Install commands should not be used to specify soft dependencies among modules. When loading modules it's much better to have a softdep that modprobe knows what's being done than having to fork/exec another instance of modprobe to load the other module. By using a softdep user has also an option to remove the dependencies when removing the module (and if its refcount dropped to 0) Signed-off-by: Lucas De Marchi <lucas.demarchi@profusion.mobi> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Driver
|
|
------
|
|
|
|
Information about Audio Excel DSP 16 driver can be found in the source
|
|
file aedsp16.c
|
|
Please, read the head of the source before using it. It contain useful
|
|
information.
|
|
|
|
Configuration
|
|
-------------
|
|
|
|
The Audio Excel configuration, is now done with the standard Linux setup.
|
|
You have to configure the sound card (Sound Blaster or Microsoft Sound System)
|
|
and, if you want it, the Roland MPU-401 (do not use the Sound Blaster MPU-401,
|
|
SB-MPU401) in the main driver menu. Activate the lowlevel drivers then select
|
|
the Audio Excel hardware that you want to initialize. Check the IRQ/DMA/MIRQ
|
|
of the Audio Excel initialization: it must be the same as the SBPRO (or MSS)
|
|
setup. If the parameters are different, correct it.
|
|
I you own a Gallant's audio card based on SC-6600, activate the SC-6600 support.
|
|
If you want to change the configuration of the sound board, be sure to
|
|
check off all the configuration items before re-configure it.
|
|
|
|
Module parameters
|
|
-----------------
|
|
To use this driver as a module, you must configure some module parameters, to
|
|
set up I/O addresses, IRQ lines and DMA channels. Some parameters are
|
|
mandatory while some others are optional. Here a list of parameters you can
|
|
use with this module:
|
|
|
|
Name Description
|
|
==== ===========
|
|
MANDATORY
|
|
io I/O base address (0x220 or 0x240)
|
|
irq irq line (5, 7, 9, 10 or 11)
|
|
dma dma channel (0, 1 or 3)
|
|
|
|
OPTIONAL
|
|
mss_base I/O base address for activate MSS mode (default SBPRO)
|
|
(0x530 or 0xE80)
|
|
mpu_base I/O base address for activate MPU-401 mode
|
|
(0x300, 0x310, 0x320 or 0x330)
|
|
mpu_irq MPU-401 irq line (5, 7, 9, 10 or 0)
|
|
|
|
A configuration file in /etc/modprobe.d/ directory will have lines like this:
|
|
|
|
options opl3 io=0x388
|
|
options ad1848 io=0x530 irq=11 dma=3
|
|
options aedsp16 io=0x220 irq=11 dma=3 mss_base=0x530
|
|
|
|
Where the aedsp16 options are the options for this driver while opl3 and
|
|
ad1848 are the corresponding options for the MSS and OPL3 modules.
|
|
|
|
Loading MSS and OPL3 needs to pre load the aedsp16 module to set up correctly
|
|
the sound card. Installation dependencies must be written in configuration
|
|
files under /etc/modprobe.d/ directory:
|
|
|
|
softdep ad1848 pre: aedsp16
|
|
softdep opl3 pre: aedsp16
|
|
|
|
Then you must load the sound modules stack in this order:
|
|
sound -> aedsp16 -> [ ad1848, opl3 ]
|
|
|
|
With the above configuration, loading ad1848 or opl3 modules, will
|
|
automatically load all the sound stack.
|
|
|
|
Sound cards supported
|
|
---------------------
|
|
This driver supports the SC-6000 and SC-6600 based Gallant's sound card.
|
|
It don't support the Audio Excel DSP 16 III (try the SC-6600 code).
|
|
I'm working on the III version of the card: if someone have useful
|
|
information about it, please let me know.
|
|
For all the non-supported audio cards, you have to boot MS-DOS (or WIN95)
|
|
activating the audio card with the MS-DOS device driver, then you have to
|
|
<ctrl>-<alt>-<del> and boot Linux.
|
|
Follow these steps:
|
|
|
|
1) Compile Linux kernel with standard sound driver, using the emulation
|
|
you want, with the parameters of your audio card,
|
|
e.g. Microsoft Sound System irq10 dma3
|
|
2) Install your new kernel as the default boot kernel.
|
|
3) Boot MS-DOS and configure the audio card with the boot time device
|
|
driver, for MSS irq10 dma3 in our example.
|
|
4) <ctrl>-<alt>-<del> and boot Linux. This will maintain the DOS configuration
|
|
and will boot the new kernel with sound driver. The sound driver will find
|
|
the audio card and will recognize and attach it.
