From a407636efb6c32cee81b9a1525dbc804aacd957b Mon Sep 17 00:00:00 2001 From: Roland Scheidegger Date: Tue, 12 Jan 2010 15:54:13 +0100 Subject: gallium: remove point_size_min and point_size_max from rasterizer state The state tracker is responsible for clamping to any graphics API enforced size min/max limits for both the static point_size setting as well as per vertex point size (in the vertex shader). Note that mesa state tracker didn't actually use these values. --- src/gallium/drivers/i965/brw_sf_state.c | 4 +--- src/gallium/drivers/r300/r300_state.c | 8 +++++--- src/gallium/drivers/svga/svga_context.h | 3 +-- src/gallium/drivers/svga/svga_pipe_rasterizer.c | 2 -- src/gallium/drivers/svga/svga_screen.c | 2 +- src/gallium/drivers/svga/svga_state_rss.c | 5 +++-- src/gallium/drivers/trace/tr_dump_state.c | 2 -- 7 files changed, 11 insertions(+), 15 deletions(-) (limited to 'src/gallium/drivers') diff --git a/src/gallium/drivers/i965/brw_sf_state.c b/src/gallium/drivers/i965/brw_sf_state.c index 25dc2b52e0..663a688772 100644 --- a/src/gallium/drivers/i965/brw_sf_state.c +++ b/src/gallium/drivers/i965/brw_sf_state.c @@ -126,9 +126,7 @@ sf_unit_populate_key(struct brw_context *brw, struct brw_sf_unit_key *key) key->point_sprite = rast->point_sprite; key->point_attenuated = rast->point_size_per_vertex; - key->point_size = CLAMP(rast->point_size, - rast->point_size_min, - rast->point_size_max); + key->point_size = rast->point_size; } static enum pipe_error diff --git a/src/gallium/drivers/r300/r300_state.c b/src/gallium/drivers/r300/r300_state.c index 78764ddc98..435e613ddf 100644 --- a/src/gallium/drivers/r300/r300_state.c +++ b/src/gallium/drivers/r300/r300_state.c @@ -618,10 +618,12 @@ static void* r300_create_rs_state(struct pipe_context* pipe, rs->point_size = pack_float_16_6x(state->point_size) | (pack_float_16_6x(state->point_size) << R300_POINTSIZE_X_SHIFT); - rs->point_minmax = - ((int)(state->point_size_min * 6.0) << + /* set hw limits - clamping done by state tracker in vs or point_size + XXX always need to emit this?
