Dave Gordon ab0e455bd0 drm/i915: avoid wait_for_atomic() in non-atomic host2guc_action() ... Rather than using wait_for_atomic() when chacking for a response from the GuC, we can get the effect of a hybrid spin/sleep wait by breaking it into two stages. First, spin-wait for up to 10us to minimise latency for "quick" commands; then, if that times out, sleep-wait for up 10ms (the maximum allowed for a "slow" command). Being able to do this depends on the recent patch 18f4b84 drm/i915: Use atomic waits for short non-atomic ones and is similar to the hybrid approach in 1758b90 drm/i915: Use a hybrid scheme for fast register waits (although we can't use that as-is, because that interface doesn't quite match what we need here).
