[PATCH v4 00/47] Rework matching of network devices to -nic options

[PATCH v4 00/47] Rework matching of network devices to -nic options

[David Woodhouse]

Most platforms iterating directly over the nd_table[] are doing one of 
two things. Either they are creating the NIC for their platform and want
to find a matching -nic configuration for it, if such exists. Or they
are only going to create that platform NIC if a matching config *does*
exist.

All of those can be converted to the new qemu_configure_nic_device()
and qemu_create_nic_device() functions. The latter of which will call
qdev_new() to create the device (and apply the config) if a matching
NIC config does exist for it. The existing behaviour of each platform
has been preserved for now, despite it being apparently fairly random.

PCI and indeed XenBus can use a qemu_create_nic_bus_devices() which will 
create all NICs that live on a given bus type. That covers most 
platforms, but some PCI platforms do something special with the first 
NIC of a given type, placing it in the slot where it would have been on 
the real hardware. There were various inconsistencies in the way the 
platforms did so, and whether they cared what model the NIC was. Those 
subtle behavioural changes I *have* allowed to change, and now the 
pci_init_nic_slot() function will pick the first NIC that the user 
specified which isn't explicitly *not* the default type, and put that
in the specified slot.

The tests for npcm7xx used to lament that they had to instantiate both
NICs even when they wanted to test only the second, because there was
no way to specify which hardware devices gets which configuration. I
made that untrue, by allowing 'emc0' and 'emc1' aliases, and fixed up
the test accordingly.

There are one or two special cases which want to do special things with
the MAC address of the primary NIC, to set up a system identification
(or force it to use an Apple OUI, in the case of m68k/q400). All those
work out relatively cleanly too.

And I can clean up the ugly patch which fixed up the Xen network device 
handling, and replace it with a simple call to the new 
qemu_create_nic_bus_devices() function.

I suspect that we can remove the pci_init_nic_devices() from platform
code and just do it later, except for platforms which *care* which
PCI bus the dynamic devices go on (is that just sun4u which puts its
primary NIC onto a different bus?).

Finally, while we're at it, clean up -nic model=help to only print
the device models which are actually usable on the given platform
rather than just listing them *all*.

And now we can make nd_table[] and nb_nics static in net/net.c because
nothing else has any business poking at them directly.

 v4: Fix LASI_82596 build and rework HPPA machine support for it.
     Slight improvement to ISA NE2000 error handling in hw/i386/pc.c.
     Document new functions better in include/net/net.h.
          
 v3: Rebase to 8.2

 v2: Some build fixes after better coverage testing, revert the Xen fix
     in this series because I'm putting the less invasive hack into 8.2
     (hopefully).

[PATCH v4 01/47] net: add qemu_{configure, create}_nic_device(), qemu_find_nic_info()

[David Woodhouse]

From: David Woodhouse <dwmw@amazon.co.uk>

Most code which directly accesses nd_table[] and nb_nics uses them for
one of two things. Either "I have created a NIC device and I'd like a
configuration for it", or "I will create a NIC device *if* there is a
configuration for it".  With some variants on the theme around whether
they actually *check* if the model specified in the configuration is
the right one.

Provide functions which perform both of those, allowing platforms to
be a little more consistent and as a step towards making nd_table[]
and nb_nics private to the net code.

One might argue that platforms ought to be consistent about whether
they create the unconfigured devices or not, but making significant
user-visible changes is explicitly *not* the intent right now.

The new functions leave the 'model' field of the NICInfo as NULL after
using it for the default NIC model, unlike the qemu_check_nic_model()
function which does set nd->model to match default_model explicitly.
This is acceptable because there is no code which consumes nd->model
except this NIC-matching code in net/net.c, and no reasonable excuse
for any code wanting to use nd->model in future.

Also export the qemu_find_nic_info() helper, as some platforms have
special cases they need to handle.

[PATCH v4 02/47] net: report list of available models according to platform

[David Woodhouse]

From: David Woodhouse <dwmw@amazon.co.uk>

By noting the models for which a configuration was requested, we can give
the user an accurate list of which NIC models were actually available on
the platform/configuration that was otherwise chosen.

[PATCH v4 03/47] net: add qemu_create_nic_bus_devices()

[David Woodhouse]

From: David Woodhouse <dwmw@amazon.co.uk>

This will instantiate any NICs which live on a given bus type. Each bus
is allowed *one* substitution (for PCI it's virtio → virtio-net-pci, for
Xen it's xen → xen-net-device; no point in overengineering it unless we
actually want more).

