select/poll and DEVFS changes, which are limited to an include/define in sound.h and the actual select/poll implementation in sound.c [ This commit is blind, but the code is similar enough that there will hopefully be no problems. ]

In this file I will try to build a database of cards supported by this
|
|
driver. I also include the command to use for manual configuration of
|
|
the card in case your BIOS is not PnP-aware. Of course it is your
|
|
responsibility to pick up free prot ranges and irq and drq channels.
|
|
|
|
For PnP cards, I also include the vendor_id and serial numbers of
|
|
cards I have encountered. Underscores in the PnP id mean that there is
|
|
a large variety of values in those positions.
|
|
|
|
Finally, where available, I have put the URL where you can find the
|
|
data sheets of the chip.

|
|
|
work like a charm. All modes, including full duplex, supported in
|
|
MSS mode.
|
|
|
|
NOTE: cards based on the 4237, and possibly the 4236 as well,
|
|
connect the CD to AUX2. When used in MODE1/2 (as this driver
|
|
does) there is no route in the input mixer from AUX2 to the
|
|
ADC. So, to record directly from the CD, the only way is
|
|
to set the input to SOUND_MASK_IMIX.

This chip is reported as broken in the OSS documentation. As a
|
|
matter of fact, on my Intel Zappa motherboard, I have problems in
|
|
make it use the secondary DMA channel. I have it working in
|
|
half duplex (both capture and playback) in SB3.2 emulation,
|
|
and working in playback mode in MSS emulation.
|
|
Also have reports from some user that it works ok.

pnp 1 1 os enable port0 0x534 port2 0x220 port3 0xe0d irq0 10 drq0 1 drq1 6
|
|
|
|
The data sheets of this chip are very cryptic and do not match
|
|
what the cards I have seem to do. I have it working
|
|
in WSS emulation, in full duplex and all modes.
|
|
In SB emulation mode the driver does not work yet (maybe I do
|
|
not initialize it the right way). It is not a major concern
|
|
anyways.
|
|
I am strongly convinced of a couple of bugs in the chip. I have
|
|
sent email to OPTI but got no reply so far. The bugs are:
|
|
- you cannot set both playback and capture format to use
|
|
a companded mode (ULAW, ALAW). If you do, the card will screw
|
|
up on the capture section.
|
|
The driver has a partial fix in software: when using ULAW, it
|
|
programs ULAW on the playback section, U8 on the capture, and
|
|
does a conversion in software (much like the SBPro). Of course
|
|
you lose 4-5 bits of dynamic range in the process.
|
|
- in full duplex (and single DMA mode), the card occasionally
|
|
misses interrupts, or generates spurious ones. Spurious ints are
|
|
not problematic since they can be ignored, but missed ones are
|
|
as you can imagine... This is fixed by auto-dma mode.

SB16 PnP: PnP id 0x__008c0e

|
|
|
|
pnp 1 0 os enable port0 0x220 irq0 5 drq0 1 drq1 5
|
|
|
|
There are many such cards (plain SB16 PnP, AWE32, AWE64, Vibra16,
|
|
etc.) all differing in the PnP id. They have different synthesis
|
|
devices, which we do not support, so we are not affected by these
|
|
differences. Don't worry if the driver identifies the card as a
|
|
different SB16 than the one you have.
|
|
|
|
Full duplex support of this card is tricky since one channel can
|
|
work in 16-bit and the other in 8-bit mode. You will need to use
|
|
the new set of ioctl to use separate data formats on the two
|
|
channels (the vat driver does this). Of course, quality in 8-bit
|
|
is much lower than in 16-bit.
|
|
|
|
Full duplex operation is unsupported by Creative. It seems to
|
|
work, although on my Vibra16 the command to stop DMA transfer
|
|
seems to erroneously affect both channels instead of the one
|
|
they are issued for. The driver has a workaround, but I cannot
|
|
guarantee that it works for everybody. I have had several
|
|
positive reports.
|
|
|
|
Some docs on how to use this card with the voxware driver
|
|
are at http://multiverse.com/~rhh/awedrv
|
|
|
|
NOTE: 980122 I have had a couple of reports from people using
|
|
the Vibra16X (and clones, e.g. based on the Avance Logic
|
|
chipsets) which appears to use two 8-bit DMA channels. It
|
|
might be possible that new SB16 are able to do true full duplex!
|
|
The driver _does not_ support these boards although the fix
|
|
should be relatively easy.
|
|
|
|
ASound:
|
|
Avance Logic makes SB clones, and apparently documentation
|
|
is available at
|
|
|
|
http://www.realtek.com.tw/cp/cp.html
|
|
|
|
these card should be recognised as SB16 clones.

pnp 1 0 os enable port0 0x220 port1 0x530 irq0 5 drq0 1 drq1 5
|
|
|
|
this card emulates a WSS or SB. Have reports that it works, although
|
|
it has incomplete mixer support (Yamaha defines an additional set
|
|
of registers to control some mixer functions, such as the master
|
|
output volume). Currently we set the master volume to 100%.

It works in U8 and S16 mode, ulaw support still not working.

NOT WORKING YET:

OPTI925: PnP id 0x2509143e
|

there is code to recognize it as a SB clone. I have reports that
|
|
it probes ok, but not sure if it works.

|
OPTI924: PnP
|
|
|
|
I have this card but it is still unsupported.
|
|
|
|
OPTI930:
|
|
|
|
should work as an MSS clone, but support for it is not implemented
|
|
yet.

There used to be documentation for the 1868 on the ESS site
|
|
(files ds1868b1.pdf and ds1868b2.pdf) but I am unable to find
|
|
it now (980122). I have asked ESS but no reply so far.
|
|
|
|
partly supported in SB emulation.
|
|
|
|
(the ESS688 is used on many notebooks. It is probably able to do 8
|
|
and 16-bit, half duplex).
|
|
|
|
PCI cards:
|
|
|
|
some vendors have PCI cards. This code _cannot_ work on these
|
|
cards as it is now, since they cannot obviously use the ISA DMA
|
|
controller. As there are no data sheets available for these PCI
|
|
cards, none of them is supported at the moment, although support
|
|
should be easy as soon as I can put my hands on the data sheets
|
|
and cards.
