Pull perf updates from Ingo Molnar: "The main kernel side changes in this cycle were:
- Various Intel-PT updates and optimizations (Alexander Shishkin)
- Prohibit kprobes on Xen/KVM emulate prefixes (Masami Hiramatsu)
- Add support for LSM and SELinux checks to control access to the perf syscall (Joel Fernandes)
- Misc other changes, optimizations, fixes and cleanups - see the shortlog for details.
There were numerous tooling changes as well - 254 non-merge commits. Here are the main changes - too many to list in detail:
- Enhancements to core tooling infrastructure, perf.data, libperf, libtraceevent, event parsing, vendor events, Intel PT, callchains, BPF support and instruction decoding.
- There were updates to the following tools:
perf annotate perf diff perf inject perf kvm perf list perf maps perf parse perf probe perf record perf report perf script perf stat perf test perf trace

Merge tag 'perf-core-for-mingo-5.5-20191011' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core
Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:
perf trace:
Arnaldo Carvalho de Melo:
- Reuse the strace-like syscall_arg_fmt->scnprintf() beautification routines (convert integer arguments into strings, like open flags, etc) in tracepoint arguments.
For now the type based scnprintf routines (pid_t, umode_t, etc) and the ones based in well known arg name based ("fd", etc) gets associated with tracepoint args of that type.
A tracepoint only arg, "msr", for the msr:{write,read}_msr gets added as an initial step.
- Introduce syscall_arg_fmt->strtoul() methods to be the reverse operation of ->scnprintf(), i.e. to go from a string to an integer.
- Implement --filter, just like in 'perf record', that affects the tracepoint events specied thus far in the command line, use the ->strtoul() methods to allow strings in tables associated with beautifiers to the integers the in-kernel tracepoint (eBPF later) filters expect, e.g.:
# perf trace --max-events 1 -e sched:*ipi --filter="cpu==1 || cpu==2" 0.000 as/24630 sched:sched_wake_idle_without_ipi(cpu: 1) #

- Default to not using libtraceevent and its plugins for beautifying tracepoint arguments, since now we're reusing the strace-like beatufiers. Use --libtraceevent_print (using just --libtrace is unambiguous and can be used as a short hand) to go back to those beautifiers.
This will help in the transition, as can be seen in some of the sched tracepoints that still need some work in the libbeauty based mode:

perf trace: Allow choosing how to augment the tracepoint arguments
So far we used the libtraceevent printing routines when showing tracepoint arguments, but since 'perf trace' has a lot of beautifiers for syscall arguments, and since some of those can be used to augment tracepoint arguments, add a routine to make use of those beautifiers and allow the user to choose which one to use.
The default now is to use the same beautifiers used for the strace-like sys_enter+sys_exit lines, but the user can choose the libtraceevent ones by either using the:
perf trace --libtraceevent_print
command line option, or by setting:
# cat ~/.perfconfig [trace] tracepoint_beautifiers = libtraceevent
For instance, here are some examples:
# perf trace -e sched:*switch,*sleep,sched:*wakeup,exit*,sched:*exit sleep 1 0.000 sched:sched_wakeup(comm: "perf", pid: 5273 (perf), prio: 120, success: 1, target_cpu: 6) 0.621 nanosleep(rqtp: 0x7ffdd06d1140, rmtp: NULL) ... 0.628 sched:sched_switch(prev_comm: "sleep", prev_pid: 5273 (sleep), prev_prio: 120, prev_state: 1, next_comm: "swapper/6", next_pid: 0, next_prio: 120) 1000.879 sched:sched_wakeup(comm: "sleep", pid: 5273 (sleep), prio: 120, success: 1, target_cpu: 6) 0.621 ... [continued]: nanosleep()) = 0 1001.026 exit_group(error_code: 0) = ? 1001.216 sched:sched_process_exit(comm: "sleep", pid: 5273 (sleep), prio: 120) #
And then using libtraceevent, as before:
# perf trace --libtraceevent_print -e sched:*switch,*sleep,sched:*wakeup,exit*,sched:*exit sleep 1 0.000 sched:sched_wakeup(comm=perf pid=5288 prio=120 target_cpu=001) 0.739 nanosleep(rqtp: 0x7ffeba6c2f40, rmtp: NULL) ... 0.747 sched:sched_switch(prev_comm=sleep prev_pid=5288 prev_prio=120 prev_state=S ==> next_comm=swapper/1 next_pid=0 next_prio=120) 1000.902 sched:sched_wakeup(comm=sleep pid=5288 prio=120 target_cpu=001) 0.739 ... [continued]: nanosleep()) = 0 1001.012 exit_group(error_code: 0) = ? #
The new default allocates an array of 'struct syscall_arg_fmt' for the tracepoint arguments and, just like with syscall arguments, tries to find suitable syscall_arg__scnprintf_NAME() routines to augment those tracepoint arguments based on their type (as in the tracefs "format" file), or even in their name + type, for instance arguntents with names ending in "fd" with type "int" get the fd scnprintf beautifier attached, etc.
Soon this will take advantage of the kernel BTF information to augment enumerations based on the tracefs "format" type info.

Arnaldo Carvalho de Melo:
- Set display thread COMM to help with debugging.
- Collapse and resort evsels in a group, so that we have output similar to 'perf report' when using event groups, i.e.
perf top -e '{cycles,instructions}'
Will have two columns, and the instructions one will work.
core:
Igor Lubashev:
- Detect if libcap development files are available so that we can use capabilities to match the checks made by the kernel instead of using plain (geteuid() == 0).
Intel:
Haiyan Song:
- Add Icelake V1.00 event file.
perf trace:
Leo Yan:
- Fix segmentation fault when access syscall info on arm64.

perf config: Document the PERF_CONFIG environment variable
There was a provision for setting this variable, but not the getenv("PERF_CONFIG") call to set it, as this was fixed in the previous cset, document that it can be used to ask for using an alternative .perfconfig file or to disable reading whatever file exists in the system or home directory, i.e. using:
export PERF_CONFIG=/dev/null
