fvdl d88cf589cb A few ISA sound drivers like to share dma channels, and hence deferred ... isa_dmamap_create() calls to their open/close entrypoints. This worked with some luck, but broke on i386 when _bus_dmamap_create started to allocate bounce buffers upfront, since memory below 16M may well not be available when the sound devices is opened for the Nth time. To fix this, create a new simple interface, isa_drq_alloc/isa_drq_free, wrappers around already existing bitmask macros. These are expected to be used before an isa_dmamap_create call, and after an isa_dmamap_destroy call, respectively. For the sb and ad1848 drivers, they're deferred until open/close. All isa_dmamap_create calls can now use BUS_DMA_ALLOCNOW and be done at attach time.		2003-05-09 23:51:25 +00:00
