Description Gerald Teschl 2001-07-25 11:48:06 EDT

The opl3sa2 driver has an isapnp option but if inserted with isapnp=1 it
fails to
activate the card and subsequently does not find it. If I activate the card
by writing
to /proc/isapnp

cat > /proc/isapnp <<EOF
card 0 YMH0800
dev 0 YMH0021
port 0 0x220
port 1 0x530
port 2 0x388
port 3 0x330
port 4 0x370
irq 0 5
dma 0 0
dma 1 1
activate
dev 0 YMH0022
port 0 0x201
activate
EOF


and then insert the module with isapnp=1 it works fine.

This defect is considered SHOULD-FIX for the Fairfax release.

Comment 3 Arjan van de Ven 2001-08-17 08:20:07 EDT

How is the card identified BEFORE you set values into it ?

Comment 4 Gerald Teschl 2001-08-21 09:20:03 EDT

You mean the content of /proc/isapnp ?

Comment 6 Gerald Teschl 2002-05-24 07:32:53 EDT

Still broken in 7.3.

Comment 7 Gerald Teschl 2002-06-03 08:13:57 EDT

I debugged this problem: The cause is that the card requires dma=0 to work but
isapnp.c excludes "0" for dma values. I have sent a proposed patch to the
kernel mailing list.

patch to opl3sa2.c

Comment 9 Gerald Teschl 2002-06-04 12:04:00 EDT

This is the patch which fixes the problem (it has been discussed on
the kernel/sound mailing list).

Comment 10 Arjan van de Ven 2002-06-05 07:33:04 EDT

Added for the next errata build

Comment 11 Gerald Teschl 2002-06-07 04:04:44 EDT

I had some further discussions with the maintainer of the opl3sa2 driver
and we decided that a better fix is to add this as a quirk to the isapnp
driver. I'll attach the two necessary patches. Sorry...
