Subject: broadcom/vc5: Disable TF on V3D 4.x when drawing with queries disabled.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=262208eb3c2c53a1fd807bc76b12088f6ce2c56d;p=mesa.git

broadcom/vc5: Disable TF on V3D 4.x when drawing with queries disabled.

On 3.x, we just don't flag the primitive as needing TF, but those
primitive bits are now allocated to the new primitive types.  Now we need
to actually update the enable flag at draw time.
