Subject: [PATCH 0/4] Cover: Support mbigen msi interrupt controller
Date: Sat, 30 May 2015 11:19:00 +0800 [thread overview]
Message-ID: <55692C24.107@huawei.com> (raw)
This patch set is applied to supprot the mbigen device.
Mbigen means message based interrupt generator.
It locate in ITS or out side of ITS.
In fact, mbigen is a kind of interrupt controller collects
the irq form Non-PCI devices and generate msi interrupt.
Hisilicon designed mbigen to reduce the wired interrupt
number connected to GIC.
In these patches, the interrupts from Non-PCI devices are
named as MBI to distiguish between legacy MSI interrupt from
PCI devices.
As a MSI interrupt controller, the mbigen is used as a child
domain of MSI domain just like PCI devices.
So,in order to support the mbigen interrupt controller, the
msi.c and its-gic-v3-its.c are changed.
Ma Jun (4):
Add mbigen driver to support mbigen interrupt controller
Change msi to support the Mbigen interrupt
Change arm-gic-its to support the Mbigen interrupt
