Just use a simple {} to zero initialize arrays/structs instead
of the hodgepodge of stuff we are using currently.

f645d22b93 drm/i915/gvt: remove unused variable gma_bottom in command parser
Remove unused variable gma_bottom in scan_workload() and scan_wa_ctx().
commit be1da7070a ("drm/i915/gvt: vGPU command scanner") introduces
gma_bottom in several functions to calculate the size of the command
buffer. However, some of them are set but actually unused.

When compiling the code with ccflags -Wunused-but-set-variable, gcc
throws warnings.

Remove unused variables to avoid the gcc warnings. Tested via compiling
the code with ccflags -Wunused-but-set-variable.

acc855d301 drm/i915/display: add intel_display_limits.h for key enums
Move a handful of key enums to a new file intel_display_limits.h. These
are the enum types, and the MAX/NUM enumerations within them, that are
used in other headers. Otherwise, there's no common theme between them.

Replace intel_display.h include with intel_display_limit.h where
relevant, and add the intel_display.h include directly in the .c files
where needed.

Since intel_display.h is used almost everywhere in display/, include it
from intel_display_types.h to avoid massive changes across the
board. There are very few files that would need intel_display_types.h
but not intel_display.h so this is neglible, and further cleanup between
these headers can be left for the future.

Overall this change drops the direct and indirect dependencies on
intel_display.h from about 300 to about 100 compilation units, because
we can drop the include from i915_drv.h.

801543b259 drm/i915: stop including i915_irq.h from i915_trace.h
Turns out many of the files that need i915_reg.h get it implicitly via
{display/intel_de.h, gt/intel_context.h} -> i915_trace.h -> i915_irq.h
-> i915_reg.h. Since i915_trace.h doesn't actually need i915_irq.h,
makes sense to drop it, but that requires adding quite a few new
includes all over the place.

Prefer including i915_reg.h where needed instead of adding another
implicit include, because eventually we'll want to split up i915_reg.h
and only include the specific registers at each place.

Also some places actually needed i915_irq.h too.

93d9e0453e drm/i915/gvt: Use intel_engine_mask_t for ring mask
When i915 adds additional PVC blitter instances (in an upcoming patch),
the definition of VECS0 will change from bit(10) to bit(18), causing
GVT's R_ALL mask to overflow the u16 storage that's currently used.
Let's replace the u16 with an intel_engine_mask_t to ensure we avoid
this.

202b1f4c12 drm/i915/gt: Move engine registers to their own header
Let's continue breaking up and cleaning up the massive i915_reg.h file
by moving all registers that are defined in relation to an engine base
to their own header.

There are probably a bunch of other "engine registers" that we haven't
moved yet (especially those that belong to the render engine in the
0x2??? range), but this is a relatively straightforward first step.

fbb2bdd22a drm/i915/gvt: fix uninitialized return in intel_gvt_update_reg_whitelist()
Smatch found an uninitialized variable bug in this code:

    drivers/gpu/drm/i915/gvt/cmd_parser.c:3191 intel_gvt_update_reg_whitelist()
    error: uninitialized symbol 'ret'.

The first thing that Smatch complains about is that "ret" isn't set if
we don't enter the "for_each_engine(engine, &dev_priv->gt, id) {" loop.
Presumably we always have at least one engine so that's a false
positive.

But it's definitely a bug to not set "ret" if i915_gem_object_pin_map()
fails.

Let's fix the bug and silence the false positive.

Logical Context is actually a big batch buffer consisting of multiple
LRI commands + saved registers. It comprises Ring Context (the first

are command accessible, and safe to execute in VM Context.
However, not all of them are currently tracked in existing register

then scan the dummy Engine context to update whitelist dynamically. Based
on updated list, later patches will audit future VM Engine Contexts to
disallow undesired LRIs (if out of what hardware generates).

i915_gem_ww_ctx is used to lock all gem bo's for pinning and memory
eviction. We don't use it yet, but lets start adding the definition

To use it, we have to pass a non-NULL ww to gem_object_lock, and don't
unlock directly. It is done in i915_gem_ww_ctx_fini.

bec3df930f drm/i915/gvt: Support PPGTT table load command
The PPGTT in context image can be overridden by LRI cmd with another
PPGTT's pdps. In such case, the load mm is used instead of the one in
the context image. So we need to load its shadow mm in GVT and replace
ppgtt pointers in command.

This feature is used by guest IGD driver to share gfx VM between
different contexts. Verified by IGT "gem_ctx_clone" test.

v4:
- consolidate shadow mm handlers (Yan)
- fix cmd shadow mm pin error path

v3: (Zhenyu Wang)
- Cleanup PDP register offset check
- Add debug check for guest context ppgtt update
- Skip 3-level ppgtt guest handling code. The reason is that all
  guests now use 4-level ppgtt table and the only left case for
  3-level table is ancient aliasing ppgtt case. But those guest
  kernel has no use of PPGTT LRI command. So 3-level ppgtt guest
  for this feature becomes simply un-testable.

v2: (Zhenyu Wang)
- Change to list for handling possible multiple ppgtt table loads
  in one submission. Make sure shadow mm is to replace for each one.

db19c724cb drm/i915/gvt: Make WARN* drm specific where drm_priv ptr is available
drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*

The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.
