Author: Lionel Landwerlin <[email protected]> Date: Tue Sep 15 21:40:51 2020 +0300 blorp: allow blits with floating point source layers The current blorp API only allows source layers for 3D images to be integers. That is causing problems with the Vulkan API where we need to be able to use a 3D layer that could be in between 2 layers. This change allows a floating point value to be passed for blits and internally sets up the input parameters to pass floating point values to kernels. v2: Use tex op to determinate what types are the coordinates (Jason) Drop setting params->z (Lionel) v3: Fix nir_texop_txf_ms_mcs op not considered as having integer coords (Lionel) v4: Fix incorrect test on nir_texop_txf_ms_mcs (Ivan) Signed-off-by: Lionel Landwerlin <[email protected]> Closes: https://gitlab.freedesktop.org/mesa/mesa/-/issues/3458 Cc: <[email protected]> Reviewed-by: Jason Ekstrand <[email protected]> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/6909> (cherry picked from commit 87934f02f9da94f1a493096049c229b973e4785c) --- src/intel/blorp/blorp.c | 2 +- src/intel/blorp/blorp.h | 2 +- src/intel/blorp/blorp_blit.c | 13 +++++++++---- src/intel/blorp/blorp_priv.h | 6 +++--- 4 files changed, 14 insertions(+), 9 deletions(-) diff --git a/src/intel/blorp/blorp.c b/src/intel/blorp/blorp.c index 681c8f1cc0c..58c43cb5f2b 100644 --- a/src/intel/blorp/blorp.c +++ b/src/intel/blorp/blorp.c @@ -63,7 +63,7 @@ void brw_blorp_surface_info_init(struct blorp_context *blorp, struct brw_blorp_surface_info *info, const struct blorp_surf *surf, - unsigned int level, unsigned int layer, + unsigned int level, float layer, enum isl_format format, bool is_render_target) { memset(info, 0, sizeof(*info)); diff --git a/src/intel/blorp/blorp.h b/src/intel/blorp/blorp.h index b88178266c3..f8d8b0b8420 100644 --- a/src/intel/blorp/blorp.h +++ b/src/intel/blorp/blorp.h @@ -133,7 +133,7 @@ enum blorp_filter { void blorp_blit(struct blorp_batch *batch, const struct blorp_surf *src_surf, - unsigned src_level, unsigned src_layer, + unsigned src_level, float src_layer, enum isl_format src_format, struct isl_swizzle src_swizzle, const struct blorp_surf *dst_surf, unsigned dst_level, unsigned dst_layer, diff --git a/src/intel/blorp/blorp_blit.c b/src/intel/blorp/blorp_blit.c index 3aac0abf274..d413e169ac4 100644 --- a/src/intel/blorp/blorp_blit.c +++ b/src/intel/blorp/blorp_blit.c @@ -56,7 +56,7 @@ brw_blorp_blit_vars_init(nir_builder *b, struct brw_blorp_blit_vars *v, LOAD_INPUT(discard_rect, glsl_vec4_type()) LOAD_INPUT(rect_grid, glsl_vec4_type()) LOAD_INPUT(coord_transform, glsl_vec4_type()) - LOAD_INPUT(src_z, glsl_uint_type()) + LOAD_INPUT(src_z, glsl_float_type()) LOAD_INPUT(src_offset, glsl_vector_type(GLSL_TYPE_UINT, 2)) LOAD_INPUT(dst_offset, glsl_vector_type(GLSL_TYPE_UINT, 2)) LOAD_INPUT(src_inv_size, glsl_vector_type(GLSL_TYPE_FLOAT, 2)) @@ -154,8 +154,13 @@ blorp_create_nir_tex_instr(nir_builder *b, struct brw_blorp_blit_vars *v, * more explicit in the future. */ assert(pos->num_components >= 2); - pos = nir_vec3(b, nir_channel(b, pos, 0), nir_channel(b, pos, 1), - nir_load_var(b, v->v_src_z)); + if (op == nir_texop_txf || op == nir_texop_txf_ms || op == nir_texop_txf_ms_mcs) { + pos = nir_vec3(b, nir_channel(b, pos, 0), nir_channel(b, pos, 1), + nir_f2i32(b, nir_load_var(b, v->v_src_z))); + } else { + pos = nir_vec3(b, nir_channel(b, pos, 0), nir_channel(b, pos, 1), + nir_load_var(b, v->v_src_z)); + } tex->src[0].src_type = nir_tex_src_coord; tex->src[0].src = nir_src_for_ssa(pos); @@ -2319,7 +2324,7 @@ do_blorp_blit(struct blorp_batch *batch, void blorp_blit(struct blorp_batch *batch, const struct blorp_surf *src_surf, - unsigned src_level, unsigned src_layer, + unsigned src_level, float src_layer, enum isl_format src_format, struct isl_swizzle src_swizzle, const struct blorp_surf *dst_surf, unsigned dst_level, unsigned dst_layer, diff --git a/src/intel/blorp/blorp_priv.h b/src/intel/blorp/blorp_priv.h index 63b0ce9a88d..f34168681c0 100644 --- a/src/intel/blorp/blorp_priv.h +++ b/src/intel/blorp/blorp_priv.h @@ -61,7 +61,7 @@ struct brw_blorp_surface_info struct isl_view view; /* Z offset into a 3-D texture or slice of a 2-D array texture. */ - uint32_t z_offset; + float z_offset; uint32_t tile_x_sa, tile_y_sa; }; @@ -70,7 +70,7 @@ void brw_blorp_surface_info_init(struct blorp_context *blorp, struct brw_blorp_surface_info *info, const struct blorp_surf *surf, - unsigned int level, unsigned int layer, + unsigned int level, float layer, enum isl_format format, bool is_render_target); void blorp_surf_convert_to_single_slice(const struct isl_device *isl_dev, @@ -148,7 +148,7 @@ struct brw_blorp_wm_inputs /* Minimum layer setting works for all the textures types but texture_3d * for which the setting has no effect.
