Andreas Kling 266d7ca268 ProfileViewer: Add basic support for loading "perfcore" files
"perfcore" is the file that the kernel generates after a process that
was recording performance events has exited.

This patch teaches ProfileViewer how to load (and symbolicate!) those
files so that we can look at them. This will need a bunch more work
to make it truly useful.

SerenityOS

Graphical Unix-like operating system for x86 computers.

Travis CI status

About

SerenityOS is a love letter to '90s user interfaces with a custom Unix-like core. It flatters with sincerity by stealing beautiful ideas from various other systems.

Roughly speaking, the goal is a marriage between the aesthetic of late-1990s productivity software and the power-user accessibility of late-2000s *nix. This is a system by me, for me, based on the things I like.

If you like some of the same things, you are welcome to join the project. It would be great to one day change the above to say "this is a system by us, for us, based on the things we like." :^)

I regularly post raw hacking sessions and demos on my YouTube channel.

Sometimes I write about the system on my github.io blog.

I'm also on Patreon and GitHub Sponsors if you would like to show some support that way.
