It contains an 36 * ALS100-like SB DSP/mixer, an OPL3 synth, a MPU401 and a gameport 37 * interface. These subsystems can be mapped into ISA io-port space, 38 * using the PCI-interface. In addition, the PCI-bit provides DMA and IRQ 39 * services to the subsystems. 40 * 41 * While ALS4000 is very similar to a SoundBlaster, the differences in 42 * DMA and capturing require more changes to the SoundBlaster than 43 * desirable, so I made this separate driver. 44 * 45 * The ALS4000 can do real full duplex playback/capture. 46 * 47 * FMDAC: 48 * - 0x4f -> port 0x14 49 * - port 0x15 |= 1 50 * 51 * Enable/disable 3D sound: 52 * - 0x50 -> port 0x14 53 * - change bit 6 (0x40) of port 0x15 54 * 55 * Set QSound: 56 * - 0xdb -> port 0x14 57 * - set port 0x15: 58 * 0x3e (mode 3), 0x3c (mode 2), 0x3a (mode 1), 0x38 (mode 0) 59 * 60 * Set KSound: 61 * - value -> some port 0x0c0d 62 * 63 * ToDo: 64 * - by default, don't enable legacy game and use PCI game I/O 65 * - power management? (card can do voice wakeup according to datasheet!!) 66 */ 67 68#include <asm/io.h> 69#include <linux/init.h> 70#include <linux/pci.h> 71#include <linux/gameport.h> 72#include <linux/moduleparam.h> 73#include <linux/dma-mapping.h> 74#include <sound/core.h> 75#include <sound/pcm.h> 76#include <sound/rawmidi.h> 77#include <sound/mpu401.h> 78#include <sound/opl3.h> 79#include <sound/sb.h> 80#include <sound/initval.h> 81 82MODULE_AUTHOR("Bart Hartgers <bart@etpmod.phys.tue.nl>, Andreas Mohr"); 83MODULE_DESCRIPTION("Avance Logic ALS4000"); 84MODULE_LICENSE("GPL"); 85MODULE_SUPPORTED_DEVICE("{{Avance Logic,ALS4000}}"); 86 87#if defined(CONFIG_GAMEPORT) || (defined(MODULE) && defined(CONFIG_GAMEPORT_MODULE)) 88#define SUPPORT_JOYSTICK 1 89#endif 90 91static int index[SNDRV_CARDS] = SNDRV_DEFAULT_IDX; /* Index 0-MAX */ 92static char *id[SNDRV_CARDS] = SNDRV_DEFAULT_STR; /* ID for this card */ 93static int enable[SNDRV_CARDS] = SNDRV_DEFAULT_ENABLE_PNP; /* Enable this card */ 94#ifdef SUPPORT_JOYSTICK 95static int joystick_port[SNDRV_CARDS]; 96#endif 97 98module_param_array(index, int, NULL, 0444); 99MODULE_PARM_DESC(index, "Index value for ALS4000 soundcard."); 100module_param_array(id, charp, NULL, 0444); 101MODULE_PARM_DESC(id, "ID string for ALS4000 soundcard."); 102module_param_array(enable, bool, NULL, 0444); 103MODULE_PARM_DESC(enable, "Enable ALS4000 soundcard."); 104#ifdef SUPPORT_JOYSTICK 105module_param_array(joystick_port, int, NULL, 0444); 106MODULE_PARM_DESC(joystick_port, "Joystick port address for ALS4000 soundcard.
