We don't keep the workarounds for pre-production hardware
(see intel_detect_preproduction_hw) thus we can drop some
extra steps during firmware upload needed only for unsupported

The workaround for this is described as:
"if RenderSurfaceState.Num_Multisamples > 1, disable RCC clock gating if
RenderSurfaceState.Num_Multisamples == 1, set 0x7010[14] = 1"
Further documentation in the internal bug referenced by the bspec
suggest that any of the above suggestions should suffice to fix the
issue. We are going with disabling RCC clock gating.
Unfortunately, what we are doing doesn't match the name of the
workaround, but at least it matches its description.
This change improves CNL stability by avoiding some of the hangs seen in
the platform.

Apparently setting up a bunch of GT registers before we've properly
initialized the rest of the GT hardware leads to these setting being
lost. So looks like I broke HSW with commit b7048ea12f ("drm/i915:
Do .init_clock_gating() earlier to avoid it clobbering watermarks")
by doing init_clock_gating() too early. This should actually affect
other platforms as well, but apparently not to such a great degree.
What I was ultimately after in that commit was to move the
ilk_init_lp_watermarks() call earlier. So let's undo the damage and
move init_clock_gating() back to where it was, and call
ilk_init_lp_watermarks() just before the watermark state readout.
This highlights how fragile and messed up our init order really is.
I wonder why we even initialize the display before gem. The opposite
order would make much more sense to me...
v2: Keep WaRsPkgCStateDisplayPMReq:hsw early as it really must
be done before all planes might get disabled.

The shared fence array is not autopruning and may continue to grow as an
object is shared between new timelines. Take the opportunity when we
think the object is idle (we have to confirm that any external fence is
also signaled) to decouple all the fences.
We apply a similar trick after waiting on an object, see commit
e54ca97747 ("drm/i915: Remove completed fences after a wait")
v2: No longer need to handle the batch pool as a special case.
v3: Need to trylock from within i915_vma_retire as this may be called
form the shrinker - and we may later try to allocate underneath the
reservation lock, so a deadlock is possible.

The handling of contexts are peculiar. Instead of tieing their vma to
activity, we pin the context. This means that we cannot simply unbind
the context object itself at will (which would normally cause us to wait
for the vma to be idle), but must manually idle the GPU and retire
requests first.
A consequence of this peculiarity is when doing a last desperate attempt
to recover memory. If the memory is tied up inside active context
objects, we will fail to recover any memory simply by trying to unbind
the objects without first doing a wait-for-idle.
A side-effect of removing the call to shrinker_lock_uninterruptible()
from i915_gem_shrinker_oom() was that we removed an unlocked
wait-for-idle, and so lost the "natural" shrinkage of context objects.
By replacing that with a locked wait from inside i915_gem_shrink(), we
not only replace it with the ability to recover all context objects, but
do so for all i915_gem_shrink_all() callers.
v2: Switching requires request allocation, which is not permitted from
inside the shrinker as it only uses ordinary allocations.

Since commit 632c6e4ede ("drm/vblank: Fix flip event vblank count")
even drivers that don't implement accurate vblank timestamps will end
up using drm_crtc_accurate_vblank_count(). That leads to a WARN every

as every frame for each active crtc.
Considering drm_crtc_accurate_vblank_count() is never any worse than
the drm_vblank_count() we used previously, let's just skip the WARN
unless DRM_UT_VBL is enabled. That way people won't be bothered by
this unless they're debugging vblank code. And let's also change it

Accessing the THIS_MODULE directly is only possible when modules
are enabled, otherwise we get a build failure:
drivers/gpu/drm/amd/amdgpu/amdgpu_virt.c: In function 'amdgpu_virt_init_data_exchange':
drivers/gpu/drm/amd/amdgpu/amdgpu_virt.c:331:20: error: dereferencing pointer to incomplete type 'struct module'
Further, THIS_MODULE is NULL when the driver is built-in, so the
code would likely cause a NULL pointer dereference.
This adds an #ifdef check to avoid the compile-time error, plus
a NULL pointer check before dereferencing THIS_MODULE. It might
be better to find a way to avoid using the module version
altogether.

After a reset, we may immediately begin executing requests on restarting

- Usermode Events
The current events code implemented some data structures (waitqueue, fifo)
that were already implemented in the kernel. The patches below addresses
this issue by replacing them with the standard kernel implementation.
In addition, they simplify allocation of events IDs and memory for the events.
The patches also increase the maximum number of events while maintaining
compatibility with the older userspace library.
- Remove radeon support
Because Kaveri is fully supported in amdgpu and because current and future
versions of userspace libraries will only support amdgpu, we removed radeon
support from kfd. Current users can move to amdgpu while using the same
userspace libraries.
- Various bug fixes and cleanups
* tag 'drm-amdkfd-next-2017-11-02' of git://people.freedesktop.org/~gabbayo/linux: (26 commits)

Because dev_priv is 0-ed it's not currently an issue, but since we
