In OpenGL ES (all versions!) and OpenGL compatibility profile,
applications don't have to call Gen functions.  The GL spec is very

Here's the problem scenario:

 - Application decides to use the same name for an object of the same

Some meta operations can be called recursively.  Future changes (the

This also fixes another latent bug in meta.  In a multithreaded,
multicontext application, one thread can delete an object that is bound
in another thread.  That object continues to exist until it is unbound
(i.e., its refcount drops to zero).  Meta unbinds objects all over the
place.  As a result, the rebind in _mesa_meta_end could fail because the

See https://bugs.freedesktop.org/show_bug.cgi?id=92363#c8.

i965: Push most TES inputs in vec4 mode.

(This is commit 4a1c8a3037cd29938b2a6e2c680c341e9903cfbe for vec4 mode.)

Using the push model for inputs is much more efficient than pulling
inputs - the hardware can simply copy a large chunk into URB registers
at thread creation time, rather than having the thread send messages to
request data from the L3 cache.  Unfortunately, it's possible to have
more TES inputs than fit in registers, so we have to fall back to the
pull model in some cases.

However, it turns out that most tessellation evaluation shaders are
fairly simple, and don't use many inputs.  An arbitrary cut-off of
24 vec4 slots (12 registers) should suffice.  (I chose this instead of
the 32 vec4 slots used in the scalar backend to avoid regressing a few
Piglit tests due to the vec4 register allocator being too stupid to
figure out what to do.  We probably ought to fix that, but it's a
separate issue.)

st/nine: Fix second Multithreading issue with MANAGED buffers

Here is another threading issue with MANAGED buffers:

Thread 1: buffer creation
Thread 1: buffer lock
Thread 2: Draw call
Thread 1: writes data
Thread 1: Unlock

Without this patch, the buffer is initially dirty
and in the list of things to upload after its creation.
The draw call will then upload the data and unset the dirty flag,
and the Unlock won't trigger a second upload.

st/nine: Fix Multithreading issue with MANAGED buffers

d3d calls are protected by mutexes, however if app is doing in
two threads:

Thread 1: buffer Lock
Thread 2: Draw call
Thread 1: writes data
Thread 1: Unlock

Then before this patch, the Draw call would begin to upload
the buffer.

Solves this by moving the moment we add the buffer to the queue
of things to upload (We move it from Lock time to Unlock time).
