been done in a cleaner way by cleaning up the com.c #ifdefs some.
Software tty interrupts should be implemented on NetBSD/arm32,
but these hacks are no longer necessary to work around the lack.
- Implement pioc device driver that handles the memory mapped serial,
parallel, floppy and IDE interfaces.
- Provide child attachments to the generic drivers for serial,
parallel and IDE.
- These files are not generic or even really mainbus specific.
They are IOMD specific device.
- These devices have been re-written as child devices of the IOMD
device and the new versions will take up residence in the arm32/iomd
directory with the other IOMD specific code.
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.
the locators.
In wdcprobe_internal() set the WDCF_32BIT flag if the data32 io handle
is set.
All transfers to and from the data register now check for softc flags
to see if 32 bit transfers are enabled i.e. reading drive parameters
and doing a dump will use 32 bit transfers as well.
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.
