[Qemu-devel] [PATCH v4 04/15] target-arm: Add vexpress machine secure property |
Date: |
Mon, 15 Dec 2014 17:09:41 -0600 |
Add "secure" Vexpress machine specific property to allow override of the
default secure state configuration. By default, when using the QEMU
-kernel command line argument, Vexpress machines boot into NS/SVC. When using
the QEMU -bios command line argument, Vexpress machines boot into S/SVC.
The secure state can be changed from the default specifying the secure
state as a machine property. For example, the below command line would disable
security extensions on a -kernel Linux boot:
aarch64-softmmu/qemu-system-aarch64
-machine type=vexpress-a15,secure=off
-kernel ...

v1 -> v2
- Adapt the machine secure property to Marcel's new dynamic registration
- Change the default machine secure property to true (on).
v3 -> v4
- Revise machine secure property description
