This allows us to convert aucom to just another com attachment, and cleanup
some code in the com_arbus.c.
Additionally, we use a common com_cleanup routine rather than having a
zillion copies of it in the attachment points.
This has been tested on a number architectures, and it has been shown to get
close to comparable performance when COM_REGMAP is defined, and comparable
when it is not defined.

function may both read and write it's argument. Here it is only
reading from the data argument under WSMOUSEIO_SCALIBCOORDS, so it
is actually fine, but type protection can't express this.
audio framework
Summary of changes:
* struct audio_params
- remove sw_code, factor, factor_denom, hw_sample_rate,
hw_encoding ,hw_precision, and hw_channels. Conversion information
is conveyed by stream_filter_list_t.
- change the type of sample_rate: u_long -> u_int
- add `validbits,' which represents the valid data size in
precision bits. It is required in order to distinguish 24/32bit
from 24/24bit or 32/32bit.
* audio_hw_if
- add two parameters to set_params()
stream_filter_list_t *pfil, stream_filter_list *rfil
A HW driver should set filter recipes for requested formats
- constify audio_params parameters of trigger_output() and
trigger_input(). They represent audio formats for the hardware.
- make open() and close() optional
- add int (AUMODE_PLAY or AUMODE_RECORD) and audio_params_t parameters
to round_blocksize()
* sw_code is replaced with stream_filter_t.
stream_filer_t converts audio data in an input buffer and writes
into another output buffer unlike sw_code, which converts data in
single buffer.
converters in dev/auconv.c, dev/mulaw.c, dev/aurateconv.c,
dev/tc/bba.c, dev/ic/msm6258.c, and arch/arm/iomd/vidcaudio.c are
reimplemented as stream_filter_t
* MI audio
- audiosetinfo() builds filter pipelines from stream_filter_list_t
filled by audio_hw_if::set_params()
- audiosetinfo() returns with EINVAL if mmapped and set_params()
requests filters
- audio_write(), audio_pint(), and audio_rint() invoke a filter
pipeline.
- ioctl() for FIONREAD, AUDIO_WSEEK, AUDIO_GETIOFFS,
AUDIO_GETOOFFS, and audio_prinfo::{seek,samples} for
AUDIO_GETINFO handle values for a buffer nearest to userland.
* add `struct device *' parameter to ac97_attach()
* all of audio HW drivers follow audio_hw_if and ac97 changes
which bustype should be attached with a specific call to config_found()
(from a "mainbus" or a bus bridge).
Do it for isa/eisa/mca and pci/agp for now. These buses all attach to
an mi interface attribute "isabus", "eisabus" etc., and the autoconf
framework now allows to specify an interface attribute on config_found()
and config_search(), which limits the search of matching config data
to these which attach to that specific attribute.
So we basically have to call config_found_ia(..., "foobus", ...) where
such a bus is attached.
As a consequence, where a "mainbus" or alike also attaches other
devices (eg CPUs) which do not attach to a specific attribute yet,
we need at least pass an attribute name (different from "foobus") so
that the foo bus is not found at these places. This made some minor
changes necessary which are not obviously related to the mentioned buses.
Added software volume control functionality in vraiu_volume(), called from
vraiu_start(). Can be changed by the mixerctl 'inputs.dac' -- 0 is muted,
255 is the level that the driver previously outputted (quite loud on the
IBM Workpad Z50), and everything else is a smooth transition between the
two. Thanks to toddpw@ for lending me the hardware to test these changes.
enabled on amd64). Add a dmat64 field to various PCI attach structures,
and pass it down where needed. Implement a simple new function called
pci_dma64_available(pa) to test if 64bit DMA addresses may be used.
This returns 1 iff _PCI_HAVE_DMA64 is defined in <machine/pci_machdep.h>,
and there is more than 4G of memory.
===============================================
This code enables NetBSD to support for NEC VR4181 CPU and some
devices on L-Card+ board.
NEC VR4181
----------
NEC VR4181 is a embedded CPU which has MIPS processor core and
integrated I/O devices within a package. The basic architecture of
VR4181 is similar to other VR41xx family CPU. Some integrated devices
are compatible to another VR41xx series CPU and some are not.
VR4181 has integrated devices listed bellow:
- Two of 16550 compatible UART
- Compact Flash controller
- ISA bus controller
- Audio CODEC
- A/D converters
- LCD driver
- Touch panel controller
- General purpose I/O
L-Card+ Embedded CPU Board
--------------------------
L-Card+ is name card sized CPU board for embedded system. It is soled
by Laser5 (http://www.laser5.co.jp/) with Linux installed.
L-Card+ has following devices:
- 16Mbyte flash memory (Intel 28F128)
- 16Mbyte SDRAM
- CS8900A Ethernet controller and RJ45 port
- RS232C line driver and external connector
- Compact Flash socket
- A pair of Mezzanine connector for extension board
- Some on-board LEDs
Current Feature of This Code
----------------------------
Following devices are supported:
- UART (used for console)
- wi on Compact Flash socket
- cs (CS8900A)
- Flash memory (Intel 28F128 and Fujitsu MBM29LV160)
