Thread-safety is no longer a TODO item. There are surely bugs to be
fixed though.
|
|
Lock the global mutex in _eglPreloadDrivers and _eglAllocScreenHandle.
Add comments to why certain pathes do not need locking.
|
|
This gives a simple access control to the display. It is potentially
slow, but a finer grained mutex can always be used in the future. The
benefit of this simple approach is that drivers need not to worry about
thread-safety.
|
|
Merge _eglNewDisplay and _eglLinkDisplay into _eglFindDisplay. Remove
unused _eglUnlinkDisplay.
|
|
A display may be shared by multiple threads. Add a mutex for access
control.
|
|
Use macros to record the status of the function call before returning.
This is the only way that eglGetError can return the status of the most
recent function call.
|
|
The error code denotes the success or failure of the most recent
function call. A call to _eglError should always update the error code.
|
|
Replace all uses of _EGL_DECLARE_* and _eglCheck* by _EGL_CHECK_*.
|
|
Add _EGL_CHECK_* which will replace _EGL_DECLARE_* for error checking.
Move _eglCheck* earlier in the file so that the macros and the functions
are grouped together.

Some nice speedups:
gears: 547 -> 597
isosurf: 83 -> 98
Others like gloss unchanged. Could do further work in this direction.

Parse extension tokens to track current state of extension enables.

|
The #extension directive should not effect which extension preprocessor
symbols are defined/undefined; only whether/how the compiler accepts
language features defined by the extension.

When a buffer invalidation event is received from the X server, the
"invalidate" hook of the DRI2 flush extension is executed: A generic
implementation (dri2InvalidateDrawable) is provided that just bumps
the "pStamp" sequence number in __DRIdrawableRec.
For old servers not supporting buffer invalidation events, the
invalidate hook will be called before flushing the fake front/back
buffer (that's typically once per frame -- not a lot worse than the
situation we were in before).
No effort has been made on preserving backwards compatibility with
version 2 of the flush extension, but I think it's acceptable because
AFAIK no released stack is making use of it.

Additions after 2.1 are implemented in a conditional way and will be
supported if available.

Remove const qualifier from _mesa_HashLookup() table parameter to
avoid LOCK/UNLOCK warnings in the function body.

My first reading of MS docs was wrong. It says:
All rendering contexts of a shared display list must use an identical
pixel format. Otherwise the results depend on the implementation of
OpenGL used.
That is, it is OK to share contexts with different pixel formats.
Adobe Premiere Pro tries to do that: share lists between a rgbx8 and a
rgba8 pixel format.

The problem with the old way is that passing 'progs/subdir' as argument
would fail.
|
|
Once if/elif evalutes to true, all subsequent conditions are always false.

This is a modification of commit 53d448657bd300ab68b2869b2fba76a627699baf.
The members cpts and spts are possibly used as arguments later in
the constructor.
