2012-11-20oslib-posix: Align to permit transparent hugepages on ARM Linuxkvm-arm-v14Peter Maydell
ARM Linux (like x86-64 Linux) can use transparent hugepages for KVM if memory blocks are 2MiB aligned; set QEMU_VMALLOC_ALIGN accordingly. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2012-11-20configure: Enable KVM on ARMPeter Maydell
Enable KVM on ARM hosts, now that all the necessary components for it exist. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2012-11-20hw/kvm/arm_gic: Implement support for KVM in-kernel ARM GICPeter Maydell
Implement support for using the KVM in-kernel GIC for ARM. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2012-11-20target-arm: Use MemoryListener to identify GIC base address for KVMPeter Maydell
When using an in-kernel GIC with KVM, we need to tell the kernel where the GIC's memory mapped registers live. Do this by registering a MemoryListener which tracks where the board model maps the A15's private peripherals, so we can finish the GIC initialisation when the GIC is actually mapped. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2012-11-20hw/arm_gic: Add presave/postload hooksPeter Maydell
Add presave/postload hooks to the ARM GIC common base class. These will be used by the KVM in-kernel GIC subclass to sync state between kernel and userspace when migrating. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Andreas Färber <afaerber@suse.de>
2012-11-20ARM KVM: save and load VFP registers from kernelPeter Maydell
Add support for saving and restoring VFP register state from the kernel. This includes a check that the KVM-created CPU has full VFP support (as the TCG Cortex-A15 model always does), since for the moment ARM QEMU doesn't have any way to tweak optional features on created CPUs. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2012-11-20ARM: KVM: Add support for KVM on ARM architectureChristoffer Dall
Add basic support for KVM on ARM architecture. Signed-off-by: Christoffer Dall <cdall@cs.columbia.edu> [PMM: Minor tweaks and code cleanup, switch to ONE_REG] Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2012-11-20linux-headers: Add ARM KVM headers (not for upstream)Peter Maydell
This commit adds the ARM KVM headers. This is not to go to QEMU upstream -- the correct path there is that the KVM code will be committed to a mainline upstream kernel, and then upstream QEMU can do a bulk header update from the upstream kernel, which will allow us to drop this temporary commit. This is the result of running update-headers on Christoffer's kvm-arm-v14-vgic-timers branch (commit 68d116f). This commit currently also includes some non-ARM header changes which hopefully will have made it into QEMU upstream by the time we submit this for merging.

Commit 32761257c0b9fa7ee04d2871a6e48a41f119c469 enabled qemu_ld/st optimization unconditionally for some hosts. The TCG interpreter still does not support this kind of optimization.

2012-11-18build: replace weak symbols with a static libraryPaolo Bonzini
Weak symbols were a nice idea, but they turned out not to be a good one. Toolchain support is just too sparse, in particular llvm-gcc is totally broken. This patch uses a surprisingly low-tech approach: a static library. Symbols in a static library are always overridden by symbols in an object file. Furthermore, if you place each function in a separate source file, object files for unused functions will not be taken in. This means that each function can use all the dependencies that it needs (especially QAPI stuff such as error_setg). Thus, all stubs are placed in separate object files and put together in a static library. The library then is linked to all programs.

2012-11-16virtio-rng: add rate limiting supportAnthony Liguori
This adds parameters to virtio-rng-pci to allow rate limiting the entropy a guest receives. An example command line: $ qemu -device virtio-rng-pci,max-bytes=1024,period=1000 Would limit entropy collection to 1Kb/s. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-11-16virtio-rng: hardware random number generator deviceAmit Shah
The Linux kernel already has a virtio-rng driver, this is the device implementation. When the guest asks for entropy from the virtio hwrng, it puts a buffer in the vq. We then put entropy into that buffer, and push it back to the guest.

2012-11-16rng-random: add an RNG backend that uses /dev/random (v3)Anthony Liguori
