2021-08-24	platform-msi: Add ABI to show msi_irqs of platform devices	Barry Song	1	-0/+14
	PCI devices expose the associated MSI interrupts via sysfs, but platform devices which utilize MSI interrupts do not. This information is important for user space tools to optimize affinity settings. Utilize the generic MSI sysfs facility to expose this information for platform MSI.

2020-07-10	driver core: platform: expose numa_node to users in sysfs	Barry Song	1	-0/+10
	Some platform devices like ARM SMMU are memory-mapped and populated by ACPI/IORT. In this case, NUMA topology of those platform devices are exported by firmware as well. Software might care about the numa_node of those devices in order to achieve NUMA locality. This patch will show the numa_node for this kind of devices in sysfs. For those platform devices without numa, numa_node won't be visible.

2014-07-09	driver core: platform: add device binding path 'driver_override'	Kim Phillips	1	-0/+20
	Needed by platform device drivers, such as the upcoming vfio-platform driver, in order to bypass the existing OF, ACPI, id_table and name string matches, and successfully be able to be bound to any device, like so: echo vfio-platform > /sys/bus/platform/devices/fff51000.ethernet/driver_override echo fff51000.ethernet > /sys/bus/platform/devices/fff51000.ethernet/driver/unbind echo fff51000.ethernet > /sys/bus/platform/drivers_probe This mimics "PCI: Introduce new device binding path using pci_dev.driver_override", which is an interface enhancement for more deterministic PCI device binding, e.g., when in the presence of hotplug.
