2021-08-05drm/amd/display: workaround for hard hang on HPD on native DPQingqing Zhuo1-1/+3
[Why] HPD disable and enable sequences are not mutually exclusive on Linux. For HPDs that spans over 1s (i.e. HPD low = 1s), part of the disable sequence (specifically, a request to SMU to lower refclk) could come right before the call to PHY enable, causing DMUB to access an unresponsive PHY and thus a hard hang on the system. [How] Disable 48mhz refclk off on native DP.

2021-08-02drm/amdgpu: Fix out-of-bounds read when update mappingxinhui pan1-1/+2
If one GTT BO has been evicted/swapped out, it should sit in CPU domain. TTM only alloc struct ttm_resource instead of struct ttm_range_mgr_node for sysMem. Now when we update mapping for such invalidated BOs, we might walk out of bounds of struct ttm_resource. Three possible fix: 1) Let sysMem manager alloc struct ttm_range_mgr_node, like ttm_range_manager does. 2) Pass pages_addr to update_mapping function too, but need memset pages_addr[] to zero when unpopulate. 3) Init amdgpu_res_cursor directly. bug is detected by kfence. ================================================================== BUG: KFENCE: out-of-bounds read in amdgpu_vm_bo_update_mapping+0x564/0x6e0 Out-of-bounds read at 0x000000008ea93fe9 (64B right of kfence-#167): amdgpu_vm_bo_update_mapping+0x564/0x6e0 [amdgpu] amdgpu_vm_bo_update+0x282/0xa40 [amdgpu] amdgpu_vm_handle_moved+0x19e/0x1f0 [amdgpu] amdgpu_cs_vm_handling+0x4e4/0x640 [amdgpu] amdgpu_cs_ioctl+0x19e7/0x23c0 [amdgpu] drm_ioctl_kernel+0xf3/0x180 [drm] drm_ioctl+0x2cb/0x550 [drm] amdgpu_drm_ioctl+0x5e/0xb0 [amdgpu] kfence-#167 [0x000000008e11c055-0x000000001f676b3e ttm_sys_man_alloc+0x35/0x80 [ttm] ttm_resource_alloc+0x39/0x50 [ttm] ttm_bo_swapout+0x252/0x5a0 [ttm] ttm_device_swapout+0x107/0x180 [ttm] ttm_global_swapout+0x6f/0x130 [ttm] ttm_tt_populate+0xb1/0x2a0 [ttm] ttm_bo_handle_move_mem+0x17e/0x1d0 [ttm] ttm_mem_evict_first+0x59d/0x9c0 [ttm] ttm_bo_mem_space+0x39f/0x400 [ttm] ttm_bo_validate+0x13c/0x340 [ttm] ttm_bo_init_reserved+0x269/0x540 [ttm] amdgpu_bo_create+0x1d1/0xa30 [amdgpu] amdgpu_bo_create_user+0x40/0x80 [amdgpu] amdgpu_gem_object_create+0x71/0xc0 [amdgpu] amdgpu_amdkfd_gpuvm_alloc_memory_of_gpu+0x2f2/0xcd0 [amdgpu] kfd_ioctl_alloc_memory_of_gpu+0xe2/0x330 [amdgpu] kfd_ioctl+0x461/0x690 [amdgpu] Signed-off-by: xinhui pan <[email protected]> Reviewed-by: Christian König <[email protected]> Signed-off-by: Alex Deucher <[email protected]>

2021-07-28drm/amd/display: add update authentication interfaceWenjing Liu2-6/+69
[why] Previously to toggle authentication, we need to remove and add the same display back with modified adjustment. This method will toggle DTM state without actual hardware changes. This is not per design and would cause potential issues in the long run. [how] We are creating a dedicated interface that does the same thing as remove and add back the display without changing DTM state.

2021-07-27drm/amdgpu/display: only enable aux backlight control for OLED panelsAlex Deucher1-2/+2
We've gotten a number of reports about backlight control not working on panels which indicate that they use aux backlight control. A recent patch: commit 2d73eabe2984a435737498ab39bb1500a9ffe9a9 Author: Camille Cho <[email protected]> Date: Thu Jul 8 18:28:37 2021 +0800 drm/amd/display: Only set default brightness for OLED [Why] We used to unconditionally set backlight path as AUX for panels capable of backlight adjustment via DPCD in set default brightness. [How] This should be limited to OLED panel only since we control backlight via PWM path for SDR mode in LCD HDR panel. Reviewed-by: Krunoslav Kovac <[email protected]> Acked-by: Rodrigo Siqueira <[email protected]> Signed-off-by: Camille Cho <[email protected]> Signed-off-by: Alex Deucher <[email protected]> Changes some other code to only use aux for backlight control on OLED panels. The commit message seems to indicate that PWM should be used for SDR mode on HDR panels. Do something similar for backlight control in general. This may need to be revisited if and when HDR started to get used.

[Why] We don't check DENTIST_DISPCLK_CHG_DONE to ensure dentist display clockis updated to target value. In some scenarios with large display clock margin, it will deliver unfinished display clock and cause issues like display black screen. [How] Checking DENTIST_DISPCLK_CHG_DONE to ensure display clock has been update to target value before driver do other clock related actions.
