This patch series adds some infrastructure to kvmtool to allow a BE guest to use virtio-mmio on a LE host, provided that the architecture actually supports such madness. Not all the backend have been converted, only those I actually cared about. Converting them is pretty easy though, and will be done if the method is deemed acceptable. This has been tested on both arm and arm64 (I use this on a daily basis to test BE code). The corresponding kernel changes have all been merged. Also available at: git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git kvm-arm64/kvmtool-be-on-le >From v3: - Only patch 9/9 changed: * Handle access comming from EL0 in AArch64 mode * Added comment about SETEND in AArch32 mode * Fixed commit message >From v2 (never posted): - Fixed tons of bugs (config space) - Fixed TAP networking >From v1: - Gave up on the virtio extension after the push back from the PPC guys. Instead, we snapshot the endianness of the vcpu when it tries to reset the device. A bit ugly, but doesn't require any change on the kernel side.
