Subject: [PATCH v5 20/23] PCI: hotplug: movable BARs: Enable the feature by default
Date: Fri, 16 Aug 2019 19:50:58 +0300 [thread overview]
Message-ID: <20190816165101.911-21-s.miroshnichenko@yadro.com> (raw)
In-Reply-To: <20190816165101.911-1-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 by default now. Tested on:
- x86_64 with "pci=realloc,assign-busses,use_crs,pcie_bus_peer2peer"
command line argument;
- POWER8 PowerNV+PHB3 ppc64le with "pci=realloc,pcie_bus_peer2peer".
In case of problems it is still can be overridden by the following command
line option:
pcie_movable_bars=off
