Re: PCI128 and RELENG_4

2001-01-21 Thread Ben Jackson

Hm, I have:

pcm0:  port 0xd000-0xd03f irq 9 at device 10.0 on pci0

FreeBSD Audio Driver (newpcm) Dec 26 2000 20:17:05
Installed devices:
pcm0:  at io 0xd000 irq 9 (1p/1r channels duplex)

I just tried recording and I can't get anything out of line0 or mic.
Also, the sox port is broken...  rec doesn't do anything.  I also tried
record from an OSS dist.

I'm assuming:

>   % mixer
>   Mixer mic  is currently set to   0:0

You are adjusting that if you're using the mic input.

I'm also curious to know if you get a hiss from the speakers all the time
that goes away if you set the synth volume to 0.  That's what happens
with my SB PCI128.

Re: SIGSEGV can be blocked!?

The instruction that caused the SEGV is going to restart after any handler
runs because the handler may have mapped the page that caused the fault.

On other operating systems you can block SEGV for purposes of asynchronous
signals (ie `kill -SEGV') but not for synchronous signals.  To quote from
the Solaris sigprocmask manpage:

 Signals that  are  generated  synchronously  should  not  be
 masked.  If  such  a  signal  is  blocked and delivered, the
 receiving process is killed.

and indeed a test program shows that you still get SEGV in that case.
You can still shoot yourself in the foot with a SEGV handler that doesn't
eliminate the fault.

So a user can *install* and not have to worry about setting up devices.
You don't need a soundcard to do an install.  Once you've done the
installation you can build a kernel which supports your soundcard.

If it's causing problems on installs maybe it should be disabled by
default, even if it is built into the kernel.

> You guys are not overclocking are you ??

No!  Just because I have a BP6 doesn't mean I'm overclocking it.  The HPT
controller has always done this.  Would more messages help, eg bootverbose?
I tried DDB on 4.0 and ctrl-esc didn't get out of this state.
