2025-12-12drm/xe/lnl: Drop pre-production workaround supportMatt Roper
LNL has been out long enough that all of our internal usage of pre-production hardware has been phased out and we no longer need to maintain workarounds that were exclusive to pre-production parts. Production LNL hardware always has B0 or later steppings for both graphics and media IP. Eliminate all workarounds that were exclusive to A-step hardware and set the 'has_prod_wa_only' device flag for LNL to make sure we warn and taint if someone tries to load the driver on an old pre-production part.

2025-12-12drm/xe: Track pre-production workaround supportMatt Roper
When we're initially enabling driver support for a new platform/IP, we usually implement all workarounds documented in the WA database in the driver. Many of those workarounds are restricted to early steppings that only showed up in pre-production hardware (i.e., internal test chips that are not available to the general public). Since the workarounds for early, pre-production steppings tend to be some of the ugliest and most complicated workarounds, we generally want to eliminate them and simplify the code once the platform has launched and our internal usage of those pre-production parts have been phased out. Let's add a flag to the device info that tracks which platforms still have support for pre-production workarounds for so that we can print a warning and taint if someone tries to load the driver on a pre-production part for a platform without pre-production workarounds. This will help our internal users understand the likely problems they'll encounter if they try to load the driver on an old pre-production device. The Xe behavior here is similar to what we've done for many years on i915 (see intel_detect_preproduction_hw()), except that instead of manually coding up ranges of device steppings that we believe to be pre-production hardware, Xe will use the hardware's own production vs pre-production fusing status, which we can read from the FUSE2 register. This fuse didn't exist on older Intel hardware, but should be present on all platforms supported by the Xe driver. Going forward, let's set the expectation that we'll start looking into removing pre-production workarounds for a platform around the time that platforms of the next major IP stepping are having their force_probe requirement lifted. This timing is just a rough guideline; there may be cases where some instances of pre-production parts are still being actively used in CI farms, internal device pools, etc. and we'll need to wait a bit longer for those to be swapped out. v2: - Fix inverted forcewake check v3: - Invert flag and add it to the platforms on which we still have pre-prod workarounds. (Jani, Lucas) v4: - Avoid checking pre-production on VF since they don't have access to the FUSE2 register.

Initializing automatic __free variables to NULL without need (e.g. branches with different allocations), followed by actual allocation is in contrary to explicit coding rules guiding cleanup.h: "Given that the "__free(...) = NULL" pattern for variables defined at the top of the function poses this potential interdependency problem the recommendation is to always define and assign variables in one statement and not group variable definitions at the top of the function when __free() is used."

2025-12-12drm/xe: Restore engine registers before restarting schedulers after GT resetJan Maslak
During GT reset recovery in do_gt_restart(), xe_uc_start() was called before xe_reg_sr_apply_mmio() restored engine-specific registers. This created a race window where the scheduler could run jobs before hardware state was fully restored. This caused failures in eudebug tests (xe_exec_sip_eudebug@breakpoint- waitsip-*) where TD_CTL register (containing TD_CTL_GLOBAL_DEBUG_ENABLE) wasn't restored before jobs started executing. Breakpoints would fail to trigger SIP entry because the debug enable bit wasn't set yet. Fix by moving xe_uc_start() after all MMIO register restoration, including engine registers and CCS mode configuration, ensuring all hardware state is fully restored before any jobs can be scheduled.

2025-12-12accel/amdxdna: Fix race where send ring appears full due to delayed head updateLizhi Hou
The firmware sends a response and interrupts the driver before advancing the mailbox send ring head pointer. As a result, the driver may observe the response and attempt to send a new request before the firmware has updated the head pointer. In this window, the send ring still appears full, causing the driver to incorrectly fail the send operation. This race can be triggered more easily in a multithreaded environment, leading to unexpected and spurious "send ring full" failures. To address this, poll the send ring head pointer for up to 100us before returning a full-ring condition. This allows the firmware time to update the head pointer.

2025-12-12Input: lkkbd - disable pending work before freeing deviceMinseong Kim
lkkbd_interrupt() schedules lk->tq via schedule_work(), and the work handler lkkbd_reinit() dereferences the lkkbd structure and its serio/input_dev fields. lkkbd_disconnect() and error paths in lkkbd_connect() free the lkkbd structure without preventing the reinit work from being queued again until serio_close() returns. This can allow the work handler to run after the structure has been freed, leading to a potential use-after-free. Use disable_work_sync() instead of cancel_work_sync() to ensure the reinit work cannot be re-queued, and call it both in lkkbd_disconnect() and in lkkbd_connect() error paths after serio_open().
