Subject: [PATCH] MdePkg/PciExpress21.h: Fix the PCIe industry standard registers
Date: Mon, 22 Jul 2019 11:56:27 +0530 [thread overview]
Message-ID: <20190722062627.12276-1-ashraf.javeed@intel.com> (raw)
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=2007
The PCIe Device capability register #2 (PCI_REG_PCIE_DEVICE_CAPABILITY2)
needs to be upgraded for the PCI features like - LN system CLS, 10b Tag
completer/requester register fields, emergency power reduction support
and initialization requirement, and FRS support.
The PCIe Device Control register #2 (PCI_REG_PCIE_DEVICE_CONTROL2) needs
to be upgraded for the - emergency power reduction request enabling and
also the 10b Extended Tag enabling.
Needs macro definitions for all the ranges of Maximum Payload Sizes and
Maximum Read Request Sizes defined
Needs macro definitions for all the ranges of Completion Timeout range
needs to be defined.
