Subject: Re: [RFC PATCH] PCI, kdump: Clear bus master bit upon shutdown in kdump kernel
Date: Fri, 28 Feb 2020 11:53:19 -0800 [thread overview]
Message-ID: <CABeXuvqm1iUGt1GWC9eujuoaACdPiZ2X=3LjKJ5JXKZcXD_z_g@mail.gmail.com> (raw)
In-Reply-To: <CACPcB9dv1YPhRmyWvtdt2U4g=XXU7dK4bV4HB1dvCVMTpPFdzA@mail.gmail.com>
I think the quirk clearing BME might not solve all the problems, since
endpoint devices can sometimes not honor BME settings.
Better solution to me seems like not letting devices that we cannot
identify send us interrupts. I was working on a patch for this. I'm on
vacation for a couple of weeks and can post an update after I test out
my patch internally.
