irq_domain_add_linear() is going away as being obsolete now. Switch to the preferred irq_domain_create_linear(). That differs in the first parameter: It takes more generic struct fwnode_handle instead of struct device_node. Therefore, of_fwnode_handle() is added around the parameter. Note some of the users can likely use dev->fwnode directly instead of indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not guaranteed to be set for all, so this has to be investigated on case to case basis (by people who can actually test with the HW).

2026-07-15drm/xe/xe_ras: Add support for uncorrectable core-compute errorsRiana Tauro
Add structures and command for get soc error and process uncorrectable core-compute errors. Uncorrectable core-compute errors are classified into global and local errors. Global error is an error that affects the entire device requiring a reset. This type of error is not isolated. When an AER is reported and error_detected is invoked request an SBR (Secondary Bus Reset) from PCI core. Local error is confined to a specific component or context like a engine. These errors can be contained and recovered by resetting only the affected engine without disrupting the rest of the device. Upon detection of an uncorrectable local core-compute error, an AER is generated and GuC is notified of the error to trigger engine reset. Return recovered from PCI error callbacks for these errors as no action is needed.

2026-07-14drm/amdgpu/ras: only check bad page for address-based UMC injectionStanley.Yang
UMC error injection on MI300 series is dispatched by the RAS TA using the injection method; only the "coherent" methods are address based, the single-shot/persistent/ac-parity ones ignore the address. The debugfs control path validated the injection address against the bad page list for every UMC injection. On uniras (SMU v13+) devices the address is now validated by the ras_mgr inject handler, so the legacy debugfs bad page check only runs on the legacy RAS path; other ASICs keep injecting by address. In the ras_mgr handler an injection is treated as non address-based only when userspace passes the U64_MAX sentinel address and the method is a non-address method. In that case the address is cleared to 0 and the bad page / range validation is skipped; otherwise the injection address is validated as before.

2026-07-14drm/amd/display: Re-evaluate cursor mode on plane position/size changeJames Lin
[Why] dm_crtc_get_cursor_mode() only re-evaluates the required cursor mode (native vs overlay) when a top plane changes its scale, pixel format, enable state, or zpos/color pipeline. It does not re-evaluate when a plane changes only its destination rectangle (crtc_x, crtc_y, crtc_w, crtc_h) at a constant scale. A pure move/resize can create or remove a hole under the cursor, which changes whether the native cursor is valid. When a primary plane shrinks and no longer covers the cursor region, the cursor mode stays NATIVE and the cursor is not rendered over the uncovered area, so it becomes invisible there. This is caught by igt@amdgpu/amd_cursor_overlay@non-full, where the test CRC was a constant black value across all cursor positions instead of tracking the reference. [How] In the per-plane loop of dm_crtc_get_cursor_mode(), set consider_mode_change when any of crtc_x, crtc_y, crtc_w or crtc_h differs between the old and new plane state, so a plane move/resize forces re-evaluation of the cursor mode. The driver then correctly promotes the cursor to OVERLAY mode when the primary stops covering the cursor region.