[PATCH v4 04/47] hw/pci: add pci_init_nic_devices(), pci_init_nic_in_slot()

[David Woodhouse]

From: David Woodhouse <dwmw@amazon.co.uk>

The loop over nd_table[] to add PCI NICs is repeated in quite a few
places. Add a helper function to do it.

Some platforms also try to instantiate a specific model in a specific
slot, to match the real hardware. Add pci_init_nic_in_slot() for that
purpose.

[PATCH v4 06/47] hw/xen: use qemu_create_nic_bus_devices() to instantiate Xen NICs

[David Woodhouse]

From: David Woodhouse <dwmw@amazon.co.uk>

When instantiating XenBus itself, for each NIC which is configured with
either the model unspecified, or set to to "xen" or "xen-net-device",
create a corresponding xen-net-device for it.

Now we can revert the previous more hackish version which relied on the
platform code explicitly registering the NICs on its own XenBus, having
returned the BusState* from xen_bus_init() itself.

This also fixes the setup for Xen PV guests, which was previously broken
in various ways and never actually managed to peer with the netdev.

[PATCH v4 12/47] hw/mips/fuloong2e: use pci_init_nic_devices()

[David Woodhouse]

From: David Woodhouse <dwmw@amazon.co.uk>

The previous behaviour was: *if* the first NIC specified on the command
line was an RTL8139 (or unspecified model) then it gets assigned to PCI
slot 7, which is where the Fuloong board had an RTL8139. All other
devices (including the first, if it was specified as anything other than
an rtl8319) get dynamically assigned on the bus.

The new behaviour is subtly different: If the first NIC was given a
specific model *other* than rtl8139, and a subsequent NIC was not,
then the rtl8139 (or unspecified) NIC will go to slot 7 and the rest
will be dynamically assigned.

[David Woodhouse]

From: David Woodhouse <dwmw@amazon.co.uk>

The Malta board setup code would previously place the first NIC into PCI
slot 11 if was a PCNet card, and the rest (including the first if it was
anything other than a PCNet card) would be dynamically assigned.

Now it will place any PCNet NIC into slot 11, and then anything else will
be dynamically assigned.

[PATCH v4 15/47] hw/ppc/prep: use pci_init_nic_devices()

[David Woodhouse]

From: David Woodhouse <dwmw@amazon.co.uk>

Previously, the first PCI NIC would be placed in PCI slot 3 and the rest
would be dynamically assigned. Even if the user overrode the default NIC
type and made it something other than PCNet.

Now, the first PCNet NIC (that is, anything not explicitly specified
to be anything different) will go to slot 3 even if it isn't the first
NIC specified on the command line. And anything else will be dynamically
assigned.

[PATCH v4 16/47] hw/ppc/spapr: use qemu_get_nic_info() and pci_init_nic_devices()

[David Woodhouse]

From: David Woodhouse <dwmw@amazon.co.uk>

Avoid directly referencing nd_table[] by first instantiating any
spapr-vlan devices using a qemu_get_nic_info() loop, then calling
pci_init_nic_devices() to do the rest.

No functional change intended.

[PATCH v4 18/47] hw/sh4/r2d: use pci_init_nic_devices()

[David Woodhouse]

From: David Woodhouse <dwmw@amazon.co.uk>

Previously, the first PCI NIC would be assigned to slot 2 even if the
user override the model and made it something other than an rtl8139
which is the default. Everything else would be dynamically assigned.

Now, the first rtl8139 gets slot 2 and everything else is dynamic.

[PATCH v4 19/47] hw/sparc64/sun4u: use pci_init_nic_devices()

[David Woodhouse]

From: David Woodhouse <dwmw@amazon.co.uk>

The first sunhme NIC gets placed a function 1 on slot 1 of PCI bus A,
and the rest are dynamically assigned on PCI bus B.

Previously, any PCI NIC would get the special treatment purely by
virtue of being first in the list.

[PATCH v4 25/47] hw/net/smc91c111: use qemu_configure_nic_device()

[David Woodhouse]

From: David Woodhouse <dwmw@amazon.co.uk>

Some callers instantiate the device unconditionally, others will do so only
if there is a NICInfo to go with it. This appears to be fairly random, but
preserve the existing behaviour of each caller for now.

I like the idea to use the alias to configure a certain on-board NIC :-)

[PATCH v4 29/47] hw/arm/stellaris: use qemu_find_nic_info()

[David Woodhouse]

From: David Woodhouse <dwmw@amazon.co.uk>

Rather than just using qemu_configure_nic_device(), populate the MAC
address in the system-registers device by peeking at the NICInfo before
it's assigned to the device.

