With this summary paper https://arxiv.org/abs/1811.05441 it should be possible to take the manual for your favourite CPU and see which exploitable optimizations it does have, and how are these exploits mitigated. Thanks Michal Hi Michal, Thanks for the hint. Here is the status of our machines: FYI: X1000, CPU: PWRficient PA6T-1682M, kernel 4.20-rc3: grep . /sys/devices/system/cpu/vulnerabilities/* /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/* /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 /sys/devices/system/cpu/vulnerabilities/spectre_v1:Mitigation: __user pointer sanitization /sys/devices/system/cpu/vulnerabilities/spectre_v2:Mitigation: Software count cache flush The PA6T is still vulnerable.
