[Qemu-devel] [PATCH 1/6] Fix pci_vga_init() not to ignore bus argument

[Markus Armbruster]

Commit a414c306 converted all VGA devices to qdev.  It used
pci_create_simple() for all devices, except for this one it used
pci_create().  That's wrong, because it uses PCI bus#0 regardless of
the bus argument.  Fix by switching to pci_create_noinit().

[Qemu-devel] [PATCH 2/6] Fix pci_add storage not to exit on bad first argument

[Markus Armbruster]

Monitor command "pci_add ADDR storage ..." does its work in
qemu_pci_hot_add_nic().  It called pci_create(..., ADDR) to create the
device.  That's wrong, because pci_create() terminates the program
when ADDR is invalid.

Use pci_get_bus_devfn() and pci_create_noinit() instead.

[Qemu-devel] [PATCH 3/6] Make it obvious that pci_nic_init() can't fail

[Markus Armbruster]

Before this patch, pci_nic_init() returns NULL when it can't find the
model in pci_nic_models[].  Except this can't happen, because
qemu_check_nic_model_list() just searched for model in
pci_nic_models[], and terminated the program on failure.

Repeating the search here is pointless.  Instead, change
qemu_check_nic_model_list() to return the model's array index.

[Qemu-devel] [PATCH 4/6] Fix pci_add nic not to exit on bad model

[Markus Armbruster]

Monitor command "pci_add ADDR nic model=MODEL" uses pci_nic_init() to
create the NIC.  When MODEL is unknown or "?", this prints to stderr
and terminates the program.

Change pci_nic_init() not to treat "?" specially, and to return NULL
on failure.  Switch uses during startup to new convenience wrapper
pci_nic_init_nofail(), which behaves just like pci_nic_init() used to
do.

Bonus bug fix: we now check for qdev_init() failing there.

It's qdev_create() specialized for PCI, so name it accordingly.

 The Right Thing :) and it (obviously) fixes the problem with
pci_add for me.

 The only nitpick is that by passing an invalid NIC on command
line would make qemu dump valid NIC models.. But not an issue,
anyway.

Oh, and IMHO, at least patches 3 and 4 makes sense for stable-0.11;
patch 4 just needs an update for e1000 being the default model now

Patch 2 might make sense too with a little massaging

Mark.

Yes.  The others are mere cleanup, doubt they're appropriate for stable.
