Add xe_gt_recovery_pending helper. This helper serves as the singular point to determine whether a GT recovery is currently in progress. Expected callers include the GuC CT layer and the GuC submission layer. Atomically visable as soon as vCPU are unhalted until VF recovery completes. v3: - Add GT layer xe_gt_recovery_inprogress (Michal) - Don't blow up in memirq not enabled (CI) - Add __memirq_received with clear argument (Michal) - xe_memirq_sw_int_0_irq_pending rename (Michal) - Use offset in xe_memirq_sw_int_0_irq_pending (Michal) v4: - Refactor xe_gt_recovery_inprogress logic around memirq (Michal) v5: - s/inprogress/pending (Michal) v7: - Fix typos, adjust comment (Michal) Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Michal Wajdeczko <michal.wajdeczko@intel.com> Reviewed-by: Tomasz Lis <tomasz.lis@intel.com> Link: https://lore.kernel.org/r/20251008214532.3442967-9-matthew.brost@intel.com
