0e439ba3 - cdx: add MSI support for CDX bus

Mon, 26 Feb 2024 08:28:16 +0000

cdx: add MSI support for CDX busAdd CDX-MSI domain per CDX controller with gic-its domain asa parent, to support MSI for CDX devices. CDX devices allocateMSIs from the CDX domain. Also, introduce APIs to alloc and freeIRQs for CDX domain.In CDX subsystem firmware is a controller for all devices andtheir configuration. CDX bus controller sends all the write_msi_msgcommands to firmware running on RPU and the firmware interfaces withactual devices to pass this information to devicesSince, CDX controller is the only way to communicate with the Firmwarefor MSI write info, CDX domain per controller required in contrast tohaving a CDX domain per device.Co-developed-by: Nikhil Agarwal Signed-off-by: Nikhil Agarwal Co-developed-by: Abhijit Gangurde Signed-off-by: Abhijit Gangurde Signed-off-by: Nipun Gupta Reviewed-by: Pieter Jansen van Vuuren Reviewed-by: Thomas Gleixner Tested-by: Nikhil Agarwal Link: https://lore.kernel.org/r/20240226082816.100872-1-nipun.gupta@amd.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/cdx/controller/Kconfig
