From 677a4406d20e0a2b6d92c34e9ff6716f31ba1382 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Marek=20Ol=C5=A1=C3=A1k?= Date: Wed, 15 Jun 2011 02:24:03 +0200 Subject: [PATCH] r600g: force OpenGL's BASE_LEVEL behavior on r600-r700 This sets the base level as the zero level, which fixes piglit/texturing/tex-miplevel-selection*. The r600 hardware ignores the BASE_LEVEL field in some cases, so we can't use it. Evergreen might need this too. --- src/gallium/drivers/r600/r600_state.c | 26 ++++++++++++++++---------- 1 file changed, 16 insertions(+), 10 deletions(-) diff --git a/src/gallium/drivers/r600/r600_state.c b/src/gallium/drivers/r600/r600_state.c index 3b6e2dc99a5..197279920a2 100644 --- a/src/gallium/drivers/r600/r600_state.c +++ b/src/gallium/drivers/r600/r600_state.c @@ -416,7 +416,7 @@ static struct pipe_sampler_view *r600_create_sampler_view(struct pipe_context *c uint32_t word4 = 0, yuv_format = 0, pitch = 0; unsigned char swizzle[4], array_mode = 0, tile_type = 0; struct r600_bo *bo[2]; - unsigned height, depth; + unsigned width, height, depth, offset_level, last_level; if (resource == NULL) return NULL; @@ -442,7 +442,7 @@ static struct pipe_sampler_view *r600_create_sampler_view(struct pipe_context *c } desc = util_format_description(state->format); if (desc == NULL) { - R600_ERR("unknow format %d\n", state->format); + R600_ERR("unknown format %d\n", state->format); } tmp = (struct r600_resource_texture *)texture; if (tmp->depth && !tmp->is_flushing_texture) { @@ -458,12 +458,18 @@ static struct pipe_sampler_view *r600_create_sampler_view(struct pipe_context *c rbuffer = &tmp->resource; bo[0] = rbuffer->bo; bo[1] = rbuffer->bo; - pitch = align(tmp->pitch_in_blocks[0] * util_format_get_blockwidth(state->format), 8); + + offset_level = state->u.tex.first_level; + last_level = state->u.tex.last_level - offset_level; + width = u_minify(texture->width0, offset_level); + height = u_minify(texture->height0, offset_level); + depth = u_minify(texture->depth0, offset_level); + + pitch = align(tmp->pitch_in_blocks[offset_level] * + util_format_get_blockwidth(state->format), 8); array_mode = tmp->array_mode[0]; tile_type = tmp->tile_type; - height = texture->height0; - depth = texture->depth0; if (texture->target == PIPE_TEXTURE_1D_ARRAY) { height = 1; depth = texture->array_size; @@ -478,18 +484,18 @@ static struct pipe_sampler_view *r600_create_sampler_view(struct pipe_context *c S_038000_TILE_MODE(array_mode) | S_038000_TILE_TYPE(tile_type) | S_038000_PITCH((pitch / 8) - 1) | - S_038000_TEX_WIDTH(texture->width0 - 1)); + S_038000_TEX_WIDTH(width - 1)); rstate->val[1] = (S_038004_TEX_HEIGHT(height - 1) | S_038004_TEX_DEPTH(depth - 1) | S_038004_DATA_FORMAT(format)); - rstate->val[2] = (tmp->offset[0] + r600_bo_offset(bo[0])) >> 8; - rstate->val[3] = (tmp->offset[1] + r600_bo_offset(bo[1])) >> 8; + rstate->val[2] = (tmp->offset[offset_level] + r600_bo_offset(bo[0])) >> 8; + rstate->val[3] = (tmp->offset[offset_level+1] + r600_bo_offset(bo[1])) >> 8; rstate->val[4] = (word4 | S_038010_SRF_MODE_ALL(V_038010_SRF_MODE_ZERO_CLAMP_MINUS_ONE) | S_038010_REQUEST_SIZE(1) | S_038010_ENDIAN_SWAP(endian) | - S_038010_BASE_LEVEL(state->u.tex.first_level)); - rstate->val[5] = (S_038014_LAST_LEVEL(state->u.tex.last_level) | + S_038010_BASE_LEVEL(0)); + rstate->val[5] = (S_038014_LAST_LEVEL(last_level) | S_038014_BASE_ARRAY(state->u.tex.first_layer) | S_038014_LAST_ARRAY(state->u.tex.last_layer)); rstate->val[6] = (S_038018_TYPE(V_038010_SQ_TEX_VTX_VALID_TEXTURE) | -- 2.30.2
