Bruce Evans dd87702a51 Allocate DMA bounce buffers only when requested by drivers. Only the ... fd and wt drivers need bounce buffers, so this normally saves 32K-1K of kernel memory. Keep track of which DMA channels are busy. isa_dmadone() must now be called when DMA has finished or been aborted. Panic for unallocated and too-small (required) bounce buffers. fd.c: There will be new warnings about isa_dmadone() not being called after DMA has been aborted. sound/dmabuf.c: isa_dmadone() needs more parameters than are available, so temporarily use a new interface isa_dmadone_nobounce() to avoid having to worry about panics for fake parameters. Untested.		1996-01-27 02:33:48 +00:00
