All contexts require an update of state data, as the data includes GGTT references to memirq-related buffers. Default contexts need these references updated as well, because they are not refreshed when a new context is created from them. The way we write to vram requires scratch buffer to be used before the whole block is memcopied. Since using kalloc() within specific recovery functions would lead to unintended relations between locks, we are allocating the buffer earlier, before any locks are taken. The same buffer will be used for other steps of the recovery. v2: Update addresses by xe_lrc_write_ctx_reg() rather than set_memory_based_intr() v3: Renamed parameter, reordered parameters in some functs v4: Check if have MEMIRQ, move `xe_gt*` funct to proper file v5: Revert back to requiring scratch buffer, but allocate it earlier this time Signed-off-by: Tomasz Lis <tomasz.lis@intel.com> Cc: Michal Wajdeczko <michal.wajdeczko@intel.com> Cc: Michal Winiarski <michal.winiarski@intel.com> Acked-by: Satyanarayana K V P <satyanarayana.k.v.p@intel.com> Reviewed-by: Michal Winiarski <michal.winiarski@intel.com> Link: https://lore.kernel.org/r/20250802031045.1127138-6-tomasz.lis@intel.com Signed-off-by: Michał Winiarski <michal.winiarski@intel.com>
