Remove some unneeded fields. Rename some function parameters.
|
|
Rename some structs and fields to be more consistant with the rest of mesa.

Rendering and textures are limited to 8kx8k, but mesa limits things to
4kx4k, and magic guard band stuff may break on 8kx8k drawing. This is safe
though, and makes compiz work on bigger screens.

Fixes failed assertion / segfault for particular proxy texture tests.

Tries to use either GLX_MESA_swap_control or GLX_SGI_video_sync to
detect whether the display is synchronized to the vertical blank. If
it detects this, a message will be printed. HOPEFULLY this will
prevent some of the bug reports such as "glxgears only gets 59.7fps.
What's wrong with my driver?"

adjust_buffer_object_ref_counts()
Fixes bug 19835. However, a more elaborate fix should be implemented someday
which uses proper reference counting for gl_array_object.
|
|
This is a 10% win on the ever-important glxgears not-a-benchmark.
|
|
This saves an inadvertent round-trip to the X Server on DrawBuffers, which was
hurting some metaops.
|

We can support any combination of (a8r8g8b8, x8r8g8b8, r5g6b5) x (z0,z24,z24s8)
on either class of chipsets. The only restriction is no mixing bpp when also
mixing tiling. This shouldn't be occurring currently.

On newer GCC releases, the compiler's headers have been split between
the include and include-fixed directories. Add both if the directories
exist.

This is part of GL_EXT_framebuffer_blit and GL_ARB_framebuffer_obbject.

Anytime we're not rendering to the default/window FBO, need to invert
rendering, not just when rendering to a texture. Otherwise, if a FBO
consists of a mix of textures and renderbuffers the up/down orientation
was inconsistant.
Fixes shadowtex.c bad rendering.
|
|
When glTexImage() is called we need to re-validate any FBOs that point to
the texture (i.e. render-to-texture) since changing the texture's size/format
will effect FBO completeness.
We don't keep a list of all FBOs rendering into each texture (which would be
a bit messy) so we check all FBOs in existance. To optimize this, the
gl_texture_object->_RenderToTexture flag is used to avoid checking textures
that have never been used as renderbuffers. So, we only walk over all FBOs
(there's usually only a few) when glTexImage() modifies a RTT texture.
Fixes a bug seen in shadowtex.c when toggling packed depth/stencil mode.

Move the remaining extension string enables to intel_extensions.c.
Make sure that GL_NV_texture_env_combine4 is not enabled on i830.

Everyone should be using the newer/better ARB versions of these extensions.

Just to reinforce the understanding that an extended swizzle with 0 and 1
terms is possible there.
|
|
If the texture swizzle is not XYZW (no-op) add an extra MOV instruction
after the TEX instruction to rearrange the components.
|
|
|
|
|
|
Previously, "in-place" swizzles such as:
MOV t, t.xxyx;
were handled incorrectly. Fixed by splitting the one loop into two loops so we
get all the refs before assigning them (to avoid potential clobbering).
