Borislav,

This is an attempt, suggested by PeterZ for us to try to
automate those updates, so what I was expecting wasn't a report that
something changed, as I notice it myself, but an attempt at checking if
the changes in these updates would entail changes in the tools build.

Say, is there a script in tools/perf/trace/beauty/ that ends up
producing a different .c that then gets compiled/linked with tooling? Or
this is just a trivial change like happens from time to time, a typo
fix, some comments added, etc.

Some examples of what those scripts do:

⬢[acme@toolbox perf]$ tools/perf/trace/beauty/fadvise.sh
static const char *fadvise_advices[] = {
[0] = "NORMAL",
[1] = "RANDOM",
[2] = "SEQUENTIAL",
[3] = "WILLNEED",
[4] = "DONTNEED",
[5] = "NOREUSE",
};
⬢[acme@toolbox perf]$ tools/perf/trace/beauty/socket.sh
static const char *socket_families[] = {
[0] = "UNSPEC",
[1] = "LOCAL",
[2] = "INET",
[3] = "AX25",
[4] = "IPX",
[5] = "APPLETALK",
[6] = "NETROM",
[7] = "BRIDGE",
[8] = "ATMPVC",
[9] = "X25",
[10] = "INET6",
[11] = "ROSE",
[12] = "DECnet",
[13] = "NETBEUI",
[14] = "SECURITY",
[15] = "KEY",
[16] = "NETLINK",
[17] = "PACKET",
[18] = "ASH",
[19] = "ECONET",
[20] = "ATMSVC",
[21] = "RDS",
[22] = "SNA",
[23] = "IRDA",
[24] = "PPPOX",
[25] = "WANPIPE",
[26] = "LLC",
[27] = "IB",
[28] = "MPLS",
[29] = "CAN",
[30] = "TIPC",
[31] = "BLUETOOTH",
[32] = "IUCV",
[33] = "RXRPC",
[34] = "ISDN",
[35] = "PHONET",
[36] = "IEEE802154",
[37] = "CAIF",
[38] = "ALG",
[39] = "NFC",
[40] = "VSOCK",
[41] = "KCM",
[42] = "QIPCRTR",
[43] = "SMC",
[44] = "XDP",
};
⬢[acme@toolbox perf]$

Some of those files are used for building the tools, so that a
tarball generated from:

⬢[acme@toolbox perf]$ make help | grep perf
perf-tar-src-pkg - Build perf-5.13.0-rc4.tar source tarball
perf-targz-src-pkg - Build perf-5.13.0-rc4.tar.gz source tarball
perf-tarbz2-src-pkg - Build perf-5.13.0-rc4.tar.bz2 source tarball
perf-tarxz-src-pkg - Build perf-5.13.0-rc4.tar.xz source tarball
⬢[acme@toolbox perf]$

will build in older systems where things added to the updated copy of
the kernel headers isn't present, so trying to update the file and then
rebuild perf, only warning me if it doesn't build would give me an early
warning about things that are breaking and that I should look sooner
rather than later.

Doing just the diff is not that useful :-)

One more output that is x86 specific and allows this to work:

Or look at the first 3 write_msr events for that IA32_TSC_DEADLINE to learn why
it happens so often:
