In addition to the SUSE work we have fixed numerous edge cases and finished off classes of instructions. All instructions have been verified with Peter's RISU random instruction testing tool. I have also built and run many packages as well as built gcc and passed most of the aarch64 specific tests. I've tested against the following aarch64 rootfs: * SUSE [2] * Debian [3] * Ubuntu Saucy [4] In my tree the remaining insns that the GCC aarch64 tests need to implement are: FRECPE FRECPX CLS (2 misc variant) CLZ (2 misc variant) FSQRT FRINTZ FCVTZS Which I'm currently working though now. However for most build tasks I expect the instructions in master [1] will be enough. If you want the latest instructions working their way to mainline you are free to use my tree [5] which currently has: * Additional NEON/SIMD instructions * sendmsg syscall * Improved helper scripts for setting up binfmt_misc * The ability to set QEMU_LOG_FILENAME to /path/to/something-%d.log - this is useful when tests are failing N-levels deep as %d is replaced with the pid Feedback I'm interested in ========================== * Any instruction failure (please include the log line with the unsupported message) * Any aarch64 specific failures (i.e. not generic QEMU threading flakeiness). If you need to catch me in real time I'm available on #qemu (stsquad) and #linaro-virtualization (ajb-linaro). Many thanks to the SUSE guys for getting the aarch64 train rolling. I hope your happy with the final result ;-) Cheers, -- Alex Bennée QEMU/KVM Hacker for Linaro [1] git://git.qemu.org/qemu.git master [2] http://download.opensuse.org/ports/aarch64/distribution/13.1/appliances/openSUSE-13.1-ARM-JeOS.aarch64-rootfs.aarch64-1.12.1-Build32.1.tbz [3] http://people.debian.org/~wookey/bootstrap/rootfs/debian-unstable-arm64.tar.gz [4] http://people.debian.org/~wookey/bootstrap/rootfs/saucy-arm64.tar.gz [5] https://github.com/stsquad/qemu/tree/ajb-a64-working [6] https://github.com/susematz/qemu/tree/aarch64-1.6
