From 1d060e36f248b2c1d2575d1e2cbd362b8345ae55 Mon Sep 17 00:00:00 2001 From: Jakob Bornecrantz Date: Tue, 3 Mar 2009 03:22:05 +0100 Subject: st/dri2: Add DRI2 a state tracker This was based of the unfinnished code that Keith Whitwell started on but never finnished. I moved the code from the glx directory because dri drivers can be used for more things then just glx. --- src/gallium/state_trackers/glx/dri/dri_lock.c | 90 --------------------------- 1 file changed, 90 deletions(-) delete mode 100644 src/gallium/state_trackers/glx/dri/dri_lock.c (limited to 'src/gallium/state_trackers/glx/dri/dri_lock.c') diff --git a/src/gallium/state_trackers/glx/dri/dri_lock.c b/src/gallium/state_trackers/glx/dri/dri_lock.c deleted file mode 100644 index b272ab55f3..0000000000 --- a/src/gallium/state_trackers/glx/dri/dri_lock.c +++ /dev/null @@ -1,90 +0,0 @@ -/************************************************************************** - * - * Copyright 2009 VMware, Inc. - * All Rights Reserved. - * - * Permission is hereby granted, free of charge, to any person obtaining a - * copy of this software and associated documentation files (the - * "Software"), to deal in the Software without restriction, including - * without limitation the rights to use, copy, modify, merge, publish, - * distribute, sub license, and/or sell copies of the Software, and to - * permit persons to whom the Software is furnished to do so, subject to - * the following conditions: - * - * The above copyright notice and this permission notice (including the - * next paragraph) shall be included in all copies or substantial portions - * of the Software. - * - * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS - * OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF - * MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT. - * IN NO EVENT SHALL TUNGSTEN GRAPHICS AND/OR ITS SUPPLIERS BE LIABLE FOR - * ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, - * TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE - * SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE. - * - **************************************************************************/ - - -#include "pipe/p_thread.h" -#include "dri_context.h" -#include "xf86drm.h" - -pipe_static_mutex( lockMutex ); - -static void -dri_contended_lock(struct dri_context *ctx) -{ - __DRIdrawablePrivate *dPriv = ctx->dPriv; - __DRIcontextPrivate *cPriv = ctx->cPriv; - __DRIscreenPrivate *sPriv = cPriv->driScreenPriv; - - drmGetLock(sPriv->fd, cPriv->hHWContext, 0); - - /* Perform round trip communication with server (including dropping - * and retaking the above lock) to update window dimensions: - */ - if (dPriv) - DRI_VALIDATE_DRAWABLE_INFO(sPriv, dPriv); -} - - -/* Lock the hardware and validate our state. - */ -void dri_lock_hardware( struct dri_context *ctx ) -{ - __DRIcontextPrivate *cPriv = ctx->cPriv; - __DRIscreenPrivate *sPriv = cPriv->driScreenPriv; - char __ret = 0; - - pipe_mutex_lock(lockMutex); - assert(!ctx->locked); - - DRM_CAS((drmLock *) &sPriv->pSAREA->lock, - cPriv->hHWContext, - (DRM_LOCK_HELD | cPriv->hHWContext), - __ret); - - if (__ret) - dri_contended_lock( ctx ); - - ctx->locked = TRUE; -} - - -/* Unlock the hardware using the global current context - */ -void dri_unlock_hardware( struct dri_context *ctx ) -{ - __DRIcontextPrivate *cPriv = ctx->cPriv; - __DRIscreenPrivate *sPriv = cPriv->driScreenPriv; - - assert(ctx->locked); - ctx->locked = FALSE; - - DRM_UNLOCK(sPriv->fd, - (drmLock *) &sPriv->pSAREA->lock, - cPriv->hHWContext); - - pipe_mutex_unlock(lockMutex); -} -- cgit v1.2.3
