New Revision: 48851
URL: http://svn.reactos.org/svn/reactos?rev=48851&view=rev
Log:
- Fix PciFindParentPciFdoExtension bug found by sir_richard "Early break would leave
the lock held"
- Fix PciGetHackFlags for setup found by sir_richard "Setup currently doesn't
have a correct registry"
- Fix DriverEntry for setup like PciGetHackFlags
- Fix DriverEntry PciOpenKey check found by sir_richard "PciOpenKey returns a
BOOLEAN, not an NTSTATUS"
- Stop call PciGetAcpiTable found by sir_richard "PciGetAcpiTable is really broken,
can lead to infinite loops, and also corrupts memory. We need to fix stefan's
bugs"
- Implement not root FDO code in PciScanBus and support PCI_HACK_ONE_CHILD
- Implement multiple FDO exist code in PciAddDevice so PCI Bridge support now
- Implement PciAreBusNumbersConfigured for PCI Bridge support
- Hack FDO Start Device by sir_richard "The root FDO does send boot resources if PCIX
is installed properly, this code will be needed"
- Do PCI_BUS_DRIVER_INTERNAL bugcheck by sir_richard "I have hacked KeBugCheckEx to
ignore this for now, until PnP is fixed"
- Implement not root FDO code in PciInitializeArbiters
- Implement PciCacheLegacyDeviceRouting, PciFindPdoByLocation used by
PciAssignSlotResources
- Make PciTranslateBusAddress do the stub work
- PciAssignSlotResources disabled because ReactOS not support IoAssignResources
- Implement PPBridge_ChangeResourceSettings
PCIX driver nearly working now.
