[kvm-unit-tests PATCH v9 0/3] ARM PMU tests

From: Wei Huang
Date: Fri Nov 18 2016 - 23:16:01 EST

Changes from v8:
* Probe PMU version based on ID_DFR0
* pmccntr_read() now returns 64bit and can handle both 32bit and 64bit
PMCCNTR based on PMU version.
* Add pmccntr_write() support
* Use a common printf format PRId64 to support 64bit variable smoothly in
test functions
* Add barriers to several PMU write functions
* Verfied on different execution modes

1) Current KVM code has bugs in handling PMCCFILTR write. A fix (see
below) is required for this unit testing code to work correctly under
KVM mode.


Wei Huang (3):
arm: Add PMU test
arm: pmu: Check cycle count increases
arm: pmu: Add CPI checking
