| |
Hello,
Kernel 4.18.5 with old microcode:
[ 0.000000] microcode: microcode updated early to revision 0x2c, date = 2017-03-25 cat /sys/devices/system/cpu/vulnerabilities/meltdown Mitigation: PTI
Kernel 4.18.5 with new microcode (microcode-20180807.tgz), same config:
[ 0.000000] microcode: microcode updated early to revision 0x32, date = 2018-05-11 cat /sys/devices/system/cpu/vulnerabilities/meltdown Not affected
This happens with 4.14.y and 4.9.y as well.
The same with ssb: old microcode: spec_store_bypass:Vulnerable new microcode: spec_store_bypass:Not affected
Is this intentional behavior? I have never seen this on other CPUs, such as Gemini Lake or Baytrail, Haswell etc.
This is a Lenovo Ideapad 120S-11IAP with Apollo Lake N3350 (Goldmont)
Thomas
