Subject: [Xenomai-core] User space stack pre-faulting
Date: Wed, 22 Jun 2011 11:26:52 +0200	[thread overview]
Message-ID: <4E01B55C.7030507@domain.hid> (raw)

Hi Gilles,

do you remember reasons for only pre-faulting the main thread's stack?
The desire to avoid wasting resources by forcing all stacks into memory?

I've the requirement on my table to provide a generic solution of all
shadow threads. I think this should be possible using pthread_getattr_np
and walking the stack page-wise, but I may miss some pitfall.
