Subject: drm/i915/vgpu: improve vgpu abstractions
Git-commit: 9e859eb9d0f5e3ca553b53c4de149f0988814ad7
Patch-mainline: v5.7-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
Add intel_vgpu_register() abstraction, rename i915_detect_vgpu() to
intel_vgpu_detect() to match other function naming, un-inline
intel_vgpu_active(), intel_vgpu_has_full_ppgtt() and
intel_vgpu_has_huge_gtt() to reduce header interdependencies.
The i915_vgpu.[ch] filename and intel_vgpu_ prefix discrepancy remains.
