2015-09-15MdeModulePkg: Enhance PCI capability looking up logic to avoid hangRuiyu Ni
Certain PCI device may have capability pointing to itself. Update LocateCapabilityRegBlock() to break when detecting such loop. (Sync patch r18473 from main trunk.)

2015-07-30MdeModulePkg: Enhance PciBusDxe to handle high 32bit of MEM64 BAR returns 0Ruiyu Ni
According to the PCI spec, when software writes all-one to BAR for size probing, the value read back should be 0b1...10...0 after masking the BAR type bits. But in real world, it's possible that certain device returns 0b0...01...10...0 for MEM64 BAR size probing: some bits in the high 32bit may be 0. PciBus driver has the code to handle such case. However, it doesn't handle the case that the high 32bit is totally 0. The patch is to handle the special case.

LocatePciExpressCapabilityRegBlock () doesn't check the return status of Pci.Read(). Certain platform's PciRootBridge.Pci.Read() doesn't support PCIE access causing the CapabilityEntry not updated. If the uninitialized CapabilityEntry equals to a big enough initial value, the while-loop will never end.

2014-06-19The following call tree exposes a bug in the lifetime (ie. too lateAlex Williamson
creation) of PciIoDevice->DevicePath. The bug can be triggered when PciBusDxe is built into OVMF, with qemu/KVM device assignment of a PCI-express device on the default 440FX machine type. OVMF correctly discovers that the device is PCIe and begins probing extended configuration space for the device. The root bridge has no way to access extended config space and correctly errors, sending us into the error reporting chain seen below. It's possible that this error path could also be reproduced on physical hardware when a PCI-to-PCIe bridge is present.

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
2010-12-14Update the PCI bus driver to correctly set the ↵rsun3
EFI_PCI_IO_ATTRIBUTE_EMBEDDED_ROM attribute of PCI IO. Per UEFI spec, this attribute is used to determine if the ROM image is from the ROM BAR or from a platform specific location. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11159 6f19259b-4bc3-4df7-8a09-765794883524
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
2010-11-12Fix bug: The lower 2 bits of Width and stripped, Count will always be ↵vanjeff
multiplied by 1, which will leave Count unchanged. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11043 6f19259b-4bc3-4df7-8a09-765794883524
2010-11-10Fix ICC build break.rsun3
git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11020 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
2010-10-13DuetPkg, MdeModulePkg: Fix several enum comparionsjljusten
These comparisons were not comparing an enum variable with a member of the same enum type. GCC 4.5 generated a warning for these comparison operations. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@10932 6f19259b-4bc3-4df7-8a09-765794883524
