Subject[PATCH v2 0/4] cpuidle, haltpoll: governor switching on idle register
Date
Hey,

Presented herewith a series with aims to tie in together the haltpoll
idle driver and governor, without sacrificing previous governor setups.
In addition, there are a few fixes with respect to module loading for
cpuidle-haltpoll.

The series is organized as follows:

Patch 1: Allows idle driver stating a preferred governor that it
wants to use, based on discussion here:

https://lore.kernel.org/kvm/457e8ca1-beb3-ca39-b257-e7bc6bb35d4d@oracle.com/

Patch 2: Decrease rating of governor, and allows previous defaults
to be as before haltpoll, while using @governor to switch to haltpoll
when haltpoll driver is registered;

Patch 3 - 4: Module loading fixes. first is the incorrect error
reporting and second is supportting module unloading.

Thoughts, comments appreciated.

Thanks,
Joao

v2:
* Add missing Fixes tag on patches 3 and 4.

Joao Martins (4):
cpuidle: allow governor switch on cpuidle_register_driver()
cpuidle-haltpoll: set haltpoll as preferred governor
cpuidle-haltpoll: return -ENODEV on modinit failure
cpuidle-haltpoll: do not set an owner to allow modunload
