bfd02b3c55 drm/i915: Suppress underruns during DP link retraining 
DP link retraining causes (spurious?) underruns. We can't really avoid
them, except perhaps by doing a full modeset (which has its own underrun
suppression anyway). So let's just hide them.

MST still has its own logic for retrainin, but a bigger hpd handling
cleanup/unification is needed there anyway, so let's leave that be for now.

862372bc8f drm/i915: GMBUS don't need no forcewake 
GMBUS is part of the display engine, and thus has no need for
forcewake. Let's not bother trying to grab it then.

I don't recall if the display engine suffers from system hangs
due to multiple accesses to the same "cacheline" in mmio space.
I hope not since we're no longer protected by the uncore lock
since commit 4e6c2d58ba ("drm/i915: Take forcewake once for
the entire GMBUS transaction")

0853695c3b drm: Add reference counting to drm_atomic_state 
drm_atomic_state has a complicated single owner model that tracks the
single reference from allocation through to destruction on another
thread - or perhaps on a local error path. We can simplify this tracking
by using reference counting (at a cost of a few more atomics). This is
even more beneficial when the lifetime of the state becomes more
convoluted than being passed to a single worker thread for the commit.

v2: Double check !intel atomic_commit functions for missing gets
v3: Update kerneldocs

2ce5179fe8 drm/i915/gtt: Free unused lower-level page tables 
Since "Dynamic page table allocations" were introduced, our page tables
can grow (being dynamically allocated) with address space range usage.
Unfortunately, their lifetime is bound to vm. This is not a huge problem
when we're not using softpin - drm_mm is creating an upper bound on used
range by causing addresses for our VMAs to eventually be reused.

With softpin, long lived contexts can drain the system out of memory
even with a single "small" object. For example:

bo = bo_alloc(size);
while(true)
    offset += size;
    exec(bo, offset);

Will cause us to create new allocations until all memory in the system
is used for tracking GPU pages (even though almost all PTEs in this vm
are pointing to scratch).

Let's free unused page tables in clear_range to prevent this - if no
entries are used, we can safely free it and return this information to
the caller (so that higher-level entry is pointing to scratch).

v2: Document return value and free semantics (Joonas)
v3: No newlines in vars block (Joonas)
v4: Drop redundant local 'reduce' variable
v5: Handle CI fail with enable_ppgtt=2

d209b9c3cd drm/i915/gtt: Split gen8_ppgtt_clear_pte_range 
Let's use more top-down approach, where each gen8_ppgtt_clear_* function
is responsible for clearing the struct passed as an argument and calling
relevant clear_range functions on lower-level tables.
Doing this rather than operating on PTE ranges makes the implementation
of shrinking page tables quite simple.

v2: Drop min when calculating num_entries, no negation in 48b ppgtt
check, no newlines in vars block (Joonas)

4c494a5769 drm/i915: Fix mismatched INIT power domain disabling during suspend 
Currently the display INIT power domain disabling/enabling happens in a
mismatched way in the suspend/resume_early hooks respectively. This can
leave display power wells incorrectly disabled in the resume hook if the
suspend sequence is aborted for some reason resulting in the
suspend/resume hooks getting called but the suspend_late/resume_early
hooks being skipped. In particular this change fixes "Unclaimed read
from register 0x1e1204" on BYT/BSW triggered from i915_drm_resume()->
intel_pps_unlock_regs_wa() when suspending with /sys/power/pm_test set

e473405783 drm/i915/gvt: vGPU workload scheduler 
This patch introduces the vGPU workload scheduler routines.

GVT workload scheduler is responsible for picking and executing GVT workload
from current scheduled vGPU. Before the workload is submitted to host i915,
the guest execlist context will be shadowed in the host GVT shadow context.
the instructions in guest ring buffer will be copied into GVT shadow ring
buffer. Then GVT-g workload scheduler will scan the instructions in guest
ring buffer and submit it to host i915.

28c4c6ca7f drm/i915/gvt: vGPU workload submission 
This patch introduces the vGPU workload submission logics.

Under virtualization environment, guest will submit workload through
virtual execlist submit port. The submitted workload load will be wrapped
into an gvt workload which will be picked by GVT workload scheduler and
executed on host i915 later.
