Subject: [PULL 05/18] migration: Stop CPU throttling conditionally
Date: Wed, 30 Oct 2024 11:57:21 -0400	[thread overview]
Message-ID: <20241030155734.2141398-6-peterx@redhat.com> (raw)
In-Reply-To: <20241030155734.2141398-1-peterx@redhat.com>

From: Hyman Huang <yong.huang@smartx.com>

Since CPU throttling only occurs when auto-converge
is on, stop it conditionally.
