Subject: freedreno/ir3: add support for FS_COLOR0_WRITES_ALL_CBUFS property
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d13803c76fd7429df64c1aa3631dcc451e7f1a29;p=mesa.git

freedreno/ir3: add support for FS_COLOR0_WRITES_ALL_CBUFS property

This will enable the driver to tell which regids to link up to which
MRT outputs.
