why: Need interface to lower clocks when in dc (power save) mode. Must be able to work with p_state unsupported cases Can cause flicker when OS notifies us of dc state change how: added dal3 interface for KMD added pathway to query smu for this softmax added blank before clock change to override underflow added logic to change clk based on pstatesupport and softmax added logic in prepare/optimize_bw to conform while changing clocks Reviewed-by:

[Why] SMU now respects the PHY refclk disable request from driver. This causes a hang during hotplug when PHY refclk was disabled because it's not being re-enabled and the transmitter control starts on dc_link_detect. [How] We normally would re-enable the clk with exit_optimized_pwr_state but this is only set on DCN21 and DCN301. Set it for dcn31 as well. This fixes DMCUB timeouts in the PHY.

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.

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:
