From 1877e6cd2d76143ef8a9c516122afe614ae3b4a4 Mon Sep 17 00:00:00 2001 From: Keith Whitwell Date: Tue, 17 Nov 2009 14:46:23 -0800 Subject: i965g: handle special vs outputs specially Where vs output semantic tags indicate an output is signficant for fixed function processing (such as clipping, unfilled modes, etc), retain information about that output so that we can get to it easily later on. Fix up the unfilled processing, but hard-wire edgeflag to one for now. With this change, trivial/tri-unfilled works. --- src/gallium/drivers/i965/brw_clip.c | 45 +++++++++++++++++++++++++++---------- 1 file changed, 33 insertions(+), 12 deletions(-) (limited to 'src/gallium/drivers/i965/brw_clip.c') diff --git a/src/gallium/drivers/i965/brw_clip.c b/src/gallium/drivers/i965/brw_clip.c index 35e1d2fdbd0..4ec7b823e83 100644 --- a/src/gallium/drivers/i965/brw_clip.c +++ b/src/gallium/drivers/i965/brw_clip.c @@ -58,7 +58,6 @@ compile_clip_prog( struct brw_context *brw, const GLuint *program; GLuint program_size; GLuint delta; - GLuint i; memset(&c, 0, sizeof(c)); @@ -82,16 +81,26 @@ compile_clip_prog( struct brw_context *brw, else delta = REG_SIZE; - /* XXX: c.offset is now pretty redundant: - */ - for (i = 0; i < c.key.nr_attrs; i++) { - c.offset[i] = delta; - delta += ATTR_SIZE; - } - /* XXX: c.nr_attrs is very redundant: */ c.nr_attrs = c.key.nr_attrs; + + c.offset_hpos = delta + c.key.output_hpos * ATTR_SIZE; + + if (c.key.output_color0) + c.offset_color0 = delta + c.key.output_color0 * ATTR_SIZE; + + if (c.key.output_color1) + c.offset_color1 = delta + c.key.output_color1 * ATTR_SIZE; + + if (c.key.output_bfc0) + c.offset_bfc0 = delta + c.key.output_bfc0 * ATTR_SIZE; + + if (c.key.output_bfc1) + c.offset_bfc1 = delta + c.key.output_bfc1 * ATTR_SIZE; + + if (c.key.output_edgeflag) + c.offset_edgeflag = delta + c.key.output_edgeflag * ATTR_SIZE; if (BRW_IS_IGDNG(brw)) c.nr_regs = (c.nr_attrs + 1) / 2 + 3; /* are vertices packed, or reg-aligned? */ @@ -158,21 +167,33 @@ compile_clip_prog( struct brw_context *brw, static enum pipe_error upload_clip_prog(struct brw_context *brw) { - enum pipe_error ret; + const struct brw_vertex_shader *vs = brw->curr.vertex_shader; struct brw_clip_prog_key key; + enum pipe_error ret; /* Populate the key, starting from the almost-complete version from * the rast state. */ /* PIPE_NEW_RAST */ - memcpy(&key, &brw->curr.rast->clip_key, sizeof key); - + key = brw->curr.rast->clip_key; + /* BRW_NEW_REDUCED_PRIMITIVE */ key.primitive = brw->reduced_primitive; + /* XXX: if edgeflag is moved to a proper TGSI vs output, can remove + * dependency on CACHE_NEW_VS_PROG + */ + /* CACHE_NEW_VS_PROG */ + key.nr_attrs = brw->vs.prog_data->nr_outputs; + key.output_edgeflag = brw->vs.prog_data->output_edgeflag; + /* PIPE_NEW_VS */ - key.nr_attrs = brw->curr.vertex_shader->info.file_max[TGSI_FILE_OUTPUT] + 1; + key.output_hpos = vs->output_hpos; + key.output_color0 = vs->output_color0; + key.output_color1 = vs->output_color1; + key.output_bfc0 = vs->output_bfc0; + key.output_bfc1 = vs->output_bfc1; /* PIPE_NEW_CLIP */ key.nr_userclip = brw->curr.ucp.nr; -- cgit v1.2.3
