From c181159a5b1e1e75474764c6e45b1273a8834728 Mon Sep 17 00:00:00 2001 From: Yong Zhao Date: Thu, 1 Aug 2019 22:55:50 -0400 Subject: [PATCH] drm/amdkfd: Fill the name field in node topology with asic name v2 The name field in node topology has not been used. We re-purpose it to hold the asic name, which can be queried by user space applications through sysfs.
