comment How can I make perf script -g python work?
I want to count how many inter-library calls there are in average call stacks. Perf -g gives me good call stack snapshot samples, so I can run representative programs and get perf.data. However, the report tools all seem to summarise, although they do have library and function columns, and I want the raw call stacks. I was hoping perf script would let me see them annotated, as looking at the raw dump doesn't do symbol resolution for me nor tell me which lib each call is in.

Yes yes yes. When I use the standard perf reports I get symbol information; when I look at the raw dump the symbols aren't resolved.

Yes, unfortunately the call sacks in the raw output aren't annotated with function and library names. I've been trying to work it out by also looking at the MMAP events etc. Just not easy.

I was just googling for an answer myself and came across this question. I'd like to extract each and every captured callstack.

comment Improve performance etc for full-disk-encrypted drives
@Jobin I can't find any virtualisation option on the bios setup screens; but I do have AMD-V checked in the VirtualBox settings.

@Jobin you mean in the host or in the VM or in VirtualBox?

comment downgrade ppa packages to versions available at a previous point in time
the user can use dpkg directly; the user may use gdebi or some other tool instead too. I had to pick a file to parse, so I picked the one proper file - dpkg.log. It happens I use apt exclusively, but same difference.

dpkg.log is the same info but also including other apps than apt.

As I said, the normal drivers don't work for me. I need xorg-edgers. I just want to sidestep the very latest version of my drivers.
