| H A D | busdma_bounce.c | diff 137965 Sun Nov 21 02:43:28 MST 2004 scottl MFC amd64: 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. |
