Disclosure
----------
@ -39,6 +42,32 @@ disclosure is from immediate (esp. if it's already publicly known)
to a few weeks. As a basic default policy, we expect report date to
disclosure date to be on the order of 7 days.
Coordination
------------
Fixes for sensitive bugs, such as those that might lead to privilege
escalations, may need to be coordinated with the private
<linux-distros@vs.openwall.org> mailing list so that distribution vendors
are well prepared to issue a fixed kernel upon public disclosure of the
upstream fix. Distros will need some time to test the proposed patch and
will generally request at least a few days of embargo, and vendor update
publication prefers to happen Tuesday through Thursday. When appropriate,
the security team can assist with this coordination, or the reporter can
include linux-distros from the start. In this case, remember to prefix
the email Subject line with "[vs]" as described in the linux-distros wiki:
<http://oss-security.openwall.org/wiki/mailing-lists/distros#how-to-use-the-lists>
CVE assignment
--------------
The security team does not normally assign CVEs, nor do we require them
for reports or fixes, as this can needlessly complicate the process and
may delay the bug handling. If a reporter wishes to have a CVE identifier
assigned ahead of public disclosure, they will need to contact the private
linux-distros list, described above. When such a CVE identifier is known
before a patch is provided, it is desirable to mention it in the commit
message, though.

Parallel to LVDS Encoder
------------------------
This binding supports the parallel to LVDS encoders that don't require any
configuration.
LVDS is a physical layer specification defined in ANSI/TIA/EIA-644-A. Multiple
incompatible data link layers have been used over time to transmit image data
to LVDS panels. This binding targets devices compatible with the following
specifications only.
[JEIDA] "Digital Interface Standards for Monitor", JEIDA-59-1999, February
1999 (Version 1.0), Japan Electronic Industry Development Association (JEIDA)

Semiconductor
[VESA] "VESA Notebook Panel Standard", October 2007 (Version 1.0), Video
Electronics Standards Association (VESA)
Those devices have been marketed under the FPD-Link and FlatLink brand names
among others.
Required properties:
- compatible: Must be "lvds-encoder"
Required nodes:
This device has two video ports. Their connections are modeled using the OF
graph bindings specified in Documentation/devicetree/bindings/graph.txt.
- Video port 0 for parallel input
- Video port 1 for LVDS output

Drivers for the second video output of the GE B850v3:
STDP4028-ge-b850v3-fw bridges (LVDS-DP)
STDP2690-ge-b850v3-fw bridges (DP-DP++)
The video processing pipeline on the second output on the GE B850v3:
Host -> LVDS|--(STDP4028)--|DP -> DP|--(STDP2690)--|DP++ -> Video output
Each bridge has a dedicated flash containing firmware for supporting the custom
design. The result is that, in this design, neither the STDP4028 nor the
STDP2690 behave as the stock bridges would. The compatible strings include the
suffix "-ge-b850v3-fw" to make it clear that the driver is for the bridges with
the firmware specific for the GE B850v3.
The hardware do not provide control over the video processing pipeline, as the
two bridges behaves as a single one. The only interfaces exposed by the
hardware are EDID, HPD, and interrupts.

* DOT: http://graphviz.org/pdf/dotguide.pdf
* Graphviz: http://www.graphviz.org/content/dot-language
A simple example (:ref:`hello_dot_file`)::
.. kernel-figure:: hello.dot
:alt: hello world
DOT's hello world example
.. _hello_dot_file:
.. kernel-figure:: hello.dot
:alt: hello world
DOT's hello world example
Embed *render* markups (or languages) like Graphviz's **DOT** is provided by the
``kernel-render`` directives.::
.. kernel-render:: DOT
:alt: foobar digraph
:caption: Embedded **DOT** (Graphviz) code
digraph foo {
"bar" -> "baz";
}
How this will be rendered depends on the installed tools. If Graphviz is
installed, you will see an vector image. If not the raw markup is inserted as
*literal-block* (:ref:`hello_dot_render`).
.. _hello_dot_render:
.. kernel-render:: DOT
:alt: foobar digraph
:caption: Embedded **DOT** (Graphviz) code
digraph foo {
"bar" -> "baz";
}
The *render* directive has all the options known from the *figure* directive,
plus option ``caption``. If ``caption`` has a value, a *figure* node is
inserted. If not, a *image* node is inserted. A ``caption`` is also needed, if
you want to refer it (:ref:`hello_svg_render`).

Open/Close, File Operations and IOCTLs
======================================
Open and Close
--------------
Open and close handlers. None of those methods are mandatory::
int (*firstopen) (struct drm_device *);
void (*lastclose) (struct drm_device *);
int (*open) (struct drm_device *, struct drm_file *);
void (*preclose) (struct drm_device *, struct drm_file *);
void (*postclose) (struct drm_device *, struct drm_file *);
The firstopen method is called by the DRM core for legacy UMS (User Mode
Setting) drivers only when an application opens a device that has no
other opened file handle. UMS drivers can implement it to acquire device
resources. KMS drivers can't use the method and must acquire resources
in the load method instead.
Similarly the lastclose method is called when the last application
holding a file handle opened on the device closes it, for both UMS and
KMS drivers. Additionally, the method is also called at module unload
time or, for hot-pluggable devices, when the device is unplugged. The
firstopen and lastclose calls can thus be unbalanced.
The open method is called every time the device is opened by an
application. Drivers can allocate per-file private data in this method
and store them in the struct :c:type:`struct drm_file
<drm_file>` driver_priv field. Note that the open method is
called before firstopen.
The close operation is split into preclose and postclose methods.
Drivers must stop and cleanup all per-file operations in the preclose
method. For instance pending vertical blanking and page flip events must
be cancelled. No per-file operation is allowed on the file handle after
returning from the preclose method.
Finally the postclose method is called as the last step of the close
operation, right before calling the lastclose method if no other open
file handle exists for the device. Drivers that have allocated per-file
private data in the open method should free it here.
The lastclose method should restore CRTC and plane properties to default
value, so that a subsequent open of the device will not inherit state
from the previous user. It can also be used to execute delayed power
switching state changes, e.g. in conjunction with the :ref:`vga_switcheroo`
infrastructure. Beyond that KMS drivers should not do any
further cleanup. Only legacy UMS drivers might need to clean up device
state so that the vga console or an independent fbdev driver could take
over.

