Subject: [Xen-devel] [PATCH v2 28/48] xen/sched: move struct task_slice into struct sched_unit
Date: Fri, 9 Aug 2019 16:58:13 +0200 [thread overview]
Message-ID: <20190809145833.1020-29-jgross@suse.com> (raw)
In-Reply-To: <20190809145833.1020-1-jgross@suse.com>
In order to prepare for multiple vcpus per schedule unit move struct
task_slice in schedule() from the local stack into struct sched_unit
of the currently running unit. To make access easier for the single
schedulers add the pointer of the currently running unit as a parameter
of do_schedule().
While at it switch the tasklet_work_scheduled parameter of
do_schedule() from bool_t to bool.
As struct task_slice is only ever modified with the local schedule
lock held it is safe to directly set the different units in struct
sched_unit instead of using an on-stack copy for returning the data.
