《嵌入式系统设计与实例开发实验教材二源码》Linux内核移植与编译实验

1998-12-04  Andrew T. Veliath  <[e-mail]>

	* Update version to 0.8.2.2

	* Add msndreset program to shell archive.

1998-11-11  Andrew T. Veliath  <[e-mail]>

	* msnd_pinnacle.c (mixer_ioctl): Add a mixer ioctl for
	SOUND_MIXER_PRIVATE1 which does a full reset on the card.
	(mixer_set): Move line in recording source to input monitor, aux
	input level added, some mixer fixes.

1998-09-10  Andrew Veliath  <[e-mail]>

	* Update version to 0.8.2

	* Add SNDCTL_DSP_GETOSPACE and SNDCTL_DSP_GETISPACE ioctls.

1998-09-09  Andrew Veliath  <[e-mail]>

	* Update version to 0.8.1
	
	* msnd_pinnacle.c: Fix resetting of default audio parameters. Turn
	flush code from dsp_halt into dsp_write_flush, and use that for
	SNDCTL_DSP_SYNC.

1998-09-07  Andrew Veliath  <[e-mail]>

	* Update version to 0.8.0

	* Provide separate signal parameters for play and record.
	
	* Cleanups to locking and interrupt handling, change default
	fifosize to 128kB.

	* Update version to 0.7.15

	* Interprocess full-duplex support (ie `cat /dev/dsp > /dev/dsp').

	* More mutex sections for read and write fifos (read + write locks
	added).

1998-09-05  Andrew Veliath  <[e-mail]>

	* msnd_pinnacle.c: (chk_send_dsp_cmd) Do full DSP reset upon DSP
	timeout (when not in interrupt; maintains mixer settings).  Fixes
	to flushing and IRQ ref counting. Rewrote queuing for smoother
	playback and fixed initial playback cutoff problem.

1998-09-03  Andrew Veliath  <[e-mail]>

	* Replaced packed structure accesses with standard C equivalents.

1998-09-01  Andrew Veliath  <[e-mail]>

	* msnd_pinnacle.c: Add non-PnP configuration to driver code, which
	  will facilitate compiled-in operation.

1998-08-29  Andrew Veliath  <[e-mail]>

	* Update version to 0.7.6
	
	* msnd_pinnacle.c (dsp_ioctl): Add DSP_GETFMTS, change SAMPLESIZE
	  to DSP_SETFMT.

	* Update version to 0.7.5
	
	* Create pinnaclecfg.c and turn MultiSound doc into a shell
	  archive with pinnaclecfg.c included.  pinnaclecfg.c can
	  now fully configure the card in non-PnP mode, including the
	  joystick and IDE controller.  Also add an isapnp conf
	  example.

	* Reduce DSP reset timeout from 20000 to 100

1998-08-06  Andrew Veliath  <[e-mail]>

	* Update version to 0.7.2
	
	* After A/D calibration, do an explicit set to the line input,
	  rather than using set_recsrc

1998-07-20  Andrew Veliath  <[e-mail]>

	* Update version to 0.7.1

	* Add more OSS ioctls
	
1998-07-19  Andrew Veliath  <[e-mail]>

	* Update doc file
	
	* Bring back DIGITAL1 with digital parameter to msnd_pinnacle.c
	  and CONFIG_MSNDPIN_DIGITAL.  I'm not sure this actually works,
	  since I find audio playback goes into a very speeded mode of
	  operation, however it might be due to a lack of a digital
	  source, which I don't have to test.

1998-07-18  Andrew Veliath  <[e-mail]>

	* Update version to 0.7.0

	* Can now compile with Alan Cox' 2.0.34-modular-sound patch (so
	  now it requires >= 2.1.106 or 2.0.34-ms) (note for 2.0.34-ms it
	  is in the Experimental section)

	* More modularization, consolidation, also some MIDI hooks
	  installed for future MIDI modules

	* Write flush

	* Change default speed, channels, bit size to OSS/Free defaults

1998-06-02  Andrew Veliath  <[e-mail]>

	* Update version to 0.5b

	* Fix version detection
	
	* Remove underflow and overflow resets (delay was too long)

	* Replace spinlocked bitops with atomic bit ops

1998-05-27  Andrew Veliath  <[e-mail]>

	* Update version to 0.5a
	
	* Better recovery from underflow or overflow conditions
	
	* Fix a deadlock condition with one thread reading and the other
	  writing

1998-05-26  Andrew Veliath  <[e-mail]>

	* Update version to 0.5
	
	* Separate reset queue functions for play and record

	* Add delays in dsp_halt

1998-05-24  Andrew Veliath  <[e-mail]>

	* Add a check for Linux >= 2.1.95
	
	* Remove DIGITAL1 input until I figure out how to make it work
	
	* Add HAVE_DSPCODEH which when not defined will load firmware from
	  files using mod_firmware_load, then release memory after they
	  are uploaded (requires reorganized OSS).

1998-05-22  Andrew Veliath  <[e-mail]>

	* Update version to 0.4c

	* Hopefully fix the mixer volume problem

1998-05-19  Andrew Veliath  <[e-mail]>

	* Add __initfuncs and __initdatas to reduce resident code size

	* Move bunch of code around, remove some protos

	* Integrate preliminary changes for Alan Cox's OSS reorganization
	  for non-OSS drivers to coexist with OSS devices on the same
	  major.  To compile standalone, must now define STANDALONE.

1998-05-16  Andrew Veliath  <[e-mail]>

	* Update version to 0.4b
	
	* Integrated older card support into a unified driver, tested on a
	  MultiSound Classic c/o Kendrick Vargas.

1998-05-15  Andrew Veliath  <[e-mail]>

	* Update version to 0.4
	
	* Fix read/write return values

1998-05-13  Andrew Veliath  <[e-mail]>

	* Update version to 0.3

	* Stop play gracefully

	* Add busy flag
	
	* Add major and calibrate_signal module parameters
	
	* Add ADC calibration

	* Add some OSS compatibility ioctls

	* Add mixer record selection
	
	* Add O_NONBLOCK support, separate read/write wait queues

	* Add sample bit size ioctl, expanded sample rate ioctl

	* Playback suspension now resumes

	* Use signal_pending after interruptible_sleep_on
	
	* Add recording, change ints to bit flags

1998-05-11  Andrew Veliath  <[e-mail]>

	* Update version to 0.2

	* Add preliminary playback support

	* Use new Turtle Beach DSP code