Generate the MAC address early, if there is no matching -nic option.
Otherwise the MAC address wouldn't be generated until net_client_init1()
runs.

Out of scope of your patch, but I wonder why we didn't use 
qdev_prop_set_macaddr() with an according MAC address property for this 
device...?

Yeah. I suppose it could have done. But strictly speaking, it *isn't* a
MAC address on the underlying PROM device; it's just two 32-bit
registers. Which each happen to contain 24 bits of the MAC address.

Partly because this code originates from 2007 and
qdev_prop_set_macaddr() only arrived in 2009. When I did
a basic qdev conversion in 2021 (commit 4bebb9ad4e4) I
just did a simple change from "directly set fields in the
device state struct" to "set fields in the device state
struct via some qdev properties".

But also because the device we're setting these fields on isn't
an ethernet device -- it's a "system control" device with a bunch
of registers, including two which have no effect on the hardware
behaviour but which by convention usually have the MAC address in
them. So as an interface to the system control device it does make
some sense to have it be "what are the values of these two 'user'
registers" ?

(qdev_prop_set_macaddr() and the associated mac address property
seem a bit odd -- qdev_prop_set_macaddr() is called from exactly
one place, and it takes an array of bytes, marshalls them into
an ASCII string representation, sets the property, and then the
property setter parses them back out of ASCII and into an array
of bytes again...)

[PATCH v4 33/47] hw/m68k/q800: use qemu_find_nic_info()

[David Woodhouse]

From: David Woodhouse <dwmw@amazon.co.uk>

If a corresponding NIC configuration was found, it will have a MAC address
already assigned, so use that. Else, generate and assign a default one.

Using qemu_find_nic_info() is simpler than the alternative of using
qemu_configure_nic_device() and then having to fetch the "mac" property
as a string and convert it.

Don't we have to change nd->macaddr.a[0 to 2] with this hard-coded 
MAC-prefix, too?

I don't think so.

We either get the MAC address from 'nd' if that exists, or generate a
new MAC address with qemu_macaddr_default_if_unset().

Then we override the OUI in the actual device. We don't care about 'nd'
any more at that point.

Thank you, just just about completes my set. Every patch now has a
Reviewed-by: except two of them (hw/s390x/s390-virtio-ccw and
hw/arm/aspeed) which only have an Acked-by: 

I think according to The Rules I just need a maintainer to *tell* me to
send a pull request and then I'm allowed to do so?

Yeah, go ahead and send a pullreq for this.

(I have a new board model brewing so it would be handy for me
to have the new functions upstream so I can create the ethernet
device in the right way :-))

The MIPS SIM platform instantiates its NIC only if a corresponding

[PATCH v4 37/47] hw/net/lasi_i82596: Re-enable build

[David Woodhouse]

From: David Woodhouse <dwmw@amazon.co.uk>

When converting to the shiny build-system-du-jour, a typo prevented the
last_i82596 driver from being built. Correct the config option name to
re-enable the build. And include "sysemu/sysemu.h" so it actually builds.

[PATCH v4 38/47] hw/net/lasi_i82596: use qemu_create_nic_device()

[David Woodhouse]

From: David Woodhouse <dwmw@amazon.co.uk>

Create the device only if there is a corresponding NIC config for it.
Remove the explicit check on nd_table[0].used from hw/hppa/machine.c
which (since commit d8a3220005d7) tries to do the same thing.

The lasi_82596 support has been disabled since it was first introduced,
since enable_lasi_lan() has always been zero. This allows the user to
enable it by explicitly requesting a NIC model 'lasi_82596' or just
using the alias 'lasi'. Otherwise, it defaults to a PCI NIC as before.

v4.1: Only attempt to find GPIOs on the lasi_dev if it exists. This
      was theoretically broken already, but enable_lasi_dev() is
      hard-coded to zero, so adding the user override to enable it
      is what actually exposed the bug.

(Not reposting the whole series for that)

[PATCH v4 44/47] net: remove qemu_check_nic_model()

[David Woodhouse]

From: David Woodhouse <dwmw@amazon.co.uk>

There are no callers of this function any more, as they have all been
converted to qemu_{create,configure}_nic_device().

[PATCH v4 46/47] net: remove qemu_show_nic_models(), qemu_find_nic_model()

[David Woodhouse]

From: David Woodhouse <dwmw@amazon.co.uk>

These old functions can be removed now too. Let net_param_nic() print
the full set of network devices directly, and also make it note that a
list more specific to this platform/config will be available by using
'-nic model=help' instead.
