The changes is to allow some limited mixer manipulation through
the audio device (instead of the mixer device).
This rendered 4 methods in audio_hw_if unused so garbage collect these.
- the console code from arm32/dev has been moved here as it is VIDC
specific.
- A few minoir code cleanups to help it fit with the restructures VIDC
sources
at the same time instead by using two different calls. This enables
it to check more easily if the combined mode is all right.
- Improve the error checking in audio.c.
- Add a new audio property, AUDIO_PROP_INDEPENDENT, show if the
play and record settings are independent.
- Fix some buglets in audio.c.
- Change the way attach and open works to allow multiple audio
devices.
- Split the mulaw.c file into two to avoid dragging in mulaw
convertsion when they are not needed. Add 16 bit alaw/mulaw tables.
- Change the way audio properties are gotten.
- Recognize more versions os SoundBlaster.
In the probe routines check the mainbus attach args mb_iobase field
to verify that the iobase did not default as an iobase address needs
to be specifically specified.
- It is now possible to handle devices that want "looping" DMA,
e.g. the SoundBlaster correctly. The WSS and SB drivers use this.
To do this several new methods were introduced in audio_hw_if.
- Different silence handling (forced by previous change).
- The audio driver can now be mmap()-ed, but due to problems in
the VM system only for writing for now.
- The OSS (Linux) audio emulation takes advantage of some of the
new features.
renamed AUDIO_ENCODING_SLINEAR and AUDIO_ENCODING_LINEAR reverts to the
NetBSD 1.2 sematics. A kernel with COMPAT_12 defined will accept
AUDIO_ENCODING_LINEAR and treat it as before, without COMPAT_12 it
will be rejected.
Set the encoding parameters slightly differently.
Remove the SW encoding/decodinf functions from this interface
and move them to the audio_parameter struct; this is both more efficient
and flexible.
as the only argument and cast this as appropriate now that the function
pointers to the interrupt registration functions are fully prototyped.
Use <machine/conf.h> for the declarations of the device driver entry
points.
motherboard.
Cleaned up a lot of code to match KNF.
When the device is attach the vidc refclk frequency is reported along
with the amount of video memory and the type.
go wrong when console blanking occurs while X is running.
The blanktime ioctl now allows blanking times to be set, force
immediate blanking or diable blanking on a per virtual console basis.
Updated the console version number to revision D.
