menu "PCI Endpoint"
config PCI_ENDPOINT
bool "PCI Endpoint Support"
depends on HAVE_PCI
help
Enable this configuration option to support configurable PCI
endpoint. This should be enabled if the platform has a PCI
controller that can operate in endpoint mode.
Enabling this option will build the endpoint library, which
includes endpoint controller library and endpoint function
library.
If in doubt, say "N" to disable Endpoint support.
config PCI_ENDPOINT_CONFIGFS
bool "PCI Endpoint Configfs Support"
depends on PCI_ENDPOINT
select CONFIGFS_FS
help
This will enable the configfs entry that can be used to
configure the endpoint function and used to bind the
function with an endpoint controller.
config PCI_ENDPOINT_MSI_DOORBELL
bool "PCI Endpoint MSI Doorbell Support"
depends on PCI_ENDPOINT && GENERIC_MSI_IRQ
help
This enables the EP's MSI interrupt controller to function as a
doorbell. The RC can trigger doorbell in EP by writing data to a
dedicated BAR, which the EP maps to the controller's message address.
