* Rearrange the speed mapping table and adjust the code so that the highest rate can actually be used. Previously we ended up rounding up slightly lower speeds and then losing because set_params couldn't set the mode back to the current one. * Allow 260 as a valid I/O address, since the SB1 can be jumpered to this. * Change the MPU-401 code so it can be attached as a separate device. (XXX Really, the SB code ought to just attach a subdevice itself.) * Do not attach an OPL on the SB1. Writing to the OPL registers at SB_base+0 on this card wedges my machine. (XXX Should we access it at 388 instead? The Creative web site claims that this board *does* have an OPL2, but I haven't played with this extensively.) * Allocate the SB DMA channels at open time, rather than attach time, so that a single DRQ can be used for multiple cards (if only one is in use at a given time). (XXX Let me tell you why this is a horrible hack. If the ISA DMA code tries to allocate a bounce buffer after boot time, it will generally fail, because there is no contiguous memory below 16MB and the code to allocate contiguous pages doesn't know how to move things around. Now, we shouldn't ever be using bounce buffers here, because we use isa_dmamem_alloc(). So we just turn off BUS_DMA_ALLOCNOW and we don't actually try to. That's cool, and it even works, but isa_dmamem_alloc() has the same problem. It just happens that we allocate the ring buffers at boot time, and whenever we reallocate them (due to the buffer size changing), we just deallocated the previous (contiguous) buffer, so we get lucky. This is absolutely disgusting and needs to be fixed.)

/*

|
* Software state, per SoundBlaster card.
|
|
* The soundblaster has multiple functionality, which we must demultiplex.
|
|
* One approach is to have one major device number for the soundblaster card,
|
|
* and use different minor numbers to indicate which hardware function
|
|
* we want. This would make for one large driver. Instead our approach
|
|
* is to partition the design into a set of drivers that share an underlying
|
|
* piece of hardware. Most things are hard to share, for example, the audio
|
|
* and midi ports. For audio, we might want to mix two processes' signals,
|
|
* and for midi we might want to merge streams (this is hard due to
|
|
* running status). Moreover, we should be able to re-use the high-level
|
|
* modules with other kinds of hardware. In this module, we only handle the
|
|
* most basic communications with the sb card.
