Both busy_ioctl and the new wait_ioct need to do the same dance (or at least should). Some slight changes: - busy_ioctl now unconditionally checks for olr. Before emitting a require flush would have prevent the olr check and hence required a second call to the busy ioctl to really emit the request. - the timeout wait now also retires request. Not really required for abi-reasons, but makes a notch more sense imo. I've tested this by pimping the i-g-t test some more and also checking the polling behviour of the wait_rendering_timeout ioctl versus what busy_ioctl returns. v2: Too many people complained about unplug, new color is flush_active. v3: Kill the comment about the unplug moniker. v4: s/un-active/inactive/ Reviewed-by: Ben Widawsky <ben@bwidawsk.net> Signed-Off-by: Daniel Vetter <daniel.vetter@ffwll.ch> |

************************************************************ * For the very latest on DRI development, please see: * * http://dri.freedesktop.org/ * ************************************************************ The Direct Rendering Manager (drm) is a device-independent kernel-level device driver that provides support for the XFree86 Direct Rendering Infrastructure (DRI). The DRM supports the Direct Rendering Infrastructure (DRI) in four major ways: 1. The DRM provides synchronized access to the graphics hardware via the use of an optimized two-tiered lock. 2. The DRM enforces the DRI security policy for access to the graphics hardware by only allowing authenticated X11 clients access to restricted regions of memory. 3. The DRM provides a generic DMA engine, complete with multiple queues and the ability to detect the need for an OpenGL context switch. 4. The DRM is extensible via the use of small device-specific modules that rely extensively on the API exported by the DRM module. Documentation on the DRI is available from: http://dri.freedesktop.org/wiki/Documentation http://sourceforge.net/project/showfiles.php?group_id=387 http://dri.sourceforge.net/doc/ For specific information about kernel-level support, see: The Direct Rendering Manager, Kernel Support for the Direct Rendering Infrastructure http://dri.sourceforge.net/doc/drm_low_level.html Hardware Locking for the Direct Rendering Infrastructure http://dri.sourceforge.net/doc/hardware_locking_low_level.html A Security Analysis of the Direct Rendering Infrastructure http://dri.sourceforge.net/doc/security_low_level.html
