We are happy to announce a new version of the partitioning hypervisor Jailhouse. As we skipped the Autumn release, this one has a larger change list with 178 commits (225 files changed, 7814 insertions, 3307 deletions):
- New targets: - Marvell ESPRESSOBin - emtrion emCON-RZ/G1E and emCON-RZ/G1M - QEMU ARM64 virtual machine - Cross-arch changes: - dual-licensed inmate library (GPLv2 or 2-clause BSD), for reuse in whatever guest code you like - relocatable inmates, defaulting to start address 0, also on x86 - optional timeout for hypervisor-guest protocol used via Communication Region - ARM / ARM64: - support for GICv3 on ARM64, along with a number of fixes for this GIC model - fix for stuck target after jailhouse shutdown due to lost IRQs - runtime choice of GIC version (v2 or v3) - x86: - ignore invalid IOAPIC accesses to simplify guest support, enabling limited usage in non-root Linux cells - proper reset of IOAPIC pins on cell startup and destruction - support for PAE addressing mode in guests - extended set of supported MMIO instructions - pass pre-calibrated TSC and APIC frequencies to inmates, picking the values up from the root cell or the system configuration - enhanced and versioned setup interface to non-root Linux cells - prevent denial-of-service attacks via debug port 0x80
You can download the new release from
https://github.com/siemens/jailhouse/archive/v0.8.tar.gz
then follow the README.md for first steps on recommended evaluation platforms and check the tutorial session from ELC-E 2016 [1][2]. Drop us a note on the mailing list if you run into trouble.
There were and are also a number of activities outside of the main repository. Most noteworthy are ongoing work to add x86 non-root cell support into upstream Linux [3], the official integration of Jailhouse support into the Zephyr RTOS [4], and first Yocto recipes for the Banana Pi ARM target [5].
Thanks to all the contributors, to the core as well as these supplementary efforts!
Happy new year, Jan
