From f063712373e888addba235a58c5f907959218878 Mon Sep 17 00:00:00 2001 From: Jordan Justen Date: Fri, 19 Apr 2013 01:39:51 -0700 Subject: [PATCH] i965/gen6: Add support for layered renderbuffers Rather than pointing the surface_state directly at a single sub-image of the texture for rendering, we now point the surface_state at the top level of the texture, and configure the surface_state as needed based on this. v2: * Use SET_FIELD as suggested by Topi * Simplify min_array_element assignment as suggested by Topi v3: * Use irb->layer_count for depth instead of rb->Depth * Make gl_target const * depth - 1, not depth v4: * Merge in dd43900b & b875f39e fixes to prevent 3D texture piglit regressions Signed-off-by: Jordan Justen Reviewed-by: Topi Pohjolainen Reviewed-by: Kenneth Graunke --- src/mesa/drivers/dri/i965/brw_defines.h | 4 ++ src/mesa/drivers/dri/i965/gen6_surface_state.c | 79 +++++++++++++------------- 2 files changed, 43 insertions(+), 40 deletions(-) diff --git a/src/mesa/drivers/dri/i965/brw_defines.h b/src/mesa/drivers/dri/i965/brw_defines.h index 248a866377d..968aba1fb22 100644 --- a/src/mesa/drivers/dri/i965/brw_defines.h +++ b/src/mesa/drivers/dri/i965/brw_defines.h @@ -555,6 +555,10 @@ /* Surface state DW4 */ #define BRW_SURFACE_MIN_LOD_SHIFT 28 #define BRW_SURFACE_MIN_LOD_MASK INTEL_MASK(31, 28) +#define BRW_SURFACE_MIN_ARRAY_ELEMENT_SHIFT 17 +#define BRW_SURFACE_MIN_ARRAY_ELEMENT_MASK INTEL_MASK(27, 17) +#define BRW_SURFACE_RENDER_TARGET_VIEW_EXTENT_SHIFT 8 +#define BRW_SURFACE_RENDER_TARGET_VIEW_EXTENT_MASK INTEL_MASK(16, 8) #define BRW_SURFACE_MULTISAMPLECOUNT_1 (0 << 4) #define BRW_SURFACE_MULTISAMPLECOUNT_4 (2 << 4) #define GEN7_SURFACE_MULTISAMPLECOUNT_1 (0 << 3) diff --git a/src/mesa/drivers/dri/i965/gen6_surface_state.c b/src/mesa/drivers/dri/i965/gen6_surface_state.c index 0980fd1557b..65bcf7d0af2 100644 --- a/src/mesa/drivers/dri/i965/gen6_surface_state.c +++ b/src/mesa/drivers/dri/i965/gen6_surface_state.c @@ -26,6 +26,7 @@ #include "main/blend.h" #include "main/mtypes.h" #include "main/samplerobj.h" +#include "main/texformat.h" #include "program/prog_parameter.h" #include "intel_mipmap_tree.h" @@ -54,30 +55,17 @@ gen6_update_renderbuffer_surface(struct brw_context *brw, struct intel_renderbuffer *irb = intel_renderbuffer(rb); struct intel_mipmap_tree *mt = irb->mt; uint32_t *surf; - uint32_t tile_x, tile_y; uint32_t format = 0; /* _NEW_BUFFERS */ mesa_format rb_format = _mesa_get_render_format(ctx, intel_rb_format(irb)); + uint32_t surftype; + int depth = MAX2(irb->layer_count, 1); + const GLenum gl_target = + rb->TexImage ? rb->TexImage->TexObject->Target : GL_TEXTURE_2D; + uint32_t surf_index = brw->wm.prog_data->binding_table.render_target_start + unit; - assert(!layered); - - if (rb->TexImage && !brw->has_surface_tile_offset) { - intel_renderbuffer_get_tile_offsets(irb, &tile_x, &tile_y); - - if (tile_x != 0 || tile_y != 0) { - /* Original gen4 hardware couldn't draw to a non-tile-aligned - * destination in a miptree unless you actually setup your renderbuffer - * as a miptree and used the fragile lod/array_index/etc. controls to - * select the image.
