I've read online that there should be vulnerability info (Meltdown, |
| 2 |
Spectre) in /sys under /sys/devices/system/cpu/vulnerabilities but this |
| 3 |
doesn't exist on my PC. |
| 4 |
|
| 5 |
Another place is in /proc/cpuinfo, no info on meltdown/spectre in there |
| 6 |
either. |
| 7 |
|
| 8 |
Yet another place is in dmesg, (grep 'page tables isolation') nothing |
| 9 |
there either. |

I've updated to gentoo-sources-4.9.76-r1, shouldn't this info be present? |

$ zgrep PAGE_TABLE_ISO /proc/config.gz |
| 18 |
CONFIG_PAGE_TABLE_ISOLATION=y |
| 19 |
|

Or does the page table isolation need to be explicitly turned on? |
