+ For consistency this documentation uses American English. Abbreviations
+ are written as all-uppercase, for example: DRM, KMS, IOCTL, CRTC, and so
+ on. To aid in reading, documentations make full use of the markup
+ characters kerneldoc provides: @parameter for function parameters, @member
+ for structure members, &structure to reference structures and
+ function() for functions. These all get automatically hyperlinked if
+ kerneldoc for the referenced objects exists. When referencing entries in
+ function vtables please use ->vfunc(). Note that kerneldoc does
+ not support referencing struct members directly, so please add a reference
+ to the vtable struct somewhere in the same paragraph or at least section.
+ </para>
+ <para>
+ Except in special situations (to separate locked from unlocked variants)
+ locking requirements for functions aren't documented in the kerneldoc.
+ Instead locking should be check at runtime using e.g.
+ <code>WARN_ON(!mutex_is_locked(...));</code>. Since it's much easier to
+ ignore documentation than runtime noise this provides more value. And on
+ top of that runtime checks do need to be updated when the locking rules
+ change, increasing the chances that they're correct. Within the
+ documentation the locking rules should be explained in the relevant
+ structures: Either in the comment for the lock explaining what it
+ protects, or data fields need a note about which lock protects them, or
+ both.
+ </para>
+ <para>
+ Functions which have a non-<code>void</code> return value should have a
+ section called "Returns" explaining the expected return values in
+ different cases and their meanings. Currently there's no consensus whether
+ that section name should be all upper-case or not, and whether it should
+ end in a colon or not. Go with the file-local style. Other common section
+ names are "Notes" with information for dangerous or tricky corner cases,
+ and "FIXME" where the interface could be cleaned up.

- <para>
- Schedule a page flip to the given frame buffer for the CRTC. This
- operation is called with the mode config mutex held.
- </para>
- <para>
- Page flipping is a synchronization mechanism that replaces the frame
- buffer being scanned out by the CRTC with a new frame buffer during
- vertical blanking, avoiding tearing. When an application requests a page
- flip the DRM core verifies that the new frame buffer is large enough to
- be scanned out by the CRTC in the currently configured mode and then
- calls the CRTC <methodname>page_flip</methodname> operation with a
- pointer to the new frame buffer.
- </para>
- <para>
- The <methodname>page_flip</methodname> operation schedules a page flip.
- Once any pending rendering targeting the new frame buffer has
- completed, the CRTC will be reprogrammed to display that frame buffer
- after the next vertical refresh. The operation must return immediately
- without waiting for rendering or page flip to complete and must block
- any new rendering to the frame buffer until the page flip completes.
- </para>
- <para>
- If a page flip can be successfully scheduled the driver must set the
- <code>drm_crtc->fb</code> field to the new framebuffer pointed to
- by <code>fb</code>. This is important so that the reference counting
- on framebuffers stays balanced.
- </para>
- <para>
- If a page flip is already pending, the
- <methodname>page_flip</methodname> operation must return
- -<errorname>EBUSY</errorname>.
- </para>
- <para>
- To synchronize page flip to vertical blanking the driver will likely
- need to enable vertical blanking interrupts. It should call
- <function>drm_vblank_get</function> for that purpose, and call
- <function>drm_vblank_put</function> after the page flip completes.
- </para>
- <para>
- If the application has requested to be notified when page flip completes
- the <methodname>page_flip</methodname> operation will be called with a
- non-NULL <parameter>event</parameter> argument pointing to a
- <structname>drm_pending_vblank_event</structname> instance. Upon page
- flip completion the driver must call <methodname>drm_send_vblank_event</methodname>
- to fill in the event and send to wake up any waiting processes.
- This can be performed with
- <programlisting><![CDATA[
- spin_lock_irqsave(&dev->event_lock, flags);
- ...
- drm_send_vblank_event(dev, pipe, event);
- spin_unlock_irqrestore(&dev->event_lock, flags);
- ]]></programlisting>
- </para>
- <note><para>
- FIXME: Could drivers that don't need to wait for rendering to complete
- just add the event to <literal>dev->vblank_event_list</literal> and
- let the DRM core handle everything, as for "normal" vertical blanking
- events?
- </para></note>
- <para>
- While waiting for the page flip to complete, the
- <literal>event->base.link</literal> list head can be used freely by
- the driver to store the pending event in a driver-specific list.
- </para>
- <para>
- If the file handle is closed before the event is signaled, drivers must
- take care to destroy the event in their
- <methodname>preclose</methodname> operation (and, if needed, call
- <function>drm_vblank_put</function>).

