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" }, { "commit": "0443bbd3d8496f9c2bc3e8c9d1833c6638722743", "tree": "7166aeb19de3d4cc538c7153843e009a5a33f32b", "parents": [ "e4f6948cfc8b9626022db0f93e7cf2ce5c0998cd" ], "author": { "name": "Kevin Corry", "email": "kevcorry@us.ibm.com", "time": "Mon Nov 20 18:45:15 2006 +0100" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Mon Dec 04 20:40:12 2006 +1100" }, "message": "[POWERPC] cell: Add routines for managing PMU interrupts\n\nThe following routines are added to arch/powerpc/platforms/cell/pmu.c:\n cbe_clear_pm_interrupts()\n cbe_enable_pm_interrupts()\n cbe_disable_pm_interrupts()\n cbe_query_pm_interrupts()\n cbe_pm_irq()\n cbe_init_pm_irq()\n\nThis also adds a routine in arch/powerpc/platforms/cell/interrupt.c and\nsome macros in cbe_regs.h to manipulate the IIC_IR register:\n iic_set_interrupt_routing()\n\nSigned-off-by: Kevin Corry \u003ckevcorry@us.ibm.com\u003e\nSigned-off-by: Carl Love \u003ccarll@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" }, { "commit": "e4f6948cfc8b9626022db0f93e7cf2ce5c0998cd", "tree": "ffc39ea93cbae7bb391678b42958e19252867c44", "parents": [ "c93dfa0766bae3c92ec8311bddbbf16b8e661f59" ], "author": { "name": "Kevin Corry", "email": "kevcorry@us.ibm.com", "time": "Mon Nov 20 18:45:14 2006 +0100" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Mon Dec 04 20:40:11 2006 +1100" }, "message": "[POWERPC] cell: Move PMU-related stuff to include/asm-powerpc/cell-pmu.h\n\nMove some PMU-related macros and function prototypes from cbe_regs.h\nand pmu.h in arch/powerpc/platforms/cell/ to a new header at\ninclude/asm-powerpc/cell-pmu.h\n\nThis is cleaner to use from the oprofile code, since that sits in\narch/powerpc/oprofile, not in the cell platform directory.\n\nSigned-off-by: Kevin Corry \u003ckevcorry@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" }, { "commit": "b9e3bd774bb1a90fee9b90f461a51e4ba295fe6d", "tree": "1df839981e28241d66f9bc5abe56f99476ef2a3f", "parents": [ "9b5047e249f429722d0adc54cb5ef051bd3d685c" ], "author": { "name": "Dwayne Grant McConnell", "email": "decimal@us.ibm.com", "time": "Mon Nov 20 18:44:58 2006 +0100" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Mon Dec 04 20:39:45 2006 +1100" }, "message": "[POWERPC] spufs: Add /lslr, /dma_info and /proxydma files\n\nThe /lslr file gives read access to the SPU_LSLR register in hex; 0x3fff\nfor example The /dma_info file provides read access to the SPU Command\nQueue in a binary format.

On the \"breaks\" side of things,\ndrivers uisng of_platform_device(s) need to include asm/of_platform.h now\nand of_(un)register_driver is now of_(un)register_platform_driver.\n\nIn addition to a few utility functions to locate of_platform_device(s),\nthe main new addition is of_platform_bus_probe() which allows the platform\ncode to trigger an automatic creation of of_platform_devices for a whole\ntree of devices.\n\nThe function acts based on the type of the various \"parent\" devices encountered\nfrom a provided root, using either a default known list of bus types that can be\n\"probed\" or a passed-in list. It will only register devices on busses matching\nthat list, which mean that typically, it will not register PCI devices, as\nexpected (since they will be picked up by the PCI layer).\n\nThis will be used by Cell platforms using 4xx-type IOs in the Axon bridge\nand can be used by any embedded-type device as well.\n\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n" }, { "commit": "a959ff56bbf07954ea4fa1cf72f99a38795eadb3", "tree": "85bd54ccfe77a9508a6cf2763d296ff988b9764f", "parents": [ "fbf0274e43b7e17ee740fee2d693932be093d56d" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Sat Nov 11 17:24:56 2006 +1100" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Mon Dec 04 16:08:41 2006 +1100" }, "message": "[POWERPC] Improve MPIC driver auto-configuration from DT\n\nThis patch applies on top of the MPIC DCR support.

On the FRV arch, removing the regs parameter\nfrom all the genirq function results in a 20% speed up of the IRQ exit path\n(ie: from leaving timer_interrupt() to leaving do_IRQ()).\n\nWhere appropriate, an arch may override the generic storage facility and do\nsomething different with the variable. On FRV, for instance, the address is\nmaintained in GR28 at all times inside the kernel as part of general exception\nhandling.\n\nHaving looked over the code, it appears that the parameter may be handed down\nthrough up to twenty or so layers of functions. Consider a USB character\ndevice attached to a USB hub, attached to a USB controller that posts its\ninterrupts through a cascaded auxiliary interrupt controller. A character\ndevice driver may want to pass regs to the sysrq handler through the input\nlayer which adds another few layers of parameter passing.\n\nI\u0027ve build this code with allyesconfig for x86_64 and i386. I\u0027ve runtested the\nmain part of the code on FRV and i386, though I can\u0027t test most of the drivers.\nI\u0027ve also done partial conversion for powerpc and MIPS - these at least compile\nwith minimal configurations.\n\nThis will affect all archs. Mostly the changes should be relatively easy.\nTake do_IRQ(), store the regs pointer at the beginning, saving the old one:\n\n\tstruct pt_regs *old_regs \u003d set_irq_regs(regs);\n\nAnd put the old one back at the end:\n\n\tset_irq_regs(old_regs);\n\nDon\u0027t pass regs through to generic_handle_irq() or __do_IRQ().\n\nIn timer_interrupt(), this sort of change will be necessary:\n\n\t-\tupdate_process_times(user_mode(regs));\n\t-\tprofile_tick(CPU_PROFILING, regs);\n\t+\tupdate_process_times(user_mode(get_irq_regs()));\n\t+\tprofile_tick(CPU_PROFILING);\n\nI\u0027d like to move update_process_times()\u0027s use of get_irq_regs() into itself,\nexcept that i386, alone of the archs, uses something other than user_mode().\n\nSome notes on the interrupt handling in the drivers:\n\n (*) input_dev() is now gone entirely. The regs pointer is no longer stored in\n the input_dev struct.\n\n (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking.
