From: Marek Olšák Date: Fri, 28 Oct 2011 16:27:00 +0000 (+0200) Subject: r600g: only maintain the list of active queries X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e9b6f21a5054b2639a1dfc6401e4e9053dce5394;p=mesa.git r600g: only maintain the list of active queries And not all existing queries. The only reason we have that list is to be able to suspend and resume the active ones. This reduces looping over queries when suspending and resuming. The queries no longer have to track some of their states. --- diff --git a/src/gallium/drivers/r600/evergreen_hw_context.c b/src/gallium/drivers/r600/evergreen_hw_context.c index 3779dd480f8..72ec5630b9a 100644 --- a/src/gallium/drivers/r600/evergreen_hw_context.c +++ b/src/gallium/drivers/r600/evergreen_hw_context.c @@ -905,7 +905,7 @@ int evergreen_context_init(struct r600_context *ctx, struct r600_screen *screen) memset(ctx, 0, sizeof(struct r600_context)); ctx->screen = screen; - LIST_INITHEAD(&ctx->query_list); + LIST_INITHEAD(&ctx->active_query_list); /* init dirty list */ LIST_INITHEAD(&ctx->dirty); diff --git a/src/gallium/drivers/r600/r600.h b/src/gallium/drivers/r600/r600.h index ea9a2d658c2..f58549afb4d 100644 --- a/src/gallium/drivers/r600/r600.h +++ b/src/gallium/drivers/r600/r600.h @@ -179,7 +179,7 @@ struct r600_query { /* Count of new queries started in one stream without flushing */ unsigned queries_emitted; /* State flags */ - unsigned state; + boolean flushed; /* The buffer where query results are stored.
