 The kernel configures the translation tables so that translations made
 via TTBR0 (i.e. userspace mappings) have the top byte (bits 63:56) of
 the virtual address ignored by the translation hardware. This frees up
-this byte for application use, with the following caveats:
+this byte for application use.
 
-	(1) The kernel requires that all user addresses passed to EL1
-	    are tagged with tag 0x00. This means that any syscall
-	    parameters containing user virtual addresses *must* have
-	    their top byte cleared before trapping to the kernel.
 
-	(2) Non-zero tags are not preserved when delivering signals.
-	    This means that signal handlers in applications making use
-	    of tags cannot rely on the tag information for user virtual
-	    addresses being maintained for fields inside siginfo_t.
-	    One exception to this rule is for signals raised in response
-	    to watchpoint debug exceptions, where the tag information
-	    will be preserved.
+Passing tagged addresses to the kernel
+--------------------------------------
 
-	(3) Special care should be taken when using tagged pointers,
-	    since it is likely that C compilers will not hazard two
-	    virtual addresses differing only in the upper byte.
+All interpretation of userspace memory addresses by the kernel assumes
+an address tag of 0x00.
+
+This includes, but is not limited to, addresses found in:
+
+ - pointer arguments to system calls, including pointers in structures
+   passed to system calls,
+
+ - the stack pointer (sp), e.g. when interpreting it to deliver a
+   signal,
+
+ - the frame pointer (x29) and frame records, e.g. when interpreting
+   them to generate a backtrace or call graph.
+
+Using non-zero address tags in any of these locations may result in an
+error code being returned, a (fatal) signal being raised, or other modes
+of failure.
+
+For these reasons, passing non-zero address tags to the kernel via
+system calls is forbidden, and using a non-zero address tag for sp is
+strongly discouraged.
+
+Programs maintaining a frame pointer and frame records that use non-zero
+address tags may suffer impaired or inaccurate debug and profiling
+visibility.
+
+
+Preserving tags
+---------------
+
+Non-zero tags are not preserved when delivering signals. This means that
+signal handlers in applications making use of tags cannot rely on the
+tag information for user virtual addresses being maintained for fields
+inside siginfo_t. One exception to this rule is for signals raised in
+response to watchpoint debug exceptions, where the tag information will
+be preserved.
 
 The architecture prevents the use of a tagged PC, so the upper byte will
 be set to a sign-extension of bit 55 on exception return.
+
+
+Other considerations
+--------------------
+
+Special care should be taken when using tagged pointers, since it is
+likely that C compilers will not hazard two virtual addresses differing
+only in the upper byte.

+Howto use the configfs overlay interface.
+
+A device-tree configfs entry is created in /config/device-tree/overlays
+and and it is manipulated using standard file system I/O.
+Note that this is a debug level interface, for use by developers and
+not necessarily something accessed by normal users due to the
+security implications of having direct access to the kernel's device tree.
+
+* To create an overlay you mkdir the directory:
+
+	# mkdir /config/device-tree/overlays/foo
+
+* Either you echo the overlay firmware file to the path property file.
+
+	# echo foo.dtbo >/config/device-tree/overlays/foo/path
+
+* Or you cat the contents of the overlay to the dtbo file
+
+	# cat foo.dtbo >/config/device-tree/overlays/foo/dtbo
+
+The overlay file will be applied, and devices will be created/destroyed
+as required.
+
+To remove it simply rmdir the directory.
+
+	# rmdir /config/device-tree/overlays/foo
+
+The rationalle of the dual interface (firmware & direct copy) is that each is
+better suited to different use patterns. The firmware interface is what's
+intended to be used by hardware managers in the kernel, while the copy interface
+make sense for developers (since it avoids problems with namespaces).

+3. Quick Start
+==============
+
+You need a version 1.0 or later of v4l2-ctl, available from:
+	git://git.linuxtv.org/v4l-utils.git
+
+$ sudo modprobe bcm2835-v4l2
+
+Turn on the overlay:
+
+$ v4l2-ctl --overlay=1
+
+Turn off the overlay:
+
+$ v4l2-ctl --overlay=0
+
+Set the capture format for video:
+
+$ v4l2-ctl  --set-fmt-video=width=1920,height=1088,pixelformat=4
+
+(Note: 1088 not 1080).
+
+Capture:
+
+$ v4l2-ctl --stream-mmap=3 --stream-count=100 --stream-to=somefile.h264
+
+Stills capture:
+
+$ v4l2-ctl  --set-fmt-video=width=2592,height=1944,pixelformat=3
+$ v4l2-ctl --stream-mmap=3 --stream-count=1 --stream-to=somefile.jpg
