This is consistently failing for me on a P8 Tuleta (pvr 004b 0201):
# ./ptrace-ebb
test: ptrace_ebb_pmu

EBBRR: 100059f8
EBBHR: 100053cc; expected: 100053cc
BESCR: 8000000100000000
SIAR: 100012d0
SDAR: 3fff7e4cc000
SIER: 3000000; expected: 2000000
MMCR2: 0; expected: 0
MMCR0: 180000080; expected: 180000080
failure: ptrace_ebb_pmu
cheers

Michael,
Yes.. SIER has different value in baremetal and virtual machine
due to different MSR[HV] value. I will correct it. Originally I only
tested in virtual BE/LE machines.
Currently all tests cases (with fix) passed on one baremetal P8 machine
with LE OS installed. And I will try to find another baremetal with BE
OS installed to test.
Thanks for indicating it.
BR,
Simon
