2026-01-08drm/amd: Clean up kfd node on surprise disconnectMario Limonciello (AMD)
When an eGPU is unplugged the KFD topology should also be destroyed for that GPU. This never happens because the fini_sw callbacks never get to run. Run them manually before calling amdgpu_device_ip_fini_early() when a device has already been disconnected. This location is intentionally chosen to make sure that the kfd locking refcount doesn't get incremented unintentionally.

In SRIOV, guest drivers no longer setup/destory VMR starting from mp0 v11_0_7. In bare-metal, if boot-time TMR is enabled, some generation (e.g., mp0 v13_0_x) don’t need runtime TMR allocation but still require SETUP_TMR command with tmr address 0 for backward compatibility. some newer generations require neither SETUP_TMR nor DESTROY_TMR and will return errors if they are sent. Driver relies on boot_time_tmr and autoload_supported to handle these cases correctly.

2026-01-07drm/amd/pm: Disable MMIO access during SMU Mode 1 resetPerry Yuan
During Mode 1 reset, the ASIC undergoes a reset cycle and becomes temporarily inaccessible via PCIe. Any attempt to access MMIO registers during this window (e.g., from interrupt handlers or other driver threads) can result in uncompleted PCIe transactions, leading to NMI panics or system hangs. To prevent this, set the `no_hw_access` flag to true immediately after triggering the reset. This signals other driver components to skip register accesses while the device is offline. A memory barrier `smp_mb()` is added to ensure the flag update is globally visible to all cores before the driver enters the sleep/wait state.
