2012-06-01PcAtChipsetPkg/PciHostBridgeDxe: Improve KVM FIFO I/O read/write performancejljusten
KVM can substantially boost the speed of the rep insb/insw/insl and rep outsb/outsw/outsl instructions by transferring up to a page of data per VM trap. This change adds assembly handling of the PCI Host Bridge I/O FIFO Reads and Writes.

driver/PCI host bridge drivers/LPC/VGA device drivers. 1. Fix the incorrect definition of EFI_PCI_IO_ATTRIBUTE_VGA_IO_16 (does not conform to the UEFI spec) in PciIo.h. 2. Add missing definitions of ISA and VGA IO attributes in PCI Root Bridge IO protocol. 3. Improve the algorithm in the PCI bus driver to get PCI platform policy from PCI Platform Protocol and PCI Override Protocol. 4. Update the PCI bus driver to use the PCI platform policy to determine the supported attributes that are returned by the EFI_PCI_IO_PROTOCOL.Attributes() function. This is required by the PI spec. 5. Add a backward compatibility workaround for PCI VGA drivers in Option ROM, which typically sets VGA_IO without checking supported attributes. 6. Update the PCI host bridge driver in PcAtChipsetPkg to report VGA_IO_16 and ISA_IO_16 instead of VGA_IO/ISA_IO attributes. Modern chipsets don’t have hardware capability to control 10-bit or 16-bit decoding for ISA/VGA aliases. 7. Update LPC/VGA device drivers to check supported attributes of VGA_IO/VGA_IO_16 or ISA_IO/ISA_IO_16. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11204 6f19259b-4bc3-4df7-8a09-765794883524
