| H A D | isa_dma.c | diff 233675 Thu Mar 29 17:04:53 MDT 2012 jhb Restore proper use of bounce buffers for ISA DMA. When locking was added, the call to pmap_kextract() was moved up, and as a result the code never updated the physical address to use for DMA if a bounce buffer was used. Restore the earlier location of pmap_kextract() so it takes bounce buffers into account. Tested by: kargl MFC after: 1 week |
