//! Invoke page_fault_handler() on the CowExt to run the COW process
|
||||
//! If the method above returns true, the COW process is executed, else do your own things.
|
||||
//!
|
||||
//! To implement the CowExt, we added a "shared state" to the page table entry
|
||||
//! We use 2bits in the entry for "readonly and shared" and "writable and shared"
|
||||
//! For CPU, the page of the entry is present and readonly,
|
||||
//! and it's possible to read the page through different page tables
|
||||
//! but when the page is writen, the page fault will be triggered.
|
||||
//! When page fault is triggered, the page_fault_handler() on the CowExt should be invoked.
|
||||
//! In the page_fault_handler() method, we return false if the page is accurately readonly.
|
||||
//! Elsewise we copy the data in the page into a newly allocated frame,
|
||||
//! and modify the page table entry to map the page to the frame, and set the present and writable bit.
|
||||
//!
|
||||
//! A frame can have write and read reference at the same time,
|
||||
//! so we need to maintain the count of write and read reference.
|
||||
//! When page fault occurs, if the read reference count is 0 and the write reference count is 1，
|
||||
//! The copy process should be skipped and the entry is mark as writable directly.
