While applying post-migration fixups to VF, GuC will not respond to any commands. This means submissions have no way of finishing. To avoid acquiring additional resources and then stalling on hardware access, pause the submission work. This will decrease the chance of depleting resources, and speed up the recovery. v2: Commented xe_irq_resume() call v3: Typo fix Signed-off-by: Tomasz Lis <tomasz.lis@intel.com> Cc: Michal Wajdeczko <michal.wajdeczko@intel.com> Cc: Michal Winiarski <michal.winiarski@intel.com> Reviewed-by: Michał Winiarski <michal.winiarski@intel.com> Link: https://lore.kernel.org/r/20250802031045.1127138-3-tomasz.lis@intel.com Signed-off-by: Michał Winiarski <michal.winiarski@intel.com>
