Fix the increment to use sizeof(*topo). There is no issue currently, as sizeof(*topo) happens to be equal to sizeof(topo) on 64-bit systems (both evaluate to 8 bytes).

2026-01-29drm/xe/nvm: Fix double-free on aux add failureShuicheng Lin
After a successful auxiliary_device_init(), aux_dev->dev.release (xe_nvm_release_dev()) is responsible for the kfree(nvm). When there is failure with auxiliary_device_add(), driver will call auxiliary_device_uninit(), which call put_device(). So that the .release callback will be triggered to free the memory associated with the auxiliary_device. Move the kfree(nvm) into the auxiliary_device_init() failure path and remove the err goto path to fix below error.

2026-01-29drm/xe/nvm: Manage nvm aux cleanup with devresShuicheng Lin
Move nvm teardown to a devm-managed action registered from xe_nvm_init(). This ensures the auxiliary NVM device is deleted on probe failure and device detach without requiring explicit calls from remove paths. As part of this, drop xe_nvm_fini() from xe_device_remove() and from the survivability sysfs teardown, and remove the public xe_nvm_fini() API from the header.

2026-01-22drm, drm/xe: Fix xe userptr in the absence of CONFIG_DEVICE_PRIVATEThomas Hellström
CONFIG_DEVICE_PRIVATE is not selected by default by some distros, for example Fedora, and that leads to a regression in the xe driver since userptr support gets compiled out. It turns out that DRM_GPUSVM, which is needed for xe userptr support compiles also without CONFIG_DEVICE_PRIVATE, but doesn't compile without CONFIG_ZONE_DEVICE. Exclude the drm_pagemap files from compilation with !CONFIG_ZONE_DEVICE, and remove the CONFIG_DEVICE_PRIVATE dependency from CONFIG_DRM_GPUSVM and the xe driver's selection of it, re-enabling xe userptr for those configs. v2: - Don't compile the drm_pagemap files unless CONFIG_ZONE_DEVICE is set. - Adjust the drm_pagemap.h header accordingly.

2026-01-21drm/xe: Update wedged.mode only after successful reset policy changeLukasz Laguna
Previously, the driver's internal wedged.mode state was updated without verifying whether the corresponding engine reset policy update in GuC succeeded. This could leave the driver reporting a wedged.mode state that doesn't match the actual reset behavior programmed in GuC. With this change, the reset policy is updated first, and the driver's wedged.mode state is modified only if the policy update succeeds on all available GTs. This patch also introduces two functional improvements: - The policy is sent to GuC only when a change is required. An update is needed only when entering or leaving XE_WEDGED_MODE_UPON_ANY_HANG, because only in that case the reset policy changes. For example, switching between XE_WEDGED_MODE_UPON_CRITICAL_ERROR and XE_WEDGED_MODE_NEVER doesn't affect the reset policy, so there is no need to send the same value to GuC. - An inconsistent_reset flag is added to track cases where reset policy update succeeds only on a subset of GTs. If such inconsistency is detected, future wedged mode configuration will force a retry of the reset policy update to restore a consistent state across all GTs.

2026-01-21drm/xe/uapi: disallow bind queue sharingMatthew Auld
Currently this is very broken if someone attempts to create a bind queue and share it across multiple VMs. For example currently we assume it is safe to acquire the user VM lock to protect some of the bind queue state, but if allow sharing the bind queue with multiple VMs then this quickly breaks down. To fix this reject using a bind queue with any VM that is not the same VM that was originally passed when creating the bind queue. This a uAPI change, however this was more of an oversight on kernel side that we didn't reject this, and expectation is that userspace shouldn't be using bind queues in this way, so in theory this change should go unnoticed. Based on a patch from Matt Brost. v2 (Matt B): - Hold the vm lock over queue create, to ensure it can't be closed as we attach the user_vm to the queue. - Make sure we actually check for NULL user_vm in destruction path. v3: - Fix error path handling.

2026-01-15drm/xe: Cleanup unused header includesMatt Roper
clangd reports many "unused header" warnings throughout the Xe driver. Start working to clean this up by removing unnecessary includes in our .c files and/or replacing them with explicit includes of other headers that were previously being included indirectly. By far the most common offender here was unnecessary inclusion of xe_gt.h. That likely originates from the early days of xe.ko when xe_mmio did not exist and all register accesses, including those unrelated to GTs, were done with GT functions. There's still a lot of additional #include cleanup that can be done in the headers themselves; that will come as a followup series. v2: - Squash the 79-patch series down to a single patch.

2026-01-13drm/xe: Replace use of system_wq with tlb_inval->timeout_wqMarco Crivellari
This patch continues the effort to refactor workqueue APIs, which has begun with the changes introducing new workqueues and a new alloc_workqueue flag: commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq") commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag") The point of the refactoring is to eventually alter the default behavior of workqueues to become unbound by default so that their workload placement is optimized by the scheduler. Before that to happen, workqueue users must be converted to the better named new workqueues with no intended behaviour changes: system_wq -> system_percpu_wq system_unbound_wq -> system_dfl_wq This way the old obsolete workqueues (system_wq, system_unbound_wq) can be removed in the future. After a carefully evaluation, because this is the fence signaling path, we changed the code in order to use one of the Xe's workqueue. So, a new workqueue named 'timeout_wq' has been added to 'struct xe_tlb_inval' and has been initialized with 'gt->ordered_wq' changing the system_wq uses with tlb_inval->timeout_wq.

2026-01-12drm/xe/gsc: Make GSC FW load optional for newer platformsDaniele Ceraolo Spurio
On newer platforms GSC FW is only required for content protection features, so the core driver features work perfectly fine without it (and we did in fact not enable it to start with on PTL). Therefore, we can selectively enable the GSC only if the FW is found on disk, without failing if it is not found. Note that this means that the FW can now be enabled (i.e., we're looking for it) but not available (i.e., we haven't found it), so checks on FW support should use the latter state to decide whether to go on or not. As part of the rework, the message for FW not found has been cleaned up to be more readable. While at it, drop the comment about xe_uc_fw_init() since the code has been reworked and the statement no longer applies.
