[Intel-gfx] [PATCH 0/5] gem-stress librarification + ctx test

[Ben Widawsky]

My motivation for these patches is to test HW context support. In doing
this I realized that all 3d state stuff is stuck in gem_stress. The 2nd
and 3rd patches pull gem_stress out into a library.

gem_stress does not appear at all threadsafe. To cheaply workaround this
(for now) deal with it by using fork/exec instead of multithreaded
programs.

An example of how to do this is with the context test I created. Patch 4
and 5 implement this. Patch 4 is a simple wrapper for libdrm calls,
patch 5 is the test itself. This won't compile for people unless they
use my libdrm, and the test won't be usable unless people take my
kernel. I plan to post those separately in the very near future. However
for those interested the branches are available from my freedesktop.org
repositories.
