From 9724dc1ac7ddd6f547a8aa6d57fa51ed1040db3a Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Fri, 9 Nov 2007 15:05:56 -0800 Subject: [i915] Remove old frontbuffer rotation hack. This was replaced in previous releases of xserver/dri/libGL by reporting the damage to the frontbuffer so that the server and driver could handle it appropriately. --- src/mesa/drivers/dri/i915/Makefile | 1 - src/mesa/drivers/dri/i915/i830_context.h | 4 - src/mesa/drivers/dri/i915/i915_metaops.c | 1 - src/mesa/drivers/dri/i915/intel_context.c | 46 +----- src/mesa/drivers/dri/i915/intel_context.h | 20 +-- src/mesa/drivers/dri/i915/intel_rotate.c | 237 ------------------------------ src/mesa/drivers/dri/i915/intel_rotate.h | 39 ----- 7 files changed, 5 insertions(+), 343 deletions(-) delete mode 100644 src/mesa/drivers/dri/i915/intel_rotate.c delete mode 100644 src/mesa/drivers/dri/i915/intel_rotate.h (limited to 'src/mesa/drivers/dri/i915') diff --git a/src/mesa/drivers/dri/i915/Makefile b/src/mesa/drivers/dri/i915/Makefile index ae96ddda0a..bff09ee842 100644 --- a/src/mesa/drivers/dri/i915/Makefile +++ b/src/mesa/drivers/dri/i915/Makefile @@ -46,7 +46,6 @@ DRIVER_SOURCES = \ intel_context.c \ intel_decode.c \ intel_ioctl.c \ - intel_rotate.c \ intel_screen.c \ intel_span.c \ intel_state.c \ diff --git a/src/mesa/drivers/dri/i915/i830_context.h b/src/mesa/drivers/dri/i915/i830_context.h index 9397fa45b5..a298c1407d 100644 --- a/src/mesa/drivers/dri/i915/i830_context.h +++ b/src/mesa/drivers/dri/i915/i830_context.h @@ -196,10 +196,6 @@ extern void i830InitState(struct i830_context *i830); */ extern void i830InitMetaFuncs(struct i830_context *i830); -extern void -i830RotateWindow(struct intel_context *intel, __DRIdrawablePrivate * dPriv, - GLuint srcBuf); - /*====================================================================== * Inline conversion functions.
