2005-02-23With Savage DRM version 2.3.x or later use event counters for textureFelix Kuehling
heap aging, similar to the way it's done in the i810 and i855 drivers. This avoids idling the engine on every texture upload.
2005-02-05Disable vertex DMA on SuperSavages.Felix Kuehling
2005-02-05- Fixed scissor rectangle not moving with the window (Xorg bug #1731).Felix Kuehling
- Flush buffered primitives before changing scissors. - Require Savage DRM version 2.1.0, so that the broken single-cliprect code can finally rest in peace. - Removed some more dead code.
2005-02-04Added an option texture_heaps that allows selecting which texture heapsFelix Kuehling
will be used. Implemented this option in the Savage driver. On my ProSavageDDR uploads to AGP memory are about 1.5 times as fast as uploads to card memory. On non-IGP hardware the difference may be even bigger. Now mplayer -gl is getting really usable.
2005-02-02Check for heap == NULL before driSetTextureSwapCounterLocation.Felix Kuehling
2005-01-31Bug #2428: #ifdef GLX_DIRECT_RENDERING in DRI drivers is pointless.Adam Jackson
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
2005-01-23My 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.
2005-01-13Make 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.
2005-01-08Added state debugging option (SAVAGE_DEBUG=state).Felix Kuehling
Fixed: Use savageEmitChangedRegs instead of savageEmitContiguousRegs for emitting Savage4.
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).
2005-01-01Removed 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.
2004-12-17Made 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.
2004-12-15Moved some code from savageCreateContext to savageInitDriver, where itFelix Kuehling
belongs. Removed some obviously useless code. Fixed computation of MaxTextureLevels.
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.
2004-10-08Apply Eric's stencil wrap patch (Eric Anholt)Alex Deucher
2004-10-02added support for GL_ARB_draw_buffersBrian Paul
2004-08-22Converted the Savage driver to the new DRI interface and enabled compilationFelix Kuehling
in the Mesa tree.
2004-06-03Open/Close FullScreen die. unichrome and savage implemented, code is ifdef'd outJon Smirl
2004-03-24Missing in last commit.Felix Kuehling
2004-03-21ctx->Const.MaxTextureLevels is not the highest mipmap level but the numberFelix Kuehling
> of levels, including 0.
2004-03-21Improved MaxTextureLevel computation to take the nr. of tex units and bothFelix Kuehling
texture heaps into account.
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.
2004-03-07Fixed two small problems in the vertex setup.Felix Kuehling
- make sure that vertex setup is initialized - Savage seems to need the W coordinate for smooth shading
2004-02-29Reorganized hardware state data structures and state emission. Don't trackFelix Kuehling
which registers changed in all the functions that change the state. Instead check which registers changed in the end when the hardware state is updated. Tried to avoid cosmetic (whitespace) changes in this commit.
2004-02-26Set ctx->Const.MaxTexture[Image/Coord]Units correctly. Fixes corruption in q3.Felix Kuehling
2004-02-26Converted vertex setup to use t_vertex.[ch].Felix Kuehling
2004-02-25Call _tnl_allow_pixel/vertex_fog in savageCreateContext. (Brian Paul)Felix Kuehling
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.
