Message Signaled Interrupts

The QAic Kernel Driver for Linux requires 32 message signaled interrupts (MSI) for best performance. QAic kernel driver does support single MSI configuration but is not recommended. On x86-based host systems, Intel VT-d or IOMMU features must be enabled in the BIOS to enable the required number of MSIs.

For host systems using Intel chipsets, ensure that Intel Virtualization (VT-d) is enabled in the BIOS. For host systems using AMD chipsets, ensure that the IOMMU feature is enabled in the BIOS.
