[edk2] [PATCH V2 0/2] Improve IntelVTd performance.

Posted by Jiewen Yao 6 years, 8 months ago

=========== V2 =============
I found CacheLineFlush() is already defined in CacheMaintenanceLib.

Drop the CpuLib update, but use in CacheMaintenanceLib directly.

=========== V1 =============
This series patch replace WBINVD with CLFlush
in IntelVTdDxe driver, which improves boot performance.

This patch is validated on Intel Kabylake generation.

Jiewen Yao (2):
  IntelSiliconPkg/dsc: Add CacheMaintenanceLib.
  IntelSiliconPkg/IntelVTdDxe: Improve performance.
