Subject: freedreno: Add INDIRECT_COUNT CP_DRAW_INDIRECT_MULTI variants
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=cd78a7a5ff5590bdc3c118e553affd11d9438cf7;p=mesa.git

freedreno: Add INDIRECT_COUNT CP_DRAW_INDIRECT_MULTI variants

These have an indirect count which is loaded from an iova, and the
minimum is taken between the indirect and direct counts. Note, I also
had to fix gen_header.py to deal with the extra-long names we get.
