From cfcc2ef587fad91ad1dff1abbd42886dbe9cc095 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Thu, 9 Dec 2010 10:03:49 -0800 Subject: i965: Set render_cache_read_write surface state bit on gen6 constant surfs. This is said to be required in the spec, even when you aren't doing writes. --- src/mesa/drivers/dri/i965/brw_structs.h | 5 +++++ src/mesa/drivers/dri/i965/brw_wm_surface_state.c | 4 ++++ 2 files changed, 9 insertions(+) (limited to 'src/mesa/drivers/dri/i965') diff --git a/src/mesa/drivers/dri/i965/brw_structs.h b/src/mesa/drivers/dri/i965/brw_structs.h index 0e1f3c9bb8..d341187c1b 100644 --- a/src/mesa/drivers/dri/i965/brw_structs.h +++ b/src/mesa/drivers/dri/i965/brw_structs.h @@ -1179,6 +1179,11 @@ struct brw_surface_state GLuint cube_pos_x:1; GLuint cube_neg_x:1; GLuint pad:4; + /* Required on gen6 for surfaces accessed through render cache messages. + */ + GLuint render_cache_read_write:1; + /* Ironlake and newer: instead of replicating one of the texels */ + GLuint cube_corner_average:1; GLuint mipmap_layout_mode:1; GLuint vert_line_stride_ofs:1; GLuint vert_line_stride:1; diff --git a/src/mesa/drivers/dri/i965/brw_wm_surface_state.c b/src/mesa/drivers/dri/i965/brw_wm_surface_state.c index 76fc94df1f..fb0e34e94f 100644 --- a/src/mesa/drivers/dri/i965/brw_wm_surface_state.c +++ b/src/mesa/drivers/dri/i965/brw_wm_surface_state.c @@ -274,6 +274,7 @@ brw_create_constant_surface(struct brw_context *brw, drm_intel_bo **out_bo, uint32_t *out_offset) { + struct intel_context *intel = &brw->intel; const GLint w = width - 1; struct brw_surface_state surf; void *map; @@ -284,6 +285,9 @@ brw_create_constant_surface(struct brw_context *brw, surf.ss0.surface_type = BRW_SURFACE_BUFFER; surf.ss0.surface_format = BRW_SURFACEFORMAT_R32G32B32A32_FLOAT; + if (intel->gen >= 6) + surf.ss0.render_cache_read_write = 1; + assert(bo); surf.ss1.base_addr = bo->offset; /* reloc */ -- cgit v1.2.3
