This required several new patches to address the following issues: 1. Tests that do not negotiate features (non-compliant!) 2. Tests that access configuration space before feature negotiation (non-compliant!) 3. Tests that set up virtqueues before feature negotiation (non-compli= ant!) 4. vring accesses require byte-swapping when VIRTIO 1.0 is used with a big-endian guest because the qtest_readX/writeX() API automatically converts to guest-endian 5. VIRTIO 1.0 has an additional FEATURES_OK step during Device Initialization * Change uint8_t bar_idx to int [Thomas] * Document qpci_find_capability() [Thomas] * Every commit tested with arm, ppc64, and x86_64 targets using: git rebase -i origin/master -x 'make tests/qos-test && QTEST_QEMU_BINARY=3Dppc64-softmmu/qemu-system-ppc64 tests/qos-test && QTEST_QEMU_BINARY=3Dx86_64-softmmu/qemu-system-x86_64 tests/qos-test' QTEST_QEMU_BINARY=3Darm-softmmu/qemu-system-arm tests/qos-test' v2: * Fix checkpatch.pl issues, except MAINTAINERS file warning. libqos alr= eady has maintainers and the new virtio-pci-modern.[ch] files don't need ex= tra entries since they are already covered by the existing libqos/ entry. New VIRTIO devices are Non-Transitional. This means they only expose the VIRTIO 1.0 interface, not the Legacy interface. The libqos only supports Legacy and Transitional devices (in Legacy mode)= . This patch series add VIRTIO 1.0 support so that tests can run against Non-Transitional devices too. The virtio-fs device is Non-Transitional, so this is a prerequisite for virtio-fs qos tests.
