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. Change PCI bus scan algorithm in PciScanBus() to prevent the case where some ARI extended functions may be skipped in the scan loop. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@10644 6f19259b-4bc3-4df7-8a09-765794883524
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

2010-02-241. Correct File header to ## @filelgao4
2. Remove unnecessary .common] postfix on section. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@10052 6f19259b-4bc3-4df7-8a09-765794883524
2010-01-29Remove unnecessary use of FixedPcdxxx() functions and [FixedPcd] INF ↵mdkinney
sections. These should only be used for PCDs that are used to pre-init global variables, pre-init global structures, or size arrays. Do some minor clean ups to INF files git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9868 6f19259b-4bc3-4df7-8a09-765794883524

2010-01-14Fix the issue in MdeModulePkg that mismatch between PCD type and the PCD Lib ↵rsun3
API to get the PCD. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9751 6f19259b-4bc3-4df7-8a09-765794883524

2009-12-24Update resource degrade algorithm in PCI bus driver. (1)If any child device ↵rsun3
has both option ROM and 64-bit BAR, degrade its PMEM64/MEM64 requests in case that if a legacy option ROM image can not access 64-bit resources. (2) If there are both PMEM64 and PMEM32 requests from child devices, which can not be satisfied by a P2P bridge simultaneously, keep PMEM64 and degrade PMEM32 to MEM32. (3) PMEM64/MEM64 are not supported when firmware is in 32-bit mode. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9599 6f19259b-4bc3-4df7-8a09-765794883524
2009-12-24Update PCI bus driver to support non-standard PCI to PCI bridge I/O window ↵rsun3
alignment, such as 2K/1K/512 byte. Feature PCD PcdPciBridgeIoAlignmentProbe is introduced to turn on/off this feature. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9598 6f19259b-4bc3-4df7-8a09-765794883524
