/* * sound/opl3sa2.c * * A low level driver for Yamaha OPL3-SA2 and SA3 cards. * NOTE: All traces of the name OPL3-SAx have now (December 2000) been * removed from the driver code, as an email exchange with Yamaha * provided the information that the YMF-719 is indeed just a * re-badged 715. * * Copyright 1998-2001 Scott Murray * * Originally based on the CS4232 driver (in cs4232.c) by Hannu Savolainen * and others.

Lahaie Changed probing / attach code order * Scott Murray Added mixer support (Dec 03, 1998) * Scott Murray Changed detection code to be more forgiving, * added force option as last resort, * fixed ioctl return values. (Dec 30, 1998) * Scott Murray Simpler detection code should work all the time now * (with thanks to Ben Hutchings for the heuristic), * removed now unnecessary force option. (Jan 5, 1999) * Christoph Hellwig Adapted to module_init/module_exit (Mar 4, 2000) * Scott Murray Reworked SA2 versus SA3 mixer code, updated chipset * version detection code (again!). (Dec 5, 2000) * Scott Murray Adjusted master volume mixer scaling. (Dec 6, 2000) * Scott Murray Based on a patch by Joel Yliluoma (aka Bisqwit), * integrated wide mixer and adjusted mic, bass, treble * scaling. (Dec 6, 2000) * Scott Murray Based on a patch by Peter Englmaier, integrated * ymode and loopback options. (Dec 6, 2000) * Scott Murray Inspired by a patch by Peter Englmaier, and based on * what ALSA does, added initialization code for the * default DMA and IRQ settings. (Dec 6, 2000) * Scott Murray Added some more checks to the card detection code, * based on what ALSA does. (Dec 12, 2000) * Scott Murray Inspired by similar patches from John Fremlin, * Jim Radford, Mike Rolig, and Ingmar Steen, added 2.4 * ISA PnP API support, mainly based on bits from * sb_card.c and awe_wave.c. (Dec 12, 2000) * Scott Murray Some small cleanups to the init code output. * (Jan 7, 2001) * */ #include #include #include #include #include "sound_config.h" #include "ad1848.h" #include "mpu401.h" /* Useful control port indexes: */ #define OPL3SA2_SYS_CTRL 0x02 #define OPL3SA2_IRQ_CONFIG 0x03 #define OPL3SA2_DMA_CONFIG 0x06 #define OPL3SA2_MASTER_LEFT 0x07 #define OPL3SA2_MASTER_RIGHT 0x08 #define OPL3SA2_MIC 0x09 #define OPL3SA2_MISC 0x0A #define OPL3SA3_WIDE 0x14 #define OPL3SA3_BASS 0x15 #define OPL3SA3_TREBLE 0x16 /* Useful constants: */ #define DEFAULT_VOLUME 50 #define DEFAULT_MIC 50 #define DEFAULT_TIMBRE 0 /* For checking against what the card returns: */ #define VERSION_UNKNOWN 0 #define VERSION_YMF711 1 #define VERSION_YMF715 2 #define VERSION_YMF715B 3 #define VERSION_YMF715E 4 /* also assuming that anything > 4 but <= 7 is a 715E */ /* Chipset type constants for use below */ #define CHIPSET_UNKNOWN -1 #define CHIPSET_OPL3SA2 0 #define CHIPSET_OPL3SA3 1 #if defined CONFIG_ISAPNP || defined CONFIG_ISAPNP_MODULE #define OPL3SA2_CARDS_MAX 4 #else #define OPL3SA2_CARDS_MAX 1 #endif /* This should be pretty obvious */ static int opl3sa2_cards_num; /* = 0 */ /* What's my version(s)? */ static int chipset[OPL3SA2_CARDS_MAX] = { CHIPSET_UNKNOWN }; /* Oh well, let's just cache the name(s) */ static char chipset_name[OPL3SA2_CARDS_MAX][12]; /* Where's my mixer(s)? */ static int opl3sa2_mixer[OPL3SA2_CARDS_MAX] = { -1 }; /* Bag o' mixer data */ typedef struct opl3sa2_mixerdata_tag { unsigned short cfg_port; unsigned short padding; unsigned int volume_l; unsigned int volume_r; unsigned int mic; unsigned int bass_l; unsigned int bass_r; unsigned int treble_l; unsigned int treble_r; unsigned int wide_l; unsigned int wide_r; } opl3sa2_mixerdata; static opl3sa2_mixerdata opl3sa2_data[OPL3SA2_CARDS_MAX]; static struct address_info cfg[OPL3SA2_CARDS_MAX]; static struct address_info cfg_mss[OPL3SA2_CARDS_MAX]; static struct address_info cfg_mpu[OPL3SA2_CARDS_MAX]; /* Our parameters */ static int __initdata io = -1; static int __initdata mss_io = -1; static int __initdata mpu_io = -1; static int __initdata irq = -1; static int __initdata dma = -1; static int __initdata dma2 = -1; static int __initdata ymode = -1; static int __initdata loopback = -1; #if defined CONFIG_ISAPNP || defined CONFIG_ISAPNP_MODULE /* PnP specific parameters */ static int __initdata isapnp = 1; static int __initdata multiple = 1; /* PnP devices */ struct pci_dev* opl3sa2_dev[OPL3SA2_CARDS_MAX]; /* Whether said devices have been activated */ static int opl3sa2_activated[OPL3SA2_CARDS_MAX]; #else static int __initdata isapnp; /* = 0 */ static int __initdata multiple; /* = 0 */ #endif MODULE_DESCRIPTION("Module for OPL3-SA2 and SA3 sound cards (uses AD1848 MSS driver)."); MODULE_AUTHOR("Scott Murray "); MODULE_PARM(io, "i"); MODULE_PARM_DESC(io, "Set I/O base of OPL3-SA2 or SA3 card (usually 0x370.
