This means +that it compiles and runs, and that I use it on my system (Linux +2.1.106) with some reasonably demanding applications and uses. I +believe the code is approaching an initial "finished" state that +provides bug-free support for the Tropez Plus. + +Please note that to date, the driver has ONLY been tested on a Tropez +Plus. I would very much like to hear (and help out) people with Tropez +and Maui cards, since I think the driver can support those cards as +well. + +Finally, the driver has not been tested (or even compiled) as a static +(non-modular) part of the kernel. Alan Cox's good work in modularizing +OSS/Free for Linux makes this rather unnecessary. + +Some Questions +-------------- + +********************************************************************** +0) What does this driver do that the maui driver did not ? +********************************************************************** + +* can fully initialize a WaveFront card from cold boot - no DOS + utilities needed +* working patch/sample/program loading and unloading (the maui + driver didn't document how to make this work, and assumed + user-level preparation of the patch data for writing + to the board. ick.) +* full user-level access to all WaveFront commands +* for the Tropez Plus, (primitive) control of the YSS225 FX processor +* Virtual MIDI mode supported - 2 MIDI devices accessible via the + WaveFront's MPU401/UART emulation. One + accesses the WaveFront synth, the other accesses the + external MIDI connector. Full MIDI read/write semantics + for both devices. +* OSS-compliant /dev/sequencer interface for the WaveFront synth, + including native and GUS-format patch downloading. +* semi-intelligent patch management (prototypical at this point) + +********************************************************************** +1) What to do about MIDI interfaces ? +********************************************************************** + +The Tropez Plus (and perhaps other WF cards) can in theory support up +to 2 physical MIDI interfaces. One of these is connected to the +ICS2115 chip (the WaveFront synth itself) and is controlled by +MPU/UART-401 emulation code running as part of the WaveFront OS. The +other is controlled by the CS4232 chip present on the board. However, +physical access to the CS4232 connector is difficult, and it is +unlikely (though not impossible) that you will want to use it. + +An older version of this driver introduced an additional kernel config +variable which controlled whether or not the CS4232 MIDI interface was +configured. Because of Alan Cox's work on modularizing the sound +drivers, and now backporting them to 2.0.34 kernels, there seems to be +little reason to support "static" configuration variables, and so this +has been abandoned in favor of *only* module parameters. Specifying +"mpuio" and "mpuirq" for the cs4232 parameter will result in the +CS4232 MIDI interface being configured; leaving them unspecified will +leave it unconfigured (and thus unusable). + +BTW, I have heard from one Tropez+ user that the CS4232 interface is +more reliable than the ICS2115 one. I have had no problems with the +latter, and I don't have the right cable to test the former one +out. Reports welcome. + +********************************************************************** +2) Why does line XXX of the code look like this .... ? +********************************************************************** + +Either because it's not finished yet, or because you're a better coder +than I am, or because you don't understand some aspect of how the card +or the code works. + +I absolutely welcome comments, criticisms and suggestions about the +design and implementation of the driver. + +********************************************************************** +3) What files are included ? +********************************************************************** + + drivers/sound/README.wavefront -- this file + + drivers/sound/wavefront.patch -- patches for the 2.1.106 sound drivers + needed to make the rest of this work + DO NOT USE IF YOU'VE APPLIED THEM + BEFORE, OR HAVE 2.1.109 OR ABOVE + + drivers/sound/wavfront.c -- the driver + drivers/sound/ys225.h -- data declarations for FX config + drivers/sound/ys225.c -- data definitions for FX config + drivers/sound/wf_midi.c -- the "uart401" driver + to support virtual MIDI mode. + include/wavefront.h -- the header file + Documentation/sound/oss/Tropez+ -- short docs on configuration + +********************************************************************** +4) How do I compile/install/use it ? +********************************************************************** + +PART ONE: install the source code into your sound driver directory + + cd <top-of-your-2.1.106-code-base-e.g.-/usr/src/linux> + tar -zxvf <where-you-put/wavefront.tar.gz> + +PART TWO: apply the patches + + DO THIS ONLY IF YOU HAVE A KERNEL VERSION BELOW 2.1.109 + AND HAVE NOT ALREADY INSTALLED THE PATCH(ES). + + cd drivers/sound + patch < wavefront.patch + +PART THREE: configure your kernel + + cd <top of your kernel tree> + make xconfig (or whichever config option you use) + + - choose YES for Sound Support + - choose MODULE (M) for OSS Sound Modules + - choose MODULE(M) to YM3812/OPL3 support + - choose MODULE(M) for WaveFront support + - choose MODULE(M) for CS4232 support + + - choose "N" for everything else (unless you have other + soundcards you want support for) + + + make boot + . + . + . + <whatever you normally do for a kernel install> + make modules + . + . + . + make modules_install + +Here's my autoconf.h SOUND section: + +/* + * Sound + */ +#define CONFIG_SOUND 1 +#undef CONFIG_SOUND_OSS +#define CONFIG_SOUND_OSS_MODULE 1 +#undef CONFIG_SOUND_PAS +#undef CONFIG_SOUND_SB +#undef CONFIG_SOUND_ADLIB +#undef CONFIG_SOUND_GUS +#undef CONFIG_SOUND_MPU401 +#undef CONFIG_SOUND_PSS +#undef CONFIG_SOUND_MSS +#undef CONFIG_SOUND_SSCAPE +#undef CONFIG_SOUND_TRIX +#undef CONFIG_SOUND_MAD16 +#undef CONFIG_SOUND_WAVEFRONT +#define CONFIG_SOUND_WAVEFRONT_MODULE 1 +#undef CONFIG_SOUND_CS4232 +#define CONFIG_SOUND_CS4232_MODULE 1 +#undef CONFIG_SOUND_MAUI +#undef CONFIG_SOUND_SGALAXY +#undef CONFIG_SOUND_OPL3SA1 +#undef CONFIG_SOUND_SOFTOSS +#undef CONFIG_SOUND_YM3812 +#define CONFIG_SOUND_YM3812_MODULE 1 +#undef CONFIG_SOUND_VMIDI +#undef CONFIG_SOUND_UART6850 +/* + * Additional low level sound drivers + */ +#undef CONFIG_LOWLEVEL_SOUND + +************************************************************ +6) How do I configure my card ? +************************************************************ + +You need to edit /etc/modprobe.conf.

