Subject: st/dri: Add __DRI2rendererQueryExtension support
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5fe400d82a60eafefda4aedf36aaeac7975e3ae7;p=mesa.git

st/dri: Add __DRI2rendererQueryExtension support

The final step to get GLX_MESA_query_renderer working with gallium
drivers.

v2: Remove __DRI2_RENDERER_PREFERRED_PROFILE handling. It's already
handled in dri/common. Spotted by Marek.
