From: Marek Olšák Date: Sat, 7 Jul 2012 05:15:04 +0000 (+0200) Subject: r600g: move CB_TARGET_MASK setup into new cb_misc_state X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0ea76916e63f8fc556f5e8f5a46c196d317cd5ad;p=mesa.git r600g: move CB_TARGET_MASK setup into new cb_misc_state to remove some overhead from draw_vbo. This is a derived state. BTW, I've got no idea how compute interacts with 3D here, but it should use cb_misc_state, so that 3D and compute don't conflict.
