Enumeration Type Documentation

anonymous enum

Enumerator:

OPERF_SAMPLES	nr. samples
OPERF_KERNEL	nr. kernel samples
OPERF_PROCESS	nr. userspace samples
OPERF_INVALID_CTX	nr. samples lost due to sample address not in expected range for domain
OPERF_LOST_KERNEL	nr. kernel samples lost
OPERF_LOST_SAMPLEFILE	nr samples for which sample file can't be opened
OPERF_LOST_NO_MAPPING	nr samples lost due to no mapping
OPERF_NO_APP_KERNEL_SAMPLE	nr. user ctx kernel samples dropped due to no app context available
OPERF_NO_APP_USER_SAMPLE	nr. user samples dropped due to no app context available
OPERF_BT_LOST_NO_MAPPING	nr. backtrace samples dropped due to no mapping
OPERF_LOST_INVALID_HYPERV_ADDR	nr. hypervisor samples dropped due to address out-of-range
OPERF_RECORD_LOST_SAMPLE	nr. samples lost reported by perf_events kernel
OPERF_MAX_STATS	end of stats
