Detailed Description
Benefit to Fedora
- Improves power management by not waking up 100 (or 1000, or whatever) times a second.
Scope
- Kernel changes
Test Plan
- Examine built kernel config, make sure CONFIG_NO_HZ is set.
- Boot kernel ; use powertop or similar software to determine that it is running in a tickless manner.
User Experience
- Should not affect user's experience in a noticeable way, aside from increasing battery life.
Dependencies
- Depends on upstream kernel work.
Contingency Plan
- Back out the tickless patch, or build without CONFIG_NO_HZ
