Subject: [PATCH] x86: Do not check FSRM in tst-cpu-features-cpuinfo
Date: Mon, 22 Feb 2021 11:04:58 +0100 [thread overview]
Message-ID: <87sg5o7705.fsf@oldenburg.str.redhat.com> (raw)
Current kernels do not report this feature bit, so the test fails
if the hardware supports it.
According to
[PATCH v2] i386: Add the support for AMD EPYC 3rd generation processors
<https://lists.gnu.org/archive/html/qemu-devel/2021-02/msg03370.html>
some AMD processors set this CPUID bit.
