From f137f5c691f5bd97a8b7f881f1f6837bff0ebc7a Mon Sep 17 00:00:00 2001 From: Samuel Pitoiset Date: Fri, 4 Jul 2014 11:24:02 +0200 Subject: gallium: add pipe_screen::get_driver_query_group_info Driver queries are organized as a single hierarchy where queries are categorized into groups. Each group has a list of queries and a maximum number of queries that can be sampled. The list of available groups can be obtained using pipe_screen::get_driver_query_group_info. This will be used by GL_AMD_performance monitor. v2: add group type (CPU/GPU) Signed-off-by: Samuel Pitoiset Reviewed-by: Martin Peres --- src/gallium/include/pipe/p_defines.h | 14 ++++++++++++++ src/gallium/include/pipe/p_screen.h | 11 +++++++++++ 2 files changed, 25 insertions(+) (limited to 'src/gallium/include/pipe') diff --git a/src/gallium/include/pipe/p_defines.h b/src/gallium/include/pipe/p_defines.h index 67f48e42936..c1e660e899c 100644 --- a/src/gallium/include/pipe/p_defines.h +++ b/src/gallium/include/pipe/p_defines.h @@ -752,6 +752,12 @@ union pipe_color_union unsigned int ui[4]; }; +enum pipe_driver_query_group_type +{ + PIPE_DRIVER_QUERY_GROUP_TYPE_CPU = 0, + PIPE_DRIVER_QUERY_GROUP_TYPE_GPU = 1, +}; + struct pipe_driver_query_info { const char *name; @@ -760,6 +766,14 @@ struct pipe_driver_query_info boolean uses_byte_units; /* whether the result is in bytes */ }; +struct pipe_driver_query_group_info +{ + const char *name; + enum pipe_driver_query_group_type type; + unsigned max_active_queries; + unsigned num_queries; +}; + #ifdef __cplusplus } #endif diff --git a/src/gallium/include/pipe/p_screen.h b/src/gallium/include/pipe/p_screen.h index 21e7dd35ec0..98b2159defe 100644 --- a/src/gallium/include/pipe/p_screen.h +++ b/src/gallium/include/pipe/p_screen.h @@ -236,6 +236,17 @@ struct pipe_screen { unsigned index, struct pipe_driver_query_info *info); + /** + * Returns a driver-specific query group. + * + * If \p info is NULL, the number of available groups is returned. + * Otherwise, the driver query group at the specified \p index is returned + * in \p info.
