From 822b2481ffc0d3e2ca9d24e9443634af2760777c Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 13 Feb 2008 10:34:20 -0800 Subject: [intel] Fix 965 rendering with non-TTM by merging intel_ioctl between 915/965. The 965 path wasn't setting pClipRects for batch submission since it didn't want kernel cliprect handling before. The 915 path also grew the INTEL_NO_HW=1 option for testing just driver overhead. --- src/mesa/drivers/dri/i965/intel_ioctl.c | 201 +------------------------------- 1 file changed, 1 insertion(+), 200 deletions(-) mode change 100644 => 120000 src/mesa/drivers/dri/i965/intel_ioctl.c (limited to 'src/mesa/drivers/dri/i965') diff --git a/src/mesa/drivers/dri/i965/intel_ioctl.c b/src/mesa/drivers/dri/i965/intel_ioctl.c deleted file mode 100644 index f0ba59dcb2..0000000000 --- a/src/mesa/drivers/dri/i965/intel_ioctl.c +++ /dev/null @@ -1,200 +0,0 @@ -/************************************************************************** - * - * Copyright 2003 Tungsten Graphics, Inc., Cedar Park, Texas. - * 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 -#include -#include -#include - -#include "mtypes.h" -#include "context.h" -#include "swrast/swrast.h" - -#include "intel_context.h" -#include "intel_ioctl.h" -#include "intel_batchbuffer.h" -#include "intel_blit.h" -#include "intel_regions.h" -#include "drm.h" -#include "dri_bufmgr.h" -#include "intel_bufmgr_ttm.h" -#include "i915_drm.h" - -int intelEmitIrqLocked( struct intel_context *intel ) -{ - int seq = 1; - - if (!intel->no_hw) { - drmI830IrqEmit ie; - int ret; - /* - assert(((*(int *)intel->driHwLock) & ~DRM_LOCK_CONT) == - (DRM_LOCK_HELD|intel->hHWContext)); - */ - ie.irq_seq = &seq; - - ret = drmCommandWriteRead( intel->driFd, - DRM_I830_IRQ_EMIT, - &ie, sizeof(ie) ); - if ( ret ) { - fprintf( stderr, "%s: drmI830IrqEmit: %d\n", __FUNCTION__, ret ); - exit(1); - } - - if (0) - fprintf(stderr, "%s --> %d\n", __FUNCTION__, seq ); - } - - return seq; -} - -void intelWaitIrq( struct intel_context *intel, int seq ) -{ - if (!intel->no_hw) { - drmI830IrqWait iw; - int ret, lastdispatch; - volatile drmI830Sarea *sarea = intel->sarea; - - if (0) - fprintf(stderr, "%s %d\n", __FUNCTION__, seq ); - - iw.irq_seq = seq; - - do { - lastdispatch = sarea->last_dispatch; - ret = drmCommandWrite( intel->driFd, - DRM_I830_IRQ_WAIT, &iw, sizeof(iw) ); - - /* This seems quite often to return before it should!?! - */ - } while (ret == -EAGAIN || - ret == -EINTR || - (ret == -EBUSY && lastdispatch != sarea->last_dispatch) || - (ret == 0 && seq > sarea->last_dispatch) || - (ret == 0 && sarea->last_dispatch - seq >= (1 << 24))); - - if ( ret ) { - fprintf( stderr, "%s: drmI830IrqWait: %d\n", __FUNCTION__, ret ); - - exit(1); - } - } -} - - -void intel_batch_ioctl( struct intel_context *intel, - GLuint start_offset, - GLuint used, - GLboolean ignore_cliprects, - GLboolean allow_unlock ) -{ - drmI830BatchBuffer batch; - - assert(intel->locked); - assert(used); - - if (0) - fprintf(stderr, "%s used %d offset %x..%x\n", - __FUNCTION__, - used, - start_offset, - start_offset + used); - - batch.start = start_offset; - batch.used = used; - batch.cliprects = NULL; - batch.num_cliprects = 0; - batch.DR1 = 0; - batch.DR4 = 0; - - if (INTEL_DEBUG & DEBUG_DMA) - fprintf(stderr, "%s: 0x%x..0x%x\n", - __FUNCTION__, - batch.start, - batch.start + batch.used * 4); - - if (!intel->no_hw) { - if (drmCommandWrite (intel->driFd, DRM_I830_BATCHBUFFER, &batch, - sizeof(batch))) { - fprintf(stderr, "DRM_I830_BATCHBUFFER: %d\n", -errno); - UNLOCK_HARDWARE(intel); - exit(1); - } - } -} - -void -intel_exec_ioctl(struct intel_context *intel, - GLuint used, - GLboolean ignore_cliprects, GLboolean allow_unlock, - void *start, GLuint count, dri_fence **fence) -{ - struct drm_i915_execbuffer execbuf; - dri_fence *fo; - int i; - - assert(intel->locked); - assert(used); - - if (*fence) { - dri_fence_unreference(*fence); - } - - memset(&execbuf, 0, sizeof(execbuf)); - - execbuf.num_buffers = count; - execbuf.batch.used = used; - execbuf.batch.cliprects = intel->pClipRects; - execbuf.batch.num_cliprects = ignore_cliprects ?