However, if you have a WaveFront card, then you +almost certainly have the firmware, and if not, its freely available +on their website, at: + + http://www.tbeach.com/tbs/downloads/scardsdown.htm#tropezplus + +The file is called WFOS2001.MOT (for the Tropez+). + +This driver, however, doesn't use the pure firmware as distributed, +but instead relies on a somewhat processed form of it. You can +generate this very easily. Following an idea from Andrew Veliath's +Pinnacle driver, the following flex program will generate the +processed version: + +---- cut here ------------------------- +%option main +%% +^S[28].*\r$ printf ("%c%.*s", yyleng-1,yyleng-1,yytext); +<<EOF>> { fputc ('\0', stdout); return; } +\n {} +. {} +---- cut here ------------------------- + +To use it, put the above in file (say, ws.l) compile it like this: + + shell> flex -ows.c ws.l + shell> cc -o ws ws.c + +and then use it like this: + + ws < my-copy-of-the-oswf.mot-file > /etc/sound/wavefront.os + +If you put it somewhere else, you'll always have to use the wf_ospath +module parameter (see below) or alter the source code. + +********************************************************************** +7) How do I get it working ? +********************************************************************** + +Optionally, you can reboot with the "new" kernel (even though the only +changes have really been made to a module). + +Then, as root do: + + modprobe wavefront + +You should get something like this in /var/log/messages: + + WaveFront: firmware 1.20 already loaded. + +or + + WaveFront: no response to firmware probe, assume raw. + +then: + + WaveFront: waiting for memory configuration ... + WaveFront: hardware version 1.64 + WaveFront: available DRAM 8191k + WaveFront: 332 samples used (266 real, 13 aliases, 53 multi), 180 empty + WaveFront: 128 programs slots in use + WaveFront: 256 patch slots filled, 142 in use + +The whole process takes about 16 seconds, the longest waits being +after reporting the hardware version (during the firmware download), +and after reporting program status (during patch status inquiry). Its +shorter (about 10 secs) if the firmware is already loaded (i.e. only +warm reboots since the last firmware load). + +The "available DRAM" line will vary depending on how much added RAM +your card has. Mine has 8MB. + +To check basically functionality, use play(1) or splay(1) to send a +.WAV or other audio file through the audio portion. Then use playmidi +to play a General MIDI file. Try the "-D 0" to hear the +difference between sending MIDI to the WaveFront and using the OPL/3, +which is the default (I think ...). If you have an external synth(s) +hooked to the soundcard, you can use "-e" to route to the +external synth(s) (in theory, -D 1 should work as well, but I think +there is a bug in playmidi which prevents this from doing what it +should). + +********************************************************************** +8) What are the module parameters ? +********************************************************************** + +Its best to read wavefront.c for this, but here is a summary: + +integers: + wf_raw - if set, ignore apparent presence of firmware + loaded onto the ICS2115, reset the whole + board, and initialize it from scratch. (default = 0) + + fx_raw - if set, always initialize the YSS225 processor + on the Tropez plus. (default = 1) + + < The next 4 are basically for kernel hackers to allow + tweaking the driver for testing purposes. > + + wait_usecs - loop timer used when waiting for + status conditions on the board. + The default is 150. + + debug_default - debugging flags. See sound/wavefront.h + for WF_DEBUG_* values. Default is zero. + Setting this allows you to debug the + driver during module installation. +strings: + ospath - path to get to the pre-processed OS firmware. + (default: /etc/sound/wavefront.os) + +********************************************************************** +9) Who should I contact if I have problems? +********************************************************************** + +Just me: Paul Barton-Davis <pbd@op.net> + + |
