From 36c02ce4482c3efcd025e03d57dea720808d5b3d Mon Sep 17 00:00:00 2001 From: Rafael Antognolli Date: Wed, 15 Mar 2017 17:08:26 -0700 Subject: i965: Port Gen6+ 3DSTATE_CLIP state to genxml. Emit clip state on Gen6+ using brw_batch_emit helper, using pack structs from genxml. v3: - Lots style fixes (Ken) - Do not set CullTestEnableBitMask on Gen8+ (Ken) v4: - Do not include brw_defines_common.h. v5 (Ken): s/BRW_NEW_WM_PROG_DATA/BRW_NEW_FS_PROG_DATA/ Signed-off-by: Rafael Antognolli Reviewed-by: Kenneth Graunke --- src/mesa/drivers/dri/i965/brw_state.h | 1 - src/mesa/drivers/dri/i965/gen6_clip_state.c | 139 -------------------------- src/mesa/drivers/dri/i965/genX_state_upload.c | 138 ++++++++++++++++++++++++- 3 files changed, 135 insertions(+), 143 deletions(-) diff --git a/src/mesa/drivers/dri/i965/brw_state.h b/src/mesa/drivers/dri/i965/brw_state.h index 7b6d7184186..c26be41aa2e 100644 --- a/src/mesa/drivers/dri/i965/brw_state.h +++ b/src/mesa/drivers/dri/i965/brw_state.h @@ -109,7 +109,6 @@ extern const struct brw_tracked_state brw_cs_state;
