Subject: radv: add the trace BO to the list when starting a new cmdbuf
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e8f82b33fbb572dea1c5b645ea3520915061cddc;p=mesa.git

radv: add the trace BO to the list when starting a new cmdbuf

That might reduce CPU overhead a little bit when using
RADV_TRACE_FILE.
