Subject: About swapper_page_dir and processes' page directory
Date: Fri, 18 May 2001 10:47:48 -0700 [thread overview]
Message-ID: <A33AEFDC2EC0D411851900D0B73EBEF766DCD9@NAPA> (raw)
Folks,
Get a question today. Thanks in advance.
As we know, vmalloc and other memory allocation/de-allocation will
change/update
the swapper_page_dir maintain by the kernel.
I am wondering when/how the kernel synchronzie the change to user level
processes' page
directory entries from the 768th to the 1023th.
Those entries get copied from swapper_page_dir when a user process get
forked/created. Does the kernel
frequently update this information every time when the swapper_page_dir get
changed?
Regards,
Mike
