Subject: [PATCH v9 22/26] PCI: hotplug: Enable the movable BARs feature by default
Date: Fri, 18 Dec 2020 20:40:07 +0300
Message-ID: <20201218174011.340514-23-s.miroshnichenko@yadro.com> (raw)
In-Reply-To: <20201218174011.340514-1-s.miroshnichenko@yadro.com>

This is the last patch in the series which implements the essentials of the
movable BARs feature, so it is turned on by default now.

Tested on x86_64; and with extra patches applied, it also works on ppc64le
(PowerNV).

In case of problems it is still can be overridden by the following command
line option:

  pcie_movable_bars=off
