From 4107248c5615ab20b64073f2dd5917b3961239dc Mon Sep 17 00:00:00 2001 From: Oliver O'Halloran Date: Mon, 15 Jul 2019 18:56:10 +1000 Subject: [PATCH] powerpc/eeh_sysfs: ifdef pseries sr-iov sysfs properties 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.
