Commit Message

Mario Limonciello June 1, 2022, 5:21 p.m. UTC 
commit 4fb0abfee424 ("x86/amd_nb: Add AMD Family 19h Models (10h-1Fh)
and (A0h-AFh) PCI IDs") had claimed to add the IDs for models A0h-AFh,
but it appears to only have added the models 10h-1Fh.

Add the actual IDs for A0-AF which are needed for SMN communication to
work properly in amd_nb.

This file is nominally sorted by numeric device ID inside the vendor
section, but that has really deteriorated over time.

I can't quite figure out the rationale for deciding whether to put
things in amd_nb.c vs pci_ids.h.  The IDs in amd_nb.c look basically
the same as this one.

Normally we put things in pci_ids.h if they are used more than one
place.  PCI_DEVICE_ID_AMD_19H_MA0H_DF_F3 looks like it's only used in
one place.

It seemed like it was more oriented to be sorted by the macro definition 
than the ID.

I suppose you weren't on CC for patch 2/2 in this series (thanks 
scripts/get_maintainer.pl), so it's not obvious to you that this ID is 
used in a second place in patch 2.  I didn't want to ping pong in/out 
from amd_nb.c in the series.

Here is a lore link to it:

Yeah, it's kind of a mess.  Not really clear which way.

I'll need an Ack from a x86 maintainer to apply this series,
or it needs to be applied through x86. I sent an Ack for patch 2/2,
so the latter would be fine with me.

Thanks,
