Memory used by KFD applications can contain sensitive information that should not be leaked to other processes. The current approach to prevent leaks is to clear VRAM at allocation time. This is not effective because memory can be reused in other ways without being cleared. Synchronously clearing memory on the allocation path also carries a significant performance penalty. Stop clearing memory at allocation time. Instead mark the memory for wipe on release. Signed-off-by:

Wipe VRAM memory containing sensitive data when moving or releasing BOs. Clearing the memory is pipelined to minimize any impact on subsequent memory allocation latency. Use of a poison value should help debug future use-after-free bugs. When moving BOs, the existing ttm_bo_pipelined_move ensures that the memory won't be reused before being wiped. When releasing BOs, the BO is fenced with the memory fill operation, which results in queuing the BO for a delayed delete. v2: Move amdgpu_amdkfd_unreserve_memory_limit into amdgpu_bo_release_notify so that KFD can use memory that's still being cleared in the background Signed-off-by:

This memory allocation flag will be used to indicate BOs containing sensitive data that should not be leaked to other processes. Signed-off-by:
-
Felix Kuehling authored
This notifies the driver that a BO is about to be released. Releasing a BO also invokes the move_notify callback from ttm_bo_cleanup_memtype_use, but that happens too late for anything that would add fences to the BO and require a delayed delete. Signed-off-by:

Using a static int array will cause errors if the given dm_pp_clk_type is out-of-bounds. For robustness, use a switch table, with a default case to handle all invalid values. v2: 0 is a valid clock type for smu_clk_type. Return SMU_CLK_COUNT instead on invalid mapping.

previously the ucode loading of PSP was repreated, one executed in phase_1 init/re-init/resume and the other in fw_loading routine Avoid this double loading by clearing ip_blocks.status.hw in suspend or reset prior to the FW loading and any block's hw_init/resume v2: still do the smu fw loading since it is needed by bare-metal v3: drop the change in reinit_early_sriov, just clear all block's status.hw in the head place and set the status.hw after hw_init done is enough Signed-off-by:

we can simplify all those unnecessary function under SRIOV for vega10 since: 1) PSP L1 policy is by force enabled in SRIOV 2) original logic always set all flags which make itself a dummy step besides, 1) the ih_doorbell_range set should also be skipped for VEGA10 SRIOV. 2) the gfx_common registers should also be skipped for VEGA10 SRIOV.
