For the VCE buffer range checks that fixed a lockup I experienced while working on the userspace driver (VCE writing over the end of a buffer into an shader, GPU then trying to execute the messed up shader code...). Apart from that VCE is a new feature for 3.15 so we can't really break it compared to 3.14. I can't judge on the I2C mutex since that was Alex suggestion and I'm not sure how invasive and/or necessary this is. Regards, Christian. > > Dave.
