Now interrupt per period, instead of half period. * 0.13 * Use single trigger for multichannel. * 0.14 * Mic capture now works at fixed: S32_LE, 96000Hz, Stereo. * 0.15 * Force buffer_size / period_size == INTEGER. * 0.16 * Update p16v.c to work with changed alsa api. * 0.17 * Update p16v.c to work with changed alsa api. Removed boot_devs. * 0.18 * Merging with snd-emu10k1 driver. * 0.19 * One stereo channel at 24bit now works. * 0.20 * Added better register defines. * 0.21 * Integrated with snd-emu10k1 driver. * 0.22 * Removed #if 0 ... #endif * 0.23 * Implement different capture rates. * 0.24 * Implement different capture source channels. * e.g. When HD Capture source is set to SPDIF, * setting HD Capture channel to 0 captures from CDROM digital input. * setting HD Capture channel to 1 captures from SPDIF in. * 0.25 * Include capture buffer sizes. * * BUGS: * Some stability problems when unloading the snd-p16v kernel module. * -- * * TODO: * SPDIF out. * Find out how to change capture sample rates. E.g. To record SPDIF at 48000Hz. * Currently capture fixed at 48000Hz. * * -- * GENERAL INFO: * Model: SB0240 * P16V Chip: CA0151-DBS * Audigy 2 Chip: CA0102-IAT * AC97 Codec: STAC 9721 * ADC: Philips 1361T (Stereo 24bit) * DAC: CS4382-K (8-channel, 24bit, 192Khz) * * This code was initially based on code from ALSA's emu10k1x.c which is: * Copyright (c) by Francisco Moraes <[email protected]> */ #include <linux/delay.h> #include <linux/init.h> #include <linux/interrupt.h> #include <linux/pci.h> #include <linux/slab.h> #include <linux/vmalloc.h> #include <linux/moduleparam.h> #include <sound/core.h> #include <sound/initval.h> #include <sound/pcm.h> #include <sound/ac97_codec.h> #include <sound/info.h> #include <sound/tlv.h> #include <sound/emu10k1.h> #include "p16v.h" #define SET_CHANNEL … #define PCM_FRONT_CHANNEL … #define PCM_REAR_CHANNEL … #define PCM_CENTER_LFE_CHANNEL … #define PCM_SIDE_CHANNEL … #define CONTROL_FRONT_CHANNEL … #define CONTROL_REAR_CHANNEL … #define CONTROL_CENTER_LFE_CHANNEL … #define CONTROL_SIDE_CHANNEL … /* Card IDs: * Class 0401: 1102:0004 (rev 04) Subsystem: 1102:2002 -> Audigy2 ZS 7.1 Model:SB0350 * Class 0401: 1102:0004 (rev 04) Subsystem: 1102:1007 -> Audigy2 6.1 Model:SB0240 * Class 0401: 1102:0004 (rev 04) Subsystem: 1102:1002 -> Audigy2 Platinum Model:SB msb0240230009266 * Class 0401: 1102:0004 (rev 04) Subsystem: 1102:2007 -> Audigy4 Pro Model:SB0380 M1SB0380472001901E * */ /* hardware definition */ static const struct snd_pcm_hardware snd_p16v_playback_hw = …; static const struct snd_pcm_hardware snd_p16v_capture_hw = …; /* open_playback callback */ static int snd_p16v_pcm_open_playback_channel(struct snd_pcm_substream *substream, int channel_id) { … } /* open_capture callback */ static int snd_p16v_pcm_open_capture_channel(struct snd_pcm_substream *substream, int channel_id) { … } /* close callback */ static int snd_p16v_pcm_close_playback(struct snd_pcm_substream *substream) { … } /* close callback */ static int snd_p16v_pcm_close_capture(struct snd_pcm_substream *substream) { … } static int snd_p16v_pcm_open_playback_front(struct snd_pcm_substream *substream) { … } static int snd_p16v_pcm_open_capture(struct snd_pcm_substream *substream) { … } static int snd_p16v_pcm_ioctl_playback(struct snd_pcm_substream *substream, unsigned int cmd, void *arg) { … } /* prepare playback callback */ static int snd_p16v_pcm_prepare_playback(struct snd_pcm_substream *substream) { … } /* prepare capture callback */ static int snd_p16v_pcm_prepare_capture(struct snd_pcm_substream *substream) { … } static void snd_p16v_intr_enable(struct snd_emu10k1 *emu, unsigned int intrenb) { … } static void snd_p16v_intr_disable(struct snd_emu10k1 *emu, unsigned int intrenb) { … } static void snd_p16v_interrupt(struct snd_emu10k1 *emu) { … } /* trigger_playback callback */ static int snd_p16v_pcm_trigger_playback(struct snd_pcm_substream *substream, int cmd) { … } /* trigger_capture callback */ static int snd_p16v_pcm_trigger_capture(struct snd_pcm_substream *substream, int cmd) { … } /* pointer_playback callback */ static snd_pcm_uframes_t snd_p16v_pcm_pointer_playback(struct snd_pcm_substream *substream) { … } /* pointer_capture callback */ static snd_pcm_uframes_t snd_p16v_pcm_pointer_capture(struct snd_pcm_substream *substream) { … } /* operators */ static const struct snd_pcm_ops snd_p16v_playback_front_ops = …; static const struct snd_pcm_ops snd_p16v_capture_ops = …; int snd_p16v_pcm(struct snd_emu10k1 *emu, int device) { … } static int snd_p16v_volume_info(struct snd_kcontrol *kcontrol, struct snd_ctl_elem_info *uinfo) { … } static int snd_p16v_volume_get(struct snd_kcontrol *kcontrol, struct snd_ctl_elem_value *ucontrol) { … } static int snd_p16v_volume_put(struct snd_kcontrol *kcontrol, struct snd_ctl_elem_value *ucontrol) { … } static int snd_p16v_capture_source_info(struct snd_kcontrol *kcontrol, struct snd_ctl_elem_info *uinfo) { … } static int snd_p16v_capture_source_get(struct snd_kcontrol *kcontrol, struct snd_ctl_elem_value *ucontrol) { … } static int snd_p16v_capture_source_put(struct snd_kcontrol *kcontrol, struct snd_ctl_elem_value *ucontrol) { … } static int snd_p16v_capture_channel_info(struct snd_kcontrol *kcontrol, struct snd_ctl_elem_info *uinfo) { … } static int snd_p16v_capture_channel_get(struct snd_kcontrol *kcontrol, struct snd_ctl_elem_value *ucontrol) { … } static int snd_p16v_capture_channel_put(struct snd_kcontrol *kcontrol, struct snd_ctl_elem_value *ucontrol) { … } static const DECLARE_TLV_DB_SCALE(snd_p16v_db_scale1, -5175, 25, 1); #define P16V_VOL(xname,xreg,xhl) … static const struct snd_kcontrol_new p16v_mixer_controls[] = …; int snd_p16v_mixer(struct snd_emu10k1 *emu) { … } #ifdef CONFIG_PM_SLEEP #define NUM_CHS … int snd_p16v_alloc_pm_buffer(struct snd_emu10k1 *emu) { … } void snd_p16v_free_pm_buffer(struct snd_emu10k1 *emu) { … } void snd_p16v_suspend(struct snd_emu10k1 *emu) { … } void snd_p16v_resume(struct snd_emu10k1 *emu) { … } #endif
