Let's ensure that we cannot run indefinitely without the hangcheck worker being queued. We removed it from being kicked on every request because we were kicking it a few millions times in every hangcheck interval and only once is necessary! However, that leaves us with the issue of what if userspace never waits for a request, or runs out of resources, what if userspace just issues a request then spins on BUSY_IOCTL?

Never go to sleep waiting on the GPU without first ensuring that we will get woken up. We have a choice of queuing the hangcheck before every schedule() or the first time we wakeup. In order to simply accommodate both the signaler and the ordinary waiter, move the queuing to the common point of enabling the irq. We lose the paranoid safety of ensuring that the hangcheck is active before the sleep, but avoid code duplication (and redundant hangcheck queuing).

One of the numerous VT-d workarounds we require is that the display hardware reads past the end of the buffer triggering VT-d faults. This is acknowledged in the code as being safe "since we fill the unused portions of the GGTT with the scratch page". Alas, that is no longer always true and so we trigger DMAR read faults. Skylake also requires another workaround to avoid mixing VT-d and unpopulated PTE, and so there we also need to ensure we fill unused entries with the scratch page. Reported-by:

So let's consider this as a continuation of SunrisePoint, i.e., SPT+. Since it is easy to get confused by a letter change: KBL = Kabylake - CPU/GPU codename. KBP = Kabypoint - PCH codename.

Move the encoder cloning check to happen earlier in the modeset. The main benefit will be that the debug output from a failed modeset will be less confusing as output_types can not indicate an invalid configuration during the later computation stages. For instance, what happened to me was kms_setmode was attempting one of its invalid cloning checks during which it asked for DP+VGA cloning on HSW. In this case the DP .compute_config() was executed after the FDI .compute_config() leaving the DP link clock (1.62 in this case) in port_clock, and then later the FDI BW computation tried to use that as the FDI link clock (which should always be 2.7). 1.62 x 2 wasn't enough for the mode it was trying to use, and so it ended up rejecting the modeset, not because of an invalid cloning configuration, but because of supposedly running out of FDI bandwidth. Took me a while to figure out what had actually happened. Signed-off-by:

Dave Gordon authored
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 18f4b843 drm/i915: Use atomic waits for short non-atomic ones and is similar to the hybrid approach in 1758b90e 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).

After assigning ourselves as the new bottom-half, we must perform a cursory check to prevent a missed interrupt. Either we miss the interrupt whilst programming the hardware, or if there was a previous waiter (for a later seqno) they may be woken instead of us (due to the inherent race in the unlocked read of b->tasklet in the irq handler) and so we miss the wake up.

As we only ever keep the first error state around, we can avoid some work that can be quite intrusive if we don't record the error the second time around. This does move the race whereby the user could discard one error state as the second is being captured, but that race exists in the current code and we hope that recapturing error state is only done for debugging. Note that as we discard the error state for simulated errors, igt that exercise error capture continue to function. Signed-off-by:

Some IS_ and HAS_ macros can return any non-zero value for true. One potential problem with that is that someone could assign them to integers and be surprised with the result. Therefore it is probably safer to do the conversion to 0/1 in the macros themselves. Luckily this does not seem to have an effect on code size.

For simplicity in testing, only report known rings in the mask. This allows userspace to try and trigger a missed irq on every ring and do a comparison between i915_ring_test_irq and i915_ring_missed_irq to see if any rings failed. v2: Move the debug message to after the rings are selected (so that the message accurately reflects reality) Signed-off-by:
