	Support the following ioctls for CDX devices: - VFIO_DEVICE_GET_IRQ_INFO - VFIO_DEVICE_SET_IRQS This allows user to set an eventfd for cdx device interrupts and trigger this interrupt eventfd from userspace. All CDX device interrupts are MSIs. The MSIs are allocated from the CDX-MSI domain.

2023-06-16	vfio/cdx: add support for CDX bus	Nipun Gupta	1	-0/+8
	vfio-cdx driver enables IOCTLs for user space to query MMIO regions for CDX devices and mmap them. This change also adds support for reset of CDX devices. With VFIO enabled on CDX devices, user-space applications can also exercise DMA securely via IOMMU on these devices. This change adds the VFIO CDX driver and enables the following ioctls for CDX devices: - VFIO_DEVICE_GET_INFO: - VFIO_DEVICE_GET_REGION_INFO - VFIO_DEVICE_RESET Signed-off-by: Nipun Gupta <[email protected]> Reviewed-by: Pieter Jansen van Vuuren <[email protected]> Tested-by: Nikhil Agarwal <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Alex Williamson <[email protected]>
