<title>Render nodes</title>
<para>
DRM core provides multiple character-devices for user-space to use.
Depending on which device is opened, user-space can perform a different
set of operations (mainly ioctls). The primary node is always created
and called <term>card&lt;num&gt;</term>. Additionally, a currently
unused control node, called <term>controlD&lt;num&gt;</term> is also
created. The primary node provides all legacy operations and
historically was the only interface used by userspace. With KMS, the
control node was introduced. However, the planned KMS control interface
has never been written and so the control node stays unused to date.
</para>
<para>
With the increased use of offscreen renderers and GPGPU applications,
clients no longer require running compositors or graphics servers to
make use of a GPU. But the DRM API required unprivileged clients to
authenticate to a DRM-Master prior to getting GPU access. To avoid this
step and to grant clients GPU access without authenticating, render
nodes were introduced. Render nodes solely serve render clients, that
is, no modesetting or privileged ioctls can be issued on render nodes.
Only non-global rendering commands are allowed. If a driver supports
render nodes, it must advertise it via the <term>DRIVER_RENDER</term>
DRM driver capability. If not supported, the primary node must be used
for render clients together with the legacy drmAuth authentication
procedure.
</para>
<para>
If a driver advertises render node support, DRM core will create a
separate render node called <term>renderD&lt;num&gt;</term>. There will
be one render node per device. No ioctls except PRIME-related ioctls
will be allowed on this node. Especially <term>GEM_OPEN</term> will be
explicitly prohibited. Render nodes are designed to avoid the
buffer-leaks, which occur if clients guess the flink names or mmap
offsets on the legacy interface. Additionally to this basic interface,
drivers must mark their driver-dependent render-only ioctls as
<term>DRM_RENDER_ALLOW</term> so render clients can use them. Driver
authors must be careful not to allow any privileged ioctls on render
nodes.
</para>
<para>
With render nodes, user-space can now control access to the render node
via basic file-system access-modes. A running graphics server which
authenticates clients on the privileged primary/legacy node is no longer
required. Instead, a client can open the render node and is immediately
granted GPU access. Communication between clients (or servers) is done
via PRIME. FLINK from render node to legacy node is not supported. New
clients must not use the insecure FLINK interface.
</para>
<para>
Besides dropping all modeset/global ioctls, render nodes also drop the
DRM-Master concept. There is no reason to associate render clients with
a DRM-Master as they are independent of any graphics server. Besides,
they must work without any running master, anyway.
Drivers must be able to run without a master object if they support
render nodes. If, on the other hand, a driver requires shared state
between clients which is visible to user-space and accessible beyond
open-file boundaries, they cannot support render nodes.

The luminance data occupies the first plane. The Y plane has one byte per pixel.
In the second plane there is chrominance data with alternating chroma samples.
The CbCr plane is the same width and height, in bytes, as the Y plane.
Each CbCr pair belongs to four pixels. For example,
Cb<subscript>0</subscript>/Cr<subscript>0</subscript> belongs to
Y'<subscript>00</subscript>, Y'<subscript>01</subscript>,
Y'<subscript>10</subscript>, Y'<subscript>11</subscript>.
<constant>V4L2_PIX_FMT_NV61M</constant> is the same as <constant>V4L2_PIX_FMT_NV16M</constant>
