Inject events from a perf.data file recorded in a virtual machine into
a perf.data file recorded on the host at the same time.
Only side band events (e.g. mmap, comm, fork, exit etc) and build IDs are
injected. Additionally, the guest kcore_dir is copied as kcore_dir__
appended to the machine PID.
This is non-trivial because:
o It is not possible to process 2 sessions simultaneously so instead
events are first written to a temporary file.
o To avoid conflict, guest sample IDs are replaced with new unused sample
IDs.
o Guest event's CPU is changed to be the host CPU because it is more
useful for reporting and analysis.
o Sample ID is mapped to machine PID which is recorded with VCPU in the
id index. This is important to allow guest events to be related to the
guest machine and VCPU.
o Timestamps must be converted.
o Events are inserted to obey finished-round ordering.
The anticipated use-case is:
- start recording sideband events in a guest machine
- start recording an AUX area trace on the host which can trace also the
guest (e.g. Intel PT)
- run test case on the guest
- stop recording on the host
- stop recording on the guest
- copy the guest perf.data file to the host
- inject the guest perf.data file sideband events into the host perf.data
file using perf inject
- the resulting perf.data file can now be used
Subsequent patches provide Intel PT support for this.

perf_sample_id to perf_sample.

Note also, machine_pid is used with events that have come from injecting a

perf kvm) have the (QEMU) hypervisor process pid to identify them - refer

It is possible to know which guest machine was running at a point in time
based on the PID of the currently running host thread. That is, perf
identifies guest machines by the PID of the hypervisor.
To determine the guest CPU, put it on the hypervisor (QEMU) thread for
that VCPU.
This is done when processing the id_index which provides the necessary

When injecting events from a guest perf.data file, the events will have
separate sample ID numbers. These ID numbers can then be used to determine
which machine an event belongs to. To facilitate that, add machine_pid and
vcpu to id_index records. For backward compatibility, these are added at
the end of the record, and the length of the record is used to determine
if they are present or not.
Note, this is needed because the events from a guest perf.data file contain
the pid/tid of the process running at that time inside the VM not the
pid/tid of the (QEMU) hypervisor thread. So a way is needed to relate
guest events back to the guest machine and VCPU, and using sample ID
numbers for that is relatively simple and convenient.

point is recorded in machine->root_dir.
perf already iterates guest machines when adding files to the build ID

the build ID cache using the "proper" name i.e. relative to the guest root
directory not the host root directory.

This new option displays all of the information needed to do external
BuildID-based symbolization of kernel stack traces, such as those collected
by bpf_get_stackid().
For each kernel module plus the main kernel, it displays the BuildID,
the start and end virtual addresses of that module's text range (rounded
out to page boundaries), and the pathname of the module.
When run as a non-privileged user, the actual addresses of the modules'
text ranges are not available, so the tools displays "0, <text length>" for
kernel modules and "0, 0xffffffffffffffff" for the kernel itself.

On powerpc, 'perf trace' is crashing with a SIGSEGV when trying to
process a perf.data file created with 'perf trace record -p':
#0 0x00000001225b8988 in syscall_arg__scnprintf_augmented_string <snip> at builtin-trace.c:1492
#1 syscall_arg__scnprintf_filename <snip> at builtin-trace.c:1492
#2 syscall_arg__scnprintf_filename <snip> at builtin-trace.c:1486
#3 0x00000001225bdd9c in syscall_arg_fmt__scnprintf_val <snip> at builtin-trace.c:1973
#4 syscall__scnprintf_args <snip> at builtin-trace.c:2041
#5 0x00000001225bff04 in trace__sys_enter <snip> at builtin-trace.c:2319
That points to the below code in tools/perf/builtin-trace.c:
/*
* If this is raw_syscalls.sys_enter, then it always comes with the 6 possible
* arguments, even if the syscall being handled, say "openat", uses only 4 arguments
* this breaks syscall__augmented_args() check for augmented args, as we calculate
* syscall->args_size using each syscalls:sys_enter_NAME tracefs format file,
* so when handling, say the openat syscall, we end up getting 6 args for the
* raw_syscalls:sys_enter event, when we expected just 4, we end up mistakenly
* thinking that the extra 2 u64 args are the augmented filename, so just check
* here and avoid using augmented syscalls when the evsel is the raw_syscalls one.
*/
if (evsel != trace->syscalls.events.sys_enter)
augmented_args = syscall__augmented_args(sc, sample, &augmented_args_size, trace->raw_augmented_syscalls_args_size);
As the comment points out, we should not be trying to augment the args
for raw_syscalls. However, when processing a perf.data file, we are not
initializing those properly. Fix the same.

The test does not always correctly determine the number of events for
hybrids, nor allow for more than 1 evsel when parsing.
Fix by iterating the events actually created and getting the correct
evsel for the events processed.

"Due to a recent report [1] we need to revert the radix tree to xarray
conversion patches.
There's a problem with sleeping under spinlock, when xa_insert could
allocate memory under pressure. We use GFP_NOFS so this is a real
problem that we unfortunately did not discover during review.
I'm sorry to do such change at rc6 time but the revert is IMO the
safer option, there are patches to use mutex instead of the spin locks
but that would need more testing. The revert branch has been tested on
a few setups, all seem ok.
The conversion to xarray will be revisited in the future"
