Listed in no particular order. + +1) No input events + +MiniGLX doesn't provide an input layer, so any X11 input event +handling in the existing app will have to be redone for whatever +input devices exist on the target. + +2) No configuration, expose events + +Many GLX and Xlib programs wait on an event to ensure the window has +become visible after being mapped. MiniGLX provides no equivalent +facility. + +3) Different headers + +X11/Xlib.h, GL/GLX.h, etc must not be used if the program is being +compiled against MiniGLX. + +The equivalent header is GL/MiniGLX.h. + +4) Different library + +It may be necessary to link directly against the minGLX libGL.so. + +5) Reduced number of Xlib and GLX entrypoints. + +By definition (MiniGLX is a subset of GLX), many Xlib and GLX +entrypoints, structures and macros are not present in MiniGLX. It +will be necessary to find and eliminate all references to +non-supported entrypoints. + + +--------------------------------------------------------------- + +Bugs in radeonfb.o -- the radeon framebuffer driver. +---------------------------------------------------- + +Several bugs have been found in the radeonfb.o framebuffer driver. +Most of these are resolved in the version included in the MiniGLX +sources, but some remain: + +1) Occasionally, after entering graphics mode, colors appear 'shifted' +or 'translated', particularly in higher resolution modes. This is +definitely a bug in radeonfb.o as this can be provoked even when using +the software dri driver (fb_dri.so). Importance: High. Workaround: +Use 800x600 as it seems to be less frequent at this resolution, +otherwise, restart the application. + + + diff --git a/src/glx/mini/dispatch.c b/src/glx/mini/dispatch.c new file mode 100644 index 0000000000..264cd4cba8 --- /dev/null +++ b/src/glx/mini/dispatch.c @@ -0,0 +1,64 @@ +/** + * \file miniglx/dispatch.c + * + * \brief C-based dispatch of the OpenGL entry points (glAccum(), glBegin(), + * etc). + * + * \author Brian Paul <brian@precisioninsight.com> + * + * \note This code IS NOT USED if we're compiling on an x86 system and using + * the glapi_x86.S assembly code. + */ + +/* + * Copyright 1998-1999 Precision Insight, Inc., Cedar Park, Texas. + * All Rights Reserved. + * + * Permission is hereby granted, free of charge, to any person obtaining a + * copy of this software and associated documentation files (the + * "Software"), to deal in the Software without restriction, including + * without limitation the rights to use, copy, modify, merge, publish, + * distribute, sub license, and/or sell copies of the Software, and to + * permit persons to whom the Software is furnished to do so, subject to + * the following conditions: + * + * The above copyright notice and this permission notice (including the + * next paragraph) shall be included in all copies or substantial portions + * of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS + * OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF + * MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT. + * IN NO EVENT SHALL PRECISION INSIGHT AND/OR ITS SUPPLIERS BE LIABLE FOR + * ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, + * TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE + * SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE. + */ + +#include <GL/gl.h> +#include "glapi.h" +#include "glapitable.h" + + +#if !(defined(USE_X86_ASM) || defined(USE_SPARC_ASM)) + +#define KEYWORD1 + +#define KEYWORD2 + +#define NAME(func) gl##func + +#define DISPATCH(func, args, msg) \ + const struct _glapi_table *dispatch; \ + dispatch = _glapi_Dispatch ? _glapi_Dispatch : _glapi_get_dispatch();\ + (dispatch->func) args + +#define RETURN_DISPATCH(func, args, msg) \ + const struct _glapi_table *dispatch; \ + dispatch = _glapi_Dispatch ? _glapi_Dispatch : _glapi_get_dispatch();\ + return (dispatch->func) args + + +#include "glapitemp.h" + +#endif /* USE_X86_ASM */ diff --git a/src/glx/mini/dri.h b/src/glx/mini/dri.h new file mode 100644 index 0000000000..71f9a1acbf --- /dev/null +++ b/src/glx/mini/dri.h @@ -0,0 +1,124 @@ +/** + * \file miniglxP.h + * \brief Define replacements for some X data types and define the DRI-related + * data structures. + * + * \note Cut down version of glxclient.h. + * + */ + +#ifndef _dri_h_ +#define _dri_h_ + +#include "driver.h" + +typedef struct __DRIscreenRec __DRIscreen; /**< \copydoc __DRIscreenRec */ +typedef struct __DRIcontextRec __DRIcontext; /**< \copydoc __DRIcontextRec */ +typedef struct __DRIdrawableRec __DRIdrawable; /**< \copydoc __DRIdrawableRec */ + +/** + * \brief Screen dependent methods. + * + * This structure is initialized during the MiniGLXDisplayRec::createScreen + * call. + */ +struct __DRIscreenRec { + /** + * \brief Method to destroy the private DRI screen data. + */ + void (*destroyScreen)(__DRIscreen *screen); + + /** + * \brief Method to create the private DRI context data and initialize the + * context dependent methods. + */ + void *(*createContext)(__DRIscreen *screen, const __GLcontextModes *glVisual, + void *sharedPrivate); + /** + * \brief Method to create the private DRI drawable data and initialize the + * drawable dependent methods. + */ + void *(*createDrawable)(__DRIscreen *screen, + int width, int height, int index, + const __GLcontextModes *glVisual); + + /* + * XXX in the future, implement this: + void *(*createPBuffer)(Display *dpy, int scrn, GLXPbuffer pbuffer, + GLXFBConfig config, __DRIdrawable *pdraw); + */ + + /** + * \brief Opaque pointer to private per screen direct rendering data. + * + * \c NULL if direct rendering is not supported on this screen.
