Mika Kuoppala 47e9766df0 drm/i915: Fix timeout with missed interrupts in __wait_seqno ... Commit 094f9a54e3 ("drm/i915: Fix __wait_seqno to use true infinite timeouts") added support for __wait_seqno to detect missing interrupts and go around them by polling. As there is also timeout detection in __wait_seqno, the polling and timeout detection were done with the same timer. When there has been missed interrupts and polling is needed, the timer is set to trigger in (now + 1) jiffies in future, instead of the caller specified timeout. Now when io_schedule() returns, we calculate the jiffies left to timeout using the timer expiration value. As the current jiffies is now bound to be always equal or greater than the expiration value, the timeout_jiffies will become zero or negative and we return -ETIME to caller even tho the timeout was never reached. Fix this by decoupling timeout calculation from timer expiration. v2: Commit message with some sense in it (Chris Wilson) v3: add parenthesis on timeout_expire calculation v4: don't read jiffies without timeout (Chris Wilson) Signed-off-by: Mika Kuoppala <mika.kuoppala@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>		2013-12-12 15:27:21 +01:00
