Dumb binary interfaces which allow root-only updates of the cache remapping registers. As mentioned in a previous patch, software using this interface needs to know about HW limits, and other programming considerations as the kernel interface does no checking for these things on the root-only interface. v1: Drop extra posting reads (Chris) Return negative values in the sysfs interfaces on errors (Chris) v2: Return -EINVAL for offset % 4 (Jesse) Move schizo userspace check out (Jesse) Cleaner sysfs item initializers (Daniel) Signed-off-by: Ben Widawsky <ben@bwidawsk.net> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> |
