[PATCH i-g-t v2 0/8] tools/gputop: add i915 PMU engine monitoring

[Sebastian Brzezinka <sebastian.brzezinka@intel.com>]

This series fixes the existing (currently disabled/broken) xe PMU
backend for gputop, adds an equivalent i915 PMU backend, and wires
both into the main gputop display loop so that per-engine busyness
is shown for whichever Intel GPU driver is bound. It also adds
tools_test subtests covering engine discovery, graceful handling of
denied PMU access, and PMU sampling correctness.

v2:
  - pmu_read_multi() stays void for xe: its percentage calculation
    doesn't need the time value, unlike i915.
  - Simplified the commit message.
  - gputop_no_crash_unprivileged now uses igt_system_quiet() instead
    of igt_system_cmd()
