From b9abc6139a310677a37754ea7172d976dbf56979 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Kristian=20H=C3=B8gsberg?= Date: Thu, 9 Sep 2010 12:59:14 -0400 Subject: [PATCH] glapi: Implement optional dispatch logging There's a useful feature buried in glapi to log all API calls to stderr. Unfortunately it requires editing the code and then it's enabled unconditionally for that build. This patch builds in API logging for debug builds and makes it run-time switchable by setting MESA_DEBUG=dispatch. --- src/mapi/glapi/glapi.h | 8 ++- src/mapi/glapi/glapi_dispatch.c | 80 ++++++++++++++++++++------ src/mesa/drivers/dri/common/dri_test.c | 12 ++++ src/mesa/main/context.c | 24 +++++++- src/mesa/main/context.h | 3 + src/mesa/main/debug.c | 6 +- src/mesa/main/dlist.c | 8 +-- src/mesa/main/mtypes.h | 3 +- 8 files changed, 119 insertions(+), 25 deletions(-) diff --git a/src/mapi/glapi/glapi.h b/src/mapi/glapi/glapi.h index a0bb0781063..2fa580283e8 100644 --- a/src/mapi/glapi/glapi.h +++ b/src/mapi/glapi/glapi.h @@ -94,7 +94,7 @@ _GLAPI_EXPORT extern __thread void * _glapi_tls_Context _GLAPI_EXPORT extern const struct _glapi_table *_glapi_Dispatch;
