Subject: targets/dri: Add __driDriverGetExtensions_nouveau symbol
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5b7e43aea89847100b929989c21d23da124d4936;p=mesa.git

targets/dri: Add __driDriverGetExtensions_nouveau symbol

The symbol is introduced by the mesa megadrivers, and adding
gallium support for it will allow us to merge st/dri/drm and
st/dri/sw. Resulting in a single dri library across gallium.

v2: Rebase on top of gallium dri3.
