REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3708 The original code will cause FWTS V21.08.00 testing failed. spcr: SPCR PC-AT compatible IRQ 0xff is invalid spcr: SPCR PCI flags compatibility bit 0 is 0, expecting 1 for PCI device Now modify the SpcrAcpi for following: 1. Disable the support of PC-AT compatible IRQ support. Now only support IO-APIC interrupt type. 2. Set irq to 0. 3. Set the GSI to the value read from PCI device cfg space 0x3C. 4. Set PCI Flags to 1.
