Template Version: @(#)sac_nextcase %I% %G% SMI 1. Introduction 1.1. Project/Component Working Name: Xserver provider for DTrace 1.2. Name of Document Author/Supplier: Author: Alan Coopersmith 1.3 Date of This Document: 30 October, 2006 4. Technical Description Xserver provider for DTrace =========================== This case introduces a User-land Statically Defined Tracing (USDT) DTrace provider for X11 servers. This provider instruments various points in the X server, to allow tracing what client applications are up to. These probes will be included in the main X server applications shipped in the Solaris X Consolidation: Xorg, Xsun, Xprt, Xnest, Xvfb. Since this case only adds functionality and makes no visible changes to existing interfaces, it seeks a Patch release binding. Descriptions of the probes and their arguments are in the Xserver-probes.html file in the case materials. [For those reading this outside the Sun firewall, you can reference the copy at http://people.freedesktop.org/~alanc/dtrace/ now, or the case materials should be automatically mirrored to the case directory in the ARC community on opensolaris.org shortly.] Where possible, data formats and structures used are taken directly from the X11 Protocol wire formats, which are well defined and have been a stable standard interface for over 20 years. The probe definitions are annotated with these stability levels (the stability facility in DTrace still uses the previous stability taxonomy names): #pragma D attributes Unstable/Unstable/Common provider Xserver provider #pragma D attributes Private/Private/Unknown provider Xserver module #pragma D attributes Private/Private/Unknown provider Xserver function #pragma D attributes Unstable/Unstable/Common provider Xserver name #pragma D attributes Unstable/Unstable/Common provider Xserver args Imported Interfaces: -------------------- X11 Protocol, Revision 6.7 Stable X.Org Standard User-land Statically Defined Tracing (USDT) Evolving PSARC 2004/624 Exported Interfaces: -------------------- Xserver provider Uncommitted Xserver probe names & data Uncommitted Xserver binary file names & function names which may be exposed via these probes Project Private 6.
