Your Git kernel works in a virtual e5500 machine now! :-) I think we have reached the end of testing! All things are working with your DMA updates. I am looking forward to test your DMA changes in the next merge window again. :-) Cheers Christian From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Received: from mo4-p01-ob.smtp.rzone.de ([85.215.255.51]:18326 "EHLO mo4-p01-ob.smtp.rzone.de" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1727804AbfBLTcE (ORCPT ); Tue, 12 Feb 2019 14:32:04 -0500 Subject: Re: use generic DMA mapping code in powerpc V4 References: <20190204123852.GA10428@lst.de> <20190206151505.GA31065@lst.de> <20190206151655.GA31172@lst.de> <61EC67B1-12EF-42B6-B69B-B59F9E4FC474@xenosoft.de> <7c1f208b-6909-3b0a-f9f9-38ff1ac3d617@xenosoft.de> <20190208091818.GA23491@lst.de> <4e7137db-e600-0d20-6fb2-6d0f9739aca3@xenosoft.de> <20190211073804.GA15841@lst.de> <820bfeb1-30c0-3d5a-54a2-c4f9a8c15b0e@xenosoft.de> <20190212152543.GA24061@lst.de> From: Christian Zigotzky Message-ID: <47bff9d1-7001-4d92-4ad1-e24215b56555@xenosoft.de> Date: Tue, 12 Feb 2019 20:31:56 +0100 MIME-Version: 1.0 In-Reply-To: <20190212152543.GA24061@lst.de> Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: 7bit Content-Language: de-DE Sender: linux-arch-owner@vger.kernel.org List-ID: To: Christoph Hellwig Cc: linux-arch@vger.kernel.org, Darren Stevens , linux-kernel@vger.kernel.org, Julian Margetson , linux-mm@kvack.org, iommu@lists.linux-foundation.org, Paul Mackerras , Olof Johansson , linuxppc-dev@lists.ozlabs.org Message-ID: <20190212193156.aMBdeehKQ4LSWDdYpSsbbwsMy_UF1lMmALeiUxHeF5U@z> On 12 February 2019 at 4:25PM, Christoph Hellwig wrote: > On Tue, Feb 12, 2019 at 01:42:56PM +0100, Christian Zigotzky wrote: >> On 11 February 2019 at 08:38AM, Christoph Hellwig wrote: >>> On Sun, Feb 10, 2019 at 01:00:20PM +0100, Christian Zigotzky wrote: >>>> I tested the whole series today.