- first tries to locate the best encoder for each connector by calling
- the connector <methodname>best_encoder</methodname> helper
- operation.
- </para>
- <para>
- After locating the appropriate encoders, the helper function will
- call the <methodname>mode_fixup</methodname> encoder and CRTC helper
- operations to adjust the requested mode, or reject it completely in
- which case an error will be returned to the application. If the new
- configuration after mode adjustment is identical to the current
- configuration the helper function will return without performing any
- other operation.
- </para>
- <para>
- If the adjusted mode is identical to the current mode but changes to
- the frame buffer need to be applied, the
- <function>drm_crtc_helper_set_config</function> function will call
- the CRTC <methodname>mode_set_base</methodname> helper operation. If
- the adjusted mode differs from the current mode, or if the
- <methodname>mode_set_base</methodname> helper operation is not
- provided, the helper function performs a full mode set sequence by
- calling the <methodname>prepare</methodname>,
- <methodname>mode_set</methodname> and
- <methodname>commit</methodname> CRTC and encoder helper operations,
- in that order.
- </para>
- </listitem>
- <listitem>
- <synopsis>void drm_helper_connector_dpms(struct drm_connector *connector, int mode);</synopsis>
- <para>
- The <function>drm_helper_connector_dpms</function> helper function
- is a connector <methodname>dpms</methodname> implementation that
- tracks power state of connectors. To use the function, drivers must
- provide <methodname>dpms</methodname> helper operations for CRTCs
- and encoders to apply the DPMS state to the device.
- </para>
- <para>
- The mid-layer doesn't track the power state of CRTCs and encoders.
- The <methodname>dpms</methodname> helper operations can thus be
- called with a mode identical to the currently active mode.

- <listitem>
- <synopsis>int drm_helper_probe_single_connector_modes(struct drm_connector *connector,
- uint32_t maxX, uint32_t maxY);</synopsis>
- <para>
- The <function>drm_helper_probe_single_connector_modes</function> helper
- function is a connector <methodname>fill_modes</methodname>
- implementation that updates the connection status for the connector
- and then retrieves a list of modes by calling the connector
- <methodname>get_modes</methodname> helper operation.
- </para>
- <para>
- If the helper operation returns no mode, and if the connector status
- is connector_status_connected, standard VESA DMT modes up to
- 1024x768 are automatically added to the modes list by a call to
- <function>drm_add_modes_noedid</function>.
- </para>
- <para>
- The function then filters out modes larger than
- <parameter>max_width</parameter> and <parameter>max_height</parameter>
- if specified. It finally calls the optional connector
- <methodname>mode_valid</methodname> helper operation for each mode in
- the probed list to check whether the mode is valid for the connector.

+Device-Tree bindings for Samsung Exynos Embedded DisplayPort Transmitter(eDP)
+
+DisplayPort is industry standard to accommodate the growing board adoption
+of digital display technology within the PC and CE industries.
+It consolidates the internal and external connection methods to reduce device
+complexity and cost. It also supports necessary features for important cross
+industry applications and provides performance scalability to enable the next
+generation of displays that feature higher color depths, refresh rates, and
+display resolutions.
+
+eDP (embedded display port) device is compliant with Embedded DisplayPort
+standard as follows,
+- DisplayPort standard 1.1a for Exynos5250 and Exynos5260.
+- DisplayPort standard 1.3 for Exynos5422s and Exynos5800.
+
+eDP resides between FIMD and panel or FIMD and bridge such as LVDS.

