Hi Chris, have you updated this patch? I think this patch may be obsolete, as these patches http://lists.freedesktop.org/archives/intel-gfx/2011-March/009583.html do the same and much more. It is not clear yet how to prevent users from accidentally using these functions which will make the

This fails on the Macbook for example, and Jesse reported a failure after unloading and reloading the i915.ko module on a HP system. It looked promising distinguishing several of the ghost LVDS, but with even a single false positive, it cannot replace the quirk table. Signed-off-by: Chris Wilson

--- Here's an idea for an SNB performance improvement from the specs. It says that on GT2 you should be able to use 80 threads if "WIZ Hashing Disable in GT_MODE register enabled". On my system (supposedly GT2), that bit (bit 6 of 0x20d0) is unset. In testing, with intel_reg_write 0x20d0 0x0040
