x86/platform/uv: Add new uv_sysfs platform driver (4fc2cf1f) · Commits · 戴 / test

Add the uv_sysfs driver to construct a read-only sysfs interface at /sys/firmware/sgi_uv/ to expose information gathered from UV BIOS. This information includes: * UV Hub descriptions, including physical location * Cabling layout between hubs on the fabric * PCI topology, including physical location of PCI cards Together, the information provides a robust physical description of a UV system, useful for correlating to performance data or performing remote support.
