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>
