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 is non-NULL, a global name is assigned to the image and + written to , the handle (local to the DRM file descriptor, + for use with DRM kernel modesetting API) is written to if + non-NULL and the stride (in bytes) is written to , 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 referenceing 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. + +Revision History + + Version 1, June 3, 2010 + Initial draft (Kristian Høgsberg) + Version 2, August 25, 2010 + Flesh out the extension a bit, add final EGL tokens, capture + some of the original discussion in the issues section. diff --git a/include/EGL/eglext.h b/include/EGL/eglext.h index 171892c93e..04603931b3 100644 --- a/include/EGL/eglext.h +++ b/include/EGL/eglext.h @@ -120,6 +120,29 @@ typedef EGLBoolean (EGLAPIENTRYP PFNEGLDESTROYIMAGEKHRPROC) (EGLDisplay dpy, EGL #define EGL_GL_RENDERBUFFER_KHR 0x30B9 /* eglCreateImageKHR target */ #endif +#ifndef EGL_MESA_drm_image +#define EGL_MESA_drm_image 1 +#define EGL_DRM_BUFFER_FORMAT_MESA 0x31D0 /* eglCreateImageKHR attribute */ +#define EGL_DRM_BUFFER_USE_MESA 0x31D1 + +/* EGL_DRM_BUFFER_FORMAT_MESA tokens */ +#define EGL_DRM_BUFFER_FORMAT_ARGB32_MESA 0x31D2 + +/* EGL_DRM_BUFFER_USE_MESA bits */ +#define EGL_DRM_BUFFER_USE_SCANOUT_MESA 0x0001 +#define EGL_DRM_BUFFER_USE_SHARE_MESA 0x0002 + +#define EGL_DRM_BUFFER_MESA 0x31D3 /* eglCreateImageKHR target */ +#define EGL_DRM_BUFFER_STRIDE_MESA 0x31D4 /* eglCreateImageKHR attribute */ + +#ifdef EGL_EGLEXT_PROTOTYPES +EGLAPI EGLImageKHR EGLAPIENTRY eglCreateDRMImageMESA(EGLDisplay dpy, const EGLint *attrib_list); +EGLAPI EGLBoolean EGLAPIENTRY eglExportDRMImageMESA(EGLDisplay dpy, EGLImageKHR image, EGLint *name, EGLint *handle, EGLint *stride); +#endif +typedef EGLImageKHR (EGLAPIENTRYP PFNEGLCREATEDRMIMAGEMESA) (EGLDisplay dpy, const EGLint *attrib_list); +typedef EGLBoolean (EGLAPIENTRYP PFNEGLEXPORTDRMIMAGEMESA) (EGLDisplay dpy, EGLImageKHR image, EGLint *name, EGLint *handle, EGLint *stride); +#endif + #if KHRONOS_SUPPORT_INT64 /* EGLTimeKHR requires 64-bit uint support */ #ifndef EGL_KHR_reusable_sync #define EGL_KHR_reusable_sync 1 diff --git a/src/egl/main/eglapi.c b/src/egl/main/eglapi.c index c62459ec6f..31c5419bbc 100644 --- a/src/egl/main/eglapi.c +++ b/src/egl/main/eglapi.c @@ -893,6 +893,10 @@ eglGetProcAddress(const char *procname) #endif /* EGL_KHR_image_base */ #ifdef EGL_NOK_swap_region { "eglSwapBuffersRegionNOK", (_EGLProc) eglSwapBuffersRegionNOK }, +#endif +#ifdef EGL_MESA_drm_image + { "eglCreateDRMImageMESA", (_EGLProc) eglCreateDRMImageMESA }, + { "eglExportDRMImageMESA", (_EGLProc) eglExportDRMImageMESA }, #endif { NULL, NULL } }; @@ -1416,3 +1420,42 @@ eglSwapBuffersRegionNOK(EGLDisplay dpy, EGLSurface surface, } #endif /* EGL_NOK_swap_region */ + + +#ifdef EGL_MESA_drm_image + +EGLImageKHR EGLAPIENTRY +eglCreateDRMImageMESA(EGLDisplay dpy, const EGLint *attr_list) +{ + _EGLDisplay *disp = _eglLockDisplay(dpy); + _EGLDriver *drv; + _EGLImage *img; + EGLImageKHR ret; + + _EGL_CHECK_DISPLAY(disp, EGL_NO_IMAGE_KHR, drv); + + img = drv->API.CreateDRMImageMESA(drv, disp, attr_list); + ret = (img) ?
