Subject: i965: Delete update_renderbuffer_surface flags.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=081c54099c28fb480480bac2c9983df4c3ee4382;p=mesa.git

i965: Delete update_renderbuffer_surface flags.

We don't need yet another set of flags.  The function already has access
to both brw and the unit, so it can check brw->draw_aux_buffer_disabled
itself in one line of code.  The layered flag was only used to assert
that Gen4-5 doesn't do layered rendering, which isn't that useful.
