From e433b73dd256577b022bf38c8499c7ea4eda9845 Mon Sep 17 00:00:00 2001 From: Zack Rusin Date: Tue, 22 Jun 2010 12:14:29 -0400 Subject: [PATCH] gallium: add a timestamp disjoint query allows application to not only request the frequency of the TIME_ELAPSED clock but also to detect if that frequency was consistent throughout the entire bracketed range of graphics commands. --- src/gallium/auxiliary/draw/draw_gs.c | 2 +- src/gallium/drivers/softpipe/sp_query.c | 14 +++++++++++++- src/gallium/include/pipe/p_defines.h | 8 +++++++- 3 files changed, 21 insertions(+), 3 deletions(-) diff --git a/src/gallium/auxiliary/draw/draw_gs.c b/src/gallium/auxiliary/draw/draw_gs.c index 881d8fc93ba..79a57a67f3e 100644 --- a/src/gallium/auxiliary/draw/draw_gs.c +++ b/src/gallium/auxiliary/draw/draw_gs.c @@ -39,7 +39,6 @@ #include "util/u_memory.h" #include "util/u_prim.h" -#define MAX_PRIM_VERTICES 6 /* fixme: move it from here */ #define MAX_PRIMITIVES 64 @@ -76,6 +75,7 @@ draw_gs_set_constants(struct draw_context *draw, const void *constants, unsigned size) { + /* noop */ } diff --git a/src/gallium/drivers/softpipe/sp_query.c b/src/gallium/drivers/softpipe/sp_query.c index 9328334c5c4..4ae69c1c2bd 100644 --- a/src/gallium/drivers/softpipe/sp_query.c +++ b/src/gallium/drivers/softpipe/sp_query.c @@ -59,7 +59,8 @@ softpipe_create_query(struct pipe_context *pipe, assert(type == PIPE_QUERY_OCCLUSION_COUNTER || type == PIPE_QUERY_TIME_ELAPSED || type == PIPE_QUERY_SO_STATISTICS || - type == PIPE_QUERY_GPU_FINISHED); + type == PIPE_QUERY_GPU_FINISHED || + type == PIPE_QUERY_TIMESTAMP_DISJOINT); sq = CALLOC_STRUCT( softpipe_query ); sq->type = type; @@ -93,6 +94,7 @@ softpipe_begin_query(struct pipe_context *pipe, struct pipe_query *q) break; case PIPE_QUERY_GPU_FINISHED: break; + case PIPE_QUERY_TIMESTAMP_DISJOINT: default: assert(0); break; @@ -123,6 +125,7 @@ softpipe_end_query(struct pipe_context *pipe, struct pipe_query *q) softpipe->so_stats.primitives_storage_needed; break; case PIPE_QUERY_GPU_FINISHED: + case PIPE_QUERY_TIMESTAMP_DISJOINT: break; default: assert(0); @@ -149,6 +152,15 @@ softpipe_get_query_result(struct pipe_context *pipe, case PIPE_QUERY_GPU_FINISHED: *result = TRUE; break; + case PIPE_QUERY_TIMESTAMP_DISJOINT: { + struct pipe_query_data_timestamp_disjoint td; + /*os_get_time is in microseconds*/ + td.frequency = 1000000; + td.disjoint = FALSE; + memcpy(vresult, &sq->so, + sizeof(struct pipe_query_data_timestamp_disjoint)); + } + break; default: *result = sq->end - sq->start; break; diff --git a/src/gallium/include/pipe/p_defines.h b/src/gallium/include/pipe/p_defines.h index b3a53c262de..3b87d998ceb 100644 --- a/src/gallium/include/pipe/p_defines.h +++ b/src/gallium/include/pipe/p_defines.h @@ -383,7 +383,8 @@ enum pipe_transfer_usage { #define PIPE_QUERY_TIME_ELAPSED 3 #define PIPE_QUERY_SO_STATISTICS 5 #define PIPE_QUERY_GPU_FINISHED 6 -#define PIPE_QUERY_TYPES 7 +#define PIPE_QUERY_TIMESTAMP_DISJOINT 7 +#define PIPE_QUERY_TYPES 8 /** @@ -508,6 +509,11 @@ struct pipe_query_data_so_statistics uint64_t num_primitives_written; uint64_t primitives_storage_needed; }; +struct pipe_query_data_timestamp_disjoint +{ + uint64_t frequency; + boolean disjoint; +}; #ifdef __cplusplus } -- 2.30.2
