2026-03-13drm/panel: novatek-nt36672a: Convert to mipi_dsi_*_multi() helpersChintan Patel1-64/+30
Convert the driver to use the non-deprecated mipi_dsi_*_multi() helpers and mipi_dsi_msleep(). Switch DCS command sequences to the multi context API and accumulate errors via struct mipi_dsi_multi_context. Replace open-coded error handling with the multi helpers and convert nt36672a_send_cmds() and power sequencing accordingly. This patch is intended to functionally be a no-op, though there is one slight change. Previously a failure in regulator_bulk_disable() would have caused nt36672a_panel_unprepare() to return an error. Now it won't. No other errors in nt36672a_panel_unprepare() were propagated, so this makes things consistent.

2026-03-13arm_mpam: Disable preemption when making accesses to fake MSC in kunit testBen Horgan1-5/+13
Accesses to MSC must be made from a cpu that is affine to that MSC and the driver checks this in __mpam_write_reg() using smp_processor_id(). A fake in-memory MSC is used for testing. When using that, it doesn't matter which cpu we access it from but calling smp_processor_id() from a preemptible context gives warnings when running with CONFIG_DEBUG_PREEMPT. Add a test helper that wraps mpam_reset_msc_bitmap() with preemption disabled to ensure all (fake) MSC accesses are made with preemption disabled.

2026-03-13arm_mpam: Fix null pointer dereference when restoring bandwidth countersBen Horgan1-0/+2
When an MSC supporting memory bandwidth monitoring is brought offline and then online, mpam_restore_mbwu_state() calls __ris_msmon_read() via ipi to restore the configuration of the bandwidth counters. It doesn't care about the value read, mbwu_arg.val, and doesn't set it leading to a null pointer dereference when __ris_msmon_read() adds to it. This results in a kernel oops with a call trace such as: Call trace: __ris_msmon_read+0x19c/0x64c (P) mpam_restore_mbwu_state+0xa0/0xe8 smp_call_on_cpu_callback+0x1c/0x38 process_one_work+0x154/0x4b4 worker_thread+0x188/0x310 kthread+0x11c/0x130 ret_from_fork+0x10/0x20 Provide a local variable for val to avoid __ris_msmon_read() dereferencing a null pointer when adding to val.

2026-03-13drm/i915/dp: Simplify forcing a link retrainingImre Deak1-2/+2
Since both the DP SST and MST HPD IRQ handlers call intel_dp_handle_link_service_irq() with LINK_STATUS_CHANGED set in irq_mask if intel_dp->link.force_retrain is set, checking for the former flag is sufficient to determine if the link status needs to be checked (which includes retraining the link if this is forced); remove checking for the latter flag. Since LINK_STATUS_CHANGED is currently set unconditionally for DP SST, extend the related comment to note that it must be set if intel_dp->link.force_retrain is set (in case setting LINK_STATUS_CHANGED becomes conditional on DPCD_REV).

2026-03-13PCI: Use pr_warn_once() for ACS parameter parse failureRichard Cheng1-1/+1
When the ACS command line parameter cannot be parsed, the kernel skips applying the requested ACS override. This indicates an invalid boot parameter and should not be logged at informational level. Use pr_warn_once() so the message is surfaced as a warning while still avoiding repeated log spam during device enumeration.

2026-03-12drm/xe/wa: Drop redundant entries for Wa_16021867713 & Wa_14019449301Matt Roper1-14/+0
The Xe2_HPM-specific RTP table entries for Wa_16021867713 and Wa_14019449301 were removed by commit 941f538b0af8 ("drm/xe: Consolidate workaround entries for Wa_16021867713") and commit aa0f0a678370 ("drm/xe: Consolidate workaround entries for Wa_14019449301") in favor of alternate entries earlier in the table that cover a wider range of IP versions. However these Xe2_HPM-specific entries were accidentally resurrected during a backmerge, which causes the Xe driver to complain on probe about two entries trying to program the same registers+bits: <3> [48.491155] xe 0000:03:00.0: [drm] *ERROR* Tile0: GT1: discarding save-restore reg 1c3f1c (clear: 00000008, set: 00000008, masked: no, mcr: no): ret=-22 <3> [48.491211] xe 0000:03:00.0: [drm] *ERROR* Tile0: GT1: discarding save-restore reg 1d3f1c (clear: 00000008, set: 00000008, masked: no, mcr: no): ret=-22 <3> [48.491225] xe 0000:03:00.0: [drm] *ERROR* Tile0: GT1: discarding save-restore reg 1c3f08 (clear: 00000020, set: 00000020, masked: no, mcr: no): ret=-22 <3> [48.491238] xe 0000:03:00.0: [drm] *ERROR* Tile0: GT1: discarding save-restore reg 1d3f08 (clear: 00000020, set: 00000020, masked: no, mcr: no): ret=-22 Re-drop the redundant Xe2_HPM-specific entries to eliminate the dmesg errors.

2026-03-12accel/amdxdna: Allow forcing IOVA-based DMA via module parameterLizhi Hou10-32/+325
The amdxdna driver normally performs DMA using userspace virtual address plus PASID. For debugging and validation purposes, add a module parameter, force_iova, to force DMA to go through IOMMU IOVA mapping. When force_iova=1 is set, the driver will allocate and map DMA buffers using IOVA.

2026-03-12Input: psmouse - remove dedicated kpsmoused workqueueDmitry Torokhov2-27/+7
The only user of psmouse_queue_work() and therefore kpsmoused workqueue is psmouse-base itself, when it tries to schedule the resync work. Since resyncing is not going to race with itself we no longer need the dedicated ordered workqueue. Remove it and switch to using regular (non-delayed) work structure scheduled on the default workqueue. Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

The original code uses flush_workqueue() in psmouse_disconnect() to ensure the completion of both resync_work and dev3_register_work. Given that alps_disconnect() already uses disable_delayed_work_sync() to cancel dev3_register_work, replacing flush_workqueue() with disable_delayed_work_sync(&psmouse->resync_work) is more robust and efficient.
