Subject: [PATCH 3/9] cpuidle-haltpoll: condition on ARCH_CPUIDLE_HALTPOLL
Date: Tue, 30 Apr 2024 11:37:24 -0700 [thread overview]
Message-ID: <20240430183730.561960-4-ankur.a.arora@oracle.com> (raw)
In-Reply-To: <20240430183730.561960-1-ankur.a.arora@oracle.com>
The cpuidle-haltpoll driver and its namesake governor are selected
under KVM_GUEST on X86. In addition, KVM_GUEST also selects
ARCH_CPUIDLE_HALTPOLL and defines the requisite
arch_haltpoll_{enable,disable}() functions.
So remove the explicit dependence on KVM_GUEST, and instead use
ARCH_CPUIDLE_HALTPOLL as proxy for architectural support for
haltpoll.
While at it, change "halt poll" to "haltpoll" in one of the summary
clauses, since the second form is used everywhere else.
