[Qemu-devel] [PULL 00/34] allow changing bootorder via monitor

[Gerd Hoffmann]

  Hi,

It's finally sorted, here comes the pull request for the bootindex patch
series which turns bootindex into a writable qom property and thereby
allows changing the bootorder at runtime via monitor.

please pull,
  Gerd

[Qemu-devel] [PULL 04/34] fw_cfg: add fw_cfg_machine_reset function

[Gerd Hoffmann]

From: Gonglei <arei.gonglei@huawei.com>

We must assure that the changed bootindex can take effect
when guest is rebooted. So we introduce fw_cfg_machine_reset(),
which change the fw_cfg file's bootindex data using the new
global fw_boot_order list.

Since the "bootindex" property is a QOM property and not a qdev property
now, we must alias it explicitly for virtio-blk-pci, as well as CCW and
s390-virtio.

[Qemu-devel] [PULL 29/34] usb-storage: add bootindex to qom property

[Gerd Hoffmann]

From: Gonglei <arei.gonglei@huawei.com>

Add a qom property with the same name 'bootindex',
when we remove it form qdev property, things will
continue to work just fine, and we can use qom features
which are not supported by qdev property.

Because usb-storage rely on scsi-disk which is created
in usb_msg_realize_storage(), so we should store the SCSIDevice
pointer in MSDState struct. Only in this way, we can change
the global boot_order_list when we want to change the bootindex
during vm rebooting by calling object_property_set_int(Object(SCSIDevice),).

[Gerd Hoffmann]

From: Gonglei <arei.gonglei@huawei.com>

At present, nvma cannot boot. However, it provides already
a bootindex property, so change bootindex to qom for nvma
device, but not call add_boot_device_path.

[Qemu-devel] [PULL 31/34] ide: add calling add_boot_device_patch in bootindex setter function

[Gerd Hoffmann]

From: Gonglei <arei.gonglei@huawei.com>

On this way, we can assure the new bootindex take effect
during vm rebooting. Meanwhile set the initial value of
bootindex to -1.

Because ide devcies's unit property maybe
do not initialize when set_bootindex function is called,
so that we don't know its suffix. So we have to save the
call add_boot_device_path() on ide realize/init function.
When we want to change bootindex during vm rebooting, we
can call it in setter function.

I've just noticed that this won't build with our minimum
required glib version: g_strcmp0 wasn't introduced
until glib 2.16.

It should be fairly easy to provide a back-compat implementation
in our glib-compat.h header, or you could just rephrase this
to work with the usual strcmp, since you're already doing a
manual NULL check on one of the arguments.

thanks

OK, thanks for your point, Peter.
I'll post a patch to fix this problem :)
