charset="us-ascii" Content-Transfer-Encoding: quoted-printable Dear developers, While browsing the KabylakeSiPkg code, I noticed that 64-bit registers are = read directly via MmioRead64() as there is no PciRead64() function. Is there a specific reason there are no PciRead64() and PciExpressRead64() = functions or were they simply not needed previously? Thanks and regards, Marvin.
