augustss 658656bb99 Audio changes: 
- 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.

augustss a63034762b Audio: Remove the machine dependant code I put in audio.c by mistake. 
This adds another method to audio_hw_if.  Also remove a field from
audio_hw_if that was not read-only.

augustss d58bc6796f audio: Simplify handling of AUDIO_SETFD and committing of encoding mode. 1997-07-27 23:51:48 +00:00
augustss 9745684ebe Changes to the sudio system: 
- 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.

thorpej 7c03f46228 Don't print a warning if the returned transfer count is less than 0. 
This can happen during perfectly normal operation if:
	(a) We are using DMA to select a target, and
	(b) we are interrupted by another target reselecting us.
Per discussion with Paul Krannenburg.

pk fb5c729d4a Use `rr_iospace' to track the MMU page type bits. On sun4c/sun4m the 
iospace value is always learned from the PROM; on sun4, we infer it
from the BUS_* parameters.

This obsoletes the `bustype' argument in bus_tmp().

augustss e63a553175 Change the interface between high and lowlevel audio drivers again: 
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.
 1997-05-09 22:16:27 +00:00
augustss c4a52794f1 Convert to new orthogonal audio encoding scheme and implement 
some of the new encodings.  The change to ioctl AUDIO_GETENC is
NOT backwards compatible.

pk a05df4e228 * finish off support for the 82077 chip as found on sun4m machines. 
* add non-dma mode bit to `specify command', so formatting disks starts
  working (thanks to Jeremy Cooper for finding out about this).

augustss 526ef2f618 Change the interface between the high and low level audio drivers 
so that all audio encoding parameters are set at once.  This simplifies
the interface and make error checking easier.

pk 547d95a029 Remove esp FLUSH when residual bytes are present in FIFO, the ncr53c9x 
driver will flush when necessary. Doing the FLUSH here interferes
with DMA-enabled target selection.

pk 2357b53997 Avoid race for the chip's interrupt pending status bits in zscnputc()

mrg bb07095632 as per discussion with torek, allow TC=1. also add option 
to allow TC=0.  the zilog documentation says not to allow
TC=0 -- however, i tested this and it "does work", as far
as i could tell, so, allow this use if so desired.

pk 27b2f0ec7c Fix a `new-ARP' pasto. 1997-03-15 22:13:55 +00:00
is 07b064e02e New ARP system, supports IPv4 over any hardware link. 
Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.

For the detailed change history, look at the commit log entries for
the is-newarp branch.

cjs ca5f101ba7 Remove code that stops transfers of >63K. The Sun 4 doesn't have this 
limitation, and minphys() is supposed to catch this on other architectures.

required.
