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:

Fixes boards reporting bogus amounts of vram. after add this patch,the maximum GPU VRAM size is 64GB, otherwise only 64GB vram size will be used.

[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:

CP supports unmap queue with reset mode which only destroys specific queue without affecting others. Replacing whole gpu reset with reset queue mode for RAS poison consumption saves much time, and we can also fallback to gpu reset solution if reset queue fails. v2: Return directly if process is NULL; Reset queue solution is not applicable to SDMA, fallback to legacy way; Call kfd_unref_process after lookup process.

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. Refactor the data exchange function so it can be called multiple times without re-initializing the work item. v2: Cleaned up the code. Kept the original call to init_exchange_data() inside early init to initialize the work item, afterwards call exchange_data() when needed. Signed-off-by:

PM: dpm_run_callback(): pci_pm_resume+0x0/0x90 returns -110 [why] When playing the video: The power state flag of the vcn block is set to POWER_STATE_ON. 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. But at this time, the power state flag of the vcn block is already POWER_STATE_ON. The power status flag check in the "8f2cdef drm/amd/pm: avoid duplicate powergate/ungate setting" patch will return the amdgpu_dpm_set_powergating_by_smu function directly. As a result, the gate of the power was not opened, causing the subsequent ring test to fail. [how] In the suspend function of the vcn block, explicitly change the power state flag of the vcn block to POWER_STATE_OFF. BugLink: https://gitlab.freedesktop.org/drm/amd/-/issues/1828Signed-off-by:
