<h1>20160331 - Instant Soft-Reboot to Prior Machine Snapshot</h1>
|
|
<br>
|
|
|
|
An idea for practical simple memory protection on an otherwised unprotected system.
|
|
Works similar in concept to emulator instant save and restore but applied to a full system.
|
|
Reserve 50% of memory for a full machine state snapshot.
|
|
Deny access to this snapshot memory except during save and restore (ie pages just not in page table).
|
|
Hook up hotkey combination to save or restore full machine state.
|
|
On crash, simply restore from snapshot (instant soft-reboot).
|
|
Design around one full machine barrier per frame for safe snapshot point.
