With pending\ncode like hw-breakpoints support the \u0027counter\u0027 name is less and\nless appropriate.\n\nAll in one, we\u0027ve decided to rename the subsystem to \u0027performance\nevents\u0027 and to propagate this rename through all fields, variables\nand API names. (in an ABI compatible fashion)\n\nThe word \u0027event\u0027 is also a bit shorter than \u0027counter\u0027 - which makes\nit slightly more convenient to write/handle as well.\n\nThanks goes to Stephane Eranian who first observed this misnomer and\nsuggested a rename.\n\nUser-space tooling and ABI compatibility is not affected - this patch\nshould be function-invariant. (Also, defconfigs were not touched to\nkeep the size down.)\n\nThis patch has been generated via the following script:\n\n FILES\u003d$(find * -type f | grep -vE \u0027oprofile|[^K]config\u0027)\n\n sed -i \\\n -e \u0027s/PERF_EVENT_/PERF_RECORD_/g\u0027 \\\n -e \u0027s/PERF_COUNTER/PERF_EVENT/g\u0027 \\\n -e \u0027s/perf_counter/perf_event/g\u0027 \\\n -e \u0027s/nb_counters/nb_events/g\u0027 \\\n -e \u0027s/swcounter/swevent/g\u0027 \\\n -e \u0027s/tpcounter_event/tp_event/g\u0027 \\\n $FILES\n\n for N in $(find . -name perf_counter.[ch]); do\n M\u003d$(echo $N | sed \u0027s/perf_counter/perf_event/g\u0027)\n mv $N $M\n done\n\n FILES\u003d$(find . -name perf_event.*)\n\n sed -i \\\n -e \u0027s/COUNTER_MASK/REG_MASK/g\u0027 \\\n -e \u0027s/COUNTER/EVENT/g\u0027 \\\n -e \u0027s/\\\u003cevent\\\u003e/event_id/g\u0027 \\\n -e \u0027s/counter/event/g\u0027 \\\n -e \u0027s/Counter/Event/g\u0027 \\\n $FILES\n\n... to keep it as correct as possible. This script can also be\nused by anyone who has pending perfcounters patches - it converts\na Linux kernel tree over to the new naming. We tried to time this\nchange to the point in time where the amount of pending patches\nis the smallest: the end of the merge window.\n\nNamespace clashes were fixed up in a preparatory patch - and some\nstylistic fallout will be fixed up in a subsequent patch.\n\n( NOTE: \u0027counters\u0027 are still the proper terminology when we deal\n with hardware registers - and these sed scripts are a bit\n over-eager in renaming them. I\u0027ve undone some of that, but\n in case there\u0027s something left where \u0027counter\u0027 would be\n better than \u0027event\u0027 we can undo that on an individual basis\n instead of touching an otherwise nicely automated patch. )\n\nSuggested-by: Stephane Eranian \u003ceranian@google.com\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nAcked-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nReviewed-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: David Howells \u003cdhowells@redhat.com\u003e\nCc: Kyle McMartin \u003ckyle@mcmartin.ca\u003e\nCc: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nCc: \"David S.

In particular\n it doesn\u0027t set the \"PMU in use\" flag.\n\nThis fixes the problem by arranging for ppc_enable_pmcs to always set\nthe \"PMU in use\" flag. It makes the perf_counter code call\nppc_enable_pmcs also rather than calling the lower-level function\ndirectly, and removes the setting of the \"PMU in use\" flag from\npseries_lpar_enable_pmcs, since that is now done in its caller.\n\nThis also removes the declaration of pasemi_enable_pmcs because it\nisn\u0027t defined anywhere.\n\nReported-by: Maynard Johnson \u003cmpjohn@us.ibm.com\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: \u003cstable@kernel.org)\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "757cbd46d11cfa7506b7dd5dd6657ae645bf6a17", "tree": "e8d13af7e6fcf5ef34f24dc4f2538b9f1f31d4c1", "parents": [ "8708d002c416b8bf87351bc626d15d7407896edb" ], "author": { "name": "Kumar Gala", "email": "galak@kernel.crashing.org", "time": "Tue Sep 08 17:38:52 2009 +0000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Fri Sep 11 11:27:57 2009 +1000" }, "message": "powerpc/85xx: Fix SMP compile error and allow NULL for smp_ops\n\nThe following commit introduced a compile error since it removed\nthe implementation of smp_85xx_basic_setup:\n\ncommit 77c0a700c1c292edafa11c1e52821ce4636f81b0\nAuthor: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nDate: Fri Aug 28 14:25:04 2009 +1000\n\n powerpc: Properly start decrementer on BookE secondary CPUs\n\nMake it so that smp_ops probe() and setup_cpu() can be set to NULL.\n\nSigned-off-by: Kumar Gala \u003cgalak@kernel.crashing.org\u003e\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "6e19314cc98ab9ccc22c30d1c414984ac6de5ce2", "tree": "2e83662e5e8cc1a0c30bba06008fe1b955c94cd5", "parents": [ "fe14acd4e7c8178dfb172c1e7a88356657378128" ], "author": { "name": "Mike Mason", "email": "mmlnx@us.ibm.com", "time": "Thu Jul 30 15:42:39 2009 -0700" }, "committer": { "name": "Jesse Barnes", "email": "jbarnes@virtuousgeek.org", "time": "Wed Sep 09 13:29:41 2009 -0700" }, "message": "PCI/powerpc: support PCIe fundamental reset\n\nBy default, the EEH framework on powerpc does what\u0027s known as a \"hot\nreset\" during recovery of a PCI Express device.

However, I don\u0027t expect the code to be more bloated than\nit already was in that area due to that change.\n\nI could boast that this brings proper enforcing of per-page execute\npermissions to all BookE and 40x but in fact, we\u0027ve had that now for\nsome time as a side effect of my previous rework in that area (and\nI didn\u0027t even know it :-) We would only enable execute permission if\nthe page was cache clean and we would only cache clean it if we took\nand exec fault. Since we now enforce that the later only work if\nVM_EXEC is part of the VMA flags, we de-fact already enforce per-page\nexecute permissions...
