2008-07-03gallium: fix surface memleak in bitmap codeBrian Paul
Found w/ tunnel2.c demo.
2008-06-27gallium: Drop pipe_texture->cpp and pipe_surface->cpp.José Fonseca
The chars-per-pixel concept falls apart with compressed and yuv images, where more than one pixel are coded in a single data block.
2008-06-24mesa: More signed/unsigned float/integer fixes.José Fonseca
2008-06-17gallium: need to flush bitmap cache when raster color changesBrian Paul
2008-05-31mesa: Apply MSVC portability fixes from Alan Hourihane.José Fonseca
2008-05-27gallium: Always unreference bitmap cache texture before resetting the cache.Michel Dänzer
Fixes assertion failure with tunnel2 demo.
2008-05-20Merge branch 'gallium-0.1' into gallium-tex-surfacesBrian Paul
2008-05-20gallium: fix shader mem leakBrian Paul
2008-05-19gallium: remove dead codeBrian Paul
2008-05-19gallium: remove dead codeBrian Paul
2008-05-16gallium: fix glBitmap surface memleak in context tear-downBrian Paul
2008-05-08gallium: remove dead codeBrian Paul
2008-05-08gallium: no-op st_Bitmap() if width or height is zeroBrian Paul
2008-05-02gallium: Add texture usage flags, special-case allocation of display targetsKeith Whitwell
For many envirionments it's necessary to allocate display targets in a window-system friendly manner. Add facilities so that a driver can tell if a texture is likely to be used to generate a display surface and if use special allocation paths if necessary. Hook up softpipe to call into the winsys->surface_alloc_storage() routine in this case, though we probably want to change that interface slightly also.
2008-05-01gallium: tex surface checkpointKeith Whitwell
2008-04-30gallium: use the newer PIPE_FORMAT_x_UNORM format namesBrian Paul
2008-04-30gallium: use new buffer wrapper functions in p_inlines.hBrian Paul
This allows us to remove most of the direct references to winsys in the state tracker.
2008-04-30gallium: consolidate the bitmap->texel conversion codeBrian Paul
2008-04-30gallium: create a new texture each time we init/flush the bitmap cacheBrian Paul
2008-04-30gallium: simplify texture format selectionBrian Paul
2008-04-29gallium: flush pipe before updating bitmap textureBrian Paul
Fixes duplicated text bug in progs/tests/texwrap.c
2008-04-25gallium: remove unneeded st->bitmap_texcoord_biasBrian Paul
2008-04-24gallium: disable the bitmap/texcoord biasBrian Paul
Doesn't seem to be needed after fixing the float->int conversion problem.
2008-04-24gallium: use cso_destroy_vertex/fragment_shader() functionsBrian Paul
Also, rearrange the st_destroy_context() code a bit to prevent some invalid/NULL ptr derefs during tear-down.
2008-04-22gallium: fix some bitmap frag shader issuesBrian Paul
If texturing happens to be enabled when glBitmap() is called, need to be careful about choosing a sampler unit, etc.
2008-04-22gallium: How about restoring shaders instead of saving them again...Michel Dänzer
2008-04-21use cso fs/vs handle functionsKeith Whitwell
2008-04-21gallium: Use CSO cache for shaders.Michel Dänzer
2008-04-07gallium: check ctx->DrawBuffer before flushing bitmap cache.Brian Paul
During context unbind, we may not have a draw buffer. This fixes demos/tunnel2.c
2008-04-04gallium: make sure to set the SamplersUsed field for bitmap/drawpixels shadersBrian Paul
Also, make sure that field is copied/updated in the program clone and combine functions. Without this we weren't getting SAMP declarations in the TGSI shaders.
2008-04-03gallium: set rasterizer.gl_rasterization_rules = 1 in a few more placesBrian
2008-03-31gallium: used inverted bitmap texture to simplify the fragment shader.Brian
"Off" bits get stored as texel=0xff and "on" bits get stored as texel=0x0. Then use KIL -tmp to kill the off bits and keep the on bits. This shortens the fragment program by two instructions.
2008-03-31gallium: use cso_save/restore_sampler_textures() functionsBrian
2008-03-31gallium: set the bypass_vs flag nowBrian
The glBitmap vertex shader is a no-op, but we still have to specify it in order to convey the number of inputs/outputs.
2008-03-31gallium: turn on clipping for bitmapsBrian
Bitmaps can extend beyond window edges so we need to clip. Also, move some state atom vars to st_context to be a bit more efficient.
2008-03-28gallium: begin some bounding box code for bitmap cacheBrian
2008-03-28gallium: added an (int) cast in setup_bitmap_vertex_data() to fix a ↵Brian
signed/unsigned arithmetic problem Negative values became very large uints.
2008-03-28gallium: disable a debug hackBrian
2008-03-28gallium: implement a glBitmap cacheBrian
The bitmap cache attempts to accumulate a series of glBitmap calls in a buffer to effectively render a whole bunch of bitmaps at once. The cache can be disabled, if needed, by setting UseBitmapCache=GL_FALSE.
2008-03-27gallium: Update calls to the simple shader functionsBrian
2008-03-26gallium: need to call st_validate_state() in Bitmap()Brian Paul
2008-03-24gallium: free bitmap fragment shaders, misc clean-upBrian Paul
2008-03-24gallium: add missing cso_save_samplers() callBrian Paul
2008-03-21Refactor PBO validate/map code.Brian
We always need to do PBO validation, so do that in core Mesa before calling driv er routine. cherry-picked from Mesa/master.
2008-03-21gallium: implement PBO operations for glDraw/ReadPixels and glBitmapBrian Paul
At this time there are no optimizations for directly blitting between buffer objects and surfaces (always go through mappings). glean pbo test passes now
2008-03-20gallium: glBitmap code now separated from glDraw/CopyPixels codeBrian
