A few of my programs were using the client string in addition to the
main extensions string to see if a feature was present. Correct this to
only check for the currently available and working extensions.
st/egl: Add get_param to native display interface.
get_param can be used to query the parameters of a native display.
There is only NATIVE_PARAM_USE_NATIVE_BUFFER right now. It queries
whether the window/pixmap surfaces use the native buffers instead of
private buffers.
st/egl: Add event support to the native display interface.
There is only invalid_surface event right now. When EGL receives the
event, it sets the force_validate flag of the context binding to the
surface. This helps skip an unnecessary check.
Revert "mesa: Remove pointless comparison of unsigned integer with a negative constant."
This reverts commit a05fdbcb71.
Removing the comparison is wrong. The comparison with -1 should be changed
to another value (probably PROGRAM_UNDEFINED) along with another
change in the shader assembler.
Conflicts:
src/mesa/shader/prog_execute.c
Shaves 60k off the driver from removing the broken spans code. This
means we now require 2.6.29, which seems fair given that it's a year
old and we've removed support for non-KMS already in the last release
of 2D.
gallivm: implement texture border color, plus tweaks to some wrap modes
The progs/test/texwrap demo looks pretty good, but there are still some
tiny differences from softpipe. There may be a sub-pixel texcoord
interpolation error somewhere.
There's some room for optimization. Many of the wrap modes compute
intermediate values that are constant for the texture size (see the
min/max values). These could be computed earlier and stored somewhere
for later use.
Wine tends to pessimistically use ~0 for its max index, but r300s
only can go up to 2^24-1, causing the kernel checker to freak out.
Civ4 is marginally improved now. Still crashes, but not as bad.
gallivm: rework and implement more texture wrap modes
All the texture wrap modes are now implemented for linear and nearest
sampling.
However, texture border color is not yet supported so some wrap modes
will produce int coords outside the texture bounds. We'll get garbage
values insted of the texture border color for now.
gallivm: clarify unsigned vs. signed integer type construction
The lp_int_type() function was creating an unsigned type. So rename
that function to lp_uint_type() and create new lp_int_type() that
creates a signed type.
This now passes piglit testcases, and shows performance improvements
on openarena. Blit-heavy apps may see degradation, but the
expectation is that the common case of 3D rendering will see
significant wins.
This regresses gen-teximage on my 855, and no piglit tests on my 945.
The break in the __DRI_ATTRIB_RENDER_TYPE case was accidentally
removed in commit 5cf2c5851b. This puts
it back.
