- EGL Extension #not assigned
-
-Dependencies
-
- Requires EGL 1.4 or later. This extension is written against the
- wording of the EGL 1.4 specification.
-
- EGL_KHR_base_image is required.
-
-Overview
-
- This extension provides entry points for integrating EGLImage with the
- Linux DRM mode setting and memory management drivers. The extension
- lets applications create EGLImages without a client API resource and
- lets the application get the DRM buffer handles.
-
-IP Status
-
- Open-source; freely implementable.
-
-New Procedures and Functions
-
- EGLImageKHR eglCreateDRMImageMESA(EGLDisplay dpy,
- const EGLint *attrib_list);
-
- EGLBoolean eglExportDRMImageMESA(EGLDisplay dpy,
- EGLImageKHR image,
- EGLint *name,
- EGLint *handle,
- EGLint *stride);
-
-New Tokens
-
- Accepted in the <attrib_list> parameter of eglCreateDRMImageMESA:
-
- EGL_DRM_BUFFER_FORMAT_MESA 0x31D0
- EGL_DRM_BUFFER_USE_MESA 0x31D1
-
- Accepted as values for the EGL_IMAGE_FORMAT_MESA attribute:
-
- EGL_DRM_BUFFER_FORMAT_ARGB32_MESA 0x31D2
-
- Bits accepted in EGL_DRM_BUFFER_USE_MESA:
-
- EGL_DRM_BUFFER_USE_SCANOUT_MESA 0x0001
- EGL_DRM_BUFFER_USE_SHARE_MESA 0x0002
-
- Accepted in the <target> parameter of eglCreateImageKHR:
-
- EGL_DRM_BUFFER_MESA 0x31D3
-
- Use when importing drm buffer:
-
- EGL_DRM_BUFFER_STRIDE_MESA 0x31D4
- EGL_DRM_BUFFER_FORMAT_MESA 0x31D0
-
-Additions to the EGL 1.4 Specification:
-
- To create a DRM EGLImage, call
-
- EGLImageKHR eglCreateDRMImageMESA(EGLDisplay dpy,
- const EGLint *attrib_list);
-
- In the attribute list, pass EGL_WIDTH, EGL_HEIGHT and format and
- use in the attrib list using EGL_DRM_BUFFER_FORMAT_MESA and
- EGL_DRM_BUFFER_USE_MESA. The only format specified by this
- extension is EGL_DRM_BUFFER_FORMAT_ARGB32_MESA, where each pixel
- is a CPU-endian, 32-bit quantity, with alpha in the upper 8 bits,
- then red, then green, then blue. The bit values accepted by
- EGL_DRM_BUFFER_USE_MESA are EGL_DRM_BUFFER_USE_SCANOUT_MESA and
- EGL_DRM_BUFFER_USE_SHARE_MESA. EGL_DRM_BUFFER_USE_SCANOUT_MESA
- requests that the created EGLImage should be usable as a scanout
- buffer with the DRM kernel modesetting API. The
- EGL_DRM_BUFFER_USE_SHARE_MESA bit requests that the EGLImage can
- be shared with other processes by passing the underlying DRM
- buffer name.
-
- To create a process local handle or a global DRM name for a
- buffer, call
-
- EGLBoolean eglExportDRMImageMESA(EGLDisplay dpy,
- EGLImageKHR image,
- EGLint *name,
- EGLint *handle,
- EGLint *stride);
-
- If <name> is non-NULL, a global name is assigned to the image and
- written to <name>, the handle (local to the DRM file descriptor,
- for use with DRM kernel modesetting API) is written to <handle> if
- non-NULL and the stride (in bytes) is written to <stride>, if
- non-NULL.
-
- Import a shared buffer by calling eglCreateImageKHR with
- EGL_DRM_BUFFER_MESA as the target, using EGL_WIDTH, EGL_HEIGHT,
- EGL_DRM_BUFFER_FORMAT_MESA, EGL_DRM_BUFFER_STRIDE_MESA
- in the attrib list.
-
-Issues
-
- 1. Why don't we use eglCreateImageKHR with a target that
- indicates that we want to create an EGLImage from scratch?
-
- RESOLVED: The eglCreateImageKHR entry point is reserved for
- creating an EGLImage from an already existing client API
- resource. This is fine when we're creating the EGLImage from
- an existing DRM buffer name, it doesn't seem right to overload
- the function to also allocate the underlying resource.
-
- 2. Why don't we use an eglQueryImageMESA type functions for
- querying the DRM EGLImage attributes (name, handle, and stride)?
-
- RESOLVED: The eglQueryImage function has been proposed often,
- but it goes against the EGLImage design. EGLImages are opaque
- handles to a 2D array of pixels, which can be passed between
- client APIs. By referencing an EGLImage in a client API, the
- EGLImage target (a texture, a renderbuffer or such) can be
- used to query the attributes of the EGLImage. We don't have a
- full client API for creating and querying DRM buffers, though,
- so we use a new EGL extension entry point instead.

-<H1>Mesa 7.11 Release Notes / (release date TBD)</H1>
-
-<p>
-Mesa 7.11 is a new development release.
-People who are concerned with stability and reliability should stick
-with a previous release or wait for Mesa 7.11.1.
-</p>
-<p>
-Mesa 7.11 implements the OpenGL 2.1 API, but the version reported by
-glGetString(GL_VERSION) depends on the particular driver being used.
-Some drivers don't support all the features required in OpenGL 2.1.
-</p>
-<p>
-See the <a href="install.html">Compiling/Installing page</a> for prerequisites
-for DRI hardware acceleration.
