From: Samuel Pitoiset Date: Tue, 5 Jan 2016 20:20:06 +0000 (+0100) Subject: st/mesa: add a second pipeline for compute X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=08c46025c87654fbc885136a2c8cc4cce902dd37;p=mesa.git st/mesa: add a second pipeline for compute Compute needs a new and different validation path. Changes from v2: - make use of unreachable() instead of assert() when the pipeline is invalid - move the st_pipeline enumeration to st_context.h instead of st_api.h Signed-off-by: Samuel Pitoiset Reviewed-by: Ilia Mirkin Reviewed-by: Marek Olšák --- diff --git a/src/mesa/state_tracker/st_atom.c b/src/mesa/state_tracker/st_atom.c index 4b89ade1b15..2d89512e854 100644 --- a/src/mesa/state_tracker/st_atom.c +++ b/src/mesa/state_tracker/st_atom.c @@ -38,9 +38,9 @@ /** - * This is used to initialize st->atoms[]. + * This is used to initialize st->render_atoms[]. */ -static const struct st_tracked_state *atoms[] = +static const struct st_tracked_state *render_atoms[] = { &st_update_depth_stencil_alpha, &st_update_clip, @@ -93,6 +93,15 @@ static const struct st_tracked_state *atoms[] = };
