8250 should have claimed ttyS3 in 2.6.21 and earlier. So from
the 8250 point of view, 2.6.21 and 2.6.23 should behave the same.

>From the smsc-ircc2 point of view, 2.6.21 and 2.6.23 should work
the same except for the additional quirk_smc_enable(). If
2.6.23 is worse than 2.6.21, please try removing the body of
quirk_smc_enable() and see whether that makes 2.6.23 as good
as 2.6.21.

For smsc-ircc2, 2.6.23 is definitely a regression from 2.6.22,
because 8250 stayed out of the way in 2.6.22. But we had to
revert 8250 back to the 2.6.21 behavior because the change
swapped ttyS0 and ttyS1 on some machines, so we just have to
live with that 8250/smsc-ircc2 conflict for the time being.

I only know that this worked in 2.6.21. I remind that previous regression was
post-2.6.21 which obviously implies that it did work ...

For reference I attach dmesg from 2.6.21. I do not see any ttyS3 there ...

This worked in 2.6.22 with the same quirks. I will test without later but I
fail to see how they are related.

This worked in 2.6.21 and 2.6.22 (and earlier BTW). So if you just had revert
to 2.6.21 it would have worked. Something else changed.

OK, let me know what happens. The way it's related is that the quirk
fiddles with the IRDA device, and it probably changes the SIR config
so that it starts responding at the ttyS3 address. In your 2.6.23
log, I see this:

[ 512.476243] pnp: Device 00:0a activated.
[ 512.476301] 00:0a: SMCf010 not responding at SIR 0x100, FIR 0x2e8; auto-configuring
[ 512.477861] pnp: Device 00:0a disabled.
[ 512.483492] pnp: Device 00:0a activated.
[ 512.483520] 00:0a: not responding at SIR 0x100, FIR 0x2e8; swapping SIR/FIR and reconfiguring
[ 512.485056] pnp: Device 00:0a disabled.
[ 512.491652] pnp: Device 00:0a activated.
[ 512.491679] 00:0a: responds at SIR 0x2e8, FIR 0x100

After the quirk, the FIR part is enabled at 0x100 and we assume (the
quirk doesn't actually check) the SIR part is enabled at 0x2e8. The
8250 driver will claim a SIR device at 0x2e8 as ttyS3.

Without the quirk, the SIR device seems to be either at 0x100 (where
the 8250 driver will not look) or is not enabled at all.

You are probably right. Disabling quirk makes it work again (with pnp off in
smsc-ircc2 of course).

Hmm ... is there any reason why this quirk is in PnP core in the first place?
Would not it be more logical to have it in (PnP) part of smsc-ircc2? This way
it could share code with legacy detection; and it even may have chance to
work - assuming BIOS is aware that 0x100 is claimed by PCMCIA it could
allocate different port when we try to activate device after that ... should
I give it a try?

I think pnp is off in smsc-ircc2 by default, right?

I agree it would make sense to put the quirk in smsc-ircc2, since
we only need it if we want to use the smsc-ircc2 driver. But I don't
think we have a mechanism for calling quirks at module load-time, so
it has to be part of the static kernel. And we don't have anything
like DECLARE_PCI_FIXUP_SECTION, so it really has to be in quirks.c for
now.

How does the following patch look?



PNP: remove SMCf010 quirk

If the quirk enables the SIR part of the SMCf010 device, the 8250 driver
may claim it as a legacy ttyS device, which makes the legacy probe in the
smsc-ircc2 driver fail.

I am fine with any patch that works. Of course, it would be better to fix 8250
to respect PnP (it does load 8250_pnp in the first place).

I agree. 8250_pnp is actually fine -- it won't claim SMCf010 devices.
The problem is that we have the legacy addresses (including the SMCf010
SIR range) in SERIAL_PORT_DFNS, so 8250.c claims the SIR range in
serial8250_isa_init_ports().

I'm still hoping to fix that bit of 8250, but it's going to take some
work.

I'll post the SMCf010 quirk removal as a fix for the 2.6.23-rc3
regression.
