Error running perf c2c on Ubuntu 24.04: "Bad event or PMU" on fresh installation

I'm trying to run perf c2c on a fresh installation of Ubuntu 24.04, but it's not working as expected.

The command I'm using is:

$ perf c2c record ls

or just

$ perf c2c record

However, I'm getting the following error:

event syntax error: '..em-loads,ldlat=30/P'                                  \___ Bad event or PMUUnable to find PMU or event on a PMU of 'cpu_atom'Initial error:event syntax error: '..em-loads,ldlat=30/P'                                  \___ unknown term 'ldlat' for pmu 'cpu_atom'valid terms: event,pc,edge,inv,umask,cmask,config,config1,config2,config3,name,period,freq,branch_type,time,call-graph,stack-size,no-inherit,inherit,max-stack,nr,no-overwrite,overwrite,driver-config,percore,aux-output,aux-sample-size,metric-id,raw,legacy-cache,hardwareRun 'perf list' for a list of valid events Usage: perf record [<options>] [<command>]    or: perf record [<options>] -- <command> [<options>]    -e, --event <event>   event selector. use 'perf list' to list available events

When I check the available events using perf c2c record -e list, I see the following:

$ perf c2c record -e listldlat-loads  : availableldlat-stores : available

Here are some details about my setup:

It seems that the ldlat option is taken from here

https://github.com/torvalds/linux/blob/v6.8/tools/perf/builtin-c2c.c#L3254

Just to clarify, I am running it on a bare metal machine, not in a virtualized environment or container.

Additionally I have tried to run it with -e

$ perf c2c record -e ldlat-loadsevent syntax error: '..em-loads,ldlat=30/P'                                  \___ Bad event or PMUUnable to find PMU or event on a PMU of 'cpu_atom'Initial error:event syntax error: '..em-loads,ldlat=30/P'                                  \___ unknown term 'ldlat' for pmu 'cpu_atom'valid terms: event,pc,edge,inv,umask,cmask,config,config1,config2,config3,name,period,freq,branch_type,time,call-graph,stack-size,no-inherit,inherit,max-stack,nr,no-overwrite,overwrite,driver-config,percore,aux-output,aux-sample-size,metric-id,raw,legacy-cache,hardwareRun 'perf list' for a list of valid events Usage: perf record [<options>] [<command>]    or: perf record [<options>] -- <command> [<options>]    -e, --event <event>   event selector. use 'perf list' to list available events

$ perf c2c record -e ldlat-storesError:The cpu_atom/mem-stores/P event is not supported.

perf record works fine, but perf c2c record throws the above error.

I would really like to use c2c. Does anyone have any ideas on how to fix this?

Thanks in advance!
