No. That is repeating Kanoj's patch logic. What got into 2.4 kernel is slightly different. But like Stephen wondered, is there truly need to map the cards entirely into KERNEL space at all ? It is fairly trivial to create mmap() driver function to map them to user-space process. In display drivers I can understand a need to map parts (control registers, including command pipeline insert points) of the cards to kernel, but not all of the buffer spaces -- at least not all the time. /Matti Aarnio -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
