perf mem: Add PERF_MEM_LVLNUM_NA to PERF_MEM_DATA_SRC_NONE

2023-04-10T22:26:08+00:00

Add PERF_MEM_LVLNUM_NA wherever PERF_MEM_DATA_SRC_NONE is used to set default values.

perf thread: Move thread__resolve() from event.h

2022-10-31T14:07:03+00:00

Its a thread method, so move it to thread.h, this way some places that were using event.h just to get this prototype may stop doing so and speed up building and disentanble the header dependency graph. Signed-off-by: Arnaldo Carvalho de Melo

perf symbol: Move addr_location__put() from event.h

2022-10-31T14:06:56+00:00

Its a addr_location method, so move it to symbol.h, where 'struct addr_location' is, this way some places that were using event.h just to get this prototype may stop doing so and speed up building and disentanble the header dependency graph. Signed-off-by: Arnaldo Carvalho de Melo

perf machine: Move machine__resolve() from event.h

2022-10-31T14:06:52+00:00

Its a machine method, so move it to machine.h, this way some places that were using event.h just to get this prototype may stop doing so and speed up building and disentanble the header dependency graph. Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Move 'struct perf_sample' to a separate header file to disentangle headers

2022-10-31T14:06:41+00:00

Some places were including event.h just to get 'struct perf_sample', move it to a separate place so that we speed up a bit the build. Signed-off-by: Arnaldo Carvalho de Melo

perf event: Drop perf_regs.h include, not needed anymore

2022-10-27T19:37:26+00:00

Since commit c897899752478d4c ("perf tools: Prevent out-of-bounds access to registers") the util/event.h header doesn't use anything from util/perf_regs.h, so drop it to untangle the header dependency tree a bit, speeding up compilation. Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Support reading PERF_FORMAT_LOST

2022-08-19T18:56:56+00:00

The recent kernel added lost count can be read from either read(2) or ring buffer data with PERF_SAMPLE_READ. As it's a variable length data we need to access it according to the format info. But for perf tools use cases, PERF_FORMAT_ID is always set. So we can only check PERF_FORMAT_LOST bit to determine the data format. Add sample_read_value_size() and next_sample_read_value() helpers to make it a bit easier to access. Use them in all places where it reads the struct sample_read_value.

perf cpumap: Synthetic events and const/static

2022-08-19T15:26:58+00:00

Make the cpumap arguments const to make it clearer they are in rather than out arguments. Make two functions static and remove external declarations.

perf tools: Add perf_event__is_guest()

2022-07-20T14:08:42+00:00

Add a helper function to determine if an event is a guest event. Signed-off-by: Adrian Hunter Cc: Andi Kleen Cc: Ian Rogers Cc: Jiri Olsa Cc: Namhyung Kim Cc: kvm@vger.kernel.org Link: https://lore.kernel.org/r/20220711093218.10967-28-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Add machine_pid and vcpu to perf_sample

2022-07-20T14:08:04+00:00

When parsing a sample with a sample ID, copy machine_pid and vcpu from perf_sample_id to perf_sample. Note, machine_pid will be zero when unused, so only a non-zero value represents a guest machine. vcpu should be ignored if machine_pid is zero. Note also, machine_pid is used with events that have come from injecting a guest perf.data file, however guest events recorded on the host (i.e. using perf kvm) have the (QEMU) hypervisor process pid to identify them - refer machines__find_for_cpumode().
