2010-10-21V4L/DVB: videobuf: add queue argument to videobuf_waiton()Hans Verkuil1-1/+1
videobuf_waiton() must unlock and relock ext_lock if it has to wait. For that to happen it needs the videobuf_queue pointer. Don't attempt to unlock/relock q->ext_lock unless it was locked in the first place. vb->state has to be protected by a spinlock to be safe. This patch is based on code from Mauro Carvalho Chehab <mchehab@redhat.com>.

2010-05-19V4L/DVB: [v5,2/2] v4l: Add a mem-to-mem videobuf framework test devicePawel Osciak1-0/+1049
This is a virtual device driver for testing the memory-to-memory framework. This virtual device uses in-memory buffers for both its source and destination. It is capable of multi-instance, multi-buffer-per-transaction operation (via the mem2mem framework).
