Using a temporary buffer for large discontiguous uploads into the common
buffer and a single buffered upload is faster than performing the
discontiguous copies through a mapping into the GTT.

Rather than performing lots of little writes to update the common bo
upon each update, write those into a static buffer and flush that when
full (or at the end of the batch). Doing so gives a dramatic performance
improvement over and above using mmaped access.

Reuse the new common upload buffer for uploading temporary indices and
rebuilt vertex arrays.

Dynamic arrays have the tendency to be small and so allocating a bo for
each one is overkill and we can exploit many efficiency gains by packing
them together.

The slightly less mechanical change of converting the emit_reloc calls
will follow.

This should help for the usage by the VBO module, where we would upload
the whole remaining chunk of the buffer for a series of range maps that should
cover just a segment of it.
|
|
Passes glean's bufferObject test, and should provide good performance in the
cases applications are expected to use.
|
|
Initialize all driver function hooks before calling _mesa_initialize_context(),
and handle all buffer objects in intel_buffer_object().
Fixes assertion failure when running glxinfo.

This saves doing swtnl from uncached memory, which is painful. Improves
clutter test-text performance by 10% since it started using VBOs.

|
This looks to be a win of a few percent in cairogears with new vbo code,
thanks to not polluting caches.

To do so, merge the remainnig necessary code from the buffers, blit, span, and
screen code to shared, and replace it with those.
