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

2010-12-14Update the PCI bus driver to correctly set the ↵rsun3

2010-11-22The PCI HotPlug Init Protocol returns a list of Root HPC, but it is possible ↵rsun3
that some HPCs in the list are not found during PCI enumeration. In this case, the PCI HotPlug Init Protocol.InitializeRootHpc() will not be called for the un-found HPCs. However, in AllRootHPCInitialized(), all reported HPCs are checked to see if it has been initialized, so TIME_OUT happens. This check-in fix the issue by adding a flag to indicate if a HPC is found during PCI enumeration or not. This check-in also adds a debug message if any found HPC failed with initialization. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11081 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
2010-11-08Per the UEFI spec, if a PCI controller is a P2P bridge, then the I/O, Memory ↵rsun3
and Bus Master bits in the Command register of the PCI configuration header should be placed in the enabled state by the PCI Bus driver. But current PCI bus driver has a bug that if a P2P bridge has no child devices detected during enumeration, the bits won’t be set. This may impact PCI hot plug capable bridges because the OS may re-assign resources for them causing the reserved resource by the firmware will be overwritten. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11013 6f19259b-4bc3-4df7-8a09-765794883524

2010-07-13Fix bugs in the PCI bus driver to support SR-IOV.rsun3
1. Expand the type of Offset in the _PCI_BAR structure from UINT8 to UINT16, because a VF BAR’s offset may be >= 0x100; 2. Enable ARI Capable Hierarchy for SR-IOV devices at earlier time because FirstVFOffset and VFStride of a SR-IOV device may change after its ARI Capable Hierarchy is set; 3. Change type of PcdSrIovSupport, PcdAriSupport, PcdMrIovSupport from FeatureFlag to [FixAtBuild, PcdDynamics], which allows SR-IOV/MR-IOV/ARI feature can be turn on/off dynamically, typically via a setup option. 4.

2010-05-07Fix bug in PciHostBridgeEnumerator().mdkinney
A linked list is created for the list of PCI Root Bridges in the platform. This list is then traversed to enumerate each PCI Root Bridge. After enumeration, the RootBridgeDev is destroyed, but it was not removed from the linked list before it was destroyed. This left the linked list of PCI Root Bridges in a bad state, specially if memory is cleared on frees, or the freed buffer was reallocated. The fix is to remove the node from the linked list before the RootBridgeDev is destroyed. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@10463 6f19259b-4bc3-4df7-8a09-765794883524
