I really meant to put emphasis on the 'interrupts of any kind' as it actually makes more sense in the security discussion, but anways.lukem95 wrote:nice work
just wondering... what is the security benefit of not using interrupts?
With the lack of IRQ triggers (that I preiously had), no one can plug a keyboard in and start typing, no post-config hotswapping, basically no response to anything except ethernet lines. With that said though, I do poll critical hardware to ensure that it is still working or has been taken (thus reporting an error to an admin about physical problems). I would also like to implement a feature that detects when the case is opened, but that is not a standard, and is specific to manufacturers. I hope that all was legible as I just woek up.01000101 wrote: My OS is now fully Polling based, and no longer supports external interrupts of any kind for security reasons.
