That is what /dev/dac is for. By now (Q2 1998) * there are several MIDI to PCM (WAV) packages, one of them is timidity. * * Revision history * 04.06.1998 0.1 Initial release * Mixer stuff should be overhauled; especially optional AC97 mixer bits * should be detected. This results in strange behaviour of some mixer * settings, like master volume and mic. * 08.06.1998 0.2 First release using Alan Cox' soundcore instead of miscdevice * 03.08.1998 0.3 Do not include modversions.h * Now mixer behaviour can basically be selected between * "OSS documented" and "OSS actual" behaviour * 31.08.1998 0.4 Fix realplayer problems - dac.count issues * 27.10.1998 0.5 Fix joystick support * -- Oliver Neukum (c188@org.chemie.uni-muenchen.de) * 10.12.1998 0.6 Fix drain_dac trying to wait on not yet initialized DMA * 23.12.1998 0.7 Fix a few f_file & FMODE_ bugs * Don't wake up app until there are fragsize bytes to read/write * 06.01.1999 0.8 remove the silly SA_INTERRUPT flag. * hopefully killed the egcs section type conflict * 12.03.1999 0.9 cinfo.blocks should be reset after GETxPTR ioctl. * reported by Johan Maes <joma@telindus.be> * 22.03.1999 0.10 return EAGAIN instead of EBUSY when O_NONBLOCK * read/write cannot be executed * 07.04.1999 0.11 implemented the following ioctl's: SOUND_PCM_READ_RATE, * SOUND_PCM_READ_CHANNELS, SOUND_PCM_READ_BITS; * Alpha fixes reported by Peter Jones <pjones@redhat.com> * Another Alpha fix (wait_src_ready in init routine) * reported by "Ivan N. Kokshaysky" <ink@jurassic.park.msu.ru> * Note: joystick address handling might still be wrong on archs * other than i386 * 15.06.1999 0.12 Fix bad allocation bug. * Thanks to Deti Fliegl <fliegl@in.tum.de> * 28.06.1999 0.13 Add pci_set_master * 03.08.1999 0.14 adapt to Linus' new __setup/__initcall * added kernel command line option "es1371=joystickaddr" * removed CONFIG_SOUND_ES1371_JOYPORT_BOOT kludge * 10.08.1999 0.15 (Re)added S/PDIF module option for cards revision >= 4. * Initial version by Dave Platt <dplatt@snulbug.mtview.ca.us>. * module_init/__setup fixes * 08.16.1999 0.16 Joe Cotellese <joec@ensoniq.com> * Added detection for ES1371 revision ID so that we can * detect the ES1373 and later parts. * added AC97 #defines for readability * added a /proc file system for dumping hardware state * updated SRC and CODEC w/r functions to accommodate bugs * in some versions of the ES137x chips. * 31.08.1999 0.17 add spin_lock_init * replaced current->state = x with set_current_state(x) * 03.09.1999 0.18 change read semantics for MIDI to match * OSS more closely; remove possible wakeup race * 21.10.1999 0.19 Round sampling rates, requested by * Kasamatsu Kenichi <t29w0267@ip.media.kyoto-u.ac.jp> * 27.10.1999 0.20 Added SigmaTel 3D enhancement string * Codec ID printing changes * 28.10.1999 0.21 More waitqueue races fixed * Joe Cotellese <joec@ensoniq.com> * Changed PCI detection routine so we can more easily * detect ES137x chip and derivatives. * 05.01.2000 0.22 Should now work with rev7 boards; patch by * Eric Lemar, elemar@cs.washington.edu * 08.01.2000 0.23 Prevent some ioctl's from returning bad count values on underrun/overrun; * Tim Janik's BSE (Bedevilled Sound Engine) found this * 07.02.2000 0.24 Use pci_alloc_consistent and pci_register_driver * 07.02.2000 0.25 Use ac97_codec * 01.03.2000 0.26 SPDIF patch by Mikael Bouillot <mikael.bouillot@bigfoot.com> * Use pci_module_init * 21.11.2000 0.27 Initialize dma buffers in poll, otherwise poll may return a bogus mask * 12.12.2000 0.28 More dma buffer initializations, patch from * Tjeerd Mulder <tjeerd.mulder@fujitsu-siemens.com> * 05.01.2001 0.29 Hopefully updates will not be required anymore when Creative bumps * the CT5880 revision. * suggested by Stephan M�ller <smueller@chronox.de> * 31.01.2001 0.30 Register/Unregister gameport * Fix SETTRIGGER non OSS API conformity * 14.07.2001 0.31 Add list of laptops needing amplifier control * 03.01.2003 0.32 open_mode fixes from Georg Acher <acher@in.tum.de> */ /*****************************************************************************/ #include <linux/interrupt.h> #include <linux/module.h> #include <linux/string.h> #include <linux/ioport.h> #include <linux/sched.h> #include <linux/delay.h> #include <linux/sound.h> #include <linux/slab.h> #include <linux/soundcard.h> #include <linux/pci.h> #include <linux/init.h> #include <linux/poll.h> #include <linux/bitops.h> #include <linux/proc_fs.h> #include <linux/spinlock.h> #include <linux/smp_lock.h> #include <linux/ac97_codec.h> #include <linux/gameport.h> #include <linux/wait.h> #include <linux/dma-mapping.h> #include <asm/io.h> #include <asm/page.h> #include <asm/uaccess.h> #if defined(CONFIG_GAMEPORT) || (defined(MODULE) && defined(CONFIG_GAMEPORT_MODULE)) #define SUPPORT_JOYSTICK #endif /* --------------------------------------------------------------------- */ #undef OSS_DOCUMENTED_MIXER_SEMANTICS #define ES1371_DEBUG #define DBG(x) {} /*#define DBG(x) {x}*/ /* --------------------------------------------------------------------- */ #ifndef PCI_VENDOR_ID_ENSONIQ #define PCI_VENDOR_ID_ENSONIQ 0x1274 #endif #ifndef PCI_VENDOR_ID_ECTIVA #define PCI_VENDOR_ID_ECTIVA 0x1102 #endif #ifndef PCI_DEVICE_ID_ENSONIQ_ES1371 #define PCI_DEVICE_ID_ENSONIQ_ES1371 0x1371 #endif #ifndef PCI_DEVICE_ID_ENSONIQ_CT5880 #define PCI_DEVICE_ID_ENSONIQ_CT5880 0x5880 #endif #ifndef PCI_DEVICE_ID_ECTIVA_EV1938 #define PCI_DEVICE_ID_ECTIVA_EV1938 0x8938 #endif /* ES1371 chip ID */ /* This is a little confusing because all ES1371 compatible chips have the same DEVICE_ID, the only thing differentiating them is the REV_ID field.
