pc-bios/s390-ccw: Split virtio-scsi code from virtio_blk_setup_device()

2022-07-06T16:35:10+00:00

The next patch is going to add more virtio-block specific code to virtio_blk_setup_device(), and if the virtio-scsi code is also in there, this is more cumbersome. And the calling function virtio_setup() in main.c looks at the device type already anyway, so it's more logical to separate the virtio-scsi stuff into a new function in virtio-scsi.c instead.

pc-bios/s390-ccw: Do not bail out early if not finding a SCSI disk

2020-10-06T17:36:50+00:00

In case the user did not specify a boot device, we want to continue looking for other devices if there are no valid SCSI disks on a virtio- scsi controller. As a first step, do not panic in this case and let the control flow carry the error to the upper functions instead.

pc-bios/s390-ccw: Build a reasonable max_sectors limit

2017-05-19T10:29:01+00:00

Now that we've read all the possible limits that have been defined for a virtio-scsi controller and the disk we're booting from, it's possible that we are STILL going to exceed the limits of the host device. For example, a "-device scsi-generic" device does not support the Block Limits VPD page. So, let's fallback to something that seems to work for most boot configurations if larger values were specified (including if nothing was explicitly specified, and we took default values).
