Subject: ilo: simplify ilo_render_get_query_len()
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7fc74153166ea59d72083f9a09e9ddb966a23985;p=mesa.git

ilo: simplify ilo_render_get_query_len()

For all supported query types, we always emit a PIPE_CONTROL.  Call
ilo_render_get_flush_len() for simplicity and clarity.
