Re-revert "drm/amd/display: Enable Replay for static screen use cases"

2024-02-05T20:14:30+00:00

[ Upstream commit d6398866a6b47e92319ef6efdb0126a4fbb7796a ] This reverts commit 44e60b14d5a72f91fd0bdeae8da59ae37a3ca8e5. Since, it causes a regression in which eDP displays with PSR support, but no Replay support (Sink support <= 0x03), fail to enable PSR and consequently all IGT amd_psr tests fail. So, revert this until a more suitable fix can be found. This got brought back accidently with the backmerge.

drm/amdkfd: fix mes set shader debugger process management

2024-02-05T20:14:28+00:00

[ Upstream commit bd33bb1409b494558a2935f7bbc7842def957fcd ] MES provides the driver a call to explicitly flush stale process memory within the MES to avoid a race condition that results in a fatal memory violation. When SET_SHADER_DEBUGGER is called, the driver passes a memory address that represents a process context address MES uses to keep track of future per-process calls. Normally, MES will purge its process context list when the last queue has been removed. The driver, however, can call SET_SHADER_DEBUGGER regardless of whether a queue has been added or not. If SET_SHADER_DEBUGGER has been called with no queues as the last call prior to process termination, the passed process context address will still reside within MES. On a new process call to SET_SHADER_DEBUGGER, the driver may end up passing an identical process context address value (based on per-process gpu memory address) to MES but is now pointing to a new allocated buffer object during KFD process creation. Since the MES is unaware of this, access of the passed address points to the stale object within MES and triggers a fatal memory violation. The solution is for KFD to explicitly flush the process context address from MES on process termination. Note that the flush call and the MES debugger calls use the same MES interface but are separated as KFD calls to avoid conflicting with each other.

Currently, we store CU info only for a single XCC assuming that it is the same for all XCCs. However, that may not be true. As a result, store CU info for all XCCs. This info is later used for CU masking. Signed-off-by: Mukul Joshi Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdkfd: Fix reg offset for setting CWSR grace period

2023-09-11T22:15:43+00:00

This patch fixes the case where the code currently passes absolute register address and not the reg offset, which HWS expects, when sending the PM4 packet to set/update CWSR grace period. Additionally, cleanup the signature of build_grace_period_packet_info function as it no longer needs the inst parameter.
