Hi,
This patch restores the previous memory characteristic of the recently removed
r600g winsys. Static and immutable buffers were placed in any case in vram.
This really improoves rendering performance for some OpenSceneGraph based
applications I often use for testing here.
Please review and apply if it's ok.
Thanks
Mathias

Subject: [PATCH 2/2] r600g: restore the old r600g winsys memory
characteristics.
Use VRAM for static and immutable buffers. This restores the
recently removed r600g winsys behaviour for memory locations.
This also improoves rendering times on the gpu for some
OpenSceneGraph based test cases by about 15%.
