From c93b17be19fe2a40eb30f53e738e91f51a16ea72 Mon Sep 17 00:00:00 2001 From: Rafael Antognolli Date: Tue, 9 May 2017 17:12:08 -0700 Subject: [PATCH] i965/genxml: Mostly style fixes for emit_vertices code. Several issues were caught on review after the original patch landed. This commit fixes them. v2: - Fix padding (Topi) - Remove .DestinationElementOffset change from this patch (Topi) Signed-off-by: Rafael Antognolli Reviewed-by: Topi Pohjolainen Reviewed-by: Lionel Landwerlin Reviewed-by: Kenneth Graunke --- src/mesa/drivers/dri/i965/genX_state_upload.c | 42 ++++++++----------- 1 file changed, 17 insertions(+), 25 deletions(-) diff --git a/src/mesa/drivers/dri/i965/genX_state_upload.c b/src/mesa/drivers/dri/i965/genX_state_upload.c index bc7f068d5bb..6d4d0d3e2c0 100644 --- a/src/mesa/drivers/dri/i965/genX_state_upload.c +++ b/src/mesa/drivers/dri/i965/genX_state_upload.c @@ -372,7 +372,7 @@ is_passthru_format(uint32_t format) } UNUSED static int -genX(uploads_needed)(uint32_t format) +uploads_needed(uint32_t format) { if (!is_passthru_format(format)) return 1; @@ -454,8 +454,8 @@ genX(emit_vertices)(struct brw_context *brw) #if GEN_GEN >= 8 struct gl_context *ctx = &brw->ctx; - bool uses_edge_flag = (ctx->Polygon.FrontMode != GL_FILL || - ctx->Polygon.BackMode != GL_FILL); + const bool uses_edge_flag = (ctx->Polygon.FrontMode != GL_FILL || + ctx->Polygon.BackMode != GL_FILL); if (vs_prog_data->uses_vertexid || vs_prog_data->uses_instanceid) { unsigned vue = brw->vb.nr_enabled; @@ -524,7 +524,7 @@ genX(emit_vertices)(struct brw_context *brw) struct brw_vertex_element *input = brw->vb.enabled[i]; uint32_t format = brw_get_vertex_surface_type(brw, input->glarray); - if (genX(uploads_needed(format)) > 1) + if (uploads_needed(format) > 1) nr_elements++; } #endif @@ -537,7 +537,8 @@ genX(emit_vertices)(struct brw_context *brw) * a VE loads from them. */ if (nr_elements == 0) { - dw = brw_batch_emitn(brw, GENX(3DSTATE_VERTEX_ELEMENTS), 1 + GENX(VERTEX_ELEMENT_STATE_length)); + dw = brw_batch_emitn(brw, GENX(3DSTATE_VERTEX_ELEMENTS), + 1 + GENX(VERTEX_ELEMENT_STATE_length)); struct GENX(VERTEX_ELEMENT_STATE) elem = { .Valid = true, .SourceElementFormat = ISL_FORMAT_R32G32B32A32_FLOAT, @@ -558,11 +559,6 @@ genX(emit_vertices)(struct brw_context *brw) uses_draw_params + vs_prog_data->uses_drawid; if (nr_buffers) { -#if GEN_GEN >= 6 - assert(nr_buffers <= 33); -#else - assert(nr_buffers <= 17); -#endif assert(nr_buffers <= (GEN_GEN >= 6 ? 33 : 17)); dw = brw_batch_emitn(brw, GENX(3DSTATE_VERTEX_BUFFERS), @@ -575,11 +571,12 @@ genX(emit_vertices)(struct brw_context *brw) * half-float and 8 and 16-bit integer formats.
