Subject: turnip: provide both emit_ib and emit_call
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5c63fc626f98def10d20971161e672f9e7cd341c;p=mesa.git

turnip: provide both emit_ib and emit_call

tu_cs_emit_ib emits a CP_INDIRECT_BUFFER for a BO.  tu_cs_emit_call
emits a CP_INDIRECT_BUFFER for each entry of a target cs.
