FYI:

X1000, CPU: PWRficient PA6T-1682M, kernel 4.20-rc3: grep . /sys/devices/system/cpu/vulnerabilities/*

Code: Select all
/sys/devices/system/cpu/vulnerabilities/l1tf:Not affected
/sys/devices/system/cpu/vulnerabilities/meltdown:Vulnerable
/sys/devices/system/cpu/vulnerabilities/spec_store_bypass:Vulnerable
/sys/devices/system/cpu/vulnerabilities/spectre_v1:Mitigation: __user pointer sanitization
/sys/devices/system/cpu/vulnerabilities/spectre_v2:Mitigation: Software count cache flush


X5000/020, CPU: P5020 (e5500), kernel 4.20-rc3: grep . /sys/devices/system/cpu/vulnerabilities/*

Code: Select all
/sys/devices/system/cpu/vulnerabilities/l1tf:Not affected
/sys/devices/system/cpu/vulnerabilities/meltdown:Not affected
/sys/devices/system/cpu/vulnerabilities/spec_store_bypass:Not affected

Hi,

I reported the PA6T vulnerabilities to the Linux PPC developers today.

Link: https://lists.ozlabs.org/pipermail/linuxppc-dev/2018-November/181780.html

The P5020 CPU doesn’t have any problems with vulnerabilities with the latest Linux kernels! :-)

Have a nice week!

Cheers,
Christian
