Avoid GT TLB invalidation timeouts by holding a PM ref when invalidations are inflight. v2: - Drop PM ref before signaling fence (CI) v3: - Move invalidation_fence_signal helper in tlb timeout to previous patch (Matthew Auld) Fixes:dd08ebf6c3("drm/xe: Introduce a new DRM driver for Intel GPUs") Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Nirmoy Das <nirmoy.das@intel.com> Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Nirmoy Das <nirmoy.das@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240719172905.1527927-4-matthew.brost@intel.com (cherry picked from commit0a382f9bc5) Requires: 46209ce5287b ("drm/xe: Add xe_gt_tlb_invalidation_fence_init helper") Requires: 0e414ab036e0 ("drm/xe: Drop xe_gt_tlb_invalidation_wait") Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
