[ANNOUNCE] Jailhouse 0.8 released

[Jan Kiszka <jan.kiszka@web.de>]

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
