|
||
|
+ * DOC: overview
|
||
|
+ *
|
||
|
+ * In the DRM subsystem, framebuffer pixel formats are described using the
|
||
|
+ * fourcc codes defined in `include/uapi/drm/drm_fourcc.h`. In addition to the
|
||
|
+ * fourcc code, a Format Modifier may optionally be provided, in order to
|
||
|
+ * further describe the buffer's format - for example tiling or compression.
|
||
|
+ *
|
||
|
+ * Format Modifiers
|
||
|
+ * ----------------
|
||
|
+ *
|
||
|
+ * Format modifiers are used in conjunction with a fourcc code, forming a
|
||
|
+ * unique fourcc:modifier pair. This format:modifier pair must fully define the
|
||
|
+ * format and data layout of the buffer, and should be the only way to describe
|
||
|
+ * that particular buffer.
|
||
|
+ *
|
||
|
+ * Having multiple fourcc:modifier pairs which describe the same layout should
|
||
|
+ * be avoided, as such aliases run the risk of different drivers exposing
|
||
|
+ * different names for the same data format, forcing userspace to understand
|
||
|
+ * that they are aliases.
|
||
|
+ *
|
||
|
+ * Format modifiers may change any property of the buffer, including the number
|
||
|
+ * of planes and/or the required allocation size. Format modifiers are
|
||
|
+ * vendor-namespaced, and as such the relationship between a fourcc code and a
|
||
|
+ * modifier is specific to the modifer being used. For example, some modifiers
|
||
|
+ * may preserve meaning - such as number of planes - from the fourcc code,
|
||
|
+ * whereas others may not.
|
||
|
+ *
|
||
|
+ * Modifiers must uniquely encode buffer layout. In other words, a buffer must
|
||
|
+ * match only a single modifier. A modifier must not be a subset of layouts of
|
||
|
+ * another modifier. For instance, it's incorrect to encode pitch alignment in
|
||
|
+ * a modifier: a buffer may match a 64-pixel aligned modifier and a 32-pixel
|
||
|
+ * aligned modifier. That said, modifiers can have implicit minimal
|
||
|
+ * requirements.
|
||
|
+ *
|
||
|
+ * For modifiers where the combination of fourcc code and modifier can alias,
|
||
|
+ * a canonical pair needs to be defined and used by all drivers. Preferred
|
||
|
+ * combinations are also encouraged where all combinations might lead to
|
||
|
+ * confusion and unnecessarily reduced interoperability. An example for the
|
||
|
+ * latter is AFBC, where the ABGR layouts are preferred over ARGB layouts.
|
||
|
+ *
|
||
|
+ * There are two kinds of modifier users:
|
||
|
+ *
|
||
|
+ * - Kernel and user-space drivers: for drivers it's important that modifiers
|
||
|
+ * don't alias, otherwise two drivers might support the same format but use
|
||
|
+ * different aliases, preventing them from sharing buffers in an efficient
|
||
|
+ * format.
|
||
|
+ * - Higher-level programs interfacing with KMS/GBM/EGL/Vulkan/etc: these users
|
||
|
+ * see modifiers as opaque tokens they can check for equality and intersect.
|
||
|
+ * These users musn't need to know to reason about the modifier value
|
||
|
+ * (i.e. they are not expected to extract information out of the modifier).
|
||
|
+ *
|
||
|
+ * Vendors should document their modifier usage in as much detail as
|
||
|
+ * possible, to ensure maximum compatibility across devices, drivers and
|
||
|
+ * applications.
|
||
|
+ *
|
||
|
+ * The authoritative list of format modifier codes is found in
|
||
|
+ * `include/uapi/drm/drm_fourcc.h`

|

+ * connector. User-space is expected to retrieve encoders, modes and properties
|
||

+ * by performing this ioctl at least twice: the first time to retrieve the
|
||
|
+ * number of elements, the second time to retrieve the elements themselves.
|
||
|
+ *
|
||
|
+ * To retrieve the number of elements, set @count_props and @count_encoders to
|
||
|
+ * zero, set @count_modes to 1, and set @modes_ptr to a temporary struct
|
||
|
+ * drm_mode_modeinfo element.
|
||
|
+ *
|
||
|
+ * To retrieve the elements, allocate arrays for @encoders_ptr, @modes_ptr,
|
||
|
+ * @props_ptr and @prop_values_ptr, then set @count_modes, @count_props and
|
||
|
+ * @count_encoders to their capacity.
|
||
|
+ *
|
||
|
+ * Performing the ioctl only twice may be racy: the number of elements may have
|
||
|
+ * changed with a hotplug event in-between the two ioctls. User-space is
|
||
|
+ * expected to retry the last ioctl until the number of elements stabilizes.
|
||
|
+ * The kernel won't fill any array which doesn't have the expected length.

+ *
|

|
||
|
+ *
|
||
|
+ * If the @count_modes field is set to zero and the DRM client is the current
|
||
|
+ * DRM master, the kernel will perform a forced probe on the connector to
|
||
|
+ * refresh the connector status, modes and EDID. A forced-probe can be slow,
|
||
|
+ * might cause flickering and the ioctl will block.
|
||
|
+ *
|
||
|
+ * User-space needs to force-probe connectors to ensure their metadata is
|
||
|
+ * up-to-date at startup and after receiving a hot-plug event. User-space
|
||
|
+ * may perform a forced-probe when the user explicitly requests it. User-space
|
||
|
+ * shouldn't perform a forced-probe in other situations.
