However the hw interfaces for aux ch are different enough that the code to translate from mode, address, bytes to actual hw interfaces isn't generic, so move that code into the Intel driver.

Instead of snooping the command stream this allows finer grained tracking of which areas have changed. The primary user for this functionality is virtual hardware like the vmware svga device, but also Xen hardware likes to be notify. There is also real hardware like DisplayLink and DisplayPort that might take advantage of this ioctl.

This is typically when all evictable buffers are evicted due to 1) vt switch 2) master switch 3) suspend / resume. In the multi-master case, on master switch the new master takes the previously active master lock in write mode, and then evicts all buffers. Any clients to previous masters will then block on that lock when trying to validate a buffer. fbdev also acts as a virtual master wrt this.

The ioctl takes an fb ID and a ctrc ID and flips the crtc to the given fb at the next vblank. The ioctl returns immediately but the flip doesn't happen until after any rendering that's currently queued up against the new framebuffer is done. After submitting a page flip, any execbuffer involving the old front buffer will block until the flip is completed. Optionally, a vblank event can be generated when the swap eventually happens.

Since pixclock is actually unsigned, the value -1 would be interpreted as 4294967295 picoseconds (i.e., about 4 milliseconds) by register_framebuffer() and userspace programs. This patch allows X.org's fbdev driver to work.

AFAIK this only affects running X under Xen; without this patch you get lots of coloured blobs on the screen, or maybe a complete lockup. Or anything really. But that still depends on lots of out-of-tree stuff, so I don't think there are any consequences for anyone else. But it is wrong in principle.
