We want to replace the inline wait_for() with an out-of-line hybrid busy/sleep wait_for() in the hopes of speeding up the communication wit the PCode unit. Indeed, on my i5-2500s, __gen6_update_ring_freq improves from 6,080,661ns to 8172ns. v2: Missed using _fw variants for sandybridge_pcode_read() Signed-off-by:

Ville Syrjälä reported that in the majority of wait_for(I915_READ()) he inspect, most completed within the first couple of reads and that the delay between those wait_for() reads was the ratelimiting step for many code paths. For example, __gen6_update_ring_freq() was blamed for slowing down boot by many milliseconds, but under Ville's scrutiny the issue was just excessive delay waiting for sandybridge_pcode_write(). We can eliminate the wait by initially using a busyspin upon the register read and only fallback to the sleeping loop in cases where the hardware is indeed too slow. A threshold of 2 microseconds is used as the initial ballpark. To avoid excessive code bloating from converting every wait_for() into a hybrid busy/sleep loop, we extend wait_for_register_fw() and export it for use by other callers. Signed-off-by:

This reverts commit ee042aa4. Something appears to be off in the timing, but as far as I can tell it is not along the event delivery path. The net effect appears to be rendering flicker (the current render buffer appears on the scanout, with what appears to be active rendering for a fraction of a frame) and is causing me a headache. The cursor is also being stalled by page flips, causing a "heavy mouse" and jitter. Daniel Stone did find what appears to the cause of the tearing, in https://lists.freedesktop.org/archives/intel-gfx/2016-June/099466.html That is the parameter passed to intel_atomic_commit_tail is the old_state but we need the new_state to wait upon. That leaves the question of how the CRC based tests didn't spot the error (how can we improve our tests?), the issue of legacy cursor stalling flips, and the issue of flips stalling the cursor. For the moment, step back until the condundrum of new/old state is reviewed along with more tests! Reported-and-tested-by:
