[PATCH v4 00/16] libqos: add VIRTIO PCI 1.0 support |

v4:
* Introduce bool d->features_negotiated so that tests can negotiate a
0 feature bit set in Legacy mode [Thomas]
* Make the FEATURES_OK code change in qvirtio_set_driver_ok() clearer and
mention it in the commit description [Thomas]
* Fix indentation in qvring_init() [Thomas]
v3:
* Now implements VIRTIO 1.0 fully (vring, device initialization).
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-compliant!)
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=ppc64-softmmu/qemu-system-ppc64 tests/qos-test &&
QTEST_QEMU_BINARY=x86_64-softmmu/qemu-system-x86_64 tests/qos-test'
QTEST_QEMU_BINARY=arm-softmmu/qemu-system-arm tests/qos-test'
v2:
* Fix checkpatch.pl issues, except MAINTAINERS file warning. libqos already
has maintainers and the new virtio-pci-modern.[ch] files don't need extra
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 adds 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.
Stefan Hajnoczi (16):
