The MSIs are allocated from theCDX-MSI domain.Signed-off-by: Nipun Gupta <nipun.gupta@amd.com>Reviewed-by: Pieter Jansen van Vuuren <pieter.jansen-van-vuuren@amd.com>Link: https://lore.kernel.org/r/20240423111021.1686144-2-nipun.gupta@amd.comSigned-off-by: Alex Williamson <alex.williamson@redhat.com> List of files: /linux-6.15/drivers/vfio/cdx/Makefile Tue, 23 Apr 2024 11:10:21 +0000 Nipun Gupta <nipun.gupta@amd.com> http://172.16.0.5:8080/history/linux-6.15/drivers/vfio/cdx/Makefile#234489ac vfio/cdx: add support for CDX busvfio-cdx driver enables IOCTLs for user space to queryMMIO regions for CDX devices and mmap them. This changealso adds support for reset of CDX devices. With VFIOenabled on CDX devices, user-space applications can alsoexercise DMA securely via IOMMU on these devices.This change adds the VFIO CDX driver and enables the followingioctls for CDX devices: - VFIO_DEVICE_GET_INFO: - VFIO_DEVICE_GET_REGION_INFO - VFIO_DEVICE_RESETSigned-off-by: Nipun Gupta <nipun.gupta@amd.com>Reviewed-by: Pieter Jansen van Vuuren <pieter.jansen-van-vuuren@amd.com>Tested-by: Nikhil Agarwal <nikhil.agarwal@amd.com>Link: https://lore.kernel.org/r/20230531124557.11009-1-nipun.gupta@amd.comSigned-off-by: Alex Williamson <alex.williamson@redhat.com> List of files: /linux-6.15/drivers/vfio/cdx/Makefile Wed, 31 May 2023 12:45:57 +0000 Nipun Gupta <nipun.gupta@amd.com>
