[PATCH 4/8] modesetting: Move dumb_bo into its own source files.

Kenneth Graunke kenneth at whitecape.org
Tue Dec 9 16:55:27 PST 2014


Eventually, drmmode_display will be able to use GBM for handling
buffers, and won't need dumb_bo.  Keeping the display related logic
and buffer object abstraction in separate files seems a bit tidier.
