Subject: RSE Behavior on Interruptions
Date: Mon, 18 Feb 2008 13:32:10 +0000	[thread overview]
Message-ID: <47B988DA.3020807@bull.net> (raw)

Let's assume a user program just has been interrupted.
The RSE can continue spilling/filling registers on behalf of the interrupted user.
Let's assume the RSE engine touches a swapped out page.
As PSR.ic is 0, the page fault cannot be captured correctly.

Can this scenario happen to the current Linux kernel implementation?

Thanks,

Zoltan Menyhart
