From 8fbb19051ea598ad3c2cdd6dcc4ace944c7b2e06 Mon Sep 17 00:00:00 2001 From: Michael Reed Date: Wed, 14 Jun 2023 14:29:11 -0500 Subject: [PATCH] UBUNTU: [Config] Intel Sapphire Rapids HBM support needs CONFIG_NUMA_EMU BugLink: https://bugs.launchpad.net/bugs/2008745 Currently Ubuntu kernel has this kernel config disabled. But in some cases, Intel's Sapphire Rapids High Bandwith Memory (SPR-HBM) needs this option. Memory bandwidth has been a bottleneck of increasingly memory bound workloads. Sapphire Rapids plus HBM is specifically targeted to cater to these workloads, traditionally served using overprovisioning of memory devices.