+ *
+ * After locating the appropriate encoders, the helper function will call the

+ * will call the CRTC ->mode_set_base() (struct &drm_crtc_helper_funcs) helper
+ * operation.
+ *
+ * If the adjusted mode differs from the current mode, or if the
+ * ->mode_set_base() helper operation is not provided, the helper function
+ * performs a full mode set sequence by calling the ->prepare(), ->mode_set()
+ * and ->commit() CRTC and encoder helper operations, in that order.
+ * Alternatively it can also use the dpms and disable helper operations. For

+ * drm_helper_probe_single_connector_modes - get complete set of display modes
+ * @connector: connector to probe
+ * @maxX: max width for modes
+ * @maxY: max height for modes
+ *
+ * Based on the helper callbacks implemented by @connector in struct
+ * &drm_connector_helper_funcs try to detect all valid modes. Modes will first
+ * be added to the connector's probed_modes list, then culled (based on validity
+ * and the @maxX, @maxY parameters) and put into the normal modes list.
+ *
+ * Intended to be used as a generic implementation of the ->fill_modes()
+ * @connector vfunc for drivers that use the CRTC helpers for output mode
+ * filtering and detection.
+ *
+ * The basic procedure is as follows
+ *
+ * 1. All modes currently on the connector's modes list are marked as stale
+ *
+ * 2. New modes are added to the connector's probed_modes list with
+ * drm_mode_probed_add(). New modes start their life with status as OK.
+ * Modes are added from a single source using the following priority order.
+ *
+ * - debugfs 'override_edid' (used for testing only)
+ * - firmware EDID (drm_load_edid_firmware())
+ * - connector helper ->get_modes() vfunc
+ * - if the connector status is connector_status_connected, standard
+ * VESA DMT modes up to 1024x768 are automatically added
+ * (drm_add_modes_noedid())
+ *
+ * Finally modes specified via the kernel command line (video=...) are
+ * added in addition to what the earlier probes produced
+ * (drm_helper_probe_add_cmdline_mode()). These modes are generated
+ * using the VESA GTF/CVT formulas.
+ *
+ * 3. Modes are moved from the probed_modes list to the modes list. Potential
+ * duplicates are merged together (see drm_mode_connector_list_update()).
+ * After this step the probed_modes list will be empty again.
+ *
+ * 4. Any non-stale mode on the modes list then undergoes validation
+ *
+ * - drm_mode_validate_basic() performs basic sanity checks
+ * - drm_mode_validate_size() filters out modes larger than @maxX and @maxY
+ * (if specified)
+ * - drm_mode_validate_flag() checks the modes againt basic connector
+ * capabilites (interlace_allowed,doublescan_allowed,stereo_allowed)
+ * - the optional connector ->mode_valid() helper can perform driver and/or
+ * hardware specific checks
+ *
+ * 5. Any mode whose status is not OK is pruned from the connector's modes list,
+ * accompanied by a debug message indicating the reason for the mode's
+ * rejection (see drm_mode_prune_invalid()).
+ *
+ * Returns:
+ * The number of modes found on @connector.

+ * overwriting system memory (drawing to it as a framebuffer) or
+ * reading system memory it shouldn't (reading it as a texture, or
+ * uniform data, or vertex data).
+ *
+ * This validates command lists to ensure that all accesses are within
+ * the bounds of the GEM objects referenced. It explicitly whitelists
+ * packets, and looks at the offsets in any address fields to make
+ * sure they're constrained within the BOs they reference.
+ *
+ * Note that because of the validation that's happening anyway, this

+ * Page flipping is a synchronization mechanism that replaces the frame

+ * vertical blanking, avoiding tearing (except when requested otherwise
+ * through the DRM_MODE_PAGE_FLIP_ASYNC flag). When an application
+ * requests a page flip the DRM core verifies that the new frame buffer
+ * is large enough to be scanned out by the CRTC in the currently
+ * configured mode and then calls the CRTC ->page_flip() operation with a
+ * pointer to the new frame buffer.
+ *
+ * The driver must wait for any pending rendering to the new framebuffer
+ * to complete before executing the flip. It should also wait for any
+ * pending rendering from other drivers if the underlying buffer is a
+ * shared dma-buf.
+ *
+ * An application can request to be notified when the page flip has
+ * completed. The drm core will supply a struct &drm_event in the event
+ * parameter in this case. This can be handled by the
+ * drm_crtc_send_vblank_event() function, which the driver should call on
+ * the provided event upon completion of the flip. Note that if
+ * the driver supports vblank signalling and timestamping the vblank
+ * counters and timestamps must agree with the ones returned from page
+ * flip events. With the current vblank helper infrastructure this can
+ * be achieved by holding a vblank reference while the page flip is
+ * pending, acquired through drm_crtc_vblank_get() and released with
+ * drm_crtc_vblank_put(). Drivers are free to implement their own vblank
+ * counter and timestamp tracking though, e.g. if they have accurate
+ * timestamp registers in hardware.
+ *
+ * FIXME:
+ *
+ * Up to that point drivers need to manage events themselves and can use
+ * even->base.list freely for that. Specifically they need to ensure
+ * that they don't send out page flip (or vblank) events for which the
+ * corresponding drm file has been closed already. The drm core

+ * ->preclose driver function.

