From 94703235501e112e7496efe5bce32671e121d98f Mon Sep 17 00:00:00 2001 From: Andy Walls Date: Tue, 4 Nov 2008 22:49:14 -0500 Subject: cx18: Move DVB buffer transfer handling from irq handler to work_queue From: Andy Walls cx18: Move DVB buffer transfer handling from irq handler to work_queue thread. In order to properly lock the epu2cpu mailbox for driver to CX23418 commands, the DVB/TS buffer handling needs to be moved from the IRQ handler and IRQ context to a work queue. This work_queue implmentation is strikingly similar to the ivtv implementation - for better or worse.
