Actually, the ALSA drivers with PnPBIOS support (snd-cs4232, snd-es18xx and
snd-opl3sa2) do not in fact loose any parameters and the few known trouble
spots there are using
modprobe snd-foo isapnp=0 port=...
as their workaround, bypassing all of PnP, and this still works completely
the same as before.
I do not expect any trouble. A few users might have _mistakingly_ added
parameters to an ISAPnP only (as in, not also PnPBIOS) driver due to
googling up your generic bad-advice webforum that said that worked for
someone with a heavy sounding nickname, but we can deal with that.
Moreover, as I've been experiencing on the ALSA list for a while now (where
I've been somewhat responsive to ISA related issues) basically anything but
PnPBIOS/ACPI ISA is mostly dead and as said, with an isapnp=0 in the drivers
there which known issues are using, there's no difference.
Advice is always good, but I'd not put in the ALSA documentation (wrong
place) and even in the changelog it sounds a bit overly alarming in my own
opinion. The expected fall-out is... <crickets>...
Hm, but still some notes are needed for ALSA-Configuration.txt
mentioning that the resource parameters like port, io, etc can be used
only when isapnp=no on some drivers. The parameters are still there,
so people may wonder if it has no use.
Okay, something like this? Incremental...
By the way, eventually I'd in fact probably like to move some of the drivers
that now still support legacy ISA over to PnP only. After all, chips such as
the CMI8330, CS4232+, ES1869+ and OPL3SA2 _are_ PnP only chips.
Certainly for CS4232+ and ES1869+ that can't be done currently as we know
people are in fact using isapnp=0 to work around PnPBIOS issues but from the
previous report there it seemed that might actually just consist of the BIOS
claiming no resource change is possible, which pnp_activate_dev (through
pnp_autoconfig_dev) insist on anyway. This would be something to fix inside
PnP instead...
Anyways, here's just a further Documentation update. You once told me to
start new threads for patches, but that seems clumsy now... :-|
