELS_PER_SWSTATE instead of SISLANDS_MAX_SMC_PERFORMANCE_LEVELS_PER_SWSTATE - 1.

2021-05-10drm/amd/display: Add fallback and abort paths for DP link training.Jimmy Kizito
[Why] When enabling a DisplayPort stream: - Optionally reducing link bandwidth between failed link training attempts should progressively relax training requirements. - Abandoning link training altogether if a sink is unplugged should avoid unnecessary training attempts. [How] - Add fallback parameter to DP link training function and reduce link bandwidth between failed training attempts as long as stream bandwidth requirements are met. - Add training status for sink unplug and abort training when this status is reported.
