From 0f973f27888e4664b253ab2cf69c67c2eb80ab1b Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Mon, 26 Jan 2009 17:10:45 -0800 Subject: drm/i915: add fence register management to execbuf Adds code to set up fence registers at execbuf time on pre-965 chips as necessary. Also fixes up a few bugs in the pre-965 tile register support (get_order != ffs). The number of fences available to the kernel defaults to the hw limit minus 3 (for legacy X front/back/depth), but a new parameter allows userspace to override that as needed.

This fixes potential fault at fault time if the object was unreferenced while the mapping still existed. Now, while the mmap_offset only lives for the lifetime of the object, the object also stays alive while a vma exists that needs it.
