New Revision: 48118
URL: http://svn.reactos.org/svn/reactos?rev=48118&view=rev
Log:
Last code in PciScanBus: call to PciGetfunctionLimits now implement (call
PcipGetfunctionLimits if PciSkipThisFunction say no)
PcipGetfunctionLimits support PCI_HACK_CRITICAL_DEVICE and PCI Debug Device by use IPI
code (PciExecuteCriticalSystemRoutine implement)
PciConfigurators table define for Device, PCI-to-PCI (PP) Bridge plus CardBus Bridge but
all configurator stub now
Configurator chain: Init (Massage) -> [WRITE INIT] (PciWriteLimitsAndRestoreCurrent)
-> Restore -> SaveLimit -> SaveCurrent
Support ExpectedWritebackFailure
Fix bug in PciApplyHacks (found by me testing sir_richard code)
Now pass 7000 SLOC ^_^;~ Good night!
