Was only used to get the PUBLIC/USED macros.
Also, replace "GL_FALSE" with "False" in a couple places.
|
|
Return Bool instead of GLboolean to match other functions.
Define PUBLIC/USED macros locally.

A couple of those lines of debug printfs I deleted weren't actually debug
printfs.

Fixes bug 15477

Respect the user's choice of shell when running mklib rather than always
using /bin/sh.

this disables accelerated DRI and fallbacks to client-side software rendering.
compile-tested only.

Add #include "glheader.h" for definition of __builtin_expect for compilers
that don't support it.

caveats:
- does not work with old (i.e. libGLcore) xserver:
- made unbindContext a noop
- extensions:
GLX_SGI_make_current_read
GLX_EXT_texture_from_pixmap
GLX_MESA_copy_sub_buffer

This reverts commit 7688791fc52f116eea421fda1d17aba5cf10977b, and takes
us back to generating the glapi files straight into the xserver tree.
Conflicts:
src/glx/x11/indirect_size_get.c

Since the only valid consumer of the DRI drivers is the X.Org xserver,
this changes the default DRI driver directory to match xorg-server:
${libdir}/dri. The old default of /usr/X11R6/modules/dri was wrong for
nearly all current systems.
|
|
Mostly some pedantic changes such that `make clean' always ignores
errors. Also changed the top clean target to do the `touch
configs/current' dance instead of realclean.
|
|
Consistently cleanup the depend.bak files created by makedepend. Also,
realclean has been changed to use a single find command, which speeds it
up considerably.
|
|
When changing directories and running a sub-make, ensure that both the
cd and make commands propagate errors to the parent make.

Fixes compiz with direct rendering when both GLX_TEXTURE_2D_EXT and
GLX_TEXTURE_RECTANGLE_EXT are supported for a GLXPixmap and the
application didn't specify the texture target as a GLX drawable attribute
when creating the GLX drawable.

Thanks to Adam Jackson for pointing it out.

Add DRI2 direct rendering support to libGL and add DRI2 client side
protocol code. Extend the GLX 1.3 create drawable functions in
glx_pbuffer.c to call into the DRI driver when possible.
Introduce __DRIconfig, opaque struct that represents a DRI driver
configuration. Get's rid of the open coded __GLcontextModes in the
DRI driver interface and the context modes create and destroy
functions that the loader was requires to provide. glcore.h is no
longer part of the DRI driver interface. The DRI config is GL binding
agnostic, that is, not specific to GLX, EGL or other bindings.
The core API is now also an extension, and the driver exports a list
of extensions as the symbol __driDriverExtensions, which the loader
must dlsym() for. The list of extension will always include the DRI
core extension, which allows creating and manipulating DRI screens,
drawables and contexts. The DRI legacy extension, when available,
provides alternative entry points for creating the DRI objects that
work with the XF86DRI infrastructure.
Change DRI2 client code to not use drm drawables or contexts. We
never used drm_drawable_t's and the only use for drm_context_t was as
a unique identifier when taking the lock. We now just allocate a
unique lock ID out of the DRILock sarea block. Once we get rid of the
lock entirely, we can drop this hack.
Change the interface between dri_util.c and the drivers, so that the
drivers now export the DriverAPI struct as driDriverAPI instead of the
InitScreen entry point. This lets us avoid dlsym()'ing for the DRI2
init screen function to see if DRI2 is supported by the driver.

to check whether oldGC is used for direct rendering in
function MakeContextCurrent. However it is possible
oldGC->driContext is already freed. fix bug #14926.
