From: Chia-I Wu Date: Sun, 31 Jan 2010 09:34:02 +0000 (+0800) Subject: egl: Add support for more EGLImage extensions to EGL core. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0135e5d6c83add5e539492a4899504e33f3f2434;p=mesa.git egl: Add support for more EGLImage extensions to EGL core. Add support EGL_KHR_vg_parent_image and EGL_KHR_gl_*. This is as simple as adding some flags that can be enabled. Individual drivers need to implement the extensions before enbaling the flags. --- diff --git a/src/egl/main/egldisplay.h b/src/egl/main/egldisplay.h index b04b094d847..8e3d53864b1 100644 --- a/src/egl/main/egldisplay.h +++ b/src/egl/main/egldisplay.h @@ -38,6 +38,11 @@ struct _egl_extensions EGLBoolean MESA_copy_context; EGLBoolean KHR_image_base; EGLBoolean KHR_image_pixmap; + EGLBoolean KHR_vg_parent_image; + EGLBoolean KHR_gl_texture_2D_image; + EGLBoolean KHR_gl_texture_cubemap_image; + EGLBoolean KHR_gl_texture_3D_image; + EGLBoolean KHR_gl_renderbuffer_image; char String[_EGL_MAX_EXTENSIONS_LEN]; }; diff --git a/src/egl/main/eglimage.c b/src/egl/main/eglimage.c index e7a293b3743..5732ef35ecd 100644 --- a/src/egl/main/eglimage.c +++ b/src/egl/main/eglimage.c @@ -28,8 +28,14 @@ _eglParseImageAttribList(_EGLImage *img, const EGLint *attrib_list) case EGL_IMAGE_PRESERVED_KHR: img->Preserved = val; break; + case EGL_GL_TEXTURE_LEVEL_KHR: + img->GLTextureLevel = val; + break; + case EGL_GL_TEXTURE_ZOFFSET_KHR: + img->GLTextureZOffset = val; + break; default: - err = EGL_BAD_ATTRIBUTE; + /* unknown attrs are ignored */ break; } @@ -52,6 +58,8 @@ _eglInitImage(_EGLImage *img, _EGLDisplay *dpy, const EGLint *attrib_list) img->Resource.Display = dpy; img->Preserved = EGL_FALSE; + img->GLTextureLevel = 0; + img->GLTextureZOffset = 0; err = _eglParseImageAttribList(img, attrib_list); if (err != EGL_SUCCESS) diff --git a/src/egl/main/eglimage.h b/src/egl/main/eglimage.h index 26bf054a07d..2c0fb16d1d3 100644 --- a/src/egl/main/eglimage.h +++ b/src/egl/main/eglimage.h @@ -15,6 +15,8 @@ struct _egl_image _EGLResource Resource; EGLBoolean Preserved; + EGLint GLTextureLevel; + EGLint GLTextureZOffset; }; diff --git a/src/egl/main/eglmisc.c b/src/egl/main/eglmisc.c index 907a057b442..984e426686e 100644 --- a/src/egl/main/eglmisc.c +++ b/src/egl/main/eglmisc.c @@ -38,6 +38,30 @@ #include "egldisplay.h" +/** + * Copy the extension into the string and update the string pointer. + */ +static EGLint +_eglAppendExtension(char **str, const char *ext) +{ + char *s = *str; + EGLint len = strlen(ext); + + if (s) { + memcpy(s, ext, len); + s[len++] = ' '; + s[len] = '\0'; + + *str += len; + } + else { + len++; + } + + return len; +} + + /** * Examine the individual extension enable/disable flags and recompute * the driver's Extensions string. @@ -45,24 +69,34 @@ static void _eglUpdateExtensionsString(_EGLDisplay *dpy) { +#define _EGL_CHECK_EXTENSION(ext) \ + do { \ + if (dpy->Extensions.ext) { \ + _eglAppendExtension(&exts, "EGL_" #ext); \ + assert(exts <= dpy->Extensions.String + _EGL_MAX_EXTENSIONS_LEN); \ + } \ + } while (0) + char *exts = dpy->Extensions.String; if (exts[0]) return; - if (dpy->Extensions.MESA_screen_surface) - strcat(exts, "EGL_MESA_screen_surface "); - if (dpy->Extensions.MESA_copy_context) - strcat(exts, "EGL_MESA_copy_context "); + _EGL_CHECK_EXTENSION(MESA_screen_surface); + _EGL_CHECK_EXTENSION(MESA_copy_context); - if (dpy->Extensions.KHR_image_base) - strcat(exts, "EGL_KHR_image_base "); - if (dpy->Extensions.KHR_image_pixmap) - strcat(exts, "EGL_KHR_image_pixmap "); + _EGL_CHECK_EXTENSION(KHR_image_base); + _EGL_CHECK_EXTENSION(KHR_image_pixmap); if (dpy->Extensions.KHR_image_base && dpy->Extensions.KHR_image_pixmap) - strcat(exts, "EGL_KHR_image "); + _eglAppendExtension(&exts, "EGL_KHR_image"); + + _EGL_CHECK_EXTENSION(KHR_vg_parent_image); + _EGL_CHECK_EXTENSION(KHR_gl_texture_2D_image); + _EGL_CHECK_EXTENSION(KHR_gl_texture_cubemap_image); + _EGL_CHECK_EXTENSION(KHR_gl_texture_3D_image); + _EGL_CHECK_EXTENSION(KHR_gl_renderbuffer_image); - assert(strlen(exts) < _EGL_MAX_EXTENSIONS_LEN); +#undef _EGL_CHECK_EXTENSION }
