drm/amd: Align SMU11 SMU_MSG_OverridePcieParameters implementation with SMU13

2023-08-03T08:23:47+00:00

commit e701156ccc6c7a5f104a968dda74cd6434178712 upstream. SMU13 overrides dynamic PCIe lane width and dynamic speed by when on certain hosts. commit 38e4ced80479 ("drm/amd/pm: conditionally disable pcie lane switching for some sienna_cichlid SKUs") worked around this issue by setting up certain SKUs to set up certain limits, but the same fundamental problem with those hosts affects all SMU11 implmentations as well, so align the SMU11 and SMU13 driver handling.

drm/amd: Move helper for dynamic speed switch check out of smu13

2023-08-03T08:23:47+00:00

commit 188623076d0f1a500583d392b6187056bf7cc71a upstream. This helper is used for checking if the connected host supports the feature, it can be moved into generic code to be used by other smu implementations as well.

drm/amd/pm: conditionally disable pcie lane/speed switching for SMU13

2023-07-23T11:49:45+00:00

commit 31c7a3b378a136adc63296a2ff17645896fcf303 upstream. Intel platforms such as Sapphire Rapids and Raptor Lake don't support dynamic pcie lane or speed switching. This limitation seems to carry over from one generation to another. To be safer, disable dynamic pcie lane width and speed switching when running on an Intel platform.
