+ The DRI2 Extension
+ Version 2.0
+ 2008-09-04
+

+ Red Hat, Inc
+
+
+1. Introduction
+
+The DRI2 extension is designed to associate and access auxillary
+rendering buffers with an X drawable.
+
+DRI2 is a essentially a helper extension to support implementation of
+direct rendering drivers/libraries/technologies.
+
+The main consumer of this extension will be a direct rendering OpenGL
+driver, but the DRI2 extension is not designed to be OpenGL specific.
+Direct rendering implementations of OpenVG, Xv, cairo and other
+graphics APIs should find the functionality exposed by this extension
+helpful and hopefully sufficient.
+
+Relation to XF86DRI

+
+
+2. DRI2 Concepts
+
+
+2.1. Attachment points
+
+Stolen from OpenGL FBOs, I guess.
+
+
+2.2. Kernel rendering manager
+
+This specification assumes a rendering architechture, where an
+underlying kernel rendering manager that can provide 32 bit integer
+handles to video memory buffers. These handles can be passed between
+processes, which, through a direct rendering driver, submit rendering
+to the kernel rendering manager, targeting and/or sourcing from these
+buffers. This extension provides a means to communicate about such
+buffers as associated with an X drawable.
+
+The details of how the a direct rendering driver use the buffer names
+and submit the rendering requests is outside the scope of this
+specification. However, Appendix B does discuss implementation of
+this specification on the Graphics Execution Manager (GEM).
+
+
+2.3. Request ordering
+
+No ordering between swap buffers and X rendering. X rendering to src
+buffers will block if they have a vblank pending.
+
+
+2.4 Authentication model
+
+The purpose of the DRM authentication scheme is to grant access to the
+kernel rendering manager buffers created by the X server if, and only
+if, the client has access to the X server. This is achieved in a
+three-step protocol:
+
+ 1) The client gets a token from the kernel rendering manager
+ that uniquely identifies it. The token is a 32 bit integer.
+
+ 2) The client passes the token to the X server in the
+ DRI2Authenticate request. This request is a round trip to
+ make sure the X server has received and processed the
+ authentication before the client starts accessing the DRM.
+
+ 3) The X server authorizes the client by passing the token to
+ the kernel rendering manager.
+
+A kernel rendering manager can choose not to implement any
+authentication and just allow access to all buffers.
+
+
+2.5 Rendering to the X front buffer
+
+OpenGL allows the client to render to the front buffer, either by
+using a single-buffered configuration or but explicitly setting the
+draw buffer to GL_FRONT_LEFT. Not allowed!
+
+The client must ask for a fake front buffer, render to that and then
+use DRI2CopyRegion to copy contents back and forth between the fake
+front buffer and the real front buffer. When X and direct rendering
+to a front buffer is interleaved, it is the responsibility of the
+application to synchronize access using glXWaitGL and glXWaitX. A
+DRI2 implementation of direct rendering GLX, should use these enty
+points to copy contents back and forth to as necessary to ensure
+consistent rendering.
+
+The client may also use the DRI2SwapBuffers function to request a swap
+of the front and back buffers. If the display server supports it, this
+operation may be preferred, since it may be easier and/or more performant
+for the server to perform a simple buffer swap rather than a blit.
+
+2.6 Synchronizing rendering
+
+DRI2 provides several methods for synchronizing drawing with various events.
+The protocol for these methods is based on the SGI_video_sync and
+OML_sync_control GLX extensions. Using the DRI2WaitMSC request, a client
+can wait for a specific frame count or divisor/remainder before continuing
+its processing. With the DRI2WaitSBC request, clients can block until a given
+swap count is reached (as incremented by DRI2SwapBuffers). Finally, using
+DRI2SwapBuffers, clients can limit their frame rate by specifying a swap
+interval using the swap interval call (currently only available through GLX)
+or by using the OML swap buffers routine.
+
+2.7 Events
+
+DRI2 provides an event to indicate when a DRI2SwapBuffers request has
+been completed. This can be used to throttle drawing on the client
+side and tie into application main loops.
+
+Another event is generated when the validity of the requested buffers
+changes.

+and DRI2InvalidateBuffers.

