2005-05-04Major check-in of changes for GL_EXT_framebuffer_object extension.Brian Paul
Main driver impacts: - new code for creating the Mesa GLframebuffer - new span/pixel read/write code Some drivers not yet updated/tested.
2005-04-21Fixed some suspicious pointer casts that caused lots ofFelix Kuehling
compile-time-warnings on x86-64. Not tested on x86-64 yet, but a good thing in general, so I'm giving up waiting for feedback. See also https://bugs.freedesktop.org/show_bug.cgi?id=2924.
2005-01-21Small cleanup:Felix Kuehling
* Remove some unused (mostly empty) functions * Added context parameter to WAIT_IDLE_EMPTY[_LOCKED] for consistency * Added debug messages to WAIT_IDLE_EMPTY[_LOCKED] * Don't flush empty command buffers
2005-01-15Converted to use spantmp2.h.Felix Kuehling
2005-01-03Added support for floating point depth buffers on Savage4-basedFelix Kuehling
hardware. By also reversing the depth range this can compensate the loss of accuracy of far objects caused by the projective transformation. Software fallbacks work but are slightly slower since floats in a custom (non IEEE) format have to be encoded and decoded. I havn't done anything about polygon offsets yet. There doesn't seem to be an easy way do get it right except making the offset unit as big as the lowest resolution of depth values. For now float depth is disabled by default but can be enabled through driconf (though I have seen only positive effects so far).
2005-01-02Improved the performance of software fallbacks by not waiting for idleFelix Kuehling
in every single span function. Instead flush and wait in the SpanRenderStart hook and in wrappers around _swrast_Copy/Draw/ReadPixels. Misc. cleanups in savagespan.c while I'm there.
2004-10-08Apply Eric's stencil wrap patch (Eric Anholt)Alex Deucher
2004-03-21Implemented support for software-based AUX color buffers.Brian Paul
Only available with Xlib driver for now. Assorted clean-ups related to Draw/ReadBuffer(). Renamed FRONT_LEFT_BIT -> DD_FRONT_LEFT_BIT, etc.
2004-02-22Imported the Savage DRI driver from the savage-2-0-0-branch of DRI CVSFelix Kuehling
with modifications to make it work with current Mesa 6.
