Subject: [PATCH 2.4.22] meye driver updates
Date: Tue, 26 Aug 2003 16:10:56 +0200 [thread overview]
Message-ID: <20030826141056.GB9046@deep-space-9.dsnet> (raw)
Hi,
The attached patch updates the meye driver with some tiny changes:
* use SetPageReserved instead of mem_map_reserve, and remove
the wrapper.h dependency
* document the supported hardware.
Marcelo, please apply.
Stelian.

MJPEG hardware grabbing is supported via a private API (see below).
+Hardware supported:
+-------------------
+
+This driver supports the 'second' version of the MotionEye camera :)
+
+The first version was connected directly on the video bus of the Neomagic
+video card and is unsupported.
+
+The second one, made by Kawasaki Steel is fully supported by this
+driver (PCI vendor/device is 0x136b/0xff01)
+
+The third one, present in recent (more or less last year) Picturebooks
+(C1M* models), is not supported. The manufacturer has given the specs
+to the developers under a NDA (which allows the develoment of a GPL
+driver however), but things are not moving very fast (see
+http://r-engine.sourceforge.net/) (PCI vendor/device is 0x10cf/0x2011).