+
+6. Protocol Types
+
+DRI2DRIVER { DRI2DriverDRI
+ DRI2DriverVDPAU,
+ DRI2DriverXV }
+
+ These values describe the type of driver the client will want
+ to load. The server sends back the name of the driver to use
+ for the screen in question.
+
+DRI2ATTACHMENT { DRI2BufferFrontLeft
+ DRI2BufferBackLeft
+ DRI2BufferFrontRight
+ DRI2BufferBackRight
+ DRI2BufferDepth
+ DRI2BufferStencil
+ DRI2BufferAccum
+ DRI2BufferFakeFrontLeft
+ DRI2BufferFakeFrontRight
+ DRI2BufferDepthStencil
+ DRI2BufferHiz }
+
+ These values describe various attachment points for DRI2
+ buffers.
+
+ In the case of video driver (DRI2DriverXV) the attachment,
+ other than DRI2BufferFrontLeft, just indicates buffer
+ number and has no other special significance. There is no
+ automatic maintenance of DRI2BufferFakeFrontLeft.
+
+DRI2BUFFER { attachment: CARD32
+ name: CARD32
+ pitch: CARD32
+ cpp: CARD32
+ flags: CARD32 }
+
+ The DRI2BUFFER describes an auxillary rendering buffer
+ associated with an X drawable. 'attachment' describes the
+ attachment point for the buffer, 'name' is the name of the
+ underlying kernel buffer.
+
+
+DRI2ATTACH_FORMAT { attachment: CARD32
+ format: CARD32 }
+
+ The DRI2ATTACH_FORMAT describes an attachment and the associated

+
+ The client sends the highest supported version to the server
+ and the server sends the highest version it supports, but no
+ higher than the requested version. Major versions changes can
+ introduce incompatibilities in existing functionality, minor
+ version changes introduce only backward compatible changes.
+ It is the clients responsibility to ensure that the server
+ supports a version which is compatible with its expectations.
+
+ Backwards compatible changes included addition of new
+ requests, but also new value types in the DRI2CopyRegion
+ request. When new values are introduced, the minor version
+ will be increased so the client can know which values the X
+ server understands from the version number.

+
+┌───
+ DRI2Connect
+ window: WINDOW
+ driverType: DRI2DRIVER
+ ▶
+ driver: STRING
+ device: STRING
+└───
+
+ Returns the driver name and device file to use for the
+ specified driver type for the screen associated with 'window'.
+
+ 'type' identifies the type of driver to query for.
+
+ 'driver' is the name of the driver to load. The client is
+ assumed to know where to look for the drivers and what to do
+ with it.
+
+ 'device' is the filename of the DRM device file.
+
+ If the client is not local, or the request driver type is
+ unknown or not available, 'driver' and 'device' will be empty
+ strings. We are not using an regular X
+ error here to indicate failure, which will allow the client
+ fall back to other options more easily.
+
+ ISSUE: We could add the list of supported attachments and the
+ supported DRI2CopyRegion values here (just the bitmask of all
+ supported values).

+ width, height: CARD32
+ buffers: LISTofDRI2BUFFER
+└───
+ Errors: Window
+
+ Get buffers for the provided attachment points with the specified
+ formats for the given drawable. Like DRI2GetBuffersWithFormat,
+ but allows the client to specify a buffer size that differs from
+ the target drawable, for example to deal with decoded video which
+ is scaled as it is blit to the front buffer (or rendered via hw
+ overlay).
+
+ The DRI2BufferFrontLeft attachment point cannot be requested. But
+ for video buffers, the client can dynamically allocate more buffers
+ by just requesting new attachment point id's. Or release a buffer
+ by requesting it with 0,0 size. If the same attachment point is
+ re-requested, then the previous buffer is deallocated and a new
+ buffer is allocated. This allows for dynamic resolution changes
+ during playback.
+
+ This request is only available with protocol version 1.4 or
+ later.
+
+: Note: originally I was not going to add a new DRI2GetBuffers variant,
+: but instead use attributes to communicate width/height. But the
+: problem is that the client blindly picks up DRI2_MINOR from dri2proto.h
+: and so there is otherwise no reliable way for the server to know if
+: client supports extra_buffers..

+ when the request is recieved, this request will return immediately.
+
+ If target_sbc is 0, this request will block the client until all

+┌───
+ DRI2SetAttribute
+ drawable: DRAWABLE
+ attribute: ATOM
+ value: LISTofCARD32
+ ▶
+└───
+ Errors: Window, Match, Value
+
+ The DRI2SetAttribute request sets the value of a drawable attribute.
+ The drawable attribute is identified by the attribute atom. The
+ following strings are guaranteed to generate valid atoms using the
+ InternAtom request.
+
+ String Size Type
+ -----------------------------------------------------------------
+
+ "XV_CSC_MATRIX" 48 4x3 matrix of floats
+ "XV_OSD" 4 XID
+
+ If the given attribute doesn't match an attribute supported by the
+ drawable a Match error is generated. The supplied encoding
+ must be one of the encodings listed for the adaptor, otherwise an
+ Encoding error is generated.
+
+ The XV_CSC_MATRIX attribute is defined to match the VDPAU
+ VdpCSCMatrix:
+
+ ┌ ┐ ┌ ┐ ┌ ┐
+ │ R │ │ m00 m01 m02 m03 │ │ Y │
+ │ G │ = │ m10 m11 m12 m13 │ * │ Cb │
+ │ B │ │ m20 m21 m22 m23 │ │ Cr │
+ └ ┘ └ ┘ │ 1.0 │
+ └ ┘
+
+ If the adaptor doesn't support the specified CSC matrix, the closest
+ values supported are assumed. The DRI2GetAttribute request can be used
+ to query the resulting values.
+
+ The "XV_OSD" attribute specifies the XID of a drawable containing
+ ARGB data to be non-destructively overlayed over the video. This
+ could be used to implement subtiles, on-screen-menus, etc. Note
+ that a DRI2DriverDRI driver could be connected to this drawable, to
+ enable GPU rendered OSD content, or alternatively normal indirect
+ X11 draw primitives can be used.
+
+ This request is only available with protocol version 1.4 or
+ later.

