[PATCH v2 1/3] drm/i915/gt: Relocate compression repacking WA for JSL/EHL

CACHE_MODE_0 registers should be saved and restored as part of the context, not during engine reset. Move the related workaround (Disable Repacking for Compression) from rcs_engine_wa_init() to icl_ctx_workarounds_init() for Jasper Lake and Elkhart Lake platforms.

[PATCH] kcov, usb: Fix invalid context sleep in softirq path on PREEMPT_RT

This issue was introduced by commit f85d39dd7ed8 ("kcov, usb: disable interrupts in kcov_remote_start_usb_softirq"). However, this creates a conflict on PREEMPT_RT kernels. The local_irq_save() call establishes an atomic context where sleeping is forbidden. Inside this context, kcov_remote_start() is called, which on PREEMPT_RT uses sleeping locks (spinlock_t and local_lock_t are mapped to rt_mutex). This results in a sleeping function called from invalid context. On PREEMPT_RT, interrupt handlers are threaded, so the re-entrancy scenario is already safely handled by the existing local_lock_t and the global kcov_remote_lock within kcov_remote_start(). Therefore, the outer local_irq_save() is not necessary. This preserves the intended re-entrancy protection for non-RT kernels while resolving the locking violation on PREEMPT_RT kernels. After making this modification and testing it, syzkaller fuzzing the PREEMPT_RT kernel is now running without stopping on latest announced Real-time Linux.

[CI 5/5] drm/i915/icl+/tc: Convert AUX powered WARN to a debug message

The BIOS can leave the AUX power well enabled on an output, even if this isn't required (on platforms where the AUX power is only needed for an AUX access). This was observed at least on PTL. To avoid the WARN which would be triggered by this during the HW readout, convert the WARN to a debug message.
