Since the TNL is all done in software anyway, it should be the same to
the user who's probably using ARB_vertex_program otherwise, but gives them
a nicer programming environment.
|
|
This fixes potential heap trashing if the program of choice exceeds limits,
and fixes the native instructions limit being lower than what can be
used by valid programs.
|
|
Previously, we were doing it in the midst of the pipeline run, which gave
an opportunity to enable/disable fallbacks, which is certainly the wrong
time to be doing so. This manifested itself in a NULL dereference for PutRow
after transitioning out of a fallback during a run_pipeline in glean glsl1.
|
|
This reverts commit e7044d552c6d16389447880b8744a51de1cf0199. It
prevented the driver from ever recovering from a software fallback due
to a program error. The original bug it claimed to fix doesn't appear to
exist post-revert.
|
|
Previously, we'd go trashing the heap.
|
|
It's misleading to report things like the program having too many native
instructions as a Mesa implementation error, when the program may just be
too big for the hardware.

lim x->0 log(x) = -inf so -FLT_MAX is a better approximation than 0
for LG2(0).

This was redundant as drivers can just keep track of whether they are
inside a begin/end query pair. We want to add more query types later
and also support nested queries, none of which map well onto a flag like
this. No driver appeared to be using the flag.

Need to be careful with component ordering for MESA_FORMAT_RGB888
and MESA_FORMAT_RGBA8888.

Not used by any hardware driver. ARGB4444 and ARGB4444_REV remain.
|
|
Removed: MESA_FORMAT_RGBA, RGB, ALPHA, LUMINANCE, LUMINANCE_ALPHA, INTENSITY.

Now gl_texture_image::TexFormat is a simple MESA_FORMAT_x enum.
ctx->Driver.ChooseTexture format also returns a MESA_FORMAT_x.
gl_texture_format will go away next.

Once we've freed a miptree, we won't see any more state cache requests
that would hit the things that pointed at it until we've let the miptree
get released back into the BO cache to be reused. By leaving those
surface state and binding table pointers that pointed at it around, we
would end up with up to (500 * texture size) in memory uselessly consumed
by the state cache.

This feature corresponds to the Begin/End paradigm. Disabling this
feature also eliminates the use of GLvertexformat completely.

As shown in mfeatures.h, this allows users of dlist.h to work without
knowing if the feature is available.

As shown in mfeatures.h, this allows users of eval.h to work without
knowing if the feature is available.

It merges FEATURE_ARB_occlusion_query and FEATURE_EXT_timer_query, and
follows the feature conventions.

This allows the removal of AEcontext.

As shown in mfeatures.h, this allows users of drawpix.h to work

It is separated from FEATURE_drawpix and made to follow the feature
conventions.

Since sqrt() is basically implemented in terms of RSQ/RCP we'll do a
divide by zero if x=0 and wind up with unpredictable results.
Now use CMP instruction to test for x<=0 and return zero in that case.

Return GLX_RGBA_TYPE or GLX_COLOR_INDEX_TYPE.

These options can be used to force vertex/fragment shaders to be no-op
shaders (actually, simple pass-through shaders). For debug/test purposes.