+
+ The DRI2GetAttribute request returns the current value of the
+ attribute identified by the given atom. If the given atom
+ doesn't match an attribute supported by the adaptor a Match

+ drawable: DRAWABLE
+ ▶
+ formats: LISTofCARD32
+└───
+ Errors: Window
+
+ Query the driver for supported formats, which can be used with
+ DRI2GetBuffersWithFormat. The 'format' describes an opaque,
+ device-dependent format for the buffer, or a fourcc for
+ non-device-dependent formats. For device-dependent formats, use
+ at least one '\0' or non 7-bit ascii character.

+ drawable: CARD32
+ ust: CARD64
+ msc: CARD64
+ sbc: CARD64
+└───
+
+ This event reports the status of the last DRI2SwapBuffers event to
+ the client. The event type should be one of DRI2_EXCHANGE_COMPLETE,
+ indicating a successful buffer exchange, DRI2_BLIT_COMPLETE, indicating
+ the swap was performed with a blit, and DRI2_FLIP_COMPLETE, indicating
+ a full page flip was completed.
+
+┌───
+ DRI2InvalidateBuffers
+ ▶
+ drawable: CARD32
+└───
+
+ This event is generated when the buffers the client had
+ requested for 'drawable' (with DRI2GetBuffers or
+ DRI2GetBuffersWithFormat) become inappropriate because they
+ don't match the drawable dimensions anymore, or a buffer swap
+ has been performed.
+
+ Note that the server is only required to warn the client once
+ about this condition, until the client takes care of bringing
+ them back up-to-date with another GetBuffers request.

+
+10. Extension Versioning
+
+The DRI2 extension has undergone a number of revisions before
+
+ 1.0: Released, but never used. Relied on a number of
+ constructs from the XF86DRI extension, such as a
+ shared memory area (SAREA) to communicate changes in
+ cliprects and window sizes, and
+
+ 1.99.1: Move the swap buffer functionality into the X server,
+ introduce SwapBuffer request to copy back buffer
+ contents to the X drawable.
+
+ 1.99.2: Rethink the SwapBuffer request as an asynchronous
+ request to copy a region between DRI2 buffers. Drop
+ CreateDrawable and DestroyDrawable, update Connect to
+ support different driver types and to send the
+ authentication group.
+
+ 1.99.3: Drop the bitmask argument intended to indicate
+ presence of optional arguments for CopyRegion.
+
+ 2.0: Awesomeness!
+
+ 2.1: True excellence. Added DRI2GetBuffersWithFormat to allow
+ more flexible object creation.
+
+ 2.2: Approaching perfection. Added requests for swapbuffers,
+ MSC and SBC related requests, and events.
+
+ 2.3: Added the DRI2InvalidateBuffers event.
+
+ 2.6: Enlightenment attained. Added the DRI2BufferHiz attachment.
+
+ 2.7: Added the DRI2GetParam request.
+
+Compatibility up to 2.0 is not preserved, but was also never released.

+
+11. Relationship with other extensions
+
+As an extension designed to support other extensions, there is
+naturally some interactions with other extensions.
+
+
+11.1 GLX
+
+The GL auxilary buffers map directly to the DRI2 buffers... eh
+
+
+11.2 DBE
+
+The DBE back buffer must correspond to the DRI2_BUFFER_FRONT_LEFT
+DRI2 buffer for servers that support both DBE and DRI2.
+
+
+11.3 XvMC / Xv
+
+We might add a DRI2_BUFFER_YUV to do vsynced colorspace conversion
+blits. Maybe... not really sure.

+ Note that cpp is unused (it is a bit difficult to represent values
+ like 1.5 bytes/pixel as an integer).
+
+ In case of multi-planar video formats, 'extra names' will give the
+ list of additional buffer names (and their pitch) if there is one
+ buffer per plane. For example, I420 has one Y plane in with a 8bit
+ luma value per pixel, followed by one U plane subsampled 2x2 (with
+ one 8bit U value per 2x2 pixel block), followed by one V plane
+ subsampled 2x2. This could either be represented as a single buffer
