Subject: [PATCH] arch/x86/Kconfig: specify idle=poll instead of no-hlt
Date: Wed, 13 Jul 2022 18:08:40 +0200 [thread overview]
Message-ID: <20220713160840.1577569-1-steve@sk2.org> (raw)
Commit 27be45700021 ("x86 idle: remove 32-bit-only "no-hlt" parameter,
hlt_works_ok flag") removed no-hlt, but CONFIG_APM still refers to
it. Suggest "idle=poll" instead, based on the commit message:
> If a user wants to avoid HLT, then "idle=poll"
> is much more useful, as it avoids invocation of HLT
> in idle, while "no-hlt" failed to do so.
