From b6ad7075b93bcea157eb74fc3129d61b1fb2a5ca Mon Sep 17 00:00:00 2001 From: =?utf8?q?Marek=20Ol=C5=A1=C3=A1k?= Date: Wed, 4 Apr 2018 18:20:53 -0400 Subject: [PATCH] gallium/hud: add a simple HUD view that only draws text Add this prefix to the env var: "simple," For example: GALLIUM_HUD=simple,fps The X coordinates are the same, but the Y coordinates are different, because there is only text. '+' happens to behave the same as "\n". ',' happens to behave the same as "\n\n". --- src/gallium/auxiliary/hud/hud_context.c | 72 ++++++++++++++++++++----- src/gallium/auxiliary/hud/hud_private.h | 3 +- 2 files changed, 60 insertions(+), 15 deletions(-) diff --git a/src/gallium/auxiliary/hud/hud_context.c b/src/gallium/auxiliary/hud/hud_context.c index 4d2458eb2e4..1baaabbb38e 100644 --- a/src/gallium/auxiliary/hud/hud_context.c +++ b/src/gallium/auxiliary/hud/hud_context.c @@ -398,6 +398,26 @@ hud_pane_accumulate_vertices(struct hud_context *hud, hud->whitelines.num_vertices += num/2; } +static void +hud_pane_accumulate_vertices_simple(struct hud_context *hud, + const struct hud_pane *pane) +{ + struct hud_graph *gr; + unsigned i; + char str[32]; + + /* draw info below the pane */ + i = 0; + LIST_FOR_EACH_ENTRY(gr, &pane->graph_list, head) { + unsigned x = pane->x1; + unsigned y = pane->y_simple + i*hud->font.glyph_height; + + number_to_human_readable(gr->current_value, pane->type, str); + hud_draw_string(hud, x, y, "%s: %s", gr->name, str); + i++; + } +} + static void hud_pane_draw_colored_objects(struct hud_context *hud, const struct hud_pane *pane) @@ -547,6 +567,23 @@ hud_draw_results(struct hud_context *hud, struct pipe_resource *tex) } pipe_resource_reference(&hud->bg.vbuf.buffer.resource, NULL); + /* draw accumulated vertices for text */ + if (hud->text.num_vertices) { + cso_set_vertex_buffers(cso, cso_get_aux_vertex_buffer_slot(cso), 1, + &hud->text.vbuf); + cso_set_fragment_shader_handle(hud->cso, hud->fs_text); + cso_draw_arrays(cso, PIPE_PRIM_QUADS, 0, hud->text.num_vertices); + } + pipe_resource_reference(&hud->text.vbuf.buffer.resource, NULL); + + if (hud->simple) { + cso_restore_state(cso); + cso_restore_constant_buffer_slot0(cso, PIPE_SHADER_VERTEX); + + pipe_surface_reference(&surf, NULL); + return; + } + /* draw accumulated vertices for white lines */ cso_set_blend(cso, &hud->no_blend); @@ -568,17 +605,8 @@ hud_draw_results(struct hud_context *hud, struct pipe_resource *tex) } pipe_resource_reference(&hud->whitelines.vbuf.buffer.resource, NULL); - /* draw accumulated vertices for text */ - cso_set_blend(cso, &hud->alpha_blend); - if (hud->text.num_vertices) { - cso_set_vertex_buffers(cso, cso_get_aux_vertex_buffer_slot(cso), 1, - &hud->text.vbuf); - cso_set_fragment_shader_handle(hud->cso, hud->fs_text); - cso_draw_arrays(cso, PIPE_PRIM_QUADS, 0, hud->text.num_vertices); - } - pipe_resource_reference(&hud->text.vbuf.buffer.resource, NULL); - /* draw the rest */ + cso_set_blend(cso, &hud->alpha_blend); cso_set_rasterizer(cso, &hud->rasterizer_aa_lines); LIST_FOR_EACH_ENTRY(pane, &hud->pane_list, head) { if (pane) @@ -678,7 +706,10 @@ hud_stop_queries(struct hud_context *hud, struct pipe_context *pipe) } } - hud_pane_accumulate_vertices(hud, pane); + if (hud->simple) + hud_pane_accumulate_vertices_simple(hud, pane); + else + hud_pane_accumulate_vertices(hud, pane); } /* unmap the uploader's vertex buffer before drawing */ @@ -842,6 +873,7 @@ hud_pane_update_dyn_ceiling(struct hud_graph *gr, struct hud_pane *pane) static struct hud_pane * hud_pane_create(struct hud_context *hud, unsigned x1, unsigned y1, unsigned x2, unsigned y2, + unsigned y_simple, unsigned period, uint64_t max_value, uint64_t ceiling, boolean dyn_ceiling, boolean sort_items) { @@ -855,6 +887,7 @@ hud_pane_create(struct hud_context *hud, pane->y1 = y1; pane->x2 = x2; pane->y2 = y2; + pane->y_simple = y_simple; pane->inner_x1 = x1 + 1; pane->inner_x2 = x2 - 1; pane->inner_y1 = y1 + 1; @@ -1156,7 +1189,7 @@ hud_parse_env_var(struct hud_context *hud, struct pipe_screen *screen, char name_a[256], s[256]; char *name; struct hud_pane *pane = NULL; - unsigned x = 10, y = 10; + unsigned x = 10, y = 10, y_simple = 10; unsigned width = 251, height = 100; unsigned period = 500 * 1000; /* default period (1/2 second) */ uint64_t ceiling = UINT64_MAX; @@ -1166,6 +1199,11 @@ hud_parse_env_var(struct hud_context *hud, struct pipe_screen *screen, boolean sort_items = false; const char *period_env; + if (util_strncmp(env, "simple,", 7) == 0) { + hud->simple = true; + env += 7; + } + /* * The GALLIUM_HUD_PERIOD env var sets the graph update rate. * The env var is in seconds (a float). @@ -1194,8 +1232,8 @@ hud_parse_env_var(struct hud_context *hud, struct pipe_screen *screen, column_width = width > column_width ?
