X-Git-Tag: v2.6.31-rc1~297^2~308 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=87116159517ecf6b9cf62a136f2935a63833c485;p=pandora-kernel.git V4L/DVB (11616): cx18: Add a work queue for deferring empty buffer handoffs to the firmware This change defers sending all CX18_CPU_DE_SET_MDL commands, for a stream with an ongoing capture, by adding a work queue to handle sending such commands when needed. This prevents any sleeps, caused by notifying the firmware of new usable buffers, when a V4L2 application read() is being satisfied or when an incoming buffer is processed by the cx18-NN-in work queue thread.