The basic object structure KMS presents to userspace is fairly simple.
Framebuffers (represented by :c:type:`struct drm_framebuffer <drm_framebuffer>`,
see `Frame Buffer Abstraction`_) feed into planes. One or more (or even no)
planes feed their pixel data into a CRTC (represented by :c:type:`struct
drm_crtc <drm_crtc>`, see `CRTC Abstraction`_) for blending. The precise
blending step is explained in more detail in `Plane Composition Properties`_ and
related chapters.
For the output routing the first step is encoders (represented by
:c:type:`struct drm_encoder <drm_encoder>`, see `Encoder Abstraction`_). Those
are really just internal artifacts of the helper libraries used to implement KMS
drivers. Besides that they make it unecessarily more complicated for userspace
to figure out which connections between a CRTC and a connector are possible, and
what kind of cloning is supported, they serve no purpose in the userspace API.
Unfortunately encoders have been exposed to userspace, hence can't remove them
at this point. Futhermore the exposed restrictions are often wrongly set by
drivers, and in many cases not powerful enough to express the real restrictions.
A CRTC can be connected to multiple encoders, and for an active CRTC there must
be at least one encoder.
The final, and real, endpoint in the display chain is the connector (represented
by :c:type:`struct drm_connector <drm_connector>`, see `Connector
Abstraction`_). Connectors can have different possible encoders, but the kernel
driver selects which encoder to use for each connector. The use case is DVI,
which could switch between an analog and a digital encoder. Encoders can also
drive multiple different connectors. There is exactly one active connector for
every active encoder.
Internally the output pipeline is a bit more complex and matches today's
hardware more closely:
.. kernel-render:: DOT
:alt: KMS Output Pipeline

label="Outputs"
"drm_encoder A" -> "drm_connector A";
"drm_bridge B" -> "drm_connector B";
"drm_bridge C2" -> "drm_connector C";
"drm_panel"
}
}
Internally two additional helper objects come into play. First, to be able to
share code for encoders (sometimes on the same SoC, sometimes off-chip) one or
more :ref:`drm_bridges` (represented by :c:type:`struct drm_bridge
<drm_bridge>`) can be linked to an encoder. This link is static and cannot be
changed, which means the cross-bar (if there is any) needs to be mapped between
the CRTC and any encoders. Often for drivers with bridges there's no code left
at the encoder level. Atomic drivers can leave out all the encoder callbacks to
essentially only leave a dummy routing object behind, which is needed for
backwards compatibility since encoders are exposed to userspace.
The second object is for panels, represented by :c:type:`struct drm_panel
<drm_panel>`, see :ref:`drm_panel_helper`. Panels do not have a fixed binding
point, but are generally linked to the driver private structure that embeds
:c:type:`struct drm_connector <drm_connector>`.
Note that currently the bridge chaining and interactions with connectors and
panels are still in-flux and not really fully sorted out yet.

The base structure for all KMS objects is :c:type:`struct drm_mode_object
<drm_mode_object>`. One of the base services it provides is tracking properties,
which are especially important for the atomic IOCTL (see `Atomic Mode
Setting`_). The somewhat surprising part here is that properties are not
directly instantiated on each object, but free-standing mode objects themselves,
represented by :c:type:`struct drm_property <drm_property>`, which only specify
the type and value range of a property. Any given property can be attached
multiple times to different objects using :c:func:`drm_object_attach_property()
<drm_object_attach_property>`.

Atomic provides transactional modeset (including planes) updates, but a
bit differently from the usual transactional approach of try-commit and
rollback:
- Firstly, no hardware changes are allowed when the commit would fail. This
allows us to implement the DRM_MODE_ATOMIC_TEST_ONLY mode, which allows
userspace to explore whether certain configurations would work or not.
- This would still allow setting and rollback of just the software state,
simplifying conversion of existing drivers. But auditing drivers for
correctness of the atomic_check code becomes really hard with that: Rolling
back changes in data structures all over the place is hard to get right.
- Lastly, for backwards compatibility and to support all use-cases, atomic
updates need to be incremental and be able to execute in parallel. Hardware
doesn't always allow it, but where possible plane updates on different CRTCs
should not interfere, and not get stalled due to output routing changing on
different CRTCs.
Taken all together there's two consequences for the atomic design:
- The overall state is split up into per-object state structures:
:c:type:`struct drm_plane_state <drm_plane_state>` for planes, :c:type:`struct
drm_crtc_state <drm_crtc_state>` for CRTCs and :c:type:`struct
drm_connector_state <drm_connector_state>` for connectors. These are the only
objects with userspace-visible and settable state. For internal state drivers
can subclass these structures through embeddeding, or add entirely new state
structures for their globally shared hardware functions.
- An atomic update is assembled and validated as an entirely free-standing pile
of structures within the :c:type:`drm_atomic_state <drm_atomic_state>`
container. Again drivers can subclass that container for their own state
structure tracking needs. Only when a state is committed is it applied to the
driver and modeset objects. This way rolling back an update boils down to
releasing memory and unreferencing objects like framebuffers.
Read on in this chapter, and also in :ref:`drm_atomic_helper` for more detailed
coverage of specific topics.
