Mbigen means: message based interrupt generator.
|
|
|
|
MBI is kind of msi interrupt only used on Non-PCI devices.
|
|
|
|
To reduce the wired interrupt number connected to GIC, Hisilicon designed
|
|
mbigen to collect and generate interrupt.
|
|
|
|
Non-pci devices can connect to mbigen and generate the interrupt by writing
|
|
ITS register.
