In function si_parse_power_table(), array adev->pm.dpm.ps and its member is allocated. If the allocation of each member fails, the array itself is freed and returned with an error code. However, the array is later freed again in si_dpm_fini() function which is called when the function returns an error. This leads to potential double free of the array adev->pm.dpm.ps, as well as leak of its array members, since the members are not freed in the allocation function and the array is not nulled when freed. In addition adev->pm.dpm.num_ps, which keeps track of the allocated array member, is not updated until the member allocation is successfully finished, this could also lead to either use after free, or uninitialized variable access in si_dpm_fini(). Fix this by postponing the free of the array until si_dpm_fini() and increment adev->pm.dpm.num_ps everytime the array member is allocated. Signed-off-by:

Clarify the smu_cmn_send_smc_msg_with_param documentation to mention two cases exist where messages are silently dropped with no error returned. These cases occur in unusual situations where either: 1. the message type is not allowed to a virtual GPU, or 2. a PCI recovery is underway and the HW is not yet in sync with the SW For more details see commit 4ea5081c ("drm/amd/powerplay: enable SMC message filter") commit bf36b52e ("drm/amdgpu: Avoid accessing HW when suspending SW state") (v2) Reworked with suggestions from Luben & Paul (v3) Updated wording as per Luben's feedback Corrected error stating all messages denied on virtual GPU (each GPU has mask of which messages are allowed) Signed-off-by:

This reverts commit 863fa85e. While we were testing DCN3.1 with a hub, we noticed that only one of 2 connected displays lights up when using some specific display resolution. In summary, this was the setup: 1. Displays: * Sharp LQ156M1JW26 (eDP): 1080@240 * BENQ SW320 (DP): 4k@60 * BENQ EX3203R (DP): 4k@60 2. Hub: Club3D CSV-7300 3. ASIC: DCN3.1 After bisecting this issue, we figured out the commit mentioned above introduced this issue. We are investigating why this patch introduced this regression, but we need to revert it for now.

Currently, the IO-links to the device being removed from topology, are not cleared. As a result, there would be dangling links left in the KFD topology. This patch aims to fix the following: 1. Cleanup all IO links to the device being removed. 2. Ensure that node numbering in sysfs and nodes proximity domain values are consistent after the device is removed: a. Adding a device and removing a GPU device are made mutually exclusive. b. The global proximity domain counter is no longer required to be an atomic counter. A normal 32-bit counter can be used instead. 3. Update generation_count to let user-mode know that topology has changed due to device removal.
