2024-02-22drm/amd/display: Fix potential null pointer dereference in dc_dmub_srvSrinivasan Shanmugam1-2/+5
Fixes potential null pointer dereference warnings in the dc_dmub_srv_cmd_list_queue_execute() and dc_dmub_srv_is_hw_pwr_up() functions. In both functions, the 'dc_dmub_srv' variable was being dereferenced before it was checked for null. This could lead to a null pointer dereference if 'dc_dmub_srv' is null. The fix is to check if 'dc_dmub_srv' is null before dereferencing it. Thus moving the null checks for 'dc_dmub_srv' to the beginning of the functions to ensure that 'dc_dmub_srv' is not null when it is dereferenced. Found by smatch & thus fixing the below: drivers/gpu/drm/amd/amdgpu/../display/dc/dc_dmub_srv.c:133 dc_dmub_srv_cmd_list_queue_execute() warn: variable dereferenced before check 'dc_dmub_srv' (see line 128) drivers/gpu/drm/amd/amdgpu/../display/dc/dc_dmub_srv.c:1167 dc_dmub_srv_is_hw_pwr_up() warn: variable dereferenced before check 'dc_dmub_srv' (see line 1164) Fixes: 028bac583449 ("drm/amd/display: decouple dmcub execution to reduce lock granularity") Fixes: 65138eb72e1f ("drm/amd/display: Add DCN35 DMUB") Cc: JinZe.Xu <[email protected]> Cc: Hersen Wu <[email protected]> Cc: Josip Pavic <[email protected]> Cc: Roman Li <[email protected]> Cc: Qingqing Zhuo <[email protected]> Cc: Harry Wentland <[email protected]> Cc: Rodrigo Siqueira <[email protected]> Cc: Aurabindo Pillai <[email protected]> Cc: Tom Chung <[email protected]> Signed-off-by: Srinivasan Shanmugam <[email protected]> Reviewed-by: Tom Chung <[email protected]> Signed-off-by: Alex Deucher <[email protected]>

2024-02-16drm/amdkfd: Relocate TBA/TMA to opposite side of VM holeFelix Kuehling4-22/+27
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 <[email protected]> Cc: Christian Koenig <[email protected]> Reviewed-by: Christian König <[email protected]> Signed-off-by: Jay Cornwall <[email protected]> Signed-off-by: Felix Kuehling <[email protected]> Signed-off-by: Alex Deucher <[email protected]>

2024-02-14drm/amd/display: Update FIXED_VS Retimer HWSS Test Pattern SequencesMichael Strauss6-56/+65
[WHY] Need to fix some broken logic and sequencing in initial commit [HOW] Fix logic handling override deprogramming when exiting SQ128. Don't exit early from dp_set_hw_lane_settings for DP2/FIXED_VS case. Move LTTPR 128b/132b check out of requires_hwss and check during runtime, as LTTPR caps are not populated on initial call. Add pending_test_pattern to link state to allow HWSS to set FFE overrides on retimer TX and/or skip setting APU TX FFE depending on requested pattern. Use updated clock source for SQ128 override sequence. Skip HW FFE preset programming when performing test pattern overrides.
