nvidia0: [GIANT-LOCKED]


Situation:
0) I have 1GB of RAM
1) using or disabling nvidia.ko makes no difference
2) using 'osscore_load="yes"' and 'envy24_load="yes"' in '/boot/loader.conf' after copying all OSS-modules to '/boot/modules' produces a nice kernel panic during boot
3) using original FreeBSD-6.1-RELEASE or my own 6.2-kernel makes NO difference at all. I haven't tested 7.0-kernel 'cause I would like to keep my nvidia driver

Any ideas?

Cheers,
Uri

Hi,

Have you checked to see if OSS 3.99.4 works?. OSS 4.0rc2 hasn't been tested with all memory models but you can see /usr/lib/oss/build/osscore.c to see why the memory is being allocated beyond 256MB - this Envy24 can only access < 256MB .

Yeah, you're my man, Dev. That's the hint I was looking for. :D

I've got my Audiophile 2496 driver-loaded and working after creating a symbolic link '/dev/dsp -> /dev/dsp0'. 'though with 'poor' Latency of 24ms in artsd (in comparision to my VIA8233-onboard-sound with 5ms latency [kernel driver module used for that]).

Under OSS 3.99.4 the only thing that's working is artsd. Nor XMMS with disabled artsd. I even had to disable some channels in the AP2496-driver config in order to get rid of the "couldn't allocate xxxx bytes for DMA buffer"-messages. Latency was worse than now with OSS-4.00RC2.

1) Is there a way to use '/dev/dsp' with multiple applications simultanously?
2) MIDI-support for Audiophile 2496 in near availability?

Uri

Excellant!!! Thanks. We are working on fixing up the automatic opening of devices.
