Beta release of the rme96xx (driver for RME 96XX cards like the
"Hammerfall" and the "Hammerfall light")
Important: The driver module has to be installed on a freshly rebooted system,
otherwise the driver might not be able to acquire its buffers.
features:
- OSS programming interface (i.e. runs with standard OSS soundsoftware)
- OSS/Multichannel interface (OSS multichannel is done by just aquiring
more than 2 channels). The driver does not use more than one device
( yet .. this feature may be implemented later )
- more than one RME card supported
The driver uses a specific multichannel interface, which I will document
when the driver gets stable. (take a look at the defines in rme96xx.h,
which adds blocked multichannel formats i.e instead of
lrlrlrlr --> llllrrrr etc.
Use the "rmectrl" programm to look at the status of the card ..
or use xrmectrl, a GUI interface for the ctrl program.
What you can do with the rmectrl program is to set the stereo device for
OSS emulation (e.g. if you use SPDIF out).
You do:
./ctrl offset 24 24
which makes the stereo device use channels 25 and 26.
Guenter Geiger <geiger@epy.co.at>
copy the first part of the attached source code into rmectrl.c
and the second part into xrmectrl (or get the program from
http://gige.xdv.org/pages/soft/pages/rme)
to compile: gcc -o rmectrl rmectrl.c

* 11 May 2001: 0.4 fixed for SMP, included into kernel source tree
* 17 May 2001: 0.5 draining code didn't work on new cards
* 18 May 2001: 0.6 remove synchronize_irq() call
* 17 Jul 2001: 0.7 updated xrmectrl to make it work for newer cards
* 2 feb 2002: 0.8 fixed pci device handling, see below for patches from Heiko (Thanks!)
Marcus Meissner <Marcus.Meissner@caldera.de>
Modifications - Heiko Purnhagen <purnhage@tnt.uni-hannover.de>
HP20020108 fixed handling of "large" read()
HP20020116 towards REV 1.5 support, based on ALSA's card-rme9652.c
HP20020118 made mixer ioctl and handling of devices>1 more safe
HP20020201 fixed handling of "large" read() properly
added REV 1.5 S/P-DIF receiver support
SNDCTL_DSP_SPEED now returns the actual speed
* 10 Aug 2002: added synchronize_irq() again

- mixer mmap interface

- get rid of noise upon first open (why ??)
- allow multiple open(at least for read)
- allow multiple open (at least for read)
- allow multiple open for non overlapping regions
- recheck the multiple devices part (offsets of different devices, etc)
- do decent draining in _release --- done
- SMP support
