From ab12e764ba3f57ad9f0d7252262cfc6e07839928 Mon Sep 17 00:00:00 2001 From: Roland Scheidegger Date: Wed, 11 Nov 2009 17:57:56 -0800 Subject: i965: fix EXT_provoking_vertex support This didn't work for quad/quadstrips at all, and for all other primitive types it only worked when they were unclipped. Fix up the former in gs stage (could probably do without these changes and instead set QuadsFollowProvokingVertexConvention to false), and the rest in clip stage. --- src/mesa/drivers/dri/i965/brw_clip.c | 1 + src/mesa/drivers/dri/i965/brw_clip.h | 7 +++--- src/mesa/drivers/dri/i965/brw_clip_line.c | 8 +++++-- src/mesa/drivers/dri/i965/brw_clip_tri.c | 12 +++++++--- src/mesa/drivers/dri/i965/brw_gs.c | 10 +++++--- src/mesa/drivers/dri/i965/brw_gs.h | 7 +++--- src/mesa/drivers/dri/i965/brw_gs_emit.c | 38 ++++++++++++++++++++++--------- src/mesa/drivers/dri/i965/brw_sf_state.c | 7 +++--- 8 files changed, 61 insertions(+), 29 deletions(-) (limited to 'src/mesa') diff --git a/src/mesa/drivers/dri/i965/brw_clip.c b/src/mesa/drivers/dri/i965/brw_clip.c index 20a927cf38..f45dcf8282 100644 --- a/src/mesa/drivers/dri/i965/brw_clip.c +++ b/src/mesa/drivers/dri/i965/brw_clip.c @@ -156,6 +156,7 @@ static void upload_clip_prog(struct brw_context *brw) key.attrs = brw->vs.prog_data->outputs_written;
