Improved on stuttering wave playback. Added MIDI UART support. * 0.3 Fixed mixer routing bug, added APS, joystick support. * 0.4 Added rear-channel, SPDIF support. * 0.5 Source cleanup, SMP fixes, multiopen support, 64 bit arch fixes, * moved bh's to tasklets, moved to the new PCI driver initialization style. * 0.6 Make use of pci_alloc_consistent, improve compatibility layer for 2.2 kernels, * code reorganization and cleanup. * 0.7 Support for the Emu-APS. Bug fixes for voice cache setup, mmaped sound + poll(). * Support for setting external TRAM size. * 0.8 Make use of the kernel ac97 interface. Support for a dsp patch manager. * 0.9 Re-enables rear speakers volume controls * 0.10 Initializes rear speaker volume. * Dynamic patch storage allocation. * New private ioctls to change control gpr values. * Enable volume control interrupts. * By default enable dsp routes to digital out. * 0.11 Fixed fx / 4 problem. * 0.12 Implemented mmaped for recording. * Fixed bug: not unreserving mmaped buffer pages. * IRQ handler cleanup. * 0.13 Fixed problem with dsp1 * Simplified dsp patch writing (inside the driver) * Fixed several bugs found by the Stanford tools * 0.14 New control gpr to oss mixer mapping feature (Chris Purnell) * Added AC3 Passthrough Support (Juha Yrjola) * Added Support for 5.1 cards (digital out and the third analog out) * 0.15 Added Sequencer Support (Daniel Mack) * Support for multichannel pcm playback (Eduard Hasenleithner) * 0.16 Mixer improvements, added old treble/bass support (Daniel Bertrand) * Small code format cleanup. * Deadlock bug fix for emu10k1_volxxx_irqhandler(). * 0.17 Fix for mixer SOUND_MIXER_INFO ioctl. * Fix for HIGHMEM machines (emu10k1 can only do 31 bit bus master) * midi poll initial implementation. * Small mixer fixes/cleanups. * Improved support for 5.1 cards. * 0.18 Fix for possible leak in pci_alloc_consistent() * Cleaned up poll() functions (audio and midi). Don't start input. * Restrict DMA pages used to 512Mib range. * New AC97_BOOST mixer ioctl. * 0.19 Real fix for kernel with highmem support (cast dma_handle to u32). * Fix recording buffering parameters calculation. * Use unsigned long for variables in bit ops. * 0.20 Fixed recording startup * Fixed timer rate setting (it's a 16-bit register) *********************************************************************/ /* These are only included once per module */ #include #include #include #include #include #include #include "hwaccess.h" #include "8010.h" #include "efxmgr.h" #include "cardwo.h" #include "cardwi.h" #include "cardmo.h" #include "cardmi.h" #include "recmgr.h" #include "ecard.h" #ifdef EMU10K1_SEQUENCER #define MIDI_SYNTH_NAME "EMU10K1 MIDI" #define MIDI_SYNTH_CAPS SYNTH_CAP_INPUT #include "../sound_config.h" #include "../midi_synth.h" /* this should be in dev_table.h */ #define SNDCARD_EMU10K1 46 #endif #define DRIVER_VERSION "0.20" /* the emu10k1 _seems_ to only supports 29 bit (512MiB) bit bus master */ #define EMU10K1_DMA_MASK 0x1fffffff /* DMA buffer mask for pci_alloc_consist */ #ifndef PCI_VENDOR_ID_CREATIVE #define PCI_VENDOR_ID_CREATIVE 0x1102 #endif #ifndef PCI_DEVICE_ID_CREATIVE_EMU10K1 #define PCI_DEVICE_ID_CREATIVE_EMU10K1 0x0002 #endif #define EMU_APS_SUBID 0x40011102 enum { EMU10K1 = 0, }; static char *card_names[] __devinitdata = { "EMU10K1", }; static struct pci_device_id emu10k1_pci_tbl[] = { {PCI_VENDOR_ID_CREATIVE, PCI_DEVICE_ID_CREATIVE_EMU10K1, PCI_ANY_ID, PCI_ANY_ID, 0, 0, EMU10K1}, {0,} }; MODULE_DEVICE_TABLE(pci, emu10k1_pci_tbl); /* Global var instantiation */ LIST_HEAD(emu10k1_devs); extern struct file_operations emu10k1_audio_fops; extern struct file_operations emu10k1_mixer_fops; extern struct file_operations emu10k1_midi_fops; #ifdef EMU10K1_SEQUENCER static struct midi_operations emu10k1_midi_operations; #endif extern void emu10k1_interrupt(int, void *, struct pt_regs *s); static int __devinit emu10k1_audio_init(struct emu10k1_card *card) { card->audio_dev = register_sound_dsp(&emu10k1_audio_fops, -1); if (card->audio_dev < 0) { printk(KERN_ERR "emu10k1: cannot register first audio device!\n"); goto err_dev; } card->audio_dev1 = register_sound_dsp(&emu10k1_audio_fops, -1); if (card->audio_dev1 < 0) { printk(KERN_ERR "emu10k1: cannot register second audio device!\n"); goto err_dev1; } /* Assign default playback voice parameters */ card->mchannel_fx = 8; /* mono voice */ card->waveout.send_a[0] = 0xff; card->waveout.send_b[0] = 0xff; card->waveout.send_c[0] = 0x00; card->waveout.send_d[0] = 0x00; card->waveout.send_routing[0] = 0x3210; /* stereo voice */ /* left */ card->waveout.send_a[1] = 0xff; card->waveout.send_b[1] = 0x00; card->waveout.send_c[1] = 0x00; card->waveout.send_d[1] = 0x00; card->waveout.send_routing[1] = 0x3210; /* right */ card->waveout.send_a[2] = 0x00; card->waveout.send_b[2] = 0xff; card->waveout.send_c[2] = 0x00; card->waveout.send_d[2] = 0x00; card->waveout.send_routing[2] = 0x3210; /* Assign default recording parameters */ /* FIXME */ if (card->is_aps) card->wavein.recsrc = WAVERECORD_FX; else card->wavein.recsrc = WAVERECORD_AC97; card->wavein.fxwc = 0x0003; return 0; err_dev1: unregister_sound_dsp(card->audio_dev); err_dev: return -ENODEV; } static void __devinit emu10k1_audio_cleanup(struct emu10k1_card *card) { unregister_sound_dsp(card->audio_dev1); unregister_sound_dsp(card->audio_dev); } static int __devinit emu10k1_mixer_init(struct emu10k1_card *card) { char s[32]; struct ac97_codec *codec = ac97_alloc_codec(); if(codec == NULL) { printk(KERN_ERR "emu10k1: cannot allocate mixer\n"); return -EIO; } card->ac97 = codec; #warning "Initialisation order race.
