Allow user to easily switch all events to user or kernel space with simple
--all-user or --all-kernel options.
This will be handy within perf mem/c2c wrappers to switch easily monitoring
modes.
Committer note:
Testing it:
# perf record --all-kernel --all-user -a sleep 2
Error: option `all-user' cannot be used with all-kernel
Usage: perf record [<options>] [<command>]
or: perf record [<options>] -- <command> [<options>]
--all-user Configure all used events to run in user space.
--all-kernel Configure all used events to run in kernel space.
# perf record --all-user --all-kernel -a sleep 2
Error: option `all-kernel' cannot be used with all-user
Usage: perf record [<options>] [<command>]
or: perf record [<options>] -- <command> [<options>]
--all-kernel Configure all used events to run in kernel space.
--all-user Configure all used events to run in user space.
# perf record --all-user -a sleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 1.416 MB perf.data (162 samples) ]
# perf report | grep '\[k\]'
# perf record --all-kernel -a sleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 1.423 MB perf.data (296 samples) ]
# perf report | grep '\[\.\]'
