Subject: [Qemu-devel] [PATCH 3/7] update halted state on mp_state sync
Date: Thu, 26 Nov 2009 15:24:56 -0200 [thread overview]
Message-ID: <1259256300-23937-4-git-send-email-glommer@redhat.com> (raw)
In-Reply-To: <1259256300-23937-3-git-send-email-glommer@redhat.com>
If we are using in-kernel irqchip, halted state belongs in the kernel.
So everytime we grab kernel's idea of mpstate, we also need to propagate
halted state to userspace.
