drm/i915: prefer resource_size_t for everything stolen

Keeps things consistent now that we make use of struct resource. This

drm/i915: Only report a wakeup if the waiter was truly asleep

If we attempt to wake up a waiter, who is currently checking the seqno
it will be in the TASK_INTERRUPTIBLE state and ttwu will report success.
However, it is actually awake and functioning -- so delay reporting the
actual wake up until it sleeps. This fixes some spurious claims of
missed_breadcrumbs when running under heavy load; i.e. sufficient load to
preempt away the newly woken waiter before they complete their checks.
However, it does so at the cost of a rare false negative; where the
waiter changes between the check and ttwu -- the only way to fix that
would be to extend the reporting from ttwu where the check could be done
atomically.

v2: Defend against !CONFIG_SMP
v3: Don't filter out calls to wake_up_process
v4: Drop risky microoptimisation to skip wakeups

drm/i915: Stop listening to request resubmission from the signaler kthread

The intent here was that we would be listening to
i915_gem_request_unsubmit in order to cancel the signaler quickly and
release the reference on the request. Cancelling the signaler is done
directly via intel_engine_cancel_signaling (called from unsubmit), but
that does not directly wake up the signaling thread, and neither does
setting the request->global_seqno back to zero wake up listeners to the
request->execute waitqueue. So the only time that listening to the
request->execute waitqueue would wake up the signaling kthread would be
on the request resubmission, during which time we would already receive
wake ups from rejoining the global breadcrumbs wait rbtree.

Trying to wake up to release the request remains an issue. If the
signaling was cancelled and no other request required signaling, then it
is possible for us to shutdown with the reference on the request still
held. To ensure that we do not try to shutdown, leaking that request, we
kick the signaling threads whenever we disarm the breadcrumbs, i.e. on
parking the engine when idle.

v2: We do need to be sure to release the last reference on stopping the
kthread; asserting that it has been dropped already is insufficient.

agp/intel: Flush all chipset writes after updating the GGTT

Before accessing the GGTT we must flush the PTE writes and make them
visible to the chipset, or else the indirect access may end up in the
wrong page. In commit 3497971a71d8 ("agp/intel: Flush chipset writes

pwrite and for capturing GPU error states, but it was presumed that the
explicit calls to intel_gtt_chipset_flush() were sufficient for the
execbuffer path. However, we have not been flushing the chipset between
the PTE writes and access via the GTT itself.

For simplicity, do the flush after any PTE update rather than try and
batch the flushes on a just-in-time basis.

drm/i915: Restore GT performance in headless mode with DMC loaded

It seems that the DMC likes to transition between the DC states a lot when
there are no connected displays (no active power domains) during command
submission.

This activity on DC states has a negative impact on the performance of the
chip with huge latencies observed in the interrupt handlers and elsewhere.
Simple tests like igt/gem_latency -n 0 are slowed down by a factor of
eight.

Work around it by introducing a new power domain named,
POWER_DOMAIN_GT_IRQ, associtated with the "DC off" power well, which is
held for the duration of command submission activity.

CNL has the same problem which will be addressed as a follow-up. Doing
that requires a fix for a DC6 context corruption problem in the CNL DMC
firmware which is yet to be released.

drm/i915/execlists: Cache ELSP register offset

Currently on every submission, we recalculate the ELSP register offset
for the engine, after chasing the pointers to find the iomem base. Since
this is fixed for the lifetime of the driver, record the offset in the
execlists struct.

In practice the difference is negligible, it just happens to remove 27
bytes of eyesore pointer dancing from next to the hottest instruction
(which is itself due to stalling for a cache miss) in perf profiles of
the execlists_submission_tasklet().

v2: Trim off one more elsp local.

drm/i915: Refactor common list iteration over GGTT vma

In quite a few places, we have a list iteration over the vma on an
object that only want to inspect GGTT vma. By construction, these are
placed at the start of the list, so we have copied that knowledge into
many callsites. Pull that knowledge back to i915_vma.h and provide a
for_each_ggtt_vma() to tidy up the code.

v2: Add a backreference from vma_create() to remind ourselves why we put

drm/i915: Track GGTT writes on the vma

As writes through the GTT and GGTT PTE updates do not share the same
path, they are not strictly ordered and so we must explicitly flush the
indirect writes prior to modifying the PTE. We do track outstanding GGTT
writes on the object itself, but since the object may have multiple GGTT
vma, that is overly coarse as we can track and flush individual vma as
required.

Whilst here, update the GGTT flushing behaviour for Cannonlake.

v2: Hard-code ring offset to allow use during unload (after RCS may have
been freed, or never existed!)

drm/i915: Remove vma from object on destroy, not close

Originally we translated from the object to the vma by walking
obj->vma_list to find the matching vm (for user lookups). Now we process
user lookups using the rbtree, and we only use obj->vma_list itself for
maintaining state (e.g. ensuring that all vma are flushed or rebound).
As such maintenance needs to go on beyond the user's awareness of the
vma, defer removal of the vma from the obj->vma_list from i915_vma_close()
to i915_vma_destroy()
