Long lines are harder to read and harder to diff; in fact, if lines get too long (> 1000 bytes), it starts causing issues where git send-email refuses to send patches for the file. I've cleaned up the tests directory in the past (see commits bd6c46fa, 3b750d13), but new long lines have been introduced in the meantime. Why 90 instead of 80? Because there were too many tests on the fringe edge, and I didn't want to edit that many files. Add a syntax check to prevent future long lines. * cfg.mk (sc_prohibit_long_lines): New rule. * tests/qemuxml2argvdata/qemuxml2argv-*.args: Split lines of any file with content longer than 90 columns. * tests/storagevolxml2argvdata/*.argv: Likewise.

Except the scsi host device's controller is "lsilogic", mapping between the libvirt attributes and scsi-generic properties is: libvirt qemu ----------------------------------------- controller bus ($libvirt_controller.0) bus channel target scsi-id unit lun For scsi host device with "lsilogic" controller, the mapping is: ('target (libvirt)' must be 0, as it's not used; 'unit (libvirt) must <= 7). libvirt qemu ---------------------------------------------------------- controller && bus bus ($libvirt_controller.$libvirt_bus) unit scsi-id It's not good to hardcode/hard-check limits of these attributes, and even worse, these limits are not documented, one has to find out by either testing or reading the qemu code, I'm looking forward to qemu expose limits like these one day). For example, exposing "max_target", "max_lun" for megasas: static const struct SCSIBusInfo megasas_scsi_info = { .tcq = true, .max_target = MFI_MAX_LD, .max_lun = 255, .transfer_data = megasas_xfer_complete, .get_sg_list = megasas_get_sg_list, .complete = megasas_command_complete, .cancel = megasas_command_cancel, }; Example of the qemu command line (lsilogic controller): -drive file=/dev/sg2,if=none,id=drive-hostdev-scsi_host7-0-0-0 \ -device scsi-generic,bus=scsi0.0,scsi-id=8,\ drive=drive-hostdev-scsi_host7-0-0-0,id=hostdev-scsi_host7-0-0-0 Example of the qemu command line (virtio-scsi controller): -drive file=/dev/sg2,if=none,id=drive-hostdev-scsi_host7-0-0-0 \ -device scsi-generic,bus=scsi0.0,channel=0,scsi-id=128,lun=128,\ drive=drive-hostdev-scsi_host7-0-0-0,id=hostdev-scsi_host7-0-0-0 Signed-off-by: NHan Cheng <hanc.fnst@cn.fujitsu.com> Signed-off-by: NOsier Yang <jyang@redhat.com>
