tests/libqos: Move the libqos files under tests/qtest/

2020-01-12T10:42:41+00:00

The qos stuff belongs to qtest, so move it into that directory, too. Message-Id: <20191218103059.11729-8-thuth@redhat.com> Reviewed-by: Paolo Bonzini Signed-off-by: Thomas Huth

libqos: add VIRTIO PCI 1.0 support

2019-10-25T11:46:22+00:00

Implement the VIRTIO 1.0 virtio-pci interface. The main change here is that the register layout is no longer a fixed layout in BAR 0. Instead we have to iterate of PCI Capabilities to find descriptions of where various registers are located. The vring registers are also more fine-grained, allowing for more flexible vring layouts, but we don't take advantage of that.

libqos: extract Legacy virtio-pci.c code

libqos: make the virtio-pci BAR index configurable

2019-10-25T11:46:22+00:00

The Legacy virtio-pci interface always uses BAR 0. VIRTIO 1.0 may need to use a different BAR index, so make it configurable.

libqos: expose common virtqueue setup/cleanup functions

2019-10-25T11:46:22+00:00

The VIRTIO 1.0 code will need to perform additional steps but it will reuse the common virtqueue setup/cleanup code. Make these functions public. Make sure to invoke callbacks via QVirtioBus instead of directly calling the virtio-pci Legacy versions of these functions.

libqos: add MSI-X callbacks to QVirtioPCIDevice

2019-10-25T11:46:22+00:00

The MSI-X vectors are programmed differently in the VIRTIO 1.0 and Legacy interfaces. Introduce callbacks so different implementations can be used depending on the interface version.

libqos: pass full QVirtQueue to set_queue_address()

Instead of just passing the vring page frame number, pass the full QVirtQueue. This will allow the VIRTIO 1.0 transport to program the fine-grained vring address registers in the future.

libqos: access VIRTIO 1.0 vring in little-endian

2019-10-25T11:46:22+00:00

VIRTIO 1.0 uses little-endian for the vring. Legacy VIRTIO uses guest endianness. Adjust the code to handle both. Note that qvirtio_readq() is not defined because it has no users. All the other accessors are really needed. Signed-off-by: Stefan Hajnoczi Reviewed-by: Thomas Huth Message-Id: <20191023100425.12168-10-stefanha@redhat.com> Reviewed-by: Michael S.
