There are several EEH sysfs properties that only exists when the "ibm,is-open-sriov-pf" property appears in the device tree node of the PCI device. This used on pseries to indicate to the guest that the hypervisor allows the guest to configure the SR-IOV capability. Doing this requires some handshaking between the guest, hypervisor and userspace when a VF is EEH frozen which is why these properties exist. This is all dead code on non-pseries platforms so wrap it in an #ifdef CONFIG_PPC_PSERIES to make the dependency clearer.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
