In the first if statement, we're checking if 'replay' is NULL. But in the second if statement, we're not checking if 'replay' is NULL again before calling replay->funcs->replay_set_power_opt(). if (replay == NULL && force_static) return false; ... if (link->replay_settings.replay_feature_enabled && replay->funcs->replay_set_power_opt) { replay->funcs->replay_set_power_opt(replay, *power_opts, panel_inst); link->replay_settings.replay_power_opt_active = *power_opts; } If 'replay' is NULL, this will cause a null pointer dereference.

The TBA and TMA, along with an unused IB allocation, reside at low addresses in the VM address space. A stray VM fault which hits these pages must be serviced by making their page table entries invalid. The scheduler depends upon these pages being resident and fails, preventing a debugger from inspecting the failure state. By relocating these pages above 47 bits in the VM address space they can only be reached when bits [63:48] are set to 1. This makes it much less likely for a misbehaving program to generate accesses to them. The current placement at VA (PAGE_SIZE*2) is readily hit by a NULL access with a small offset. v2: - Move it to the reserved space to avoid concflicts with Mesa - Add macros to make reserved space management easier v3: - Move VM max PFN calculation into AMDGPU_VA_RESERVED macros Cc: Arunpravin Paneer Selvam <Arunpravin.PaneerSelvam@amd.com> Cc: Christian Koenig <christian.koenig@amd.com> Reviewed-by:

The reservation is there to catch NULL pointer dereferences from the GPU. Reduce the size to 64KB to make sure that shared virtual address programming models can map all CPU-accessible virtual addresses for GPU access.

The dcn30_get_gamcor_current() function is responsible for determining the current gamma correction mode used by the display controller. However, the 'mode' variable, which stores the gamma correction mode, was not initialized before its first usage, leading to an uninitialized symbol error. Thus initializes the 'mode' variable with a default value of LUT_BYPASS before the conditional statements in the function, improves code clarity and stability, ensuring correct behavior of the dcn30_get_gamcor_current() function in determining the gamma correction mode. Fixes the below: drivers/gpu/drm/amd/amdgpu/../display/dc/dcn30/dcn30_dpp_cm.c:77 dpp30_get_gamcor_current() error: uninitialized symbol 'mode'.
