Subject: Suggestion: „spectre_v2=off“ and „nopti“ per default in "Intel Atom N270" case?
Date: Sat, 19 May 2018 21:53:02 +0200 [thread overview]
Message-ID: <72a7122d-0020-f307-a76d-bb80a2c19842@web.de> (raw)
Hi,
Since the old "in-order-execution" Intel CPUs like the Intel Atom N270
(known for being installed in many Netbooks and Nettops) are not
sensitive for "Meltdown" & "Spectre" , wouldn't it be a good idea to
exclude these anyway "weak" CPUs from the costly patches by default?
Browsing the web, I can "feel the difference" if the matching kernel
options are applied on such a device.
BR
