Fix the reversed GLX_VENDOR_ABI_GET_MAJOR_VERSION and
GLX_VENDOR_ABI_GET_MINOR_VERSION macros.
Add individual #defines for libglvnd's major and minor version for better
readability.
|
|
Updates to libGLX vendor library interface.
|
|
Fix the return type in the __GLX_MAIN_PROTO macro.
In GLX_dummy.c, check the major and minor version numbers like a real vendor
library might. In addition, GLX_dummy.c now keeps a pointer to the
__GLXapiExports struct instead of a copy of it.
|
|
build: use system glproto headers
|
|
Added the function pointers for entrypoint rewriting as members of
__GLXapiImports, instead of using a separate __GLdispatchPatchCallbacks
pointer.
Moved the __GLdispatchPatchCallbacks struct to GLdispatch.h.
|
|
__glx_Main now takes a pointer to the __GLXapiImports struct and fills it in.
The __GLXapiImports struct is now allocated and zeroed by libGLX. This makes it
possible to add an optional element to the end of the struct without breaking
backward compatibility.
|
|
Removed the vendorID and vendorName parameters from the __glx_Main function,
since neither one is useful to a vendor.
Instead, __glx_Main now takes the __GLXvendorInfo pointer as a parameter. We
can use that to look up any additional per-vendor information that might be
added in the future.
|
|
The version number for the libGLX vendor library interface now uses a major and
minor version number in the high- and low-order 16 bits.
The major version is used for changes that break existing vendor libraries, and
the minor version is for changes where existing vendor libraries will still
work.

Removed the distinction between TSD and TLS stubs, since that doesn't matter to
a vendor library. There's now a single type for the x86 stubs and a single type
for the x86-64 stubs.
Added a separate type enum for normal ARM and thumb stubs. As with x86, there's
no distinction between TLS and TSD.
Changed the __GLDISPATCH_STUB_PURE_C enum to a more generic
__GLDISPATCH_STUB_UNKNOWN.
Also removed the internal ENTRY_* enums and changed everything to use the
__GLDISPATCH_STUB_* enums instead.
|
|
Renamed __GLdispatchPatchCallbacks::checkPatchSupported to isPatchSupported,
and renamed __GLXapiImports::checkSupportsScreen to isScreenSupported.
|
|
Changed vendorFromContext, vendorFromFBConfig, and vendorFromDrawable to return
the vendor pointer as its return value instead of using a pointer.
Returning by pointer was necessary when the functions would also return a
screen number. But, GLX objects are now associated directly with a vendor,
not with any particular screen or display.
|
|
Removed addScreenVisualMapping, removeScreenVisualMapping, and vendorFromVisual
from __GLXapiExports.
The XVisualInfo to vendor mapping is a no-op, since it just uses the screen number
to select a vendor.
It might be useful in the future at some point to provide a mechanism for
selecting between multiple vendors on a single X screen, but such an option
would more likely be used with the GLXFBConfig-based functions, not with the
XVisualInfo-based ones.
|
|
The addVendorContextMapping, addVendorFBConfigMapping, and
addVendorDrawableMapping functions in __GLXapiExports now return an int to
indicate success or failure.
Updated the various GLX functions so that they will deal with those failures.
In the case of context and drawable creations functions, it will call back into
the vendor library to destroy the object before returning.
|
|
The threadAttach callback is used so that a vendor library can go through any
thread initialization it needs to in order to deal with any later OpenGL calls.
This allows a vendor library to work around broken applications that try to
call OpenGL functions without a current context.

As pointed out with commit d5bc0866a8c "Check for glproto in
configure.ac" we want to rely on the upstream/distribution provided
package. Thus lets remove the in-tree copy.
Also make sure we use the headers (add the missing CFLAGS).

The macros in lkdhash.h now just use the __glvndPthreadFuncs table, instead of
taking a GLVNDPthreadFuncs parameter.

glxmd.h was removed in a previous commit, but it's used from glxproto.h.
|
|
Removed several header files that were copied from Mesa but aren't used in
libglvnd.
Removed everything under src/arch, also copied from Mesa but unused.
|
|
Two header files (libglxabi.h and GLdispatchABI.h) are public -- intended to be
used by vendor libraries, while the other headers are all internal to libglvnd.
Move the public header files to a new directory, include/glvnd.
Add a makefile so that the public headers are installed by make install.

- Add a config check for ((constructor)) and ((destructor)) funciton
attributes.
- Add missing GL/glxmd.h header.
- For sufficiently old gcc versions, revert to inline asm
implementations of Atomic{Increment,Swap,CompareAndSwap}()
- Add a local implementation of asprintf.
- entry_x86_tsd.h: Add missing cast to (char *) in entry_get_public
- glvnd_pthread.[ch]: Only use pthread_rwlock_t if it's available, and fall
back to pthread_mutex_t otherwise.
- trace.c: Add missing _GNU_SOURCE define
- uthash.h: Fix a -Wcast-qual warning
- x11glvndclient.c: Fix a -Wcast-qual warning by using a writable
array for storing the XGLV_EXTENSION_NAME
Based on a patch by Brian Nguyen.

This macro frees all entries in a locked hash table, and either
re-initializes the table's lock for fork recovery, or destroys the
lock, in which case the hash table is fully torn down and must be
re-initialized before it can be used.

Also remove a duplicate STATIC_ASSERT() macro from include/compiler.h.

This typedef is already defined in GL/glext.h and GLES/gl.h; including
this redundant typedef may lead to build errors.

This is a simple wrapper around uthash which simplifies read/write
locking around hashtables used by libGLX.

This is a copy of list.h from xserver commit
74469895e39fa38337f59edd64c4031ab9bb51d8, modified to prevent namespace
clashes with list.h.
