2021-12-13drm/amdgpu: add support for SMU debug optionLang Yu3-1/+33
SMU firmware expects the driver maintains error context and doesn't interact with SMU any more when SMU errors occurred. That will aid in debugging SMU firmware issues. Add SMU debug option support for this request, it can be enabled or disabled via amdgpu_smu_debug debugfs file. Use a 32-bit mask to indicate corresponding debug modes. Currently, only one mode(HALT_ON_ERROR) is supported. When enabled, it brings hardware to a kind of halt state so that no one can touch it any more in the envent of SMU errors. The dirver interacts with SMU via sending messages. And threre are three ways to sending messages to SMU in current implementation. Handle them respectively as following: 1, smu_cmn_send_smc_msg_with_param() for normal timeout cases Halt on any error. 2, smu_cmn_send_msg_without_waiting()/smu_cmn_wait_for_response() for longer timeout cases Halt on errors apart from ETIME. Otherwise this way won't work. Let the user handle ETIME error in such a case. 3, smu_cmn_send_msg_without_waiting() for no waiting cases Halt on errors apart from ETIME. Otherwise second way won't work. == Command Guide == 1, enable HALT_ON_ERROR mode # echo 0x1 > /sys/kernel/debug/dri/0/amdgpu_smu_debug 2, disable HALT_ON_ERROR mode # echo 0x0 > /sys/kernel/debug/dri/0/amdgpu_smu_debug v5: - Use bit mask to allow more debug features.(Evan) - Use WRAN() instead of BUG().(Evan) v4: - Set to halt state instead of a simple hang.(Christian) v3: - Use debugfs_create_bool().(Christian) - Put variable into smu_context struct. - Don't resend command when timeout. v2: - Resend command when timeout.(Lijo) - Use debugfs file instead of module parameter.

2021-12-13drm/amdgpu: introduce a kind of halt state for amdgpu deviceLang Yu2-0/+41
It is useful to maintain error context when debugging SW/FW issues. Introduce amdgpu_device_halt() for this purpose. It will bring hardware to a kind of halt state, so that no one can touch it any more. Compare to a simple hang, the system will keep stable at least for SSH access. Then it should be trivial to inspect the hardware state and see what's going on. v2: - Set adev->no_hw_access earlier to avoid potential crashes.(Christian) Suggested-by: Christian Koenig <christian.koenig@amd.com> Suggested-by: Andrey Grodzovsky <andrey.grodzovsky@amd.com> Signed-off-by: Lang Yu <lang.yu@amd.com> Reviewed-by: Christian Koenig <christian.koenig@amd.co> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2021-12-13drm/amdkfd: Fix svm_range_is_same_attrsFelix Kuehling1-11/+56
The existing function doesn't compare the access bitmaps and flags. This can result in failure to update those attributes in existing ranges when all other attributes remained unchanged. Because the access and flags attributes modify only some bits in the respective bitmaps, we cannot compare them directly. Instead we need to check whether applying the attributes to a particular range would change the bitmaps. A PREFETCH_LOC attribute must always trigger a migration, even if the attribute value remains unchanged. E.g. if some pages were migrated due to a CPU page fault, a prefetch must still be executed to migrate pages back to VRAM.
