* gallium: use simple color pass-through fragment shader if textures don't existBrian Paul2008-04-252-2/+30
| | | | | | | If we run out of texture memory we may not have the texture needed by the fragment shader. If this happens, plug in a color passthrough shader. So instead of crashing, we just don't see the texture. GL_OUT_OF_MEMORY is raised, of course.

|
* gallium: use util_draw_vertex_buffer() instead of st_draw_vertices()Brian Paul2008-04-251-24/+70
|
* gallium: fix the compressed texture hack in st_texture_image_copy()Brian Paul2008-04-251-3/+2
| | | | | Actually, the hack is still there and needs to be revisited, but I get a bit further with compressed textures now.
* gallium: Use util_blit_pixels() for glCopyTexSubImage when appropriate.Michel Dänzer2008-04-251-14/+23
|
* gallium: Tell the driver the texture is updated when we finish rendering to it.Michel Dänzer2008-04-251-0/+4

* gallium: fix an edgeflags crashBrian Paul2008-04-241-1/+5
|
* gallium: initial edgeflags codeBrian Paul2008-04-241-1/+59
|
* gallium: disable the bitmap/texcoord biasBrian Paul2008-04-241-1/+1
| | | | Doesn't seem to be needed after fixing the float->int conversion problem.
* gallium: use cso_destroy_vertex/fragment_shader() functionsBrian Paul2008-04-245-13/+18
| | | | | Also, rearrange the st_destroy_context() code a bit to prevent some invalid/NULL ptr derefs during tear-down.
* gallium: Initial support for pixel formats with unused storage components.Michel Dänzer2008-04-241-0/+4
| | | | | Also clarify that RGB formats with no (used) alpha component are treated as having alpha = 1.0.
* gallium: fix some bitmap frag shader issuesBrian Paul2008-04-224-34/+62
| | | | | If texturing happens to be enabled when glBitmap() is called, need to be careful about choosing a sampler unit, etc.
* gallium: don't set buffer status to undefined in display_front_buffer()Brian Paul2008-04-221-0/+2
|
* gallium: st_translate_fragment_program() is void nowBrian Paul2008-04-222-5/+2
| | | | The return value was never used.
* gallium: How about restoring shaders instead of saving them again...Michel Dänzer2008-04-221-2/+2
|

|
* draw: move incoming vertex state into draw->ptKeith Whitwell2008-04-191-3/+3
| | | | | This state is effectively private to the vertex processing part of the draw module.
* draw: move some pipeline-specific code & state to draw_pipe.[ch]Keith Whitwell2008-04-192-2/+2

* gallium: get rid of unnecessary surface mappingBrian Paul2008-04-181-7/+5

|
* gallium: Flush render cache at the beginning of fallback_copy_texsubimage().Michel Dänzer2008-04-111-0/+3
| | | | It may get stale bits otherwise.
* gallium: fix readback of z16 valuesBrian Paul2008-04-101-1/+1
|
* gallium: more elaborate tracking of front color buffer stateBrian Paul2008-04-097-29/+54
| | | | | | | This fixes the case where the app calls SwapBuffers then calls glReadPixels to read the front color buffer. We now keep track of when the front buffer is a _logically_ copy of the back buffer (after SwapBuffers) and read from the back color buffer instead of the front.
* gallium: more flush/finish changesBrian Paul2008-04-091-30/+40
| | | | New, separate is_front_buffer_dirty() function.
* gallium: reorder funcsBrian Paul2008-04-091-11/+12
|
* gallium: call_flush_front_buffer() from st_glFinish()Brian Paul2008-04-091-0/+2
|
* gallium: fold st_gl_flush() into st_glFlush()Brian Paul2008-04-091-12/+5
|
* gallium: refactor code, new flush_front_buffer() functionBrian Paul2008-04-091-17/+25
|
* gallium: remove unneeded st->haveFramebufferSurfaces field.Brian Paul2008-04-093-13/+1
|
* gallium: check ctx->DrawBuffer before flushing bitmap cache.Brian Paul2008-04-071-29/+31
| | | | | During context unbind, we may not have a draw buffer. This fixes demos/tunnel2.c
* gallium: fix the texture case in default_deep_rgba_format()Brian Paul2008-04-071-1/+4
| | | | Fixes glean pixelFormat test
* gallium: slightly improved accum clear/mad operationsBrian Paul2008-04-071-33/+55
| | | | Instead of get/put_tile(), map the buffer and operate on values directly.
* gallium: accum buffer fixesBrian Paul2008-04-074-11/+84
| | | | | | | If the driver can't create a PIPE_FORMAT_R16G16B16A16_SNORM surface, create an accum surface using a shallower format and taller height. Since only the accum buffer code accesses the surface the actual format doesn't really matter, just that there's enough memory.
* gallium: remove stray commentBrian Paul2008-04-071-5/+1

* gallium: clean-up in st_renderbuffer_alloc_storage()Brian Paul2008-04-071-11/+16
