The Gallium3D HUD has gain some new reporting capabilities for the Radeon Gallium3D R600 and RadeonSI drivers.

Marek Olšák has added a number of new optional queries for users to have shown on their display within the Gallium3D HUD when using the R600g/RadeonSI drivers. The new queries include the buffer wait time number of command stream flushes (num-cs-flushes), number of bytes moved (num-bytes-moved), VRAM usage (vram-usage), and GTT usage (GTT-usage). These additions are on top of the previous queries of number of draw calls, requested amount of video RAM, requested GTT, and buffer wait times.

These Radeon Gallium3D HUD additions landed with this Git commit. Enabling the Gallium3D HUD is via setting the query types within the GALLUUM_HUD environment variable.
