Subject: [PATCH 0/2] MdeModulePkg/PciBus: Do not enable MemWriteAndInvalidate bit for PCIE
Date: Fri, 25 May 2018 18:02:44 +0800	[thread overview]
Message-ID: <20180525100246.428944-1-ruiyu.ni@intel.com> (raw)

Per PCIE spec, Memory Write and Invalidate is hardwired to 0b so
PciBus driver shouldn't write 1b to it.
Patch #1 cleans up some unnecessary code.

Ruiyu Ni (2):
  MdeModulePkg/PciBus: Remove unnecessary PCIE detection
  MdeModulePkg/PciBus: Do not enable MemWriteAndInvalidate bit for PCIE
