2ec4cf4057 drm/i915: Skip fence alignemnt check for the CCS plane
The CCS won't have the same stride as the main surface anyway so trying
to guard against the fence stride not matching the CCS stride is
not sensible. Just skip the fence vs. fb alignment check for the aux
plane.

b69a784f5e drm/i915: Always wake the device to flush the GTT
Since we hold the device wakeref when writing through the GTT (otherwise
the writes would fail), we presumed that before the device sleeps those
writes would naturally be flushed and that we wouldn't need our mmio
read trick. However, that presumption seems false and a sleepy bxt seems
to require us to always manually flush the GTT writes prior to direct
access.

cad9946c2a drm/i915: Always sanity check engine state upon idling
When we do a locked idle we know that afterwards all requests have been
completed and the engines have been cleared of tasks. For whatever
reason, this doesn't always happen and we may go into a suspend with
ELSP still full, and this causes an issue upon resume as we get very,
very confused.

If the engines refuse to idle, mark the device as wedged. In the process
we get rid of the maybe unused open-coded version of wait_for_engines
reported by Nick Desaulniers and Matthias Kaehlcke.

v2: Suppress the -EIO before suspend, but keep it for seqno wrap.

a575c67617 drm/i915: Recreate vmapping even when the object is pinned
Sometimes we know we are the only user of the bo, but since we take a
protective pin_pages early on, an attempt to change the vmap on the
object is denied because it is busy. i915_gem_object_pin_map() cannot
tell from our single pin_count if the operation is safe. Instead we must
pass that information down from the caller in the manner of
I915_MAP_OVERRIDE.

This issue has existed from the introduction of the mapping, but was
never noticed as the only place where this conflict might happen is for
cached kernel buffers (such as allocated by i915_gem_batch_pool_get()).
Until recently there was only a single user (the cmdparser) so no
conflicts ever occurred. However, we now use it to allocate batches for
different operations (using MAP_WC on !llc for writes) in addition to the
existing shadow batch (using MAP_WB for reads).

We could either keep both mappings cached, or use a different write
mechanism if we detect a MAP_WB already exists (i.e. clflush
afterwards), but as we haven't seen this issue in the wild (it requires
hitting the GPU reloc path in addition to the cmdparser) for simplicity
just allow the mappings to be recreated.

v2: Include the i915_MAP_OVERRIDE bit in the enum so the compiler knows
about all the valid values.

ffa9443fb3 drm/syncobj: Add a signal ioctl (v3)
This IOCTL provides a mechanism for userspace to trigger a sync object
directly.  There are other ways that userspace can trigger a syncobj
such as submitting a dummy batch somewhere or hanging on to a triggered
sync_file and doing an import.  This just provides an easy way to
manually trigger the sync object without weird hacks.

The motivation for this IOCTL is Vulkan fences.  Vulkan lets you create
a fence already in the signaled state so that you can wait on it
immediatly without stalling.  We could also handle this with a new
create flag to ask the driver to create a syncobj that is already
signaled but the IOCTL seemed a bit cleaner and more generic.

v2:
 - Take an array of sync objects (Dave Airlie)
v3:
 - Throw -EINVAL if pad != 0

e7aca5031a drm/syncobj: Allow wait for submit and signal behavior (v5)
Vulkan VkFence semantics require that the application be able to perform
a CPU wait on work which may not yet have been submitted.  This is
perfectly safe because the CPU wait has a timeout which will get
triggered eventually if no work is ever submitted.  This behavior is
advantageous for multi-threaded workloads because, so long as all of the
threads agree on what fences to use up-front, you don't have the extra
cross-thread synchronization cost of thread A telling thread B that it
has submitted its dependent work and thread B is now free to wait.

Within a single process, this can be implemented in the userspace driver
by doing exactly the same kind of tracking the app would have to do
using posix condition variables or similar.  However, in order for this
to work cross-process (as is required by VK_KHR_external_fence), we need
to handle this in the kernel.

