as an added benefit,\nthe Python binaries may be installed in non-standard locations\nwithout the need for updating any PATH variable.\n\nThis commit adds the ability to set PYTHON and/or PYTHON_CONFIG\neither as environment variables or as make variables on the\ncommand line; the paths may be relative, and usually only PYTHON\nis necessary in order for PYTHON_CONFIG to be defined implicitly.\nSome rudimentary error checking is performed when the user\nexplicitly specifies a value for any of these variables.\n\nIn addition, this commit introduces significantly robust makefile\ninfrastructure for working with paths and communicating with the\nshell;

we only know the name of the non contiguous kernel ranges in\nthe address space when reading the symbol information from the ELF symtab in\nvmlinux.\n\nThe /proc/kallsyms file lack this, we only notice they are separate because\nthere are modules after the kernel and after that more kernel functions, so we\nneed to have a module rbtree backed by the module .ko path to get symtabs in\nthe vmlinux case.\n\nThe tool uses it to match by address to emit appropriate warning, but don\u0027t\nconsiders this fatal.\n\nThe .init.text and .exit.text ines, of course, aren\u0027t in kallsyms, so I left\nthese cases just as extra info in verbose mode.\n\nThe end of the sections also aren\u0027t in kallsyms, so we the symbols layer does\nanother pass and sets the end addresses as the next map start minus one, which\nsometimes pads, causing harmless mismatches.\n\nBut at least the symbols match, tested it by copying /proc/kallsyms to\n/tmp/kallsyms and doing changes to see if they were detected.\n\nThis first test also should serve as a first stab at documenting the\nsymbol library by providing a self contained example that exercises it\ntogether with comments about what is being done.\n\nMore tests to check if actions done on a monitored app, like doing mmaps, etc,\nmakes the kernel generate the expected events should be added next.\n\nCc: Frédéric Weisbecker

These tools ask\nfor the number of online cpus with sysconf(_SC_NPROCESSORS_ONLN)\nand then try to create events for cpus 0, 1, ..., N-1.\n\nThis creates problems for systems where the online cpus are\nnumbered sparsely. For example, a POWER6 system in\nsingle-threaded mode (i.e. only running 1 hardware thread per\ncore) will have only even-numbered cpus online.\n\nThis fixes the problem by reading the /sys/devices/system/cpu/online\nfile to find out which cpus are online. The code that does that is in\ntools/perf/util/cpumap.[ch], and consists of a read_cpu_map()\nfunction that sets up a cpumap[] array and returns the number of\nonline cpus. If /sys/devices/system/cpu/online can\u0027t be read or\ncan\u0027t be parsed successfully, it falls back to using sysconf to\nask how many cpus are online and sets up an identity map in cpumap[].\n\nThe perf record, perf stat and perf top code then calls\nread_cpu_map() in the system-wide monitoring case (instead of\nsysconf) and uses cpumap[] to get the cpu numbers to pass to\nperf_event_open.\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Anton Blanchard \u003canton@samba.org\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@infradead.org\u003e\nLKML-Reference: \u003c20100310093609.GA3959@brick.ozlabs.ibm.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "804b36068eccd8163ccea420c662fb5d1a21b141", "tree": "08837b6d7be24d56c30af2932e59fa1c23420396", "parents": [ "81cb8aa327b5923b38eccc795c8b7170be20b9ff" ], "author": { "name": "Masami Hiramatsu", "email": "mhiramat@redhat.com", "time": "Thu Feb 25 08:35:42 2010 -0500" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Feb 25 17:49:29 2010 +0100" }, "message": "perf probe: Use elfutils-libdw for analyzing debuginfo\n\nNewer gcc introduces newer \u0026 richer debuginfo, and only libdw\nin elfutils project can support it.

"perf record: Introduce a symtab cache\n\nNow a cache will be created in a ~/.debug debuginfo like\nhierarchy, so that at the end of a \u0027perf record\u0027 session all the\nbinaries (with build-ids) involved get collected and indexed by\ntheir build-ids, so that perf report can find them.\n\nThis is interesting when developing software where you want to\ndo a \u0027perf diff\u0027 with the previous build and opens avenues for\nlots more interesting tools, like a \u0027perf diff --graph\u0027 that\ntakes more than two binaries into account.\n\nTunables for collecting just the symtabs can be added if one\ndoesn\u0027t want to have the full binary, but having the full binary\nallows things like \u0027perf rerecord\u0027 or other tools that can\nre-run the tests by having access to the exact binary in some\nperf.data file, so it may well be interesting to keep the full\nbinary there.\n\nSpace consumption is minimised by trying to use hard links, a\n\u0027perf cache\u0027 tool to manage the space used, a la ccache is\nrequired to purge older entries.\n\nWith this in place it will be possible also to introduce new\ncommands, \u0027perf archive\u0027 and \u0027perf restore\u0027 (or some more\nsuitable and future proof names) to create a cpio/tar file with\nthe perf data and the files in the cache that _had_ perf hits of\ninterest.\n\nThere are more aspects to polish, like finding the right vmlinux\nfile to cache, etc, but this is enough for a first step.\n\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Frédéric Weisbecker
