1feb64c49d drm/i915: Clear DRIVER_ATOMIC on a per-device basis
Currently we're clearing DRIVER_ATOMIC in driver.driver_features
for older platforms. This will not work correctly should we ever
have a system with and old and new GPU in it. While that is not
possible currently let's make the code more correct and use
the per-device driver_features instead.

6dfc4a8f13 drm/i915: Verify power domains after enabling them
After
commit 2cd9a689e9 ("drm/i915: Refactor intel_display_set_init_power() logic")
it makes more sense to check the power domain/well refcounts after
enabling the power domains functionality. Before that it's guaranteed
that most power wells (in the INIT domain) will have a reference held,
so not an interesting state.

While at it also add the check after the init_hw/fini_hw, disable and
suspend/resume steps. Make the test optional on a Kconfig option since
it may add substantial overhead: on VLV/CHV the corresponding PUNIT reg
access for each power well may take up to 20ms.

v2:
- Add the state check to more spots. (Chris)

v3:
- During suspend check the state before deiniting display core.
  Afterwards DC states are disabled (and so the dc_off power well is
  enabled) even though we don't hold a reference on it.
- Do the test conditionally based on a new Kconfig option. (Chris)

2cd9a689e9 drm/i915: Refactor intel_display_set_init_power() logic
The device global init_power_on flag is somewhat arbitrary and makes
debugging power refcounting problems difficult. Instead arrange things
so that all display power domain get has a corresponding put call. After
this change we have the following sequences:

driver loading:
intel_power_domains_init_hw();
<other init steps>
intel_power_domains_enable();

driver unloading:
intel_power_domains_disable();
<other uninit steps>
intel_power_domains_fini_hw();

system suspend:
intel_power_domains_disable();
<other suspend steps>
intel_power_domains_suspend();

system resume:
intel_power_domains_resume();
<other resume steps>
intel_power_domains_enable();

at other times while the driver is loaded:
intel_display_power_get();
...
intel_display_power_put();

07d8057219 drm/i915: Introduce intel_runtime_pm_disable to pair intel_runtime_pm_enable
Currently, we cancel the extra wakeref we have for !runtime-pm devices
inside power_wells_fini_hw. However, this is not strictly paired with
the acquisition of that wakeref in runtime_pm_enable (as the fini_hw may
be called on errors paths before we even call runtime_pm_enable). Make
the symmetry more explicit and include a check that we do release all of
our rpm wakerefs.

v2: Fixup transfer of ownership back to core whilst keeping our wakeref
count balanced.

If we pardon a per-engine reset, we may leave the STOP_RING bit asserted
in RING_MI_MODE resulting in the engine hanging. Unconditionally clear
it on the per-engine exit path as we know that either we skipped the
reset and so need the cancellation, or the reset was successful and the
cancellation is a no-op, or there was an error and we will follow up
with a full-reset or wedging (both of which will stop the engines again
as required).

a6476ebd43 drm/i915: Stop dropping irq around resets
A long time ago, we were afraid of handling interrupts and signaling
waiters during a reset, worrying that the confusion in request handling
would interfere with our attempts to process the reset in an orderly
fashion. Since then, we have isolated our irq-driven request handling by
virtue of the engine->timeline.lock and control of kthreads where
required, eliminating the danger of concurrently processing interrupts.

08e3e21a24 drm/i915: kill resource streamer support
After disabling resource streamer on ICL (due to it actually not
existing there), I got feedback that there have been some experimental
patches for mesa to use RS years ago, but nothing ever landed or shipped
because there was no performance improvement.

This removes it from kernel keeping the uapi defines around for
compatibility.

v2: - re-add the inadvertent removal of CTX_CTRL_INHIBIT_SYN_CTX_SWITCH
    - don't bother trying to document removed params on uapi header:
      applications should know that from the query.
      (from Chris)

v3: - disable CTX_CTRL_RS_CTX_ENABLE istead of removing it
    - reword commit message after Daniele confirmed no performance
      regression on his machine
    - reword commit message to make clear RS is being removed due to
      never been used
v4: - move I915_EXEC_RESOURCE_STREAMER to __I915_EXEC_ILLEGAL_FLAGS so
      the check on ioctl() is made much earlier by
      i915_gem_check_execbuffer() (suggested by Tvrtko)

900ccf30f9 drm/i915: Only force GGTT coherency w/a on required chipsets
Not all chipsets have an internal buffer delaying the visibility of
writes via the GGTT being visible by other physical paths, but we use a
very heavy workaround for all. We only need to apply that workarounds to
the chipsets we know suffer from the delay and the resulting coherency
issue.

