scottl 2004-11-21 04:15:26 UTC FreeBSD src repository Modified files: sys/amd64/amd64 busdma_machdep.c Log: Consolidate all of the bounce tests into the BUS_DMA_COULD_BOUNCE flag. Allocate the bounce zone at either tag creation or map creation to help avoid null-pointer derefs later on. Track total pages per zone so that each zone can get a minimum allocation at tag creation time instead of being defeated by mis-behaving tags that suck up the max amount. Revision Changes Path 1.62 +45 -29 src/sys/amd64/amd64/busdma_machdep.c
