drm/amd: Fix shutdown (again) on some SMU v13.0.4/11 platforms

commit 267cace556e8a53d703119f7435ab556209e5b6a upstream. commit cd94d1b182d2 ("dm/amd/pm: Fix problems with reboot/shutdown for some SMU 13.0.4/13.0.11 users") attempted to fix shutdown issues that were reported since commit 31729e8c21ec ("drm/amd/pm: fixes a random hang in S4 for SMU v13.0.4/11") but caused issues for some people. Adjust the workaround flow to properly only apply in the S4 case: -> For shutdown go through SMU_MSG_PrepareMp1ForUnload -> For S4 go through SMU_MSG_GfxDeviceDriverReset and SMU_MSG_PrepareMp1ForUnload Reported-and-tested-by: lectrode Closes: https://github.com/void-linux/void-packages/issues/50417 Cc: stable@vger.kernel.org Fixes: cd94d1b182d2 ("dm/amd/pm: Fix problems with reboot/shutdown for some SMU 13.0.4/13.0.11 users") Reviewed-by: Tim Huang Signed-off-by: Mario Limonciello Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman

drm/amd/pm: Restore config space after reset

2024-06-12T09:11:23+00:00

[ Upstream commit 30d1cda8ce31ab49051ff7159280c542a738b23d ] During mode-2 reset, pci config space registers are affected at device side. However, certain platforms have switches which assign virtual BAR addresses and returns the same even after device is reset. This affects pci_restore_state() as it doesn't issue another config write, if the value read is same as the saved value. Add a workaround to write saved config space values from driver side. Presently, these switches are in platforms with SMU v13.0.6 SOCs, hence restrict the workaround only to those.

drm/amd/pm: fixes a random hang in S4 for SMU v13.0.4/11

2024-04-17T09:19:25+00:00

commit 31729e8c21ecfd671458e02b6511eb68c2225113 upstream. While doing multiple S4 stress tests, GC/RLC/PMFW get into an invalid state resulting into hard hangs. Adding a GFX reset as workaround just before sending the MP1_UNLOAD message avoids this failure.
