VMM BSP on realview-pb-a8
|
||||
|
||||
This is a demo program that run RT-Thread VMM(Virtual Machine Module) on
|
||||
the single core RealView-PB-A8.
|
||||
|
||||
To compile it, you need buildroot and a linux 3.8.x source tree. You should
|
||||
build the patched Linux kernel and builroot before building the VMM. This
|
||||
directory has a "mk.sh" helper script to build both the RT-Thread, Linux kernel
|
||||
module and the ramdisk.
|
||||
|
||||
Linux console is serial0 and RT-Thread console is serial1.

Subject: [PATCH 2/2] arm: gic: correct the cpu map on gic_raise_softirq for UP
|
||||
system
|
||||
|
||||
The CPU mask on UP system is empty, so if we want to raise softirq on UP
|
||||
system, designate CPU0 to the map.
|
||||
|
||||
Maybe the more correct way is to fix the gic_get_cpumask.
