2010-12-28Clean ISA_IO/ISA_IO_16 and VGA_IO/VGA_IO_16 attribute usage in PCI bus ↵rsun3
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
2010-12-14Add special treatment for EFI_PCI_IO_ATTRIBUTE_EMBEDDED_DEVICE and ↵rsun3
EFI_PCI_IO_ATTRIBUTE_EMBEDDED_ROM, because these attributes are only for PCI IO, while not supported by PCI Root Bridge IO. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11165 6f19259b-4bc3-4df7-8a09-765794883524

2010-11-09Some existing PCI adapters with UEFI option ROMs make unaligned requests ↵rsun3
through the PCI I/O Protocol. Add support for unaligned requests in the PCI IO protocol implementation in the PCI Bus driver to be compatible with those UEFI option ROMs. This solution defines a PCD Feature Flag to enabled support for unaligned requests through the PCI I/O Protocol. This flag is disabled by default. Platforms that do want to support such EFI/UEFI drivers that make unaligned PCI I/O requests should enable this feature. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11016 6f19259b-4bc3-4df7-8a09-765794883524
