[Why] We can override SR watermarks but not Z8 ones. [How] Add new parameters for Z8 matching the SR ones and feed them into the states. These also weren't being applied to every state, so make sure that we loop over and update all SOC states if given an override. Reviewed-by:

The smu needs to get the rlc power down message to sync the rlc state with smu, the rlc state updating message need to be sent at while smu begin suspend sequence , otherwise SMU will crash while RLC state is not notified by driver, and rlc state probally changed after that notification, so it needs to notify rlc state to smu at the end of the suspend sequence in amdgpu_device_suspend() that can make sure the rlc state is correctly set to SMU.

[why] In dcn32 DML pipes are ordered the same as dc pipes but only for used pipes. For example, if dc pipe 1 and 2 are used, their dml pipe indices would be 0 and 1 respectively. However update_pipe_slice_table_with_split_flags doesn't skip indices for free pipes. This causes us to not reference correct dml pipe output when building pipe topology. [how] Use two variables to iterate dc and dml pipes respectively and only increment dml pipe index when current dc pipe is not free. Cc: stable@vger.kernel.org # 6.1+ Reviewed-by:

By catting the xgmi_port_num sysfs node, it prints out the info in the format of <src node id>:<src port num> -> <dst node id>:<dst port num> for one xgmi link. For example, in case of 4 sockets fully and evenly connected setup, it would be like as below for the first node in the hive. 01:02 -> 02:03 01:03 -> 02:02 01:07 -> 03:04 01:04 -> 03:07 01:06 -> 04:05 01:05 -> 04:06 Based on the fact that there is two xgmi links between each socket pair, "01:02 -> 02:03" means that the current socket in question use the port 2 to connect with port 3 of the second node in the hive and so on. v2: print out the src/dst node id for each xgmi link (lijo) v3: replace the current_node++ with +1 to align with dst node (le) and use the dev_err instead of pr_err (lijo) v4: fix checkpatch warning (alex) Signed-off-by:Shiwu Zhang <shiwu.zhang@amd.com> Acked-by:

The PCIe speed capabilities advertised by a USB4 or TBT3 link are limited to PCIe gen 1 per the USB4 spec. In reality the speed will change dynamically based on fabric conditions and other traffic. DPM is disabled when dGPUs are connected directly to Intel hosts since the PCIe root port isn't able to handle dynamic speed switching. As this limitation is specifically for PCIe root ports in the SoC, don't apply it when connected to an eGPU enclosure connected to an Intel host.

When bandwidth limits are looked up using pcie_bandwidth_available() virtual links such as USB4 are analyzed which might not represent the real speed. Furthermore devices may change speeds autonomously which may introduce conditional variation to the results reported in the status registers. Instead look at the capabilities of first PCI device outside of dGPU to decide upper limits that the dGPU will work at. For eGPU this effectively means that it will use the speed of the link partner.

For features that are implemented primarily in DMUB (e.g. PSR), it is useful to be able to trace them at a DMUB level from the kernel, especially when debugging issues. So, introduce a debugfs interface that is able to read and set the DMUB trace mask dynamically at runtime and document how to use it.
