Fix returned timeout in wait_seqno: remaining time, not time slept.
-
Fix return code of __wait_seqno.
-
MAX(ret, 0) is 0 if ret is negative, but if ret is negative we want
to return that negative value, meaning error.  Should've been
MIN(ret, 0), but I'll just rewrite it to clarify a wee bit.
-
If the GPU reset, call i915_gem_check_wedge and always return failure
like Linux does.  Caller must retry in that case.
-
Limit scope of ret and omit needless use of it to reduce confusion.
-
Make gmbus_wait_hw_status consistently use 50ms timeout like Linux.
-
Another attempt to fix the drm timed wait blarf blugh blahhh.
...aaaaand one more fix for __wait_seqno return value.
-
Also get the sense of the condition to wait until right.
