cat /proc/cpuinfo | grep pti
- fermienrico 9y agoWhat is the expected outcome if its patched vs. not? I am getting: fpu_exception : yes
- AbacusAvenger 9y agoYou should see "pti" on the "flags" line of /proc/cpuinfo. You apparently don't, so you don't have page table isolation.
- ComputerGuru 9y agoNo, he shouldn’t be seeing that regardless as it doesn’t match the grep regex. I don’t know what, though. Edit: facepalm. Or should that be foot-in-mouth?
- sowpati 9y agoIt does match the regex. "pti" is a substring in "exception"
- ComputerGuru 9y agoThanks. I feel stupid, I looked that line up, down, and sideways for a match :/
- ComputerGuru 9y agoI was wrong

- fermienrico 9y agoI currently have the following system (up-to-date): Ubuntu 16.04.3 LTS (GNU/Linux 4.4.0-104-generic x86_64) I ran the following command: sudo cat /proc/cpuinfo | grep pti which returned: fpu_exception : yes Note the instance of 'pti' in the word 'exception'.
