Subject: [PATCH 0/4] *** BaseIoFifoLib ***
Date: Wed, 4 Jan 2017 17:07:49 -0600 [thread overview]
Message-ID: <1483571273-11187-1-git-send-email-leo.duran@amd.com> (raw)
The UefiCpuPkg/CpuIo2Dxe driver and the QemuCfgLib library have duplicate
implementations of I/O Fifo routines. The patch series moves the I/O Fifo
routines into a common BaseIofifoLib library supporting IA32 and X64
architectures under MdePkg.
The intent of this patch series is twofold:
1) Consolidate I/O Fifo routines into a common BaseIofifoLib library.
2) Allow override of BaseIofifoLib for specific platform implementations.
For example, the OVMF package can provide its own version of BaseIoFifoLib
to support Secure Encrypted Virtualization (SEV) guests, since SEV does not
support string I/O instructions (rep ins/outs), and requires unrolled loops
of single in/out instructions.
Leo Duran (4):
