This gets us\nstuck in a loop which we eventually break out of by throttling the PMU (there\nare regular throttle/unthrottle events in the log).\n\nIt looks like we aren\u0027t setting event-\u003ehw.last_period to something same and the\nfrequency to period calculations in perf are going haywire.\n\nWith the following patch we find the correct period after a few interrupts and\nstay there. I also see no more throttle events.\n\nSigned-off-by: Anton Blanchard \u003canton@samba.org\u003e\nAcked-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: linuxppc-dev@lists.ozlabs.org\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@ghostprotocols.net\u003e\nLKML-Reference: \u003c20110117161742.5feb3761@kryten\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "672c54466d24994eb9633f993862c89539504a42", "tree": "e08f17e5fa260676912eb9b7d2263d47d667fdec", "parents": [ "1b59be2a6cdcb5a12e18d8315c07c94a624de48f" ], "author": { "name": "Grant Likely", "email": "grant.likely@secretlab.ca", "time": "Thu Jan 13 15:36:09 2011 -0700" }, "committer": { "name": "Grant Likely", "email": "grant.likely@secretlab.ca", "time": "Sat Jan 15 22:01:58 2011 -0700" }, "message": "dt/flattree: Return virtual address from early_init_dt_alloc_memory_arch()\n\nThe physical address is never used by the device tree code when\nallocating memory for unflattening.

The new APIs are now clearly named to\ndistinguish \u0027core number\u0027 versus first and last \u0027logical cpu\nnumber\u0027 in that core.\n\nThe new APIs cpu_{first,last}_thread_sibling() work on\nlogical cpu numbers. While cpu_first_thread_of_core() and\ncpu_core_index_of_thread() work on core index.\n\nExample usage: (4 threads per core system)\n\ncpu_first_thread_sibling(5) \u003d 4\ncpu_last_thread_sibling(5) \u003d 7\ncpu_core_index_of_thread(5) \u003d 1\ncpu_first_thread_of_core(1) \u003d 4\n\ncpu_core_index_of_thread() is used in cpu_to_drc_index() in the\nmodule and cpu_first_thread_of_core() is used in\ndrc_index_to_cpu() in the module.\n\nMake API changes to few callers.

early_init_dt_scan_chosen_arch\n\nThis patch refactors the early init parsing of the chosen node so that\narchitectures aren\u0027t forced to provide an empty implementation of\nearly_init_dt_scan_chosen_arch. Instead, if an architecture wants to\ndo something different, it can either use a wrapper function around\nearly_init_dt_scan_chosen(), or it can replace it altogether.\n\nThis patch was written in preparation to adding device tree support to\nboth x86 ad MIPS.\n\nSigned-off-by: Grant Likely \u003cgrant.likely@secretlab.ca\u003e\nTested-by: David Daney \u003cddaney@caviumnetworks.com\u003e\n" }, { "commit": "7096d0422153ffcc2264eef652fc3a7bca3e6d3c", "tree": "2be6139f1e26acb4d0680e50a87623bc18938147", "parents": [ "bda80da469a93122121de601dd469ce1aaa6effa" ], "author": { "name": "Grant Likely", "email": "grant.likely@secretlab.ca", "time": "Wed Oct 20 11:45:13 2010 -0600" }, "committer": { "name": "Grant Likely", "email": "grant.likely@secretlab.ca", "time": "Thu Oct 21 11:10:10 2010 -0600" }, "message": "of/device: Rework to use common platform_device_alloc() for allocating devices\n\nThe current code allocates and manages platform_devices created from\nthe device tree manually.
