RADEON_SETPARAM_FB_LOCATION

[Jon S. <jon...@ya...>]

/* 1.10: Clients tell the DRM where they think the framebuffer is 
 * located in the card's address space, via a new generic ioctl 
 * to set parameters
 */

Why is this needed? It looks like radeon_check_and_fixup_offset() and
friends use this to adjust all of the buffer addresses.

Why doesn't the client just ask where framebuffer is instead of picking
a location and then having the driver adjust the address?
