From 8785968bce1cc7368ea95c3e1e5b9210f56f6667 Mon Sep 17 00:00:00 2001 From: Mike Travis Date: Tue, 10 Sep 2019 09:58:44 -0500 Subject: x86/platform/uv: Add UV Hubbed/Hubless Proc FS Files Indicate to UV user utilities that UV hubless support is available on this system via the existing /proc infterface. The current interface is maintained with the addition of new /proc leaves ("hubbed", "hubless", and "oemid") that contain the specific type of UV arch this one is.
