The WA buffer we use to capture context utilization contains GGTT references. This means its instructions have to be either fixed or re-emitted during VF post-migration recovery. This patch adds re-emitting content of the utilization WA BB during the recovery. The way we write to vram requires scratch buffer to be used before the whole block is memcopied. We are re-using a scratch buffer introduced in earlier part of the recovery. This is not a performance optimization, but a necessity to avoid creating dependencies between locks. v2: Notable rebase after "Prepare WA BB setup for more users" patch v3: Added error propagation 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: Michal Winiarski <michal.winiarski@intel.com> Link: https://lore.kernel.org/r/20250802031045.1127138-8-tomasz.lis@intel.com Signed-off-by: Michał Winiarski <michal.winiarski@intel.com>
