drm/amdgpu: Fix usage of UMC fill record in RAS

2023-07-19T14:21:32+00:00

[ Upstream commit 71344a718a9fda8c551cdc4381d354f9a9907f6f ] The fixed commit listed in the Fixes tag below, introduced a bug in amdgpu_ras.c::amdgpu_reserve_page_direct(), in that when introducing the new amdgpu_umc_fill_error_record() and internally in that new function the physical address (argument "uint64_t retired_page"--wrong name) is right-shifted by AMDGPU_GPU_PAGE_SHIFT. Thus, in amdgpu_reserve_page_direct() when we pass "address" to that new function, we should NOT right-shift it, since this results, erroneously, in the page address to be 0 for first 2^(2*AMDGPU_GPU_PAGE_SHIFT) memory addresses. This commit fixes this bug.

This reverts commit dac6b80818ac2353631c5a33d140d8d5508e2957. This commit reverted the AMDGPU_SKIP_MODE2_RESET as it conflicts with the original design of reset handler. Will redesign it.

drm/amdgpu: Fixed ras warning when uninstalling amdgpu

2022-09-29T13:41:42+00:00

For the asic using smu v13_0_2, there is the following warning when uninstalling amdgpu: amdgpu: ras disable gfx failed poison:1 ret:-22. [Why]: For the asic using smu v13_0_2, the psp .suspend and mode1reset is called before amdgpu_ras_pre_fini during amdgpu uninstall, it has disabled all ras features and reset the psp. Since the psp is reset, calling amdgpu_ras_disable_all_features in amdgpu_ras_pre_fini to disable ras features will fail. [How]: If all ras features are disabled, amdgpu_ras_disable_all_features will not be called to disable all ras features again.
