The code is working here. I have a few questions:
- I'm working on -stable, so someone else should take care of -current... [well
this isn't really a question :-)]
- I would like to MFC some code (mainly isa.c 1.103 -> 1.104), but I understand
that I should avoid mixing the diffs togheter. What do you suggest? Should I
reply to my own PR (i386/6792) with just the Compatible Device ID patch and
open a new PR to backport that isa.c change? The problem is that I need to
change both isa.c and pnp.c at the same time to let that MFC work, so at the
end of the game I need to change pnp.c twice.
- I used the same array for both Vendor IDs and Compatible Device IDs, like in:
static struct edpnp_ids {
u_long vend_id;
char *id_str;
} edpnp_ids[] = {
{ 0x1980635e, "WSC8019"},
{ 0xd680d041, "NE2000 Compatible"},
{ 0 }
};
and it works:
[...]
Probing for PnP devices:
CSN 1 Vendor ID: WSC9008 [0x0890635e] Serial 0xdea47218 Comp ID: PNP80d6 [0xd680
d041]
ed1: address 00:20:18:72:a4:de, type NE2000 (16 bit)
ed1 (edpnp <NE2000 Compatible> sn 0xdea47218) at 0x280 irq 12 drq -1 flags 0x0 i
d 14
Probing for devices on the ISA bus:
[...]
Should I fix/remove bogus/useless Vendor IDs from if_ed.c and sio.c?
- I still would like to remove that structure definition (edpnp_ids) from sio.c
and if_ed.c to put it into pnp.h
- talking about sio.c, I don't have anymore the SupraExpress internal modem, so
I don't know what its Compatible Device ID looks like. There are a lot of
possible definitions in devids.txt (see PNP0500 -> PNP0502, plus PNPCxxx ->
PNPDxxx). I would be glad to everyone that sends to me its pnpinfo output...
