commit 574ab948af15c8deaf5afa11bd79b2ea2d9c202d Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Wed Jan 7 14:08:05 2015 +0000 sna: Add mmap(wc) handling to has_coherent_ptr assertion Extend the debuging sanity checks to also cover WC mappings. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Easiest w/a is not to enable the debugging assertions, or just use the git version. (Actually, fingers crossed that is the right bug!) |
