Many user space API headers have licensing information, which is either
incomplete, badly formatted or just a shorthand for referring to the
license under which the file is supposed to be. This makes it hard for
compliance tools to determine the correct license.
Update these files with an SPDX license identifier. The identifier was
chosen based on the license information in the file.
GPL/LGPL licensed headers get the matching GPL/LGPL SPDX license
identifier with the added 'WITH Linux-syscall-note' exception, which is
the officially assigned exception identifier for the kernel syscall
exception:
NOTE! This copyright does *not* cover user programs that use kernel
services by normal system calls - this is merely considered normal use
of the kernel, and does *not* fall under the heading of "derived work".
This exception makes it possible to include GPL headers into non GPL
code, without confusing license compliance tools.
Headers which have either explicit dual licensing or are just licensed
under a non GPL license are updated with the corresponding SPDX
identifier and the GPLv2 with syscall exception identifier. The format
is:
((GPL-2.0 WITH Linux-syscall-note) OR SPDX-ID-OF-OTHER-LICENSE)
SPDX license identifiers are a legally binding shorthand, which can be
used instead of the full boiler plate text. The update does not remove
existing license information as this has to be done on a case by case
basis and the copyright holders might have to be consulted. This will
happen in a separate step.
This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne. See the previous patch in this series for the
methodology of how this patch was researched.

* Format:

* byte 1 - Synthesizer device number (0-N)
|
|
* byte 2 - Command (see below)
|

|
* Commands:
|
|
* Each command affects one voice defined in byte 3.
|
|
* Unused parameters (P1 and/or P2 *MUST* be initialized to zero).
|
|
* _GUS_NUMVOICES - Sets max. number of concurrent voices (P1=14-31, default 16)

|
* _GUS_VOICESAMPLE- ************ OBSOLETE *************
|
|
* _GUS_VOICEON - Starts voice (P1=voice mode)
|
|
* _GUS_VOICEOFF - Stops voice (no parameters)
|
|
* _GUS_VOICEFADE - Stops the voice smoothly.
|
|
* _GUS_VOICEMODE - Alters the voice mode, don't start or stop voice (P1=voice mode)
|
|
* _GUS_VOICEBALA - Sets voice balance (P1, 0=left, 7=middle and 15=right, default 7)
|
|
* _GUS_VOICEFREQ - Sets voice (sample) playback frequency (P1=Hz)
|
|
* _GUS_VOICEVOL - Sets voice volume (P1=volume, 0xfff=max, 0xeff=half, 0x000=off)
|
|
* _GUS_VOICEVOL2 - Sets voice volume (P1=volume, 0xfff=max, 0xeff=half, 0x000=off)
|
|
* (Like GUS_VOICEVOL but doesn't change the hw
|
|
* volume. It just updates volume in the voice table).

|
*
|
|
* _GUS_RAMPRANGE - Sets limits for volume ramping (P1=low volume, P2=high volume)
|
|
* _GUS_RAMPRATE - Sets the speed for volume ramping (P1=scale, P2=rate)
|
|
* _GUS_RAMPMODE - Sets the volume ramping mode (P1=ramping mode)
|
|
* _GUS_RAMPON - Starts volume ramping (no parameters)
|
|
* _GUS_RAMPOFF - Stops volume ramping (no parameters)
