I would check MIPS as it might have similar PTE bits as well (FOR, FOW) (ma= ny=20 Alpha things are similar to MIPS). I don't have my See MIPS Run handy or I= =20 would check it myself. It might be better to replace the loop with a=20 vm_fault(..., VM_FAULT_DIRTY) though if that would have the same effect. =2D-=20 John Baldwin From owner-freebsd-alpha@FreeBSD.ORG Thu May 14 17:06:36 2009 Return-Path: Delivered-To: freebsd-alpha@freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:4f8:fff6::34]) by hub.freebsd.org (Postfix) with ESMTP id B21DB106564A; Thu, 14 May 2009 17:06:36 +0000 (UTC) (envelope-from des@des.no) Received: from tim.des.no (tim.des.no [194.63.250.121]) by mx1.freebsd.org (Postfix) with ESMTP id 749008FC1F; Thu, 14 May 2009 17:06:36 +0000 (UTC) (envelope-from des@des.no) Received: from ds4.des.no (des.no [84.49.246.2]) by smtp.des.no (Postfix) with ESMTP id C62F56D41B; Thu, 14 May 2009 18:50:34 +0200 (CEST) Received: by ds4.des.no (Postfix, from userid 1001) id A6B71844BD; Thu, 14 May 2009 18:50:34 +0200 (CEST) From: =?utf-8?Q?Dag-Erling_Sm=C3=B8rgrav?= To: John Baldwin References: <86tz3o4lb9.fsf@ds4.des.no> <200905140807.35680.jhb@freebsd.org> Date: Thu, 14 May 2009 18:50:34 +0200 In-Reply-To: <200905140807.35680.jhb@freebsd.org> (John Baldwin's message of "Thu, 14 May 2009 08:07:35 -0400") Message-ID: <86preb39yd.fsf@ds4.des.no> User-Agent: Gnus/5.13 (Gnus v5.13) Emacs/23.0.92 (berkeley-unix) MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable Cc: hackers@freebsd.org, freebsd-alpha@freebsd.org Subject: Re: PTE modified bit emulation trap X-BeenThere: freebsd-alpha@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Porting FreeBSD to the Alpha List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 14 May 2009 17:06:37 -0000 John Baldwin writes: > It might be better to replace the loop with a=20 > vm_fault(..., VM_FAULT_DIRTY) though if that would have the same effect. That was going to be my next question: there must be a more elegant way of doing this :) DES --=20 Dag-Erling Sm=C3=B8rgrav - des@des.no
