Subject: st/nine: Add CSMT_NO_WAIT_WITH_COUNTER
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8a69343f1e8c59137d7b746e5ca8ef1e7944c7d6;p=mesa.git

st/nine: Add CSMT_NO_WAIT_WITH_COUNTER

Similar to the other macros, but introduces a counter,
which enables to know when the instructions has been
executed.
