Bug ID: 28090
Summary: elf/tst-cpu-features-cpuinfo-static fails on certain
AMD64 cpus
Product: glibc
Version: 2.34
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: build
Assignee: unassigned at sourceware dot org
Reporter: michael.hudson at canonical dot com
CC: carlos at redhat dot com
Target Milestone: ---
Some (but not all, for added fun) Launchpad builders have these CPUs:
processor : 0
vendor_id : AuthenticAMD
cpu family : 23
model : 1
model name : AMD EPYC 7351 16-Core Processor
stepping : 2
microcode : 0x1000065
cpu MHz : 2395.494
cache size : 512 KB
physical id : 0
siblings : 1
core id : 0
cpu cores : 1
apicid : 0
initial apicid : 0
fpu : yes
fpu_exception : yes
cpuid level : 13
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov
pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext fxsr_opt pdpe1gb rdtscp

rdseed adx smap clflushopt xsaveopt xsavec xgetbv1 virt_ssbd arat npt nrip_save
bugs : fxsave_leak sysret_ss_attrs null_seg spectre_v1 spectre_v2
spec_store_bypass
bogomips : 4790.98
TLB size : 1024 4K pages
clflush size : 64
cache_alignment : 64
address sizes : 40 bits physical, 48 bits virtual
power management:
And on these CPUs elf/tst-cpu-features-cpuinfo-static fails like this:
Checking HAS_CPU_FEATURE (AMD_SSBD):
HAS_CPU_FEATURE (AMD_SSBD): 0
cpuinfo (ssbd): 1
*** failure ***
This seems to be the same failure as
https://sourceware.org/pipermail/libc-alpha/2021-February/122227.html but I'm
not sure there was any follow up to that mail.
