We're also writing a user-space app that can manage reservations
from user-space. It's integrated with util-linux. I'll setup a repo
shortly to share the source code, but here are some examples:

Create a global 2MB reservation:

# cacheset --create 2M

Create a 2MB reservation on CPUs 0 and 1:

# cacheset --create 2M --cpu-list 0,1
# cacheset --create 2M 0x3

Attach pid 4901 to reservation ID 1

# cacheset --attach 4901 1

Detach pid 4901 to reservation ID 1

# cacheset --detach 4901 1

Delete reservation ID 1

# cacheset --delete 1
