"message": "perf trace: live-mode command-line cleanup\n\nThis patch attempts to make the perf trace command-line for live-mode\ncommands more user-friendly and consistent with other perf commands.\n\nThe main change it makes is to allow \u003ccommands\u003e to be run as part of\nperf trace live-mode commands, as other perf commands do, instead of\nthe system-wide traces they\u0027re currently hard-coded to by the shell\nscripts.\n\nWith this patch, the following live-mode trace now works as expected:\n\n $ perf trace rw-by-pid ls -al\n\nThe previous system-wide behavior for this command would still be\navailable by explicitly specifying -a:\n\n $ perf trace rw-by-pid -a ls -al\n\nand if no \u003ccommand\u003e is specified, the output is also system-wide:\n\n $ perf trace rw-by-pid\n\nBecause live-mode requires both record and report steps to be invoked,\nit isn\u0027t always possible to know which args to send to the report and\nwhich to send to the record steps - mainly this is the case for report\nscripts with optional args - in those cases it would be necessary to\nuse separate \u0027perf trace record\u0027 and \u0027perf trace report\u0027 steps.\n\nFor example:\n\n $ perf trace syscall-counts ls\n\nHere we can\u0027t decide whether ls should be passed as a param to the\nsyscall-counts script or whether we should invoke ls as a \u003ccommand\u003e.\nIn these cases, we just say that we\u0027ll ignore optional script params\nand always interpret the extra arguments as a \u003ccommand\u003e.\n\nIf the user instead wants the other interpretation, that can be\naccomplished by using separate record and report commands explicitly:\n\n $ perf trace record syscall-counts\n $ perf trace report syscall-counts ls\n\nSo the rules that this patch implements, which seem to make the most\nintuitive sense for live-mode commands:\n\n- for commands with optional args and commands with no args, no args\n are sent to the report script, all are sent to the record step\n\n- for \u0027top\u0027 commands i.e. that end with \u0027top\u0027, \u003ccommands\u003e can\u0027t be\n used - all extra args are send to the report script as params\n\n- for commands with required args, the n required args are taken to be\n the first n args after the script name and sent to the report\n script, and the rest are sent to the record step\n\nSigned-off-by: Tom Zanussi \u003ctom.zanussi@linux.intel.com\u003e\nAcked-by: Arnaldo Carvalho de Melo \u003cacme@ghostprotocols.net\u003e\n" }, { "commit":
