| |
The meltdown/spectre vulnerabilities affect several architectures and people are asking for a common way to figure out whether a system is affected or not.
Create
/sys/devices/system/cpu/vulnerabilites
and the files
/sys/devices/system/cpu/vulnerabilites/meltdown /sys/devices/system/cpu/vulnerabilites/spectre_v1 /sys/devices/system/cpu/vulnerabilites/spectre_v2
Add the x86 implementation which shows:
meltdown Mitigation: PTI spectre_v1 Vulnerable sepctre_v1 Vulnerable
On an AMD CPU the output of meltdown is: Not affected.
If PTI is turned off and the CPU is affected of meltdown the output becomes: Vulnerable
That series applies on top of
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86/pti
Thanks,
tglx
