Last change on this file since 92473 was 89620, checked in by vboxsync, 4 years ago

Intel IOMMU: bugref:9967 Allow PDMIoApicSetEoi operation to be queued to ring-3 if I/O APIC isn't available in R0.
This key change is taking the PDM lock such that it doesn't fail (VINF_SUCCESS instead of VINF_IOM_R3_MMIO_WRITE for rcBusy, which wouldn't have worked anyway when called via APICHvSetEoi for instance).
Also cleaned up the prototype of PDMIoApicSendMsi a bit (use PVMCC instead of PPDMDEVINS).
