Subject: Re: [PATCH v14 13/13] virt/steal_governor: Enable the driver
Date: Mon, 28 Sep 2026 05:48:23 +0000 [thread overview]
Message-ID: <20260928054824.300791F000FF@smtp.kernel.org> (raw)
In-Reply-To: <20260928053728.797539-14-sshegde@linux.ibm.com>
> Provide a config option to enable the steal_governor driver.
> Since the feature targets paravirtualized environments and requires SMP,
> enforce those dependencies. The driver selects CONFIG_PREFERRED_CPU
> for the core scheduler mechanisms to work.
>
> It is recommended to build the driver as a module (m) instead of
> built-in (y) due to the following reasons:
>
> - Module parameters are read-only after initialization. Building as a
> module allows updating these parameters by simply reloading the module.
> Default module parameters cannot work in all configurations.
>
> - The driver can be completely disabled by unloading the module.
>
> - This feature works best when all VMs operate in a cooperative manner.
> Requiring an explicit module load ensures intentional deployment
> across all VMs by the system administrator.