This commit adds a WAIT_FOR_SUBMIT flag to DRM_IOCTL_SYNCOBJ_WAIT which
instructs the IOCTL to wait for the syncobj to have a non-null fence and
then wait on the fence.  Combined with DRM_IOCTL_SYNCOBJ_RESET, you can
easily get the Vulkan behavior.

v2:
 - Fix a bug in the invalid syncobj error path
 - Unify the wait-all and wait-any cases
v3:
 - Unify the timeout == 0 case a bit with the timeout > 0 case
 - Use wait_event_interruptible_timeout
v4:
 - Use proxy fence
v5:
 - Revert to a combination of v2 and v3
 - Don't use proxy fences
 - Don't use wait_event_interruptible_timeout because it just adds an
   extra layer of callbacks

9c19fb10a5 drm/syncobj: Add a callback mechanism for replace_fence (v3)
It is useful in certain circumstances to know when the fence is replaced
in a syncobj.  Specifically, it may be useful to know when the fence
goes from NULL to something valid.  This does make syncobj_replace_fence

case where there is no callback list, it spends a very short amount of

309a5482fa drm/syncobj: Add a race-free drm_syncobj_fence_get helper (v2)
The atomic exchange operation in drm_syncobj_replace_fence is sufficient
for the case where it races with itself.  However, if you have a race
between a replace_fence and dma_fence_get(syncobj->fence), you may end
up with the entire replace_fence happening between the point in time
where the one thread gets the syncobj->fence pointer and when it calls
dma_fence_get() on it.  If this happens, then the reference may be
dropped before we get a chance to get a new one.  The new helper uses
dma_fence_get_rcu_safe to get rid of the race.

This is also needed because it allows us to do a bit more than just get
a reference in drm_syncobj_fence_get should we wish to do so.

 - Call rcu_read_lock/unlock

71f23543d3 drm: kirin: Add mode_valid logic to avoid mode clocks we can't generate
Currently the hikey dsi logic cannot generate accurate byte
clocks values for all pixel clock values. Thus if a mode clock
is selected that cannot match the calculated byte clock, the
device will boot with a blank screen.

This patch uses the new mode_valid callback (many thanks to
Jose Abreu for upstreaming it!) to ensure we don't select
modes we cannot generate.

Also, since the ade crtc code will adjust the mode in mode_set,
this patch also adds a mode_fixup callback which we use to make
sure we are validating the mode clock that will eventually be
used.

1f1a36cc4d drm/vmwgfx: Fix incorrect command header offset at restart
Sometimes it appears like the device modifies the command header offset
member. So explicitly clear it when restarting after an error.

5f55be5f30 drm/vmwgfx: Support the NOP_ERROR command
Can be used by user-space applications to test and verify the kernel
command buffer error recovery functionality.

Malicious user-space apps could potentially use this command to slow down
graphics processing somewhat, but they could also accomplish the same thing
using a random malformed command so this should be considered safe.
At least as safe as it gets.

65b97a2bec drm/vmwgfx: Restart command buffers after errors
Previously we skipped the command buffer and added an extra fence to
avoid hangs due to skipped fence commands.
Now we instead restart the command buffer after the failing command,
if there are any commands left.
In addition we print out some information about the failing command
and its location in the command buffer.

Testing Done: ran glxgears using mesa modified to send the NOP_ERROR
command before each 10th clear and verified that we detected the device
error properly and that there were no other device errors caused by
incorrectly ordered command buffers. Also ran the piglit "quick" test
suite which generates a couple of device errors and verified that
they were handled as intended.

ef369904aa drm/vmwgfx: Move irq bottom half processing to threads
This gets rid of the irq bottom half tasklets and instead performs the
work needed in process context. We also convert irq-disabling spinlocks to
ordinary spinlocks.

This should decrease system latency for other system components, like
sound for example but has the potential to increase latency for processes
that wait on the GPU.

 - Store modified stride value in reg_params (Paulo)
