perf config: Introduce perf_config_set class

2016-04-14T12:00:42+00:00

This infrastructure code was designed for upcoming features of 'perf config'. That collect config key-value pairs from user and system config files (i.e. user wide ~/.perfconfig and system wide $(sysconfdir)/perfconfig) to manage perf's configs.

perf config: Rework buildid_dir_command_config to perf_buildid_config

2016-03-30T14:14:09+00:00

To avoid repeated calling perf_config() remove buildid_dir_command_config() and add new perf_buildid_config into perf_default_config. Because perf_config() is already called with perf_default_config at main().

perf config: Add '--system' and '--user' options to select which config file is used

2016-02-12T13:54:46+00:00

The '--system' option means $(sysconfdir)/perfconfig and '--user' means $HOME/.perfconfig. If none is used, both system and user config file are read. E.g.: # perf config [] [options] With an specific config file: # perf config --user | --system or both user and system config file: # perf config Signed-off-by: Taeung Song Cc: Jiri Olsa Cc: Namhyung Kim Link: http://lkml.kernel.org/r/1455126685-32367-2-git-send-email-treeze.taeung@gmail.com Signed-off-by: Arnaldo Carvalho de Melo

perf subcmd: Create subcmd library

2015-12-17T17:27:14+00:00

Move the subcommand-related files from perf to a new library named libsubcmd.a. Since we're moving files anyway, go ahead and rename 'exec_cmd.*' to 'exec-cmd.*' to be consistent with the naming of all the other files.

perf tools: Introduce llvm config options

2015-08-07T13:16:59+00:00

This patch introduces [llvm] config section with 5 options. Following patches will use then to config llvm dynamica compiling. 'llvm-utils.[ch]' is introduced in this patch for holding all llvm/clang related stuffs. Example: [llvm] # Path to clang. If omit, search it from $PATH. clang-path = "/path/to/clang" # Cmdline template. Following line shows its default value. # Environment variable is used to passing options. # # *NOTE*: -D__KERNEL__ MUST appears before $CLANG_OPTIONS, # so user have a chance to use -U__KERNEL__ in $CLANG_OPTIONS # to cancel it. clang-bpf-cmd-template = "$CLANG_EXEC -D__KERNEL__ $CLANG_OPTIONS \ $KERNEL_INC_OPTIONS -Wno-unused-value \ -Wno-pointer-sign -working-directory \ $WORKING_DIR -c $CLANG_SOURCE -target \ bpf -O2 -o -" # Options passed to clang, will be passed to cmdline by # $CLANG_OPTIONS. clang-opt = "-Wno-unused-value -Wno-pointer-sign" # kbuild directory. If not set, use /lib/modules/`uname -r`/build. # If set to "" deliberately, skip kernel header auto-detector. kbuild-dir = "/path/to/kernel/build" # Options passed to 'make' when detecting kernel header options. kbuild-opts = "ARCH=x86_64" Signed-off-by: Wang Nan Acked-by: Alexei Starovoitov Cc: Brendan Gregg Cc: Daniel Borkmann Cc: David Ahern Cc: He Kuang Cc: Jiri Olsa Cc: Kaixu Xia Cc: Masami Hiramatsu Cc: Namhyung Kim Cc: Peter Zijlstra Cc: Zefan Li Cc: pi3orama@163.com Link: http://lkml.kernel.org/r/1437477214-149684-1-git-send-email-wangnan0@huawei.com Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Add --buildid-dir option to set cache directory

perf tools: Fix line number in the config file error message

2014-09-26T15:45:23+00:00

If we fail to parse the config file within the callback function, the line number counter 'could be' already on the next line. This results in wrong line number report like: $ cat ~/.perfconfig [call-graph] sort-key = krava $ perf record ls Fatal: bad config file line 3 in /home/jolsa/.perfconfig Fixing this by saving the current line number for this case.
