[PATCH for-5.1 0/2] Unbreak make check SPEED=slow

[PATCH for-5.1 0/2] Unbreak make check SPEED=slow

[Markus Armbruster]

On the one hand, getting bitten by this bug in production seems
somewhat unlikely.  On the other hand, shipping with broken "make
check" would be embarrassing.  So let's consider the fix for 5.1.

Markus Armbruster (2):
  msf2: Unbreak device-list-properties for "msf-soc"
  hw: Mark nd_table[] misuse in realize methods FIXME

[PATCH for-5.1 1/2] msf2: Unbreak device-list-properties for "msf-soc"

[Markus Armbruster]

Watch this:

    $ qemu-system-aarch64 -M ast2600-evb -S -display none -qmp stdio
    {"QMP": {"version": {"qemu": {"micro": 50, "minor": 0, "major": 5}, "package": "v5.0.0-2464-g3a9163af4e"}, "capabilities": ["oob"]}}
    {"execute": "qmp_capabilities"}
    {"return": {}}
    {"execute": "device-list-properties", "arguments": {"typename": "msf2-soc"}}
    Unsupported NIC model: ftgmac100
    armbru@dusky:~/work/images$ echo $?
    1

This is what breaks "make check SPEED=slow".

Root cause is m2sxxx_soc_initfn()'s messing with nd_table[] via
qemu_check_nic_model().  That's wrong.

We fixed the exact same bug for device "allwinner-a10" in commit
8aabc5437b "hw/arm/allwinner-a10: Do not use nd_table in instance_init
function".  Fix this instance the same way: move the offending code to
m2sxxx_soc_realize(), where it's less wrong, and add a FIXME comment.

It's rather just a work-around that avoids the crash than a real fix. I
think we can use it for the upcoming 5.1 release, but it would be great
if you could rework this code for 5.2, so that the nd_table handling is
moved to msf2-som.c instead.

 Thanks,
  Thomas

Yes this is not a 'fix' but rather a kludge.

As long as nobody comes up with a proper clean up within the next days
that moves the nd_table[] access to msf2-som.c, I think this is an
acceptable work-around for 5.1.

[PATCH for-5.1 2/2] hw: Mark nd_table[] misuse in realize methods FIXME

[Markus Armbruster]

nd_table[] contains NIC configuration for boards to pick up.  Device
code has no business looking there.  Several devices do it anyway.
Two of them already have a suitable FIXME comment: "allwinner-a10" and
"msf2-soc".  Copy it to the others: "allwinner-h3", "xlnx-versal",
"xlnx,zynqmp", "sparc32-ledma", "riscv.sifive.u.soc".

Maybe we should add an entry to

I'd prefer to leave that to someone who knows how this should be done
properly, and thus has a better idea on how big the bite actually is.
Figuring this out myself might be more work than fixing it.
