From dfc02e3784e521c07a22ff2ffc4bf02f022e9898 Mon Sep 17 00:00:00 2001 From: Roland Scheidegger Date: Wed, 10 Feb 2010 21:14:18 +0100 Subject: [PATCH] st/mesa: more fixes for stencil ref change. compiles. Might need to do something to make it possible to save/restore stencil ref. --- src/mesa/state_tracker/st_atom_depth.c | 1 - src/mesa/state_tracker/st_cb_clear.c | 21 ++++++++++++++++++++- 2 files changed, 20 insertions(+), 2 deletions(-) diff --git a/src/mesa/state_tracker/st_atom_depth.c b/src/mesa/state_tracker/st_atom_depth.c index 4395c682093..3c07afba9aa 100644 --- a/src/mesa/state_tracker/st_atom_depth.c +++ b/src/mesa/state_tracker/st_atom_depth.c @@ -123,7 +123,6 @@ update_depth_stencil_alpha(struct st_context *st) dsa->stencil[1].fail_op = gl_stencil_op_to_pipe(ctx->Stencil.FailFunc[back]); dsa->stencil[1].zfail_op = gl_stencil_op_to_pipe(ctx->Stencil.ZFailFunc[back]); dsa->stencil[1].zpass_op = gl_stencil_op_to_pipe(ctx->Stencil.ZPassFunc[back]); - dsa->stencil[1].ref_value = ctx->Stencil.Ref[back] & 0xff; dsa->stencil[1].valuemask = ctx->Stencil.ValueMask[back] & 0xff; dsa->stencil[1].writemask = ctx->Stencil.WriteMask[back] & 0xff; sr.ref_value[1] = ctx->Stencil.Ref[back] & 0xff; diff --git a/src/mesa/state_tracker/st_cb_clear.c b/src/mesa/state_tracker/st_cb_clear.c index 0c7bcb85973..ed92e3928e3 100644 --- a/src/mesa/state_tracker/st_cb_clear.c +++ b/src/mesa/state_tracker/st_cb_clear.c @@ -192,6 +192,7 @@ clear_with_quad(GLcontext *ctx, GLboolean color, GLboolean depth, GLboolean stencil) { struct st_context *st = ctx->st; + struct pipe_stencil_ref stencil_ref; const GLfloat x0 = (GLfloat) ctx->DrawBuffer->_Xmin; const GLfloat x1 = (GLfloat) ctx->DrawBuffer->_Xmax; GLfloat y0, y1; @@ -247,6 +248,7 @@ clear_with_quad(GLcontext *ctx, { struct pipe_depth_stencil_alpha_state depth_stencil; memset(&depth_stencil, 0, sizeof(depth_stencil)); + memset(&stencil_ref, 0, sizeof(stencil_ref)); if (depth) { depth_stencil.depth.enabled = 1; depth_stencil.depth.writemask = 1; @@ -259,9 +261,10 @@ clear_with_quad(GLcontext *ctx, depth_stencil.stencil[0].fail_op = PIPE_STENCIL_OP_REPLACE; depth_stencil.stencil[0].zpass_op = PIPE_STENCIL_OP_REPLACE; depth_stencil.stencil[0].zfail_op = PIPE_STENCIL_OP_REPLACE; - depth_stencil.stencil[0].ref_value = ctx->Stencil.Clear; depth_stencil.stencil[0].valuemask = 0xff; depth_stencil.stencil[0].writemask = ctx->Stencil.WriteMask[0] & 0xff; + stencil_ref.ref_value[0] = ctx->Stencil.Clear; + cso_set_stencil_ref(st->cso_context, &stencil_ref); } cso_set_depth_stencil_alpha(st->cso_context, &depth_stencil); @@ -281,6 +284,22 @@ clear_with_quad(GLcontext *ctx, cso_restore_rasterizer(st->cso_context); cso_restore_fragment_shader(st->cso_context); cso_restore_vertex_shader(st->cso_context); + + /* cannot restore stencil ref.
