Currently used by the i915tex driver. 26 Other DRI drivers will be updated to use the new memory manager in 27 coming months. 28 29 To use the new driver you'll need the most recent DRM library and 30 drivers (version 2.2 or later) and a recent xf86-video-intel driver 31 module from X.org. 32 33 New features resulting from this work include: 34 35 - EXT_framebuffer_objects, render to texture 36 - ARB_pixel_buffer_objects 37 - Accelerated CopyTexSubimage, DrawPixels, ReadPixels, CopyPixels 38 - Accelerated texture uploads from pixel buffer objects 39 - Potentially texturing directly from the pixel buffer object (zero 40 copy texturing). 41 42- New Intel i965 DRI driver 43- New ``minstall`` script to replace normal install program 44- Faster fragment program execution in software 45- Added (or fixed) support for 46 `GLX_SGI_make_current_read <https://www.khronos.org/registry/OpenGL/extensions/SGI/GLX_SGI_make_current_read.txt>`__ 47 to the following drivers: 48 49 - radeon 50 - savage 51 - mga 52 - tdfx 53 54- Added support for ARB_occlusion_query to the tdfx driver (Ian 55 Romanick). 56 57Bug fixes 58--------- 59 60- fixed invalid memory read while rendering textured points (bug 8320) 61- fixed problems with freebsd-dri configuration (bug 8344) 62- Mesa's fake glxGetCurrentContext() wasn't thread-aware 63- OPTION NV_position_invariant didn't work in NV vertex programs 64- glDrawPixels into a user-created framebuffer object could crash Xlib 65 driver 66- Line clipping was broken in some circumstances 67- fragment.fogcoord register didn't always contain the correct value 68- RGBA logicops didn't work reliably in some DRI drivers 69- Fixed broken RGBA LogicOps in Intel DRI drivers 70- Fixed some fragment program bugs in Intel i915 DRI driver 71- Fixed glGetVertexAttribfvARB bug 8883 72- Implemented glGetUniform[fi]vARB() functions 73- Fixed glDrawPixels(GL_COLOR_INDEX, GL_BITMAP) segfault (bug 9044) 74- Fixed some gluBuild2DMipmaps() bugs (Greg McGarragh) 75- Fixed broken "mgl" name mangling 76- Indirect rending was broken for glMap\* functions (bug 8899) 77 78Internal code changes 79--------------------- 80 81- The device driver functions ResizeBuffers and GetBufferSize have been 82 decprecated. 83- OpenGL 2.0 and 2.1 support is nearly done. We need to do quite a bit 84 more testing of the shading language functions. 85 86To Do (someday) items 87--------------------- 88 89- Switch to freeglut 90- Increase MAX_DRAWBUFFERS 91- Fix linux-glide target/driver. 92- Improved lambda and derivative calculation for frag progs. 93 94Driver Status 95------------- 96 97:: 98 99 Driver Status 100 ---------------------- ---------------------- 101 DRI drivers varies with the driver 102 XMesa/GLX (on Xlib) implements OpenGL 1.5 103 OSMesa (off-screen) implements OpenGL 1.5 104 Glide (3dfx Voodoo1/2) implements OpenGL 1.3 105 SVGA implements OpenGL 1.3 106 Wind River UGL implements OpenGL 1.3 107 Windows/Win32 implements OpenGL 1.5 108 DJGPP implements OpenGL 1.5 109 GGI implements OpenGL 1.3 110 BeOS implements OpenGL 1.5 111 Allegro needs updating 112 D3D needs updating 113
