From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Received: from ale.deltatee.com (ale.deltatee.com. [207.54.116.67]) by gmr-mx.google.com with ESMTPS id tp10si3644326pac.2.2016.06.14.10.02.38 for (version=TLS1_2 cipher=ECDHE-RSA-AES128-GCM-SHA256 bits=128/128); Tue, 14 Jun 2016 10:02:38 -0700 (PDT) From: Logan Gunthorpe Date: Tue, 14 Jun 2016 11:02:20 -0600 Message-Id: Subject: [PATCH v2 0/8] NTB Selftest Script To: Jon Mason , Dave Jiang , Allen Hubbe Cc: Shuah Khan , Sudip Mukherjee , Arnd Bergmann , linux-kernel@vger.kernel.org, linux-ntb@googlegroups.com, linux-kselftest@vger.kernel.org, Logan Gunthorpe List-ID: Changes since v1: 1) Add a comment to explain the *15 in the buf size calculation, as per Allen's feedback. 2) Clean up the changes to the pingpong client as there were some sloppy copying mistakes. 3) Rework the 'link' file in ntb_tool as per Allen's suggestions. I've added a 'link_event' file the works essentially how he's asked. Though, I found no need to use a completion as suggested and the flow is maybe slightly simpler than he's suggested. Just write a boolean to the event file then read to wait for the link to be either up or down. There's still some discussion on the best interface and it's not much work to make additional minor functional changes. 4) Update the selftest script to use the new 'link_event' file. 5) Minor change to the way the selftest script lists devices thanks to Allen's observation. --- I've written a ntb_test.sh script that would probably be useful if it were included in the kernel. This series ends with that script and includes some useful interface improvements and fixes to the existing ntb test modules. Please see each individual commit for more information. They are mostly independent. The series is based off of v4.6 plus the patches I've submitted that have been accepted into ntb-next. They've been run through checkpatch with --strict this time. As always, I'm happy to incorporate any feedback.
