Subject: [PATCH] x86/hyper-v: add "polling" bit to hv_synic_sint
Date: Sun, 22 Dec 2019 23:34:04 +0000 [thread overview]
Message-ID: <20191222233404.1629-1-wei.liu@kernel.org> (raw)
That bit is documented in TLFS 5.0c as follows:
Setting the polling bit will have the effect of unmasking an
interrupt source, except that an actual interrupt is not generated.
