Now interrupt per period, instead of half period. 25 * 0.13 26 * Use single trigger for multichannel. 27 * 0.14 28 * Mic capture now works at fixed: S32_LE, 96000Hz, Stereo. 29 * 0.15 30 * Force buffer_size / period_size == INTEGER. 31 * 0.16 32 * Update p16v.c to work with changed alsa api. 33 * 0.17 34 * Update p16v.c to work with changed alsa api. Removed boot_devs. 35 * 0.18 36 * Merging with snd-emu10k1 driver. 37 * 0.19 38 * One stereo channel at 24bit now works. 39 * 0.20 40 * Added better register defines. 41 * 0.21 42 * Integrated with snd-emu10k1 driver. 43 * 0.22 44 * Removed #if 0 ... #endif 45 * 0.23 46 * Implement different capture rates. 47 * 0.24 48 * Implement different capture source channels. 49 * e.g. When HD Capture source is set to SPDIF, 50 * setting HD Capture channel to 0 captures from CDROM digital input. 51 * setting HD Capture channel to 1 captures from SPDIF in. 52 * 0.25 53 * Include capture buffer sizes. 54 * 55 * BUGS: 56 * Some stability problems when unloading the snd-p16v kernel module. 57 * -- 58 * 59 * TODO: 60 * SPDIF out. 61 * Find out how to change capture sample rates. E.g. To record SPDIF at 48000Hz. 62 * Currently capture fixed at 48000Hz. 63 * 64 * -- 65 * GENERAL INFO: 66 * Model: SB0240 67 * P16V Chip: CA0151-DBS 68 * Audigy 2 Chip: CA0102-IAT 69 * AC97 Codec: STAC 9721 70 * ADC: Philips 1361T (Stereo 24bit) 71 * DAC: CS4382-K (8-channel, 24bit, 192Khz) 72 * 73 * This code was initially based on code from ALSA's emu10k1x.c which is: 74 * Copyright (c) by Francisco Moraes <fmoraes@nc.rr.com> 75 */ 76 #include <linux/delay.h> 77 #include <linux/init.h> 78 #include <linux/interrupt.h> 79 #include <linux/pci.h> 80 #include <linux/slab.h> 81 #include <linux/vmalloc.h> 82 #include <linux/moduleparam.h> 83 #include <sound/core.h> 84 #include <sound/initval.h> 85 #include <sound/pcm.h> 86 #include <sound/ac97_codec.h> 87 #include <sound/info.h> 88 #include <sound/tlv.h> 89 #include <sound/emu10k1.h> 90 #include "p16v.h" 91 92 #define SET_CHANNEL 0 /* Testing channel outputs 0=Front, 1=Center/LFE, 2=Unknown, 3=Rear */ 93 #define PCM_FRONT_CHANNEL 0 94 #define PCM_REAR_CHANNEL 1 95 #define PCM_CENTER_LFE_CHANNEL 2 96 #define PCM_SIDE_CHANNEL 3 97 #define CONTROL_FRONT_CHANNEL 0 98 #define CONTROL_REAR_CHANNEL 3 99 #define CONTROL_CENTER_LFE_CHANNEL 1 100 #define CONTROL_SIDE_CHANNEL 2 101 102 /* Card IDs: 103 * Class 0401: 1102:0004 (rev 04) Subsystem: 1102:2002 -> Audigy2 ZS 7.1 Model:SB0350 104 * Class 0401: 1102:0004 (rev 04) Subsystem: 1102:1007 -> Audigy2 6.1 Model:SB0240 105 * Class 0401: 1102:0004 (rev 04) Subsystem: 1102:1002 -> Audigy2 Platinum Model:SB msb0240230009266 106 * Class 0401: 1102:0004 (rev 04) Subsystem: 1102:2007 -> Audigy4 Pro Model:SB0380 M1SB0380472001901E 107 * 108 */ 109 110 /* hardware definition */ 111 static const struct snd_pcm_hardware snd_p16v_playback_hw = { 112 .info = SNDRV_PCM_INFO_MMAP | 113 SNDRV_PCM_INFO_INTERLEAVED | 114 SNDRV_PCM_INFO_BLOCK_TRANSFER | 115 SNDRV_PCM_INFO_RESUME | 116 SNDRV_PCM_INFO_MMAP_VALID | 117 SNDRV_PCM_INFO_SYNC_START, 118 .formats = SNDRV_PCM_FMTBIT_S32_LE, /* Only supports 24-bit samples padded to 32 bits. */ 119 .rates = SNDRV_PCM_RATE_192000 | SNDRV_PCM_RATE_96000 | SNDRV_PCM_RATE_48000 | SNDRV_PCM_RATE_44100, 120 .rate_min = 44100, 121 .rate_max = 192000, 122 .channels_min = 8, 123 .channels_max = 8, 124 .buffer_bytes_max = ((65536 - 64) * 8), 125 .period_bytes_min = 64, 126 .period_bytes_max = (65536 - 64), 127 .periods_min = 2, 128 .periods_max = 8, 129 .fifo_size = 0, 130 };
