drm/i915: Remove intel_flip_work infrastructure
This gets rid of all the interactions between the legacy flip code and
the modeset code. Yay!
This highlights an ommission in the atomic paths, where we fail to
apply a boost to the pending rendering when we miss the target vblank.
But the existing code is still dead and can be removed.
v2: Note that the boosting doesn't work in atomic (Chris).

drm/i915: Unbreak gpu reset vs. modeset locking
Taking the modeset locks unconditionally isn't the greatest idea,
because atm that part is still broken and times out (and then atomic
keels over). And there's really no reason to do so, the old code
didn't do that either.
To make the patch a bit simpler let's also nuke 2 cases that are only
around for the old mmioflip paths. Atomic nonblocking workers will not
die (minus bugs) when a gpu reset happens.
And of course this doesn't fix any of the gpu reset vs. modeset
deadlock fun, but it at least stop modern CI machines from keeling
over all over the place for no reason at all.
And we still have the explicit testcases to run the fake gpu reset, so
coverage isn't that much worse.
v2: Split out additional changes on top, restrict this to purely reducing
the critical section of modeset locks.
v2: Review from Maarten
- update comments
- don't oops when state is NULL in intel_finish_reset, but try to at
least still drop locks properly. The hw is going to be toast anyway.

drm/atomic-helper: Fix leak in disable_all
The legacy plane->fb pointer is refcounted by calling
drm_atomic_clean_old_fb().
In practice this isn't a real problem because:
- The caller in the i915 gpu reset code restores the original state
again, which means the plane->fb pointer won't change, hence can't
leak.
- Drivers using drm_atomic_helper_shutdown call the fbdev cleanup
first, and that usually cleans up the fb through
drm_remove_framebuffer, which does this correctly.
- Without fbdev the only framebuffers are from userspace, and those
get cleaned up (again using drm_remove_framebuffer) befor the driver
can even be unloaded.
But in i915 I've switched the cleanup sequence around so that the
_shutdown() calls happens after the drm_remove_framebuffer(), which is
how I discovered this issue.
v2: My analysis why the current code was ok for gpu reset and
suspend/resume was correct, but then I totally failed to realize that
we better keep this symmetric. Thanksfully CI noticed that for
balance, a refcounting bug must exist at 2 places if previously there
was no issue ...
v3: Don't be lazy and compute the plane_mask in
commit_duplicated_state properly too, instead of just using ~0U.

drm/i915: Fix cursor updates on some platforms
Turns out that just writing CURPOS isn't sufficient to move the cursor
on some platforms. My 830 works just fine, but eg. 945 and PNV don't.
On those platforms we need to arm even the CURPOS update with a
CURBASE write.
Even worse, a write to any of the cursor register apart from CURBASE
will cancel an already pending cursor update. So if we have armed a
CURCNTR/CURBASE update, a subsequent CURPOS write prior to vblank
would cancel that armed update. Thus we're left with a cursor that
doesn't appear to move, or even change shape.
Fix the problem by always performing the CURBASE write after a
CURPOS write. Bspec is somewhat unclear which platforms actually
require this CURBASE write and which don't. So to keep it simple
and to make sure we really fix the problem across all supported
devices, let's just perform the CURBASE write unconditionally.

drm/i915/gen9+: Don't remove secondary power well requests
So far in an attempt to make sure all power wells get disabled during
display uninitialization the driver removed any secondary request bits
(BIOS, KVMR, DEBUG) that were set for a given power well. The known
source for these requests was DMC's request on power well 1 and the misc
IO power well. Since DMC is inactive (DC states are disabled) at the
point we disable these power wells, there shouldn't be any reason to
leave them on. However there are two problems with the above
assumption: Bspec requires that the misc IO power well stays enabled
(without providing a reason) and there can be KVMR requests that we
can't remove anyway (the KVMR request register is R/O). Atm, a KVMR
request can trigger a timeout WARN when trying to disable power wells.
To make the code aligned to Bspec and to get rid of the KVMR WARN, don't
try to remove the secondary requests, only detect them and stop polling
for the power well disabled state when any one is set.
Also add a comment about the timeout values required by Bspec when
enabling power wells and the fact that waiting for them to get disabled
is not required by Bspec.

