Hi,
this series adds PSCI support for ARM inmates.
A new psci-demo inmate boots a secondary CPU and issues SGIs back and forth.
After some rounds, it shuts down the secondary CPU again.
Tested in Jailhouse on a TK1 and TX1.
Tested on bare-metal on a TK1. (Note: U-Boot must not boot in HYP mode)
This series requires my inmate-decouple series.
Not working:
- PSCI support on bare-metal ARM64 without Jailhouse (WIP, I have some
problems with activating interrupts on bare-metal, as u-boot boots into
EL2...)
- Offlining a CPU currently does not decrease cpus_online
Find the series (on top of inmate-decouple on top of next) here:

Changes since v1:
- Fix SGI CPU ID reinjection for GICv2
- Initialise stacks as proposed by Jan
- Remove unnecessary patch
Changes since the first RFC series:
- Jan alread removed virt_id. This made my approach of removing it
obselete. Removed those patches
- Removed the TX1 non-root Linux inmate support patches, sent them
separately
- Switched to dual-license header
Ralf Ramsauer (16):
