<title>Codec Interface</title>
<note>
<title>Suspended</title>
<para>This interface has been be suspended from the V4L2 API
implemented in Linux 2.6 until we have more experience with codec
device interfaces.</para>
</note>
<para>A V4L2 codec can compress, decompress, transform, or otherwise
convert video data from one format into another format, in memory.
Applications send data to be converted to the driver through a
&func-write; call, and receive the converted data through a
&func-read; call. For efficiency a driver may also support streaming
I/O.</para>
convert video data from one format into another format, in memory. Typically
such devices are memory-to-memory devices (i.e. devices with the
<constant>V4L2_CAP_VIDEO_M2M</constant> or <constant>V4L2_CAP_VIDEO_M2M_MPLANE</constant>
capability set).
</para>
<para>[to do]</para>
<para>A memory-to-memory video node acts just like a normal video node, but it
supports both output (sending frames from memory to the codec hardware) and
capture (receiving the processed frames from the codec hardware into memory)
stream I/O. An application will have to setup the stream
I/O for both sides and finally call &VIDIOC-STREAMON; for both capture and output
to start the codec.</para>
<para>Video compression codecs use the MPEG controls to setup their codec parameters
(note that the MPEG controls actually support many more codecs than just MPEG).
See <xref linkend="mpeg-controls"></xref>.</para>
<para>Memory-to-memory devices can often be used as a shared resource: you can
open the video node multiple times, each application setting up their own codec properties
that are local to the file handle, and each can use it independently from the others.
The driver will arbitrate access to the codec and reprogram it whenever another file
handler gets access. This is different from the usual video node behavior where the video properties
are global to the device (i.e. changing something through one file handle is visible
through another file handle).</para>

* ARM System MMU Architecture Implementation
ARM SoCs may contain an implementation of the ARM System Memory
Management Unit Architecture, which can be used to provide 1 or 2 stages
of address translation to bus masters external to the CPU.
The SMMU may also raise interrupts in response to various fault
conditions.
** System MMU required properties:
- compatible : Should be one of:
"arm,smmu-v1"
"arm,smmu-v2"
"arm,mmu-400"
"arm,mmu-500"
depending on the particular implementation and/or the
version of the architecture implemented.
- reg : Base address and size of the SMMU.
- #global-interrupts : The number of global interrupts exposed by the
device.
- interrupts : Interrupt list, with the first #global-irqs entries
corresponding to the global interrupts and any
following entries corresponding to context interrupts,
specified in order of their indexing by the SMMU.
For SMMUv2 implementations, there must be exactly one
interrupt per context bank. In the case of a single,
combined interrupt, it must be listed multiple times.
- mmu-masters : A list of phandles to device nodes representing bus
masters for which the SMMU can provide a translation
and their corresponding StreamIDs (see example below).
Each device node linked from this list must have a
"#stream-id-cells" property, indicating the number of
StreamIDs associated with it.
** System MMU optional properties:
- smmu-parent : When multiple SMMUs are chained together, this
property can be used to provide a phandle to the
parent SMMU (that is the next SMMU on the path going
from the mmu-masters towards memory) node for this
SMMU.
Example:
smmu {
compatible = "arm,smmu-v1";
reg = <0xba5e0000 0x10000>;
#global-interrupts = <2>;
interrupts = <0 32 4>,
<0 33 4>,
<0 34 4>, /* This is the first context interrupt */
<0 35 4>,
<0 36 4>,
<0 37 4>;
/*
* Two DMA controllers, the first with two StreamIDs (0xd01d
* and 0xd01e) and the second with only one (0xd11c).
*/
mmu-masters = <&dma0 0xd01d 0xd01e>,
<&dma1 0xd11c>;

This option enables the workaround for the 643719 Cortex-A9 (prior to
