What about libdrm? There was a fix put into 2.4.4 to prevent hangs if a wait occurred on a disabled pipe. You may also want to check out e57e39896049a045751201e912779872026fc741..39b4061bb9be540dfb51891e22c505bc235ec8a2 in the Mesa tree; they fix the case where at startup time an app may end up waiting on the wrong pipe. -- Jesse Barnes, Intel Open Source Technology Center ------------------------------------------------------------------------------ This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword -- _______________________________________________ Dri-devel mailing list Dri-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dri-devel
