From 98514e9959ae72d371590ca8301341404ce11c00 Mon Sep 17 00:00:00 2001 From: Christoph Haag Date: Fri, 14 Jul 2017 09:59:38 +0200 Subject: [PATCH] gallium/hud: use double values for all graphs MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The fps graph for example calculates the fps as double with small variations based on when query_new_value() is called, which causes many values to be truncated on the cast to uint64_t. The HUD internally stores the values as double, so just use double everywhere instead of fixing this with rounding. Using doubles also allows the hud to show small variations instead of being clamped to discrete values. v2: Don't print decimals in the dump file when not necessary Signed-off-by: Christoph Haag Signed-off-by: Marek Olšák --- src/gallium/auxiliary/hud/hud_context.c | 14 ++++++++++---- src/gallium/auxiliary/hud/hud_fps.c | 4 ++-- src/gallium/auxiliary/hud/hud_private.h | 4 ++-- 3 files changed, 14 insertions(+), 8 deletions(-) diff --git a/src/gallium/auxiliary/hud/hud_context.c b/src/gallium/auxiliary/hud/hud_context.c index 8172313605d..2deb48d18e7 100644 --- a/src/gallium/auxiliary/hud/hud_context.c +++ b/src/gallium/auxiliary/hud/hud_context.c @@ -204,7 +204,7 @@ hud_draw_string(struct hud_context *hud, unsigned x, unsigned y, } static void -number_to_human_readable(uint64_t num, enum pipe_driver_query_type type, +number_to_human_readable(double num, enum pipe_driver_query_type type, char *out) { static const char *byte_units[] = @@ -861,13 +861,19 @@ hud_pane_add_graph(struct hud_pane *pane, struct hud_graph *gr) } void -hud_graph_add_value(struct hud_graph *gr, uint64_t value) +hud_graph_add_value(struct hud_graph *gr, double value) { gr->current_value = value; value = value > gr->pane->ceiling ? gr->pane->ceiling : value; - if (gr->fd) - fprintf(gr->fd, "%" PRIu64 "\n", value); + if (gr->fd) { + if (fabs(value - lround(value)) > FLT_EPSILON) { + fprintf(gr->fd, "%f\n", value); + } + else { + fprintf(gr->fd, "%" PRIu64 "\n", (uint64_t) lround(value)); + } + } if (gr->index == gr->pane->max_num_vertices) { gr->vertices[0] = 0; diff --git a/src/gallium/auxiliary/hud/hud_fps.c b/src/gallium/auxiliary/hud/hud_fps.c index a360bc2ed04..8aa7a665a30 100644 --- a/src/gallium/auxiliary/hud/hud_fps.c +++ b/src/gallium/auxiliary/hud/hud_fps.c @@ -47,12 +47,12 @@ query_fps(struct hud_graph *gr) if (info->last_time) { if (info->last_time + gr->pane->period <= now) { - double fps = (uint64_t)info->frames * 1000000 / + double fps = ((uint64_t)info->frames) * 1000000 / (double)(now - info->last_time); info->frames = 0; info->last_time = now; - hud_graph_add_value(gr, (uint64_t) fps); + hud_graph_add_value(gr, fps); } } else { diff --git a/src/gallium/auxiliary/hud/hud_private.h b/src/gallium/auxiliary/hud/hud_private.h index 2b1717d2c4a..65baa8aa7e7 100644 --- a/src/gallium/auxiliary/hud/hud_private.h +++ b/src/gallium/auxiliary/hud/hud_private.h @@ -104,7 +104,7 @@ struct hud_graph { /* mutable variables */ unsigned num_vertices; unsigned index; /* vertex index being updated */ - uint64_t current_value; + double current_value; FILE *fd; }; @@ -139,7 +139,7 @@ struct hud_pane { /* core */ void hud_pane_add_graph(struct hud_pane *pane, struct hud_graph *gr); void hud_pane_set_max_value(struct hud_pane *pane, uint64_t value); -void hud_graph_add_value(struct hud_graph *gr, uint64_t value); +void hud_graph_add_value(struct hud_graph *gr, double value); /* graphs/queries */ struct hud_batch_query_context; -- 2.30.2
