Zhenyu Wang 0fac21e7e9 drm/i915/gvt: properly access enabled intel_engine_cs
Switch to use new for_each_engine() helper to properly access
enabled intel_engine_cs as i915 core has changed that to be
dynamic managed. At GVT-g init time would still depend on ring
mask to determine engine list as it's earlier.

Ville Syrjälä 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.

Michał Winiarski 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

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)

Imre Deak 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

intel_pps_unlock_regs_wa() when suspending with /sys/power/pm_test set
