I've been asked to put together a git branch with the latest versions of various dependencies (mach-virt, cpu-host, Mian's patchset) for aarch64 kvm control support in qemu. You can find it at: git://git.linaro.org/people/pmaydell/qemu-arm.git aarch64-kvm pointy-clicky version at: https://git.linaro.org/gitweb?p=people/pmaydell/qemu-arm.git;a=shortlog;h=refs/heads/aarch64-kvm (NB: Amazon webservices outage this afternoon, so possibly the git repo might be unaccessible; if so retry later.) This is intended for testing purposes, setting up continuous integration loops, etc; it's nowhere near production or upstream quality yet. I'm not going to post all the patches here because the ones that are ready to go upstream or nearly so have all appeared before. The branch contains: device_tree.c: Terminate the empty reservemap in create_device_tree() hw/arm/boot: Allow boards to provide an fdt blob hw/arm: Add 'virt' platform -- these are the mach-virt patches I posted this week default-configs: Add config for aarch64-softmmu -- the default-config which is the only thing which wasn't committed from the aarch64-preparation patchset target-arm: Don't hardcode KVM target CPU to be A15 target-arm: Provide '-cpu host' when running KVM -- "-cpu host" support for 32 bit targets. Basically the patches I posted a while back, rebased and fiddled a bit to match the proposed new kernel API where we ask it for its preferred target and use that answer to do the vcpu init. At the moment we rely on the fallback code for kernels which don't have the ioctl; there's an obvious TODO in the code for when the ioctl arrives. hw/arm/virt: Support -cpu host -- make mach-virt treat '-cpu host' like an A15 linux-headers: update to 3.11 -- needed for the AArch64 headers; this patch will go upstream via the kvm queue shortly I expect AARCH64: Add aarch64 CPU initialization, get and put registers support -- quick rebase of a minimal subset of Mian's patches aarch64: fixup: cpu host for 64 bit -- ...and a hacky addition of 64 bit "-cpu host" by me AARCH64: Add boot support for aarch64 processor -- another patch from Mian hw/arm/virt: Support 64 bit -cpu host -- we tell the kernel we're a v8 but still use the A15's private peripherals. need to check if this is really sane. configure: Enable KVM for aarch64 host/target combination -- turn it all on. The lower end of the patchstack is solid, things get a bit iffier and in need of cleanup as we go up. I've put notes in a few commit messages about things that should be done. This works for me to boot a simple v8 single CPU guest with ./qemu-system-aarch64 -M virt -cpu host -kernel ./Image -append 'rdinit=/bin/sh init=/bin/sh console=ttyAMA0,38400 keep_bootcon' -enable-kvm -display none -serial stdio on a Foundation Model. No SMP support as I didn't take that patch from the OVS tree. thanks -- PMM _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/cucslists/listinfo/kvmarm
