[Why] We'll exit optimized power state to do link detection but we won't enter back into the optimized power state. This could potentially block s2idle entry depending on the sequencing, but it also means we're losing some power during the transition period. [How] Hook up the handler like DCN21. It was also missed like the exit_optimized_pwr_state callback. Fixes: 64b1d0e8 ("drm/amd/display: Add DCN3.1 HWSEQ") Tested-by:

[Why] Stutter period won't be less than 5000.0, but if PSR is enabled then we can potentially enter Z9 when MPO is enabled. SMU will try to enter Z9 too early in these cases (before PSR is enabled) and we'll see underflow. [How] Block z-states (z9, z10) until we can add a new interface to SMU to signal when we can support z10 but not z9. We can revert this once the interface change is in. Tested-by:

If the event guard is enabled and VF doesn't receive an ack from PF for full access, the guest driver load crashes. This is caused due to the call to ttm_device_clear_dma_mappings with non-initialized mman during driver tear down. This patch adds the necessary condition to check if the mman initialization passed or not and takes the path based on the condition output. Signed-off-by:

drm/amdgpu: Call amdgpu_device_unmap_mmio() if device is unplugged to prevent crash in GPU initialization failure [Why] In amdgpu_driver_load_kms, when amdgpu_device_init returns error during driver modprobe, it will start the error handle path immediately and call into amdgpu_device_unmap_mmio as well to release mapped VRAM. However, in the following release callback, driver stills visits the unmapped memory like vcn.inst[i].fw_shared_cpu_addr in vcn_v3_0_sw_fini. So a kernel crash occurs. [How] call amdgpu_device_unmap_mmio() if device is unplugged to prevent invalid memory address in vcn_v3_0_sw_fini() when GPU initialization failure. Signed-off-by:

[Why] A porting error on a previous patch left the block of code that causes the crash from a NULL pointer dereference. More specifically, we try to access link_enc before it's assigned in the USB4 case in the following assignment: config.dio_output_idx = link_enc->transmitter - TRANSMITTER_UNIPHY_A; [How] That assignment occurs later depending on the ASIC version. It's only needed on DCN31 and only after link_enc is already assigned. Fixes: 98643044 ("drm/amd/display: fix a crash on USB4 over C20 PHY") Reviewed-by:

For Aldebaran chip passthrough case we need to intimate SMU about special handling for SBR.On older chips we send LightSBR to SMU, enabling the same for Aldebaran. Slight difference, compared to previous chips, is on Aldebaran, SMU would do a heavy reset on SBR. Hence, the word Heavy instead of Light SBR is used for SMU to differentiate.

When an application having open file access to a node forks, its shared mappings also get reflected in the address space of child process even though it cannot access them with the object permissions applied. With the existing permission checks on the gem objects, it might be reasonable to also create the VMAs with VM_DONTCOPY flag so a user space application doesn't need to explicitly call the madvise(addr, len, MADV_DONTFORK) system call to prevent the pages in the mapped range to appear in the address space of the child process. It also prevents the memory leaks due to additional reference counts on the mapped BOs in the child process that prevented freeing the memory in the parent for which we had worked around earlier in the user space inside the thunk library. Additionally, we faced this issue when using CRIU to checkpoint restore an application that had such inherited mappings in the child which confuse CRIU when it mmaps on restore. Having this flag set for the render node VMAs helps. VMAs mapped via KFD already take care of this so this is needed only for the render nodes. To limit the impact of the change to user space consumers such as OpenGL etc, limit it to KFD BOs only. Acked-by:

We want to be able to call virt data exchange conditionally after gmc sw init to reserve bad pages as early as possible. Since this is a conditional call, we will need to call it again unconditionally later in the init sequence.

When doing suspend: There is no change to the power state flag of the vcn block, it is still POWER_STATE_ON. When doing resume: Need to open the power gate of the vcn block and set the power state flag of the VCN block to POWER_STATE_ON.
