Not all is bad, but I'm afraid I'll have to throw the baby with the water
given they are all tied to together.

With an Intel 855GM handled by intel_drv, there's a crash with Gallium3D
enabled DRI driver for Intel i915 (--enable-gallium-intel).
The Gallium3D driver doesn't support the 855GM as expected by
intel_drv, it failed to open the screen and give an half
initialized screen structure to dri_destroy_option_cache():
optionCache.info is NULL, so it's crashing while trying
to free array content. This patch at least fix the crash in the function.
Here's some logs of the fixed version:

MAXWIDTH/HEIGHT were 2048 but the max texture size was 4096.
This caused a crash if a 4Kx4K texture was created and rendered to.
See comment about max framebuffer size in lp_scene.h.
Also added assertions to catch this inconsistancy in the future.

The code is correct. Tell Coverity that the fallthrough case is
intentional.

Will be needed later for transform feedback support.

Putting calls to util_format_init all over the codebase is infeasible.
Instead, half float tables are pregenerated, and the s3tc library is
loaded on demand.
I believe this is a solution that combines performance, cleanliness,
flexibility and portability.
|
|
This improves the code by making it more readable, and removes
special knowledge of S3TC and other formats from softpipe.
|
|
This changes the S3TC function pointers to be initialized to stubs
that load the S3TC library and then delegate to the real functions.
If the S3TC library fails to load, the function pointers are replaced
with a "nop" function.
The code is also changed to attempt to load the library only one time.c
Note that unlike checking for a flag, this method has no performance
cost at all.
The use of the "nop" functions also allows to avoid most checks, that
are only preserved when the function does non-trivial work.
|

|
|
This solution avoids the issue of how to run the initializers and
also allows those pages (and the parts of them in processor caches)
to be shared between multiple processes.
The drawback is slightly higher library size.
|
|
The swtich in egl_g3d_st_framebuffer_validate misses a break.
|
|
|
|
This moves eglut before EGL so that the symbols can be resolved.
|
|
Fixes MSVC build.
|
|
Needed to fetch static vertex attributes.
|
|
Switch from auto-init to explicit init for util_half per Brian Paul's
indication.
NOTE: this is probably broken because not enough things call util_format_init.
Will be fixed shortly

They apparently both declare the section, but #pragma data_seg
also puts all subsequent definitions in the section, which is
undesirable.
This should be the correct solution, and is actually used by the
reference I cited (but I forgot to do it in my code).
Untested, let me know if it doesn't work.
|
|
Sorry, forgout about that.

This reverts commit 950300eb255f0e3507bf2757d16c3b5bc8ff3471.
|
|
The Xlib demos were fixed to use $(X11_LIBS) so that configure could
detect the proper directory to link the library from, but this broke
the non-autoconf builds. Give X11_LIBS a default value to fallback on.

Gets rid of unnecessary delays on startup and compiler-specific hax.

NOTE: this commit will cause Gallium to fail to build on any compiler
except GCC, the Microsoft C compiler and compatible compilers that
claim to be one of those.
This commit removes the u_gctors.cpp mechanism, in favor of using
compiler-specific syntax to add global constructors from C files.
This solves the problem of u_gctors.o not being pulled from static
libraries and avoids using C++.
However, it needs compiler-specific support for every compiler.
The Microsoft C compiler support has not been tested.
