sys/i386/isa isa.c
Log:
Here is a patch to alleviate the current problem with the dma interface
and the sound driver which uses auto dma.
The dma interface functionality remains however it now checks
to see if a dma is operating in auto dma mode and if so it bypasses
the busy flag check . I have modified the sound driver 3.5 to
adjust for this new behavior and tested it under FreeBSD 3.0 -current
This patch also includes the new function isa_dmastop.
