From 66c2a6b0bc0b394d215768610d96f44cf97052ac Mon Sep 17 00:00:00 2001 From: Andy Walls Date: Mon, 8 Dec 2008 23:02:45 -0300 Subject: V4L/DVB (9801): cx18: Allow more than 63 capture buffers in rotation per stream 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.
