Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

This file contains notes for users of PSS sound cards who wish to use the
|
|
newly added features of the newest version of this driver.
|
|
|
|
The major enhancements present in this new revision of this driver is the
|
|
addition of two new module parameters that allow you to take full advantage of
|
|
all the features present on your PSS sound card. These features include the
|
|
ability to enable both the builtin CDROM and joystick ports.
|
|
|
|
pss_enable_joystick
|
|
|
|
This parameter is basically a flag. A 0 will leave the joystick port
|
|
disabled, while a non-zero value would enable the joystick port. The default
|
|
setting is pss_enable_joystick=0 as this keeps this driver fully compatible
|
|
with systems that were using previous versions of this driver. If you wish to
|
|
enable the joystick port you will have to add pss_enable_joystick=1 as an
|
|
argument to the driver. To actually use the joystick port you will then have
|
|
to load the joystick driver itself. Just remember to load the joystick driver
|
|
AFTER the pss sound driver.
|
|
|
|
pss_cdrom_port
|
|
|
|
This parameter takes a port address as its parameter. Any available port
|
|
address can be specified to enable the CDROM port, except for 0x0 and -1 as
|
|
these values would leave the port disabled. Like the joystick port, the cdrom
|
|
port will require that an appropriate CDROM driver be loaded before you can make
|
|
use of the newly enabled CDROM port. Like the joystick port option above,
|
|
remember to load the CDROM driver AFTER the pss sound driver. While it may
|
|
differ on some PSS sound cards, all the PSS sound cards that I have seen have a
|
|
builtin Wearnes CDROM port. If this is the case with your PSS sound card you
|
|
should load aztcd with the appropriate port option that matches the port you
|
|
assigned to the CDROM port when you loaded your pss sound driver. (ex.
|
|
modprobe pss pss_cdrom_port=0x340 && modprobe aztcd aztcd=0x340) The default
|
|
setting of this parameter leaves the CDROM port disabled to maintain full
|
|
compatibility with systems using previous versions of this driver.
|
|
|
|
Other options have also been added for the added convenience and utility
|
|
of the user. These options are only available if this driver is loaded as a
|
|
module.
|
|
|
|
pss_no_sound
|
|
|
|
This module parameter is a flag that can be used to tell the driver to
|
|
just configure non-sound components. 0 configures all components, a non-0
|
|
value will only attept to configure the CDROM and joystick ports. This
|
|
parameter can be used by a user who only wished to use the builtin joystick
|
|
and/or CDROM port(s) of his PSS sound card. If this driver is loaded with this
|
|
parameter and with the parameter below set to true then a user can safely unload
|
|
this driver with the following command "rmmod pss && rmmod ad1848 && rmmod
|
|
mpu401 && rmmod sound && rmmod soundcore" and retain the full functionality of
|
|
his CDROM and/or joystick port(s) while gaining back the memory previously used
|
|
by the sound drivers. This default setting of this parameter is 0 to retain
|
|
full behavioral compatibility with previous versions of this driver.
|
|
|
|
pss_keep_settings
|
|
|
|
This parameter can be used to specify whether you want the driver to reset
|
|
all emulations whenever its unloaded. This can be useful for those who are
|
|
sharing resources (io ports, IRQ's, DMA's) between different ISA cards. This
|
|
flag can also be useful in that future versions of this driver may reset all
|
|
emulations by default on the driver's unloading (as it probably should), so
|
|
specifying it now will ensure that all future versions of this driver will
|
|
continue to work as expected. The default value of this parameter is 1 to
|
|
retain full behavioral compatibility with previous versions of this driver.
|
|
|
|
pss_firmware
|
|
|
|
This parameter can be used to specify the file containing the firmware
|
|
code so that a user could tell the driver where that file is located instead
|
|
of having to put it in a predefined location with a predefined name. The
|
|
default setting of this parameter is "/etc/sound/pss_synth" as this was the
|
|
path and filename the hardcoded value in the previous versions of this driver.
|
|
|
|
Examples:
|
|
|
|
# Normal PSS sound card system, loading of drivers.
|
|
# Should be specified in an rc file (ex. Slackware uses /etc/rc.d/rc.modules).
|
|
|
|
/sbin/modprobe pss pss_io=0x220 mpu_io=0x338 mpu_irq=9 mss_io=0x530 mss_irq=10 mss_dma=1 pss_cdrom_port=0x340 pss_enable_joystick=1
|
|
/sbin/modprobe aztcd aztcd=0x340
|
|
/sbin/modprobe joystick
|
|
|
|
# System using the PSS sound card just for its CDROM and joystick ports.
|
|
# Should be specified in an rc file (ex. Slackware uses /etc/rc.d/rc.modules).
|
|
|
|
/sbin/modprobe pss pss_io=0x220 pss_cdrom_port=0x340 pss_enable_joystick=1 pss_no_sound=1
|
|
/sbin/rmmod pss && /sbin/rmmod ad1848 && /sbin/rmmod mpu401 && /sbin/rmmod sound && /sbin/rmmod soundcore # This line not needed, but saves memory.

|
/sbin/modprobe aztcd aztcd=0x340
