From: Jared Rossi <[email protected]>
This patch series introduces an IPLB subtype to support PCI devices, which may
be built if a device has been assigned a boot index and is identified as a PCI
device with a corresponding s390 PCI Bus device.
Boot support is only added for virtio-blk-pci at this time and is limited to
devices with an assigned bootindex.
A "loadparm" property is added to virtio-blk-pci boot devices on s390x.
A simple test to check basic functionality is added to the cdrom-tests in qtest.
Changes v2 -> v3:
- Negotiate VIRTIO_F_VERSION_1 and support PCI native little endian
- Split patches further to isolate clean-up and substantive changes
- Move byteswap helpers from pci.c to virtio-pci.c to avoid passing the file
handle throughout
- Convert IPL type to enum and add defaults for switch cases
- Add PCI loadparm only to virtio-blk devices
- Do not assume PCI devices are virtio when building IPLB
