From 65c2362e88578575899bd208713d87b1206ad360 Mon Sep 17 00:00:00 2001 From: Sagar Ghuge Date: Tue, 4 Feb 2020 10:49:59 -0800 Subject: [PATCH] iris: Use modfiy disables for 3DSTATE_WM_DEPTH_STENCIL command Add new IRIS_DIRTY_STENCIL_REF dirty flag which would help us to trigger separate 3DSTATE_WM_DEPTH_STENCIL packet using modify disable fields. Instead of merging two packets into one in order to build 3DSTATE_WM_DEPTH_STENCIL state, set_stencil_ref can use IRIS_DIRTY_STENCIL_REF bit and bind_zsa_state can use IRIS_DIRTY_WN_DEPTH_STENCIL, both could cause packet to happen with available information using modify disable bits which allow us to construct packet by ignoring set of fields. v2: (Kenneth Graunke) - Fix condition ordering. - Club GEN cases.
