Subject: st/nine: Decompose nine_context_set_stream_source
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=08b717dfd33cb733ef3558ef3edf2e051396c462;p=mesa.git

st/nine: Decompose nine_context_set_stream_source

Part of the refactor to move all gallium calls to
nine_state.c, and have all internal states required
for those calls in nine_context.
