I've just found that another pcm device driver is in
/sys/i386/isa/sound/pcm86.c which is for FreeBSD(98).
Does it cause any problems for FreeBSD(98)?
# FreeBSD(98) is for NEC PC-98 architecture based PCs.
IIRC, config command of FreeBSD(98) has different behavior from
original one, and architecture depending codes were separated into
/sys/i386 and /sys/pc98. However, I'm not sure whether config of 98
version can handle it well if the pcm device is specified in kernel
configuration file.
Please look at this;
/sys/pc98/conf/files.pc98 ----
pc98/pc98/sio.c optional sio device-driver
i386/isa/snd/sound.c optional pcm device-driver
i386/isa/snd/dmabuf.c optional pcm device-driver
i386/isa/snd/ad1848.c optional pcm device-driver
i386/isa/snd/sb_dsp.c optional pcm device-driver
i386/isa/snd/clones.c optional pcm device-driver
i386/isa/sound/pcm86.c optional pcm device-driver
i386/isa/sound/dev_table.c optional snd device-driver
/sys/pc98/conf/GENERIC98----
#device pcm0 at isa? port 0xa460 irq 12 vector pcmintr
/sys/i386/conf/LINT----
# Luigi's snd code
# device pcm0 at isa? port ? tty irq 10 drq 1 flags 0x0 vector pcmintr
I suggest that we had better change the name for new pcm driver which
developed by Luigi (thanks a lot!), because;
- The name "pcm" has been already in used for FreeBSD(98) for long time.
- Luckily new pcm driver has just integrated in -current, not in any RELEASEes.
# I think alot of FreeBSD(98) users can be confused :-(
PS.
Sorry, I'm not a FreeBSD(98) user, so cannot test it.