drm/i915: Only free the oldest stale context before allocating
Currently, we move all unreferenced contexts to an RCU free list and
then onto a worker for eventual reaping. To compensate against this
growing into a long list with frequent allocations starving the system
of available memory, before we allocate a new context we reap all the
stale contexts. This puts all the cost of destroying the context into
the next allocator, which is presumably more sensitive to syscall
latency and unfair. We can limit the number of contexts being freed by
the new allocator to both keep the list trimmed and to allow the
allocator to be reasonably fast.

drm/i915/edp: Add a T12 panel delay quirk to fix DP AUX CH timeouts
This patch fixes the DP AUX CH timeouts observed during CI IGT
tests thus fixing the CI failures. This is done by adding a
quirk for a particular PCI device that requires the panel power
cycle delay (T12) to be set to 800ms which is 300msecs more than
the minimum value specified in the eDP spec. So a quirk is
implemented for that specific PCI device.
v4:
* Add Bugzilla links for FDO bugs in the commit message (Ville, Jani)
v3:
* Change some comments, specify the delay as 800 * 10 (Ville)
v2:
* Change the function and variable names to from PPS_T12_
to _T12 since it is a T12 delay (Clint)

drm/i915/fbdev: Check for existence of ifbdev->vma before operations
Commit
fabef825626d ("drm/i915: Drop struct_mutex around frontbuffer
flushes") adds a dependency to ifbdev->vma when flushing the framebufer,
but the checks are only against the existence of the ifbdev->fb and not
against ifbdev->vma. This leaves a window of opportunity where we may
try to operate on the fbdev prior to it being probed (thanks to
asynchronous booting).

drm/i915: Avoid undefined behaviour of "u32 >> 32"
When computing a hash for looking up relocation target handles in an
execbuf, we start with a large size for the hashtable and proceed to
halve it until the allocation succeeds. The final attempt is with an
order of 0 (i.e. a single element). This means that we then pass bits=0

element. Right shifting a value by the width of the operand is
undefined, so limit the smallest hash table we use to order 1.

drm/i915: Avoid keeping waitboost active for signaling threads
Once a client has requested a waitboost, we keep that waitboost active
until all clients are no longer waiting. This is because we don't
distinguish which waiter deserves the boost. However, with the advent of
fence signaling, the signaler threads appear as waiters to the RPS
interrupt handler. So instead of using a single boolean to track when to
keep the waitboost active, use a counter of all outstanding waitboosted
requests.
At this point, I have removed all vestiges of the rate limiting on
clients. Whilst this means that compositors should remain more fluid,
it also means that boosts are more prevalent. See commit
b29c19b64528
("drm/i915: Boost RPS frequency for CPU stalls") for a longer discussion
on the pros and cons of both approaches.
A drawback of this implementation is that it requires constant request
submission to keep the waitboost trimmed (as it is now cancelled when the
request is completed). This will be fine for a busy system, but near
idle the boosts may be kept for longer than desired (effectively tens of
vblanks worstcase) and there is a reliance on rc6 instead.

drm/i915: Drop flushing of the object free list/worker from i915_gem_suspend
i915_gem_suspend() is called from all of our finalization paths
(suspend, hibernate, unload). i915_gem_drain_freed_objects() adds an
arbitrary delay as it uses an rcu_barrier() to ensure that there are no
more freed objects in flight, and this delay causes a large amount of
variability in suspend timings. For S3 suspend, we do not need to free
pages as doing so does not impact at all upon the system in its
suspended state, unlike S4 hibernation where we do want the hibernation
image to be as small as possible. Therefore we can forgo waiting inside
i915_gem_suspend(), so long as we ensure that we do cleanup before
unload (see i915_gem_load_cleanup()) and prefer to reap our objects
prior to hibernation (see i915_gem_freeze()).
Removing the rcu_barrier() from i915_gem_suspend() improves S3 latency
by about 30ms on Skylake (ymmv).

drm/i915: Cancel pending execlists irq handler upon idling
Due to the slight asynchronicity in handling the execlists interrupts
(i.e. we defer the work to a handler that may consume more than one
interrupt event), when the engine is idle we may still have an irq
tasklet queued (especially when it has been deferred to a ksoftirqd).
At the beginning of the tasklet, we assert that we do hold a device
wakeref for the access we are about to perform. This assumes that when
we idle and release the GT wakeref, all execlists work has been
completed (since the elsp tracking says the hw is idle). However, there
may still be a tasklet queued, so as we mark the engine idle, also
cancel any pending tasklet.