+ * expected to request delivery of an event and wait with recycling old

+ * @atomic_commit:
+ *
+ * This is the only hook to commit an atomic modeset update. The core
+ * guarantees that @atomic_check has been called successfully before
+ * calling this function, and that nothing has been changed in the
+ * interim.
+ *
+ * See the documentation for struct &drm_atomic_state for how exactly
+ * an atomic modeset update is described.
+ *
+ * Drivers using the atomic helpers can implement this hook using
+ * drm_atomic_helper_commit(), or one of the exported sub-functions of
+ * it.
+ *
+ * Asynchronous commits (as indicated with the async parameter) must
+ * do any preparatory work which might result in an unsuccessful commit
+ * in the context of this callback. The only exceptions are hardware
+ * errors resulting in -EIO. But even in that case the driver must
+ * ensure that the display pipe is at least running, to avoid
+ * compositors crashing when pageflips don't work. Anything else,
+ * specifically committing the update to the hardware, should be done
+ * without blocking the caller. For updates which do not require a
+ * modeset this must be guaranteed.
+ *
+ * The driver must wait for any pending rendering to the new
+ * framebuffers to complete before executing the flip. It should also
+ * wait for any pending rendering from other drivers if the underlying
+ * buffer is a shared dma-buf. Asynchronous commits must not wait for
+ * rendering in the context of this callback.
+ *
+ * An application can request to be notified when the atomic commit has
+ * completed. These events are per-CRTC and can be distinguished by the
+ * CRTC index supplied in &drm_event to userspace.
+ *
+ * The drm core will supply a struct &drm_event in the event
+ * member of each CRTC's &drm_crtc_state structure. This can be handled by the
+ * drm_crtc_send_vblank_event() function, which the driver should call on
+ * the provided event upon completion of the atomic commit. Note that if
+ * the driver supports vblank signalling and timestamping the vblank
+ * counters and timestamps must agree with the ones returned from page
+ * flip events. With the current vblank helper infrastructure this can
+ * be achieved by holding a vblank reference while the page flip is
+ * pending, acquired through drm_crtc_vblank_get() and released with
+ * drm_crtc_vblank_put(). Drivers are free to implement their own vblank
+ * counter and timestamp tracking though, e.g. if they have accurate
+ * timestamp registers in hardware.
+ *
+ * NOTE:
+ *
+ * Drivers are not allowed to shut down any display pipe successfully
+ * enabled through an atomic commit on their own. Doing so can result in
+ * compositors crashing if a page flip is suddenly rejected because the
+ * pipe is off.
+ *
+ * RETURNS:
+ *
+ * 0 on success or one of the below negative error codes:
+ *
+ * - -EBUSY, if an asynchronous updated is requested and there is
+ * an earlier updated pending. Drivers are allowed to support a queue
+ * of outstanding updates, but currently no driver supports that.
+ * Note that drivers must wait for preceding updates to complete if a
+ * synchronous update is requested, they are not allowed to fail the
+ * commit in that case.
+ *
+ * - -ENOMEM, if the driver failed to allocate memory. Specifically
+ * this can happen when trying to pin framebuffers, which must only
+ * be done when committing the state.
+ *
+ * - -ENOSPC, as a refinement of the more generic -ENOMEM to indicate
+ * that the driver has run out of vram, iommu space or similar GPU
+ * address space needed for framebuffer.
+ *
+ * - -EIO, if the hardware completely died.
+ *
+ * - -EINTR, -EAGAIN or -ERESTARTSYS, if the IOCTL should be restarted.
+ * This can either be due to a pending signal, or because the driver
+ * needs to completely bail out to recover from an exceptional
+ * situation like a GPU hang. From a userspace point of view all errors are
+ * treated equally.
+ *
+ * This list is exhaustive. Specifically this hook is not allowed to
+ * return -EINVAL (any invalid requests should be caught in
+ * @atomic_check) or -EDEADLK (this function must not acquire
+ * additional modeset locks).
