From 39c3d488452ae206cfc8afda0db041ee55d01c3c Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Sat, 25 Dec 2010 07:44:33 -0300 Subject: [media] cpia, stradis: remove deprecated V4L1 drivers Nobody stepped in to convert these drivers to V4L2, so they are now removed from the kernel.

Right now a -polling grab-scheme is used. Maybe interrupt driven streaming will be -used for a asynchronous mmap interface in the next major release of the -driver. This might give a better frame rate. - ---------------------------------------------------------------------------- -THANKS (in no particular order): - -- Scott J.
