[Qemu-devel] [PATCH v2 0/5] vhost-scsi: support to assign boot order

[arei.gonglei]

From: Gonglei <address@hidden>

Qemu haven't provide a bootindex property for vhost-scsi device.
So, we can not assign the boot order for it at present. But
Some clients/users have requirements for that in some scenarios.
This patch achieve the aim in Qemu side.

Because Qemu only accept an wwpn argument for vhost-scsi, we
cannot assign a tpgt. That's say tpg is transparent for Qemu, Qemu
doesn't know which tpg can boot, but vhost-scsi driver module
doesn't know too for one assigned wwpn.
    
At present, we assume that the first tpg can boot only, and add
a boot_tpgt property that defaults to 0. Of course, people can
pass a valid value by qemu command line.

v2 -> v1: (Thanks to Paolo's suggestion)
 - change calling  qdev_get_own_fw_dev_path_from_handler in
   get_boot_devices_list, and convert non-NULL suffixes to
   implementations of FWPathProvider in Patch 1. (Paolo)
 - add a boot_tpgt property for vhost-scsi in Patch 4. (Paolo)
 - remove the ioctl calling in Patch 4, because the kernel
   patch hasn't been accepted.
