drm/amd: Align SMU11 SMU_MSG_OverridePcieParameters implementation with SMU13

2023-07-12T16:21:23+00:00

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

2023-07-12T16:09:54+00:00

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

2023-07-12T16:08:17+00:00

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.

drm/amdgpu: avoid restore process run into dead loop.

In restore process worker, pinned BO cause update PTE fail, then
the function re-schedule the restore_work. This will generate dead loop.

fence Decrements the reference count before exiting.
Avoid Race Vulnerabilities for fence use-after-free.

v2 (chk): actually fix the use after free and not just move it.

drm/amd/pm: avoid unintentional shutdown due to temperature momentary fluctuation

2023-06-30T17:12:16+00:00

An intentional delay is added on soft ctf triggered. Then there will
be a double check for the GPU temperature before taking further
action. This can avoid unintended shutdown due to temperature
momentary fluctuation.
