Now it is possible to use these strings when setting up filters for the msr:*
tracepoints, like:

  # perf trace -e msr:* --filter=msr==IA32_TSX_CTRL
  ^C[root@quaco ~]#

If we use an invalid operator we can check what is the filter that is put in
place:

  # perf trace -e msr:* --filter=msr=IA32_TSX_CTRL
  Failed to set filter "(msr=0x122) && (common_pid != 25976 && common_pid != 25860)" on event msr:read_msr with 22 (Invalid argument)

One can as well use -v to see the tracepoints and its filters:

  # perf trace -v -e msr:* --filter=msr==IA32_TSX_CTRL
  Using CPUID GenuineIntel-6-8E-A
  New filter for msr:read_msr: (msr==0x122) && (common_pid != 26110 && common_pid != 25860)
  New filter for msr:write_msr: (msr==0x122) && (common_pid != 26110 && common_pid != 25860)
  New filter for msr:rdpmc: (msr==0x122) && (common_pid != 26110 && common_pid != 25860)
  mmap size 528384B
  ^C#

Better than keep looking up those numbers, works with callchains as
well, e.g. for something more common:

  # perf trace -e msr:*/max-stack=16/ --filter="msr==IA32_SPEC_CTRL" --max-events=2
