| 22 | * Module command line parameters: |
| 23 | * none so far |
| 24 | * |
| 25 | * Supported devices: |
| 26 | * /dev/dsp standard /dev/dsp device, (mostly) OSS compatible |
| 27 | * /dev/mixer standard /dev/mixer device, (mostly) OSS compatible |
| 28 | * /dev/midi simple MIDI UART interface, no ioctl |
| 29 | * |
| 30 | * Revision history |
| 31 | * 10.11.1998 0.1 Initial release (without any hardware) |
| 32 | * 22.03.1999 0.2 cinfo.blocks should be reset after GETxPTR ioctl. |
| 33 | * reported by Johan Maes <joma@telindus.be> |
| 34 | * return EAGAIN instead of EBUSY when O_NONBLOCK |
| 35 | * read/write cannot be executed |
| 36 | * 07.04.1999 0.3 implemented the following ioctl's: SOUND_PCM_READ_RATE, |
| 37 | * SOUND_PCM_READ_CHANNELS, SOUND_PCM_READ_BITS; |
| 38 | * Alpha fixes reported by Peter Jones <pjones@redhat.com> |
| 39 | * 15.06.1999 0.4 Fix bad allocation bug. |
| 40 | * Thanks to Deti Fliegl <fliegl@in.tum.de> |
| 41 | * 28.06.1999 0.5 Add pci_set_master |
| 42 | * 12.08.1999 0.6 Fix MIDI UART crashing the driver |
| 43 | * Changed mixer semantics from OSS documented |
| 44 | * behaviour to OSS "code behaviour". |
| 45 | * Recording might actually work now. |
| 46 | * The real DDMA controller address register is at PCI config |
| 47 | * 0x60, while the register at 0x18 is used as a placeholder |
| 48 | * register for BIOS address allocation. This register |
| 49 | * is supposed to be copied into 0x60, according |
| 50 | * to the Solo1 datasheet. When I do that, I can access |
| 51 | * the DDMA registers except the mask bit, which |
| 52 | * is stuck at 1. When I copy the contents of 0x18 +0x10 |
| 53 | * to the DDMA base register, everything seems to work. |
| 54 | * The fun part is that the Windows Solo1 driver doesn't |
| 55 | * seem to do these tricks. |
| 56 | * Bugs remaining: plops and clicks when starting/stopping playback |
| 57 | * 31.08.1999 0.7 add spin_lock_init |
| 58 | * replaced current->state = x with set_current_state(x) |
| 59 | * 03.09.1999 0.8 change read semantics for MIDI to match |
| 60 | * OSS more closely; remove possible wakeup race |
| 61 | * 07.10.1999 0.9 Fix initialization; complain if sequencer writes time out |
| 62 | * Revised resource grabbing for the FM synthesizer |
| 63 | * 28.10.1999 0.10 More waitqueue races fixed |
| 64 | * 09.12.1999 0.11 Work around stupid Alpha port issue (virt_to_bus(kmalloc(GFP_DMA)) > 16M) |
| 65 | * Disabling recording on Alpha |
| 66 | * 12.01.2000 0.12 Prevent some ioctl's from returning bad count values on underrun/overrun; |
| 67 | * Tim Janik's BSE (Bedevilled Sound Engine) found this |
| 68 | * Integrated (aka redid 8-)) APM support patch by Zach Brown |
| 69 | * 07.02.2000 0.13 Use pci_alloc_consistent and pci_register_driver |
| 70 | * 19.02.2000 0.14 Use pci_dma_supported to determine if recording should be disabled |
| 71 | * 13.03.2000 0.15 Reintroduce initialization of a couple of PCI config space registers |
| 72 | * 21.11.2000 0.16 Initialize dma buffers in poll, otherwise poll may return a bogus mask |
| 73 | * 12.12.2000 0.17 More dma buffer initializations, patch from |
| 74 | * Tjeerd Mulder <tjeerd.mulder@fujitsu-siemens.com> |
| 75 | * 31.01.2001 0.18 Register/Unregister gameport, original patch from |
| 76 | * Nathaniel Daw <daw@cs.cmu.edu> |
| 77 | * Fix SETTRIGGER non OSS API conformity |
| 78 | * 10.03.2001 provide abs function, prevent picking up a bogus kernel macro |
| 79 | * for abs. Bug report by Andrew Morton <andrewm@uow.edu.au> |
| 80 | * 15.05.2001 pci_enable_device moved, return values in probe cleaned |
| 81 | * up. Marcus Meissner <mm@caldera.de> |
| 82 | * 22.05.2001 0.19 more cleanups, changed PM to PCI 2.4 style, got rid |
| 83 | * of global list of devices, using pci device data. |
| 84 | * Marcus Meissner <mm@caldera.de> |
| 85 | * 03.01.2003 0.20 open_mode fixes from Georg Acher <acher@in.tum.de> |
