Subject: Re: [PATCH 2/5] sched/vtime: get rid of generic vtime_task_switch() implementation

Le Sun, Jan 28, 2024 at 08:58:51PM +0100, Alexander Gordeev a écrit :
> The generic vtime_task_switch() implementation gets built only
> if __ARCH_HAS_VTIME_TASK_SWITCH is not defined, but requires an
> architecture to implement arch_vtime_task_switch() callback at
> the same time, which is confusing.
>
> Further, arch_vtime_task_switch() is implemented for 32-bit PowerPC
> architecture only and vtime_task_switch() generic variant is rather
> superfluous.
>
> Simplify the whole vtime_task_switch() wiring by moving the existing
> generic implementation to PowerPC.
