TAPSET::MEMORY(3stap) TAPSET::MEMORY(3stap)
tapset::memory - systemtap memory tapset
This family of probe points is used to probe memory-related
events.
vm_fault_contains
Test return value for page fault reason
See function::vm_fault_contains(3stap)
for details.
vm.pagefault
Records that a page fault occurred
See probe::vm.pagefault(3stap)
for details.
vm.pagefault.return
Indicates what type of fault occurred
See probe::vm.pagefault.return(3stap)
for details.
addr_to_node
Returns which node a given address belongs to within a NUMA
system
See function::addr_to_node(3stap)
for details.
vm.write_shared
Attempts at writing to a shared page
See probe::vm.write_shared(3stap)
