Currently used by the i915tex driver. Other DRI drivers will be updated to use the new memory manager in coming months. <br> To use the new driver you'll need the most recent DRM library and drivers (version 2.2 or later) and a recent xf86-video-intel driver module from X.org. <br> New features resulting from this work include: <ul> <li>EXT_framebuffer_objects, render to texture <li>ARB_pixel_buffer_objects <li>Accelerated CopyTexSubimage, DrawPixels, ReadPixels, CopyPixels <li>Accelerated texture uploads from pixel buffer objects <li>Potentially texturing directly from the pixel buffer object (zero copy texturing). </ul> <li>New Intel i965 DRI driver <li>New <code>minstall</code> script to replace normal install program <li>Faster fragment program execution in software <li>Added (or fixed) support for <a href="http://www.opengl.org/registry/specs/SGI/make_current_read.txt"> GLX_SGI_make_current_read</a> to the following drivers: <ul> <li>radeon</li> <li>savage</li> <li>mga</li> <li>tdfx</li> </ul> <li>Added support for ARB_occlusion_query to the tdfx driver (Ian Romanick).</li> </ul> <h2>Bug fixes</h2> <ul> <li>fixed invalid memory read while rendering textured points (bug 8320) <li>fixed problems with freebsd-dri configuration (bug 8344) <li>Mesa's fake glxGetCurrentContext() wasn't thread-aware <li>OPTION NV_position_invariant didn't work in NV vertex programs <li>glDrawPixels into a user-created framebuffer object could crash Xlib driver <li>Line clipping was broken in some circumstances <li>fragment.fogcoord register didn't always contain the correct value <li>RGBA logicops didn't work reliably in some DRI drivers <li>Fixed broken RGBA LogicOps in Intel DRI drivers <li>Fixed some fragment program bugs in Intel i915 DRI driver <li>Fixed glGetVertexAttribfvARB bug 8883 <li>Implemented glGetUniform[fi]vARB() functions <li>Fixed glDrawPixels(GL_COLOR_INDEX, GL_BITMAP) segfault (bug 9044) <li>Fixed some gluBuild2DMipmaps() bugs (Greg McGarragh) <li>Fixed broken "mgl" name mangling <li>Indirect rending was broken for glMap* functions (bug 8899) </ul> <h2>Internal code changes</h2> <ul> <li>The device driver functions ResizeBuffers and GetBufferSize have been decprecated. <li>OpenGL 2.0 and 2.1 support is nearly done. We need to do quite a bit more testing of the shading language functions. </ul> <h2>To Do (someday) items</h2> <ul> <li>Switch to freeglut <li>Increase MAX_DRAWBUFFERS <li>Fix linux-glide target/driver. <li>Improved lambda and derivative calculation for frag progs. </ul> <h2>Driver Status</h2> <pre> Driver Status ---------------------- ---------------------- DRI drivers varies with the driver XMesa/GLX (on Xlib) implements OpenGL 1.5 OSMesa (off-screen) implements OpenGL 1.5 Glide (3dfx Voodoo1/2) implements OpenGL 1.3 SVGA implements OpenGL 1.3 Wind River UGL implements OpenGL 1.3 Windows/Win32 implements OpenGL 1.5 DJGPP implements OpenGL 1.5 GGI implements OpenGL 1.3 BeOS implements OpenGL 1.5 Allegro needs updating D3D needs updating </pre> </body> </html>
