Before:
# perf list _alloc_ | head -10
#
After:
# perf list _alloc_ | head -10
ext4:ext4_alloc_da_blocks [Tracepoint event]
ext4:ext4_get_implied_cluster_alloc_exit [Tracepoint event]
kmem:kmem_cache_alloc_node [Tracepoint event]
kmem:mm_page_alloc_extfrag [Tracepoint event]
kmem:mm_page_alloc_zone_locked [Tracepoint event]
xen:xen_mmu_alloc_ptpage [Tracepoint event]
#
And it works for all types of events:
# perf list br
List of pre-defined events (to be used in -e):
branch-instructions OR branches [Hardware event]
branch-misses [Hardware event]
branch-load-misses [Hardware cache event]
branch-loads [Hardware cache event]
branch-instructions OR cpu/branch-instructions/ [Kernel PMU event]
branch-misses OR cpu/branch-misses/ [Kernel PMU event]
filelock:break_lease_block [Tracepoint event]
filelock:break_lease_noblock [Tracepoint event]
filelock:break_lease_unblock [Tracepoint event]
syscalls:sys_enter_brk [Tracepoint event]
syscalls:sys_exit_brk [Tracepoint event]
