Subject: [PATCH 0/2] efi: Disable runtime services on RT
Date: Fri, 24 Sep 2021 15:49:17 +0200	[thread overview]
Message-ID: <20210924134919.1913476-1-bigeasy@linutronix.de> (raw)

These two patches change the default of EFI's runtime service to off on
PREEMPT_RT and allow it to be overwritten in case something needs to be
done like changing the boot-order or so.
The reasoning is to avoid unforeseen large latencies, like the one
observed while using efi-rtc, by default.

Sebastian
