Subject: [PATCH 1/4] s390x/pci: use a reserved ID for the default PCI group
Date: Thu, 2 Dec 2021 11:41:07 -0500 [thread overview]
Message-ID: <20211202164110.326947-2-mjrosato@linux.ibm.com> (raw)
In-Reply-To: <20211202164110.326947-1-mjrosato@linux.ibm.com>
The current default PCI group being used can technically collide with a
real group ID passed from a hostdev. Let's instead use a group ID that comes
from a special pool that is architected to be reserved for simulated devices.
Fixes: 28dc86a072 ("s390x/pci: use a PCI Group structure")
