2021-05-11drm/amd/pm: Fix out-of-bounds bugGustavo A. R. Silva2-99/+109
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.

2021-05-11drm/amdgpu: Rename to ras_*_enabledLuben Tuikov2-2/+2
Rename, ras_hw_supported --> ras_hw_enabled, and ras_features --> ras_enabled, to show that ras_enabled is a subset of ras_hw_enabled, which itself is a subset of the ASIC capability.

2021-05-11drm/amdgpu: Remove redundant ras->supportedLuben Tuikov2-2/+3
Remove redundant ras->supported, as this value is also stored in adev->ras_features. Use adev->ras_features, as that supercedes "ras", since the latter is its member. The dependency goes like this: ras <== adev->ras_features <== hw_supported, and is read as "ras depends on ras_features, which depends on hw_supported." The arrows show the flow of information, i.e. the dependency update. "hw_supported" should also live in "adev".
