From 9d7056dacd1d54274a25c153eb298ccdf6232b54 Mon Sep 17 00:00:00 2001 From: netchild Date: Fri, 10 Jun 2011 07:54:38 +0000 Subject: [PATCH] MFC r221423, r221424, r221426, r221428, r221434: This is v4l2 support for the linuxulator. This allows to access FreeBSD native devices which support the v4l2 API from processes running within the linuxulator, e.g. skype or flash can access the multimedia/pwcbsd or multimedia/webcamd supplied drivers. MFC r221425: Fix typo in comment, improve comment. MFC tested by: nox git-svn-id: svn://svn.freebsd.org/base/stable/8@222914 ccf9f872-aa2e-dd11-9fc8-001c23d0bc1f --- sys/compat/linux/linux_ioctl.c | 310 ++++++ sys/compat/linux/linux_ioctl.h | 97 ++
