2005-01-29* Fixed uploading of textures of certain sizes.Felix Kuehling
* When glTexSubImageND is used, track the set of changed tiles in a bit vector and upload only dirty tiles later. This should improve the performance of dynamic light maps and gl movie player plugins. * Renamed debug item "lru" to "tex". Indicate which levels are uploaded completely or partially.
2005-01-24Converted the Savage texture management to use Ian's common texmem code.Felix Kuehling
2005-01-23Fixed initialization of draw destination to front buffer on singleFelix Kuehling
buffered visuals. Also don't change span draw/read buffers in savageDDDrawBuffer. Now glean's polygon offset test works (and PASSes with fixed point depth buffer) with single buffered visuals without winding up in an infinite loop.
2005-01-23My last attempt to fix polygon offsets with the reversed viewport depthFelix Kuehling
range used by the savage driver by negating ctx->MRD broke polygon offsets with software fallbacks. This one adds a REVERSE_DEPTH parameter to t_dd_tritmp.h (defaults to 0) that allows reversing polygon offsets for hardware rendering but not for software fallbacks. For software fallbacks depth values are reversed after polygon offsets have been applied by the depth span functions.
2005-01-22Fixed polygon offset with reversed viewport depth range.Felix Kuehling
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
2005-01-20* Added options for disabling the fast path (render stage) and vertex DMAFelix Kuehling
* Fixed disabling of the render stage * Added debug output for per-primitive fallbacks * Bumped driver date
2005-01-20Added support for ELTS to the _savage_render_stage. Requires at leastFelix Kuehling
Savage DRM version 2.2.0. Otherwise the render stage is disabled.
2005-01-16Added a fast path for emitting unclipped primitives directly to aFelix Kuehling
vertex buffer. ELTS are not supported yet (missing functionality in the DRM). You need at least Savage DRM version 2.1.3, which fixes a bug that screwed up triangle fans and strips. Moved the texture normalization stage to savagerender.c.
2005-01-15Converted to use spantmp2.h.Felix Kuehling
2005-01-13Make sure DMA buffers are released in savageDestroyContext. UsuallyFelix Kuehling
the DRM would reclaim DMA buffers, but if one process creates and destroys many contexts it can still run out of DMA buffers.
2005-01-10Fixes to cope with the lack of AGP textures. This is all that's neededFelix Kuehling
to support PCI Savages on the Mesa side. Bumped driver date.
2005-01-08* Flush and wait in per-primitive fallback functions. Fixes flickeringFelix Kuehling
stars in glplanet. * Refactored vertex format choosing code. Improved the Savage4 version to choose a format suitable for DMA (size = 32bytes) whenever possible.
2005-01-08Added state debugging option (SAVAGE_DEBUG=state).Felix Kuehling
Fixed: Use savageEmitChangedRegs instead of savageEmitContiguousRegs for emitting Savage4.
2005-01-07Fixed: ptex drawing functions were overridden with standard drawingFelix Kuehling
functions if ANY_RASTER_FLAGS|ANY_FALLBACK_FLAGS were set.
2005-01-05* Fixed handling of scissorsFelix Kuehling
* Only set scissor regs directly if drmMinor < 1 * Don't set texaddr to 0 when a texture unit is disabled. That would trigger the tightened texture state check in the DRM if the texaddr and texdesc registers were not emitted atomically.
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.
2005-01-01Removed all direct hardware access (MMIO, BCI) from the Savage DRIFelix Kuehling
driver. It uses the new DRM version 2.0.x now, which has just been committed to DRM CVS.
2004-12-23Simplified and optimized _savage_texnorm_stage.Felix Kuehling
2004-12-22Enabled hardware rendering of 1D textures. No need for a software fallback.Felix Kuehling
2004-12-22- Fake projective textures on a single texture unit. A fallback is onlyFelix Kuehling
needed if a second texture unit is enabled. - Also worked around an application bug in Chromium B.S.U.: it sends 3D texture coordinates while only a 2D texture is enabled. This used to trigger a PTEX fallback. Now the 3rd coordinate is just ignored. - Fixed the _savage_texnorm_stage to never normalize homogenous texture coordinates.
2004-12-17Made debugging output controllable via environment variableFelix Kuehling
SAVAGE_DEBUG. Added fallback debugs. Added no_rast option to disable hardware rasterization (everything as software fallback).
2004-12-17Added a TNL pipeline stage that normalizes texture coordinates as aFelix Kuehling
workaround for bad Savage hardware interpolation of big texture coordinates.
2004-12-16Also PUBLICize the config option tableAdam Jackson
2004-12-15Mark __driCreateNewScreen PUBLICAdam Jackson
2004-12-15Added configuration support to the Savage driver. Three options areFelix Kuehling
supported so far.
2004-12-15Fixed GL_CLAM_TO_EDGE. It's not supported in hardware. Use GL_CLAMPFelix Kuehling
instead of GL_REPEAT.
2004-12-15Fixed initialization of some stencil-related S4 registers, which wasFelix Kuehling
misplaced in savageDDInitState_s3d, where was overwriting completely unrelated S3D registers with garbage.
2004-12-15Moved some code from savageCreateContext to savageInitDriver, where itFelix Kuehling
belongs. Removed some obviously useless code. Fixed computation of MaxTextureLevels.
2004-12-15Fixed some missing uint8_t -> u_int8_t.Felix Kuehling
2004-12-14uint*t -> u_int*tAlan Hourihane
2004-11-27Remove _mesa_ResizeBuffersMESA() call from _mesa_set_viewport().Brian Paul
Now, the driver's Viewport routine should call _mesa_ResizeBuffersMESA() if necessary. Cleaned up code related to GLframebuffer width/height initialization. Set initial viewport/scissor params in _mesa_make_current2(), instead of in the drivers' MakeCurrent functions.

- Don't lock in savageDDUpdateStatte, don't call savageEmitHwStateLocked - Need to grab the lock for texture uploads now - New SAVAGE_NEW_CULL bit in new_state to make sure that culling state and raster_primitive are not examined at the wrong times.
2004-03-24Make sure hardware culling is disabled for unfilled primitives,Felix Kuehling
