commit e9bfd63e863eb3a57e697e10e84c211a2ee4a7e5 Author: Stefan Reinauer reinauer@chromium.org Date: Fri May 4 15:37:18 2012 -0700
Add a tool to work on i915 hardware in user mode
This is the beginning of a tool that transforms the i9x5 code to user mode code. Consider this a very early stage although it does produce two programs. Requires spatch 1.0 or greater.
To try it out, assuming you have an up-to-date spatch, sh transform make make broken
Please don't fall to the temptation to auto-magicize this process. It's primitive for a reason. That said, suggestions welcome of course.
