Wasn't there a patch submitted which suggested to add pci_dma_prep_*() calls in order to sync the cpu-driven changes back to the bus? I'm asking because I'm dealing with a driver that needs to reuse streaming pci maps.
Yes, basically this is what must happen.
If someone would code up a patch that includes the MIPS implementation, adds NOP implementations to every other asm/pci.h file and updates the Documentation/DMA-mapping.txt file appropriately, I'll probably just apply the patch and merge it upstream immediately.
I don't have time to work on this patch right now and I don't know how the MIPS part should be implemented so... - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
