      "message": "[POWERPC] cell: Add oprofile support\n\nAdd PPU event-based and cycle-based profiling support to Oprofile for Cell.\n\nOprofile is expected to collect data on all CPUs simultaneously.\nHowever, there is one set of performance counters per node.  There are\ntwo hardware threads or virtual CPUs on each node.  Hence, OProfile must\nmultiplex in time the performance counter collection on the two virtual\nCPUs.\n\nThe multiplexing of the performance counters is done by a virtual\ncounter routine.  Initially, the counters are configured to collect data\non the even CPUs in the system, one CPU per node.  In order to capture\nthe PC for the virtual CPU when the performance counter interrupt occurs\n(the specified number of events between samples has occurred), the even\nprocessors are configured to handle the performance counter interrupts\nfor their node.  The virtual counter routine is called via a kernel\ntimer after the virtual sample time.  The routine stops the counters,\nsaves the current counts, loads the last counts for the other virtual\nCPU on the node, sets interrupts to be handled by the other virtual CPU\nand restarts the counters, the virtual timer routine is scheduled to run\nagain.  The virtual sample time is kept relatively small to make sure\nsampling occurs on both CPUs on the node with a relatively small\ngranularity.  Whenever the counters overflow, the performance counter\ninterrupt is called to collect the PC for the CPU where data is being\ncollected.\n\nThe oprofile driver relies on a firmware RTAS call to setup the debug bus\nto route the desired signals to the performance counter hardware to be\ncounted.  The RTAS call must set the routing registers appropriately in\neach of the islands to pass the signals down the debug bus as well as\nrouting the signals from a particular island onto the bus.  There is a\nsecond firmware RTAS call to reset the debug bus to the non pass thru\nstate when the counters are not in use.\n\nSigned-off-by: Carl Love \u003ccarll@us.ibm.com\u003e\nSigned-off-by: Maynard Johnson \u003cmpjohn@us.ibm.com\u003e\nSigned-off-by: Arnd Bergmann \u003carnd.bergmann@de.ibm.com\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n"