Similarly, the same inconsistent coherency fouls up our ABI promise that
a write into a mmap_gtt is immediately visible to others. Since the HW
has made that a lie, let userspace know when that contract is broken.
(Not that userspace would want to use mmap_gtt on those chipsets for
other performance reasons...)

05c72e77cc drm/i915: Nuke the LVDS lid notifier
We broke the LVDS notifier resume thing in (presumably) commit
e2c8b8701e ("drm/i915: Use atomic helpers for suspend, v2.") as
we no longer duplicate the current state in the LVDS notifier and
thus we never resume it properly either.

Instead of trying to fix it again let's just kill off the lid
notifier entirely. None of the machines tested thus far have
apparently needed it. Originally the lid notifier was added to
work around cases where the VBIOS was clobbering some of the
hardware state behind the driver's back, mostly on Thinkpads.
We now have a few report of Thinkpads working just fine without
the notifier. So maybe it was misdiagnosed originally, or
something else has changed (ACPI video stuff perhaps?).

If we do end up finding a machine where the VBIOS is still causing
problems I would suggest that we first try setting various bits in
the VBIOS scratch registers. There are several to choose from that
may instruct the VBIOS to steer clear.

With the notifier gone we'll also stop looking at the panel status
in ->detect().

v2: Nuke enum modeset_restore (Rodrigo)

159b69bc0d drm/i915: Remove pci private pointer after destroying the device private
On an aborted module load, we unwind and free our device private - but
we left a dangling pointer to our privates inside the pci_device. After
the attempted aborted unload, we may still get a call to i915_pci_remove()
when the module is removed, potentially chasing stale data.

4fdd5b4e9a drm/i915: Fix fallout of fake reset along resume
commit b2209e62a4 ("drm/i915/execlists: Reset the CSB head tracking on
reset/sanitization") and commit 1288786b18 ("drm/i915: Move GEM sanitize
from resume_early to resume") show the conflicting requirements on the
code. We must reset the GPU before trashing live state on a fast resume
(hibernation debug, or error paths), but we must only reset our state
tracking iff the GPU is reset (or power cycled). This is tricky if we
are disabling GPU reset to simulate broken hardware; we reset our state
tracking but the GPU is left intact and recovers from its stale state.

v2: Again without the assertion for forcewake, no longer required since
commit b3ee09a4de ("drm/i915/ringbuffer: Fix context restore upon reset")
as the contexts are reset from the CS ensuring everything is powered up.

Fixes: b2209e62a4 ("drm/i915/execlists: Reset the CSB head tracking on reset/sanitization")

This should be a no-op in terms of our control flow, we move the
sanitization (GPU reset) from the bottom of the early resume phase to
the top of the next. However, following hibernation debug, the power
code skips the early resume phase, but as we are about to completely
restore the GTT mappings, we first need to stop the GPU using them i.e.
perform a GPU reset (i915_gem_sanitize()).

ec92ad00a3 drm/i915: Only sanitize GEM from late suspend
During testing we encounter a conflict between SUSPEND_TEST_DEVICES and
disabling reset (gem_eio/suspend). This results in the device continuing
on without being reset, but since it has gone through HW sanitization to
account for the suspend/resume cycle, we have to assume the device has
been reset to its defaults. A simple way around this is to skip the
sanitize phase for SUSPEND_TEST_DEVICES by moving it to suspend-late.

73b66f8731 drm/i915: Prepare GEM for suspend earlier
In order to prepare the GPU for sleeping, we may want to submit commands
to it. This is a complicated process that may even require some swapping
in from shmemfs, if the GPU was in the wrong state. As such, we need to
do this preparation step synchronously before the rest of the system has
started to turn off (e.g. swapin fails if scsi is suspended).
Fortunately, we are provided with a such a hook, pm_ops.prepare().

v2: Compile cleanup
v3: Fewer asserts, fewer problems?

v4: Ville pointed out that in some circumstances (such as switching off
the overlay) the display code may issue a GPU request. This is
unexpected, and will result in us going to sleep with us believing the
GPU is still awake (though all user work has been saved). Add a comment
to remind our future selves of what trouble brews.

4e8507ba77 drm/i915: Don't request a bug report for unsafe module parameters
Unsafe module parameters are just that, unsafe. If the user is foolish
enough to try them and the kernel breaks, they get to keep both pieces.
Don't ask them to file a bug report if they broke it themselves.

e01569ab96 drm/i915: Silence debugging DRM_ERROR for failing to suspend vlv powerwells
If we try to suspend a wedged device following a GPU reset failure, we
will also fail to turn off the rc6 powerwells (on vlv), leading to a
*ERROR*. This is quite expected in this case, so the best we can do is
shake our heads and reduce the *ERROR* to a debug so CI stops
complaining.
