2026-01-08drm/gpuvm: drm_gpuvm_bo_obtain() requires lock and staged modeAlice Ryhl
In commit 9ce4aef9a5b1 ("drm/gpuvm: take GEM lock inside drm_gpuvm_bo_obtain_prealloc()") we update drm_gpuvm_bo_obtain_prealloc() to take locks internally, which means that it's only usable in immediate mode. In this commit, we notice that drm_gpuvm_bo_obtain() requires you to use staged mode. This means that we now have one variant of obtain for each mode you might use gpuvm in. To reflect this information, we add a warning about using it in immediate mode, and to make the distinction clearer we rename the method with a _locked() suffix so that it's clear that it requires the caller to take the locks.

2026-01-08drm/gpuvm: take GEM lock inside drm_gpuvm_bo_obtain_prealloc()Alice Ryhl
When calling drm_gpuvm_bo_obtain_prealloc() and using immediate mode, this may result in a call to ops->vm_bo_free(vm_bo) while holding the GEMs gpuva mutex. This is a problem if ops->vm_bo_free(vm_bo) performs any operations that are not safe in the fence signalling critical path, and it turns out that Panthor (the only current user of the method) calls drm_gem_shmem_unpin() which takes a resv lock internally. This constitutes both a violation of signalling safety and lock inversion. To fix this, we modify the method to internally take the GEMs gpuva mutex so that the mutex can be unlocked before freeing the preallocated vm_bo. Note that this modification introduces a requirement that the driver uses immediate mode to call drm_gpuvm_bo_obtain_prealloc() as it would otherwise take the wrong lock.

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.

2026-01-07gpu: nova-core: use CStr::from_bytes_until_nul() and remove util.rsJohn Hubbard
The util.rs module contained a single helper function, str_from_null_terminated(), which duplicated functionality that is now available in core::ffi::CStr. Specifically, CStr::from_bytes_until_nul() is available in the kernel's minimum supported Rust version (1.78.0), so it time to stop using this custom workaround.

2026-01-07drm/xe: Validate preferred system memory placement in xe_svm_range_validateMatthew Brost
Ensure preferred system memory placement is checked in xe_svm_range_validate when dpagemap is NULL. Without this check, a prefetch to system memory may become a no-op because device memory is considered a valid placement.
