perf test: Fix "all PMU test" to skip parametrized events

2022-12-21T17:52:40+00:00

Parametrized events are not only a powerpc domain. They occur on other
platforms too (e.g. aarch64). They should be ignored in this testcase,
since proper setup of the parameters is out of scope of this script.

Let's not filter them out by PMU name, but rather based on the fact that
they expect a parameter.

perf tools: Use "grep -E" instead of "egrep"

2022-12-14T18:28:19+00:00

The latest version of grep claims the egrep is now obsolete so the build
now contains warnings that look like:

	egrep: warning: egrep is obsolescent; using grep -E

fix this up by moving the related file to use "grep -E" instead.

  sed -i "s/egrep/grep -E/g" `grep egrep -rwl tools/perf`

Here are the steps to install the latest grep:

  wget http://ftp.gnu.org/gnu/grep/grep-3.8.tar.gz
  tar xf grep-3.8.tar.gz
  cd grep-3.8 && ./configure && make
  sudo make install
  export PATH=/usr/local/bin:$PATH

perf test: Fix record test on KVM guests

2022-11-23T13:35:45+00:00

Using precise flag with br_inst_retired.near_call causes the test fail
on KVM guests, even when the guests have PMU forwarding enabled and the
event itself is supported.

Remove the precise flag in order to make the test work on KVM guests.
