As a backup to waiting on a user-interrupt from the GPU, we use a heavy and frequent timer to wake up the waiting process should we detect an inconsistency whilst waiting. After seeing a "missed interrupt", the next time we wait, we restart the heavy timer. This patch is more reluctant to restart the timer and will only do so if we have not see any interrupts since when we started the fake irq timer. If we are seeing interrupts, then the waiters are being woken normally and we had an incoherency that caused to miss last time - that is unlikely to reoccur and so taking the risk of stalling again seems pragmatic.

If the waiter was currently running, assume it hasn't had a chance to process the pending interrupt (e.g, low priority task on a loaded system) and wait until it sleeps before declaring a missed interrupt. References: https://bugs.freedesktop.org/show_bug.cgi?id=99816 Signed-off-by:

If an interrupt has been posted, and we were spinning on the active seqno waiting for it to advance but it did not, then we can expect that it will not see its advance in the immediate future and should call into the irq-seqno barrier. We can stop spinning at this point, and leave the difficulty of handling the coherency to the caller. Signed-off-by:

When the timer expires for checking on interrupt processing, check to see if any interrupts arrived within the last time period. If real interrupts are still being delivered, we can be reassured that we haven't missed the final interrupt as the waiter will still be woken. Only once all activity ceases, do we have to worry about the waiter never being woken and so need to install a timer to kick the waiter for a slow arrival of a seqno. Signed-off-by:

In Geminilake, the degamma table is enabled or disabled by the pipe CSC enable bit, so its active even when running in the legacy gamma mode. So always set sane values for that table, since the default value is all zeroes. This fixes blank screens after a suspend/resume cycle while legacy gamma is in use. Signed-off-by:
