From mboxrd@z Thu Jan 1 00:00:00 1970 From: Manfred Spraul Date: Sat, 11 Mar 2000 09:02:06 +0000 Subject: [Linux-ia64] Q: stack coherency Message-Id: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-ia64@vger.kernel.org Can I access a structure that's stored on the stack of one CPU from another CPU? I'm just noisy because I always did that [e.g SysV message code ipc/msg.c], and now a friend asked me if that's true for all cpu architecures. CPU1: - initialize linked list element [local variable] - spin_lock - add to linked list - spin_unlock - ... CPU2: - spin_lock - walk the linked list - spin_unlock. -- Manfred
