drm/amdgpu: fix check in gmc_v9_0_get_vm_pte()

2024-11-11T19:05:44Z

The coherency flags can only be determined when the BO is locked and that in turn is only guaranteed when the mapping is validated. Fix the check, move the resource check into the function and add an assert that the BO is locked.

drm/amdgpu: prevent NULL pointer dereference if ATIF is not supported

2024-11-04T17:48:21Z

acpi_evaluate_object() may return AE_NOT_FOUND (failure), which would result in dereferencing buffer.pointer (obj) while being NULL. Although this case may be unrealistic for the current code, it is still better to protect against possible bugs. Bail out also when status is AE_NOT_FOUND.
