But for other configurations it is worse:
config NO_HZ_FULL
bool "Full dynticks system (tickless)"
...
This is implemented at the expense of some overhead in user <-> kernel
transitions: syscalls, exceptions and interrupts. Even when it's
dynamically off.
Package: src:linux
Followup-For: Bug #804857
Hi, I am just curious, and wanted to know if there is some progress on
enableing NO_HZ_FULL in generic debian on most architectures?
I wouldn't also mind separate kernel image with CONFIG_PREEMPT (full
prempetion) and HZ=1000 for desktop / soft real
Dear Maintainer,
Is it possible to enable this option for the real-time kernel image, like
suggested one year ago ?
It is a feature that is required for many real-time applications when a CPU is
only dedicated to a process.
Thank you,
Mikael

Dear Maintainer,
Could you please enable kernel options CONFIG_NO_HZ_FULL, CONFIG_RCU_NOCB_CPU
and CONFIG_RCU_NOCB_CPU_NONE.
As explained in: https://www.kernel.org/doc/Documentation/timers/NO_HZ.txt
This options:
- Don't modify default kernel behavior
