Previously we masked PCIe Link Control 2 register values with "7 << 9",
which was apparently intended to be the Transmit Margin field, but instead
was the high order bit of Transmit Margin, the Enter Modified Compliance
bit, and the Compliance SOS bit.
Correct the mask to "7 << 7", which is the Transmit Margin field.

Commit 8c0d3a02c130 ("PCI: Add accessors for PCI Express Capability")
added accessors for the PCI Express Capability so that drivers didn't
need to be aware of differences between v1 and v2 of the PCI
Express Capability.
Replace pci_read_config_word() and pci_write_config_word() calls with
pcie_capability_read_word() and pcie_capability_write_word().

Assume that intel_wakeref_get() may take the mutex, and perform other
sleeping actions in the course of its callbacks and so use might_sleep()
to ensure that all callers abide. Anything that cannot sleep has to use
e.g. intel_wakeref_get_if_active() to guarantee its avoidance of the
non-atomic paths.

Since the request is already on the HW as we perform its validation, it
and even its subsequent barrier may be concurrently retired before we
process the assertions. If it is retired already and so off the HW, our
assertions become void and we need to ignore them.

Since retirement may be running in a worker on another CPU, it may be
skipped in the local intel_gt_wait_for_idle(). To ensure the state is
consistent for our sanity checks upon load, serialise with the remote
retirer by waiting on the timeline->mutex.
Outside of this use case, e.g. on suspend or module unload, we expect the
slack to be picked up by intel_gt_pm_wait_for_idle() and so prefer to
put the special case serialisation with retirement in its single user,
for now at least.

For locking semantics it really doesn't matter when we grab the
ticket. But for lockdep validation it does: the acquire ctx is a fake
lockdep. Since other drivers might want to do a full multi-lock dance
in their fault-handler, not just lock a single dma_resv. Therefore we
must init the acquire_ctx only after we've done all the copy_*_user or
anything else that might trigger a pagefault. For msm this means we
need to move it past submit_lookup_objects.
Aside: Why is msm still using struct_mutex, it seems to be using
dma_resv_lock for general buffer state protection?
v2:
- Add comment to explain why the ww ticket setup is separate (Rob)
- Fix up error handling, we need to make sure we don't call
ww_acquire_fini without _init.

It's kinda really hard to get this wrong on a driver with both display
and dma_resv locking. But who ever knows, so better to make sure that
really all drivers nest these the same way.
For actual lock semantics the acquire context nesting doesn't matter.
But to teach lockdep what's going on with ww_mutex the acquire ctx is
a fake lockdep lock, hence from a lockdep pov it does matter. That's
why I figured better to include it.

fbdev uses the physical address of our framebuffer for its fb_mmap()
routine. While we need to adapt this address for the new io BAR, we have
to fix v5.4 first! The simplest fix is to restore the smem back to v5.3
and we will then probably have to implement our fbops->fb_mmap() callback
to handle local memory.

From inside an active timeline in the execbuf ioctl, we may try to
reclaim some space in the GGTT. We need GGTT space for all objects on
!full-ppgtt platforms, and for context images everywhere. However, to
free up space in the GGTT we may need to remove some pinned objects
(e.g. context images) that require flushing the idle barriers to remove.
For this we use the big hammer of intel_gt_wait_for_idle()
However, commit 7936a22dd466 ("drm/i915/gt: Wait for new requests in
intel_gt_retire_requests()") will continue spinning on the wait if a
timeline is active but lacks requests, as is the case during execbuf
reservation. Spinning forever is quite time consuming, so revert that
commit and start again.
In practice, the effect commit 7936a22dd466 was trying to achieve is
accomplished by commit 1683d24c1470 ("drm/i915/gt: Move new timelines
to the end of active_list"), so there is no immediate rush to replace
the looping.

Reset "panel" to NULL to avoid this problem.
Also change the format string of the error to %ld to print

In commit a79ca656b648 ("drm/i915: Push the wakeref->count deferral to
the backend"), I erroneously concluded that we last modify the engine
inside __i915_request_commit() meaning that we could enable concurrent
submission for userspace as we enqueued this request. However, this
falls into a trap with other users of the engine->kernel_context waking
up and submitting their request before the idle-switch is queued, with
the result that the kernel_context is executed out-of-sequence most
likely upsetting the GPU and certainly ourselves when we try to retire
the out-of-sequence requests.
As such we need to hold onto the effective engine->kernel_context mutex
lock (via the engine pm mutex proxy) until we have finish queuing the
request to the engine.

The general concept was that intel_timeline.active_count was locked by
the intel_timeline.mutex. The exception was for power management, where
the engine->kernel_context->timeline could be manipulated under the
global wakeref.mutex.
This was quite solid, as we always manipulated the timeline only while
we held an engine wakeref.
And then we started retiring requests outside of struct_mutex, only
using the timelines.active_list and the timeline->mutex. There we
started manipulating intel_timeline.active_count outside of an engine
wakeref, and so introduced a race between __engine_park() and
intel_gt_retire_requests(), a race that could result in the
engine->kernel_context not being added to the active timelines and so
losing requests, which caused us to keep the system permanently powered
up [and unloadable].
The race would be easy to close if we could take the engine wakeref for
the timeline before we retire -- except timelines are not bound to any
engine and so we would need to keep all active engines awake. The
alternative is to guard intel_timeline_enter/intel_timeline_exit for use
outside of the timeline->mutex.

Previously, we assumed we could use mutex_trylock() within an atomic
context, falling back to a worker if contended. However, such trickery
is illegal inside interrupt context, and so we need to always use a
worker under such circumstances. As we normally are in process context,
we can typically use a plain mutex, and only defer to a work when we
know we are being called from an interrupt path.

Just pass the atomic state+crtc to the .crtc_enable()
.crtc_disable(). Life is easier when you don't have to think
whether to pass the old or the new crtc state.

Rename pipe_config to new_crtc_state in the .crtc_enable() hooks.
The 'pipe_config' name is a zombie that we need to finally put down.

Get rid of the horrible aliasing drm_crtc and intel_crtc variables
in the crtc enable/disable hooks.

Just pass the atomic_state+crtc to the watermarks hooks. Eeasier
time for the caller when it doesn't have to think what to pass.

intel_modeset_setup_hw_state() doesn't need the crtc_state at the
top level scope. Move it to where it's needed.

Move the assert_vblank_disabled() into intel_crtc_vblank_on()
so that we don't have to inline it all over.
This does mean we now assert_vblank_disabled() during readout as well
but that is totally fine as it happens after drm_crtc_vblank_reset().
One can even argue it's what we want to do anyway to make sure
the reset actually happened.

We already have intel_crtc_vblank_on(). Add a counterpart so we
don't have to inline the disable+assert all over.

Just pass the atomic state and the crtc to intel_encoders_enable() & co.
Make life simpler when you don't have to think which state (old vs. new)
you have to pass in. Also constify the states while at it.
