Move all the metaops to a dri_metaops file and port radeon/intel
to use the new common meta ops code.
|
|
RasterPos[2] is already sent through the window transform, which includes
DepthRange handling. So make DepthRange for the metaops a noop.
Fixes a failure in oglconform depthrange.c

We would have to build the program with the appropriate fog mode, and
also supply the fog coordinate if appropriate.
Bug #19413.

This is somewhat nasty, but we need to do Y-tiled depth for FBO support.
May help with corruption and hangs since enabling texture tiling, and
since switching depth textures to Y tiled.
Fixes piglit depthtex.c on 965.

Fixes oglconform zbfunc.c and pxtrans-cidraw.c, at least.

Make this be its own function for setup/teardown of the binding of these
texcoords. No performance difference in the engine demo (I just felt dirty
not using a VBO for this), and I think it should be more resilient to
interference from current GL state.

Found while debugging cairo-gl.

When we use the do_blit_bitmap() function, it seems the fragment Z is always
1.0. If depth testing is on, that means that bitmap fragments are often
occluded by other rendering. So, the bitmap doesn't appear even if
rasterpos.Z==0.
The fix is to use the intel_texture_bitmap() path when depth testing is on.
Also, fix the incorrect Z coordinate. It needs to be an NDC value in [-1,1].

The DrawPixels path was missing glViewport care, so blender's toolbar icons
would go to the wrong places.
Bug #19118.
|
|
This lets us avoid software fallbacks when clients forget to turn some state
off (engine demo) or just do crazy things to test conformance (OGLC).
This should probably be brought into mesa generic code so other drivers can
make use of it.

Bug #18914. Fixes fbo_firecube hang due to drawing outside the FBO bounds.
Thanks to Pierre Willenbrock for debugging the issue.

Most of these were to ensure that caches got synchronized between 2d (or meta)
rendering and later use of the target as a source, such as for texture
miptree setup. Those are replaced with intel_batchbuffer_emit_mi_flush(),
which just drops an MI_FLUSH. Most of the remainder were to ensure that
REFERENCES_CLIPRECTS batchbuffers got flushed before the lock was dropped.
Those are now replaced by automatically flushing those when dropping the lock.

Mesa demos tend to leave blending on but in GL_ONE/GL_ZERO, or
GL_SRC_ALPHA/GL_ONE_MINUS_SRC_ALPHA with a source alpha of 1.0.
