Is the zero-copy DMA feature of > st.c known to work OK with x86 highmem? It is _not_ known _not_ to work ;-) I.e., I have received neither any success nor any failure reports. I have not tested it because I don't have any machine with enough memory (and I have not hacked a kernel to use highmem with 512 MB of memory). I hope someone seeing this thread and using highmem with tape can comment on this subject. -- Kai - : send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
