From 10c62bf0683437672c83339138a6802d56aeca8f Mon Sep 17 00:00:00 2001 From: Brian Date: Wed, 7 Nov 2007 16:07:17 -0700 Subject: Remove context dependencies in winsys layer. The winsys object is now per-screen and shared by multiple contexts. The regionPool is now part of the i915 winsys layer. The winsys wait_idle() and flush_frontbuffer() funcs will get more attention... --- src/mesa/drivers/dri/intel_winsys/intel_context.c | 11 +++-- src/mesa/drivers/dri/intel_winsys/intel_screen.c | 12 ++--- src/mesa/drivers/dri/intel_winsys/intel_screen.h | 3 +- src/mesa/drivers/dri/intel_winsys/intel_winsys.h | 5 ++- .../drivers/dri/intel_winsys/intel_winsys_pipe.c | 52 +++++++++++----------- src/mesa/pipe/p_context.h | 2 + src/mesa/pipe/p_winsys.h | 5 ++- src/mesa/pipe/xlib/xm_winsys.c | 2 +- src/mesa/state_tracker/st_cb_flush.c | 5 ++- 9 files changed, 51 insertions(+), 46 deletions(-) (limited to 'src/mesa') diff --git a/src/mesa/drivers/dri/intel_winsys/intel_context.c b/src/mesa/drivers/dri/intel_winsys/intel_context.c index 88551bc3a3..47be72b233 100644 --- a/src/mesa/drivers/dri/intel_winsys/intel_context.c +++ b/src/mesa/drivers/dri/intel_winsys/intel_context.c @@ -143,7 +143,6 @@ intelCreateContext(const __GLcontextModes * visual, int fthrottle_mode;
