CVS commit: syssrc/sys/arch/arm
Module Name: syssrc
Committed By: thorpej
Date: Wed Aug 14 20:50:38 UTC 2002
Modified Files:
syssrc/sys/arch/arm/arm32: bus_dma.c
syssrc/sys/arch/arm/include: bus.h
Log Message:
* Add an ARM32_DMAMAP_COHERENT flag to indicate that a loaded DMA
map contains "coherent" (non-cached in ARM-land) mappings.
* Set ARM32_DMAMAP_COHERENT in the map at the start of a load operation,
and clear it in _bus_dmamap_load_buffer() if we encounter any cacheable
mappings.
* In _bus_dmamap_sync(), if the map is marked COHERENT, skip any cache
flushing.
