Subject: Re: [PATCH v2 1/2] s390/appldata: Emulate virtual timer with delayed work
Date: Tue, 06 Oct 2026 14:08:10 +0000 [thread overview]
Message-ID: <20261006140811.69EA91F000FF@smtp.kernel.org> (raw)
In-Reply-To: <20261006140113.3128582-2-hca@linux.ibm.com>
> Emulate the virtual timer in appldata using delayed work: the work is

> configured CPU-time interval elapses (remaining CPU time / number of
> online CPUs), with a minimum delay of 100ms. The work then reads
> per-CPU statistics of all online CPUs to check whether enough CPU time
