[Why] When HPD IRQ occurs, it triggers a PSR disable and reenable directly through dc layer. Since it does not pass through the power layer, the layer that tracks whether PSR is enabled or disabled and which masks are set, this layer is now out of sync with the real PSR state in FW. Theoretically PSR can be enabled during hw programming sequences or any other situation where we must disable PSR. [How] Check if PSR is enabled before doing PSR disable/reenable. Reviewed-by:

[Why] The HW interrupt gets disabled after S3/S4/reset so we don't receive notifications for HPD or AUX from DMUB - leading to timeout and black screen with (or without) DPIA links connected. [How] Re-enable the interrupt after S3/S4/reset like we do for the other DC interrupts. Guard both instances of the outbox interrupt enable or we'll hang during restore on ASIC that don't support it.

In radeon_driver_open_kms(), radeon_vm_bo_add() is assigned to vm->ib_bo_va and passes and used in radeon_vm_bo_set_addr(). In radeon_vm_bo_set_addr(), there is a dereference of vm->ib_bo_va, which could lead to a NULL pointer dereference on failure of radeon_vm_bo_add(). Fix this bug by adding a check of vm->ib_bo_va. This bug was found by a static analyzer. The analysis employs differential checking to identify inconsistent security operations (e.g., checks or kfrees) between two code paths and confirms that the inconsistent operations are not recovered in the current function or the callers, so they constitute bugs. Note that, as a bug found by static analysis, it can be a false positive or hard to trigger. Multiple researchers have cross-reviewed the bug. Builds with CONFIG_DRM_RADEON=m show no new warnings, and our static analyzer no longer warns about this code. Fixes: cc9e67e3 ("drm/radeon: fix VM IB handling") Reviewed-by:

dm_check_crtc_cursor() doesn't take into account plane transforms when calculating plane scaling, this can result in false positives. For example, if there's an output with resolution 3840x2160 and the output is rotated 90 degrees, CRTC_W and CRTC_H will be 3840 and 2160, respectively, but SRC_W and SRC_H will be 2160 and 3840, respectively. Since the cursor plane usually has a square buffer attached to it, the dm_check_crtc_cursor() will think that there's a scale factor mismatch even though there isn't really. This fixes an issue where kwin fails to use hardware plane transforms. Changes since version 1: - s/orientated/oriented/g Reviewed-by:

amdgpu_ucode_get_load_type() does not interpret this parameter as documented. It is ignored for many ASIC types (which presumably only support one load_type), and when not ignored it is only used to force direct loading instead of PSP loading. SMU loading is only available for ASICs for which the parameter is ignored. Signed-off-by:
