This series of optimization can save about 2MB memory, speed up guest
boot time by ~500ms, lower the hash talbe conflict from 140+ to ones
digit.
Changbin Du (6):
drm/i915/gvt: Optimize MMIO register handling for some large MMIO
blocks
drm/i915/gvt: Cleanup struct intel_gvt_mmio_info
drm/i915/gvt: Make mmio_attribute as type u8 to save 1.5MB memory
drm/i915/gvt: Make the MMIO attribute wrappers be inline
drm/i915/gvt: Add helper for tuning MMIO hash table
drm/i915/gvt: Tuning the size of MMIO hash lookup table to 2048
