From: Jon Smirl Date: Fri, 13 May 2005 18:31:35 +0000 (+0000) Subject: First attempt at getting egl support up on dumb framebuffer. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7012d01d888d482f2c6ad1180231a482026d213a;p=mesa.git First attempt at getting egl support up on dumb framebuffer. Seems to be mostly working. Not all of egl API is implemented. --- diff --git a/configs/linux-solo b/configs/linux-solo index 9b739c29fd1..cd9d72050ea 100644 --- a/configs/linux-solo +++ b/configs/linux-solo @@ -15,16 +15,16 @@ CFLAGS = $(DEFINES) -Wmissing-prototypes -g -std=c99 -Wundef -fPIC -ffast-math CXXFLAGS = $(DEFINES) -Wall -O3 -ansi -pedantic -fPIC # Library/program dependencies -DRI_LIB_DEPS = -lm -lpthread -lexpat -ldl +DRI_LIB_DEPS = -lm -lpthread -lexpat -ldl -L$(LIB_DIR) -lEGL -l$(GL_LIB) GL_LIB_DEPS = -lm -lpthread -ldl GLU_LIB_DEPS = -L$(LIB_DIR) -l$(GL_LIB) -lm GLUT_LIB_DEPS = -L$(LIB_DIR) -l$(GLU_LIB) -l$(GL_LIB) -lm APP_LIB_DEPS = -L$(LIB_DIR) -l$(GLUT_LIB) -l$(GLU_LIB) -l$(GL_LIB) -lm -lpthread # Directories -SRC_DIRS = mesa glx/mini glu glut/mini +SRC_DIRS = mesa egl glx/mini glu glut/mini DRIVER_DIRS = dri -PROGRAM_DIRS = miniglx +PROGRAM_DIRS = miniglx egl -#DRI_DIRS = fb ffb gamma sis savage +#DRI_DIRS = ffb gamma sis savage DRI_DIRS = i810 i830 i915 mach64 mga r128 r200 radeon tdfx unichrome fb diff --git a/include/GLES/egl.h b/include/GLES/egl.h index 64acb722a22..c4fc4ad543c 100644 --- a/include/GLES/egl.h +++ b/include/GLES/egl.h @@ -249,11 +249,13 @@ GLAPI EGLBoolean APIENTRY eglGetModesMESA(EGLDisplay dpy, EGLScreenMESA screen, GLAPI EGLBoolean APIENTRY eglGetModeAttribMESA(EGLDisplay dpy, EGLModeMESA mode, EGLint attribute, EGLint *value);

The \c fb_format specifies which color components are in + * each pixel and what the default order is. For example, \c GL_RGB specifies + * that red, green, blue are available and red is in the "most significant" + * position and blue is in the "least significant". The \c fb_type specifies + * the bit sizes of each component and the actual ordering. For example, if + * \c GL_UNSIGNED_SHORT_5_6_5_REV is specified with \c GL_RGB, bits [15:11] + * are the blue value, bits [10:5] are the green value, and bits [4:0] are + * the red value. + * + * One sublte issue is the combination of \c GL_RGB or \c GL_BGR and either + * of the \c GL_UNSIGNED_INT_8_8_8_8 modes. The resulting mask values in the + * \c __GLcontextModes structure is \b identical to the \c GL_RGBA or + * \c GL_BGRA case, except the \c alphaMask is zero. This means that, as + * far as this routine is concerned, \c GL_RGB with \c GL_UNSIGNED_INT_8_8_8_8 + * still uses 32-bits. + * + * If in doubt, look at the tables used in the function. + * + * \param ptr_to_modes Pointer to a pointer to a linked list of + * \c __GLcontextModes. Upon completion, a pointer to + * the next element to be process will be stored here. + * If the function fails and returns \c GL_FALSE, this + * value will be unmodified, but some elements in the + * linked list may be modified. + * \param fb_format Format of the framebuffer. Currently only \c GL_RGB, + * \c GL_RGBA, \c GL_BGR, and \c GL_BGRA are supported. + * \param fb_type Type of the pixels in the framebuffer. Currently only + * \c GL_UNSIGNED_SHORT_5_6_5, + * \c GL_UNSIGNED_SHORT_5_6_5_REV, + * \c GL_UNSIGNED_INT_8_8_8_8, and + * \c GL_UNSIGNED_INT_8_8_8_8_REV are supported. + * \param depth_bits Array of depth buffer sizes to be exposed. + * \param stencil_bits Array of stencil buffer sizes to be exposed. + * \param num_depth_stencil_bits Number of entries in both \c depth_bits and + * \c stencil_bits. + * \param db_modes Array of buffer swap modes. If an element has a + * value of \c GLX_NONE, then it represents a + * single-buffered mode. Other valid values are + * \c GLX_SWAP_EXCHANGE_OML, \c GLX_SWAP_COPY_OML, and + * \c GLX_SWAP_UNDEFINED_OML.
