From b358f380079ca3db20d7409c3d39c2f5e80f871c Mon Sep 17 00:00:00 2001 From: Andy Walls Date: Mon, 8 Dec 2008 21:02:45 -0500 Subject: cx18: Allow more than 63 capture buffers in rotation per stream From: Andy Walls cx18: Allow more than 63 capture buffers in rotation per stream. Implement q_busy to hold buffers the firmware has for use. q_free holds truly unused buffers in a pool. New buffers are given to the firmware as soon as the firmware returns one, if there are any to give to the firmware.
