https://jira.whamcloud.com This file is an XML representation of an issue en-us 9.4.14 940014 05-12-2023 https://jira.whamcloud.com/browse/LU-9667 Lustre <p>LNetCtl commands are used to pull information from LNet and display them in YAML format. </p> <p>Also a decision is made to use sysfs for pulling simple key/value pair related information rom kernel and IOCTL for more complex operations. So the new LNetCtl commands will be added based on this.</p> <p>This ticket will track the progress on adding the sysfs infrastructure and the new LNetCtl commands.</p> LU-9667

LNet Kernel/Userspace Interface

New Feature Minor Open Unresolved Sonia Sharma Sonia Sharma Wed, 14 Jun 2017 17:43:50 +0000 Sun, 6 Dec 2020 02:09:30 +0000 0 12 <p>Besides the sysfs work one of the things asked by the linux kernel maintainers is to look to moving from ioctls to the netlink api. I have started to explore this avenue.</p> <p>l looked over your document. I don't think you mean for your stats files to all module parameters do you? You will instead need to create </p> <p>/sys/fs/lnet/...</p> <p>A nice effect of having /sys/fs/lnet/ko2inlnd is that we can link in the tunables that are module parameters as well.</p> <p>James, thanks. I'll update the doc. I'm looking into a way of making the wiki document public, so that it's easier for changes to be visible outside Intel.</p> <p>James, Olaf, the Sysfs Requirements doc has been updated. It's now accessible from here:<br/> <a href="https://wiki.hpdd.intel.com/pages/viewpage.action?pageId=65700164" class="external-link" target="_blank" rel="nofollow noopener">https://wiki.hpdd.intel.com/pages/viewpage.action?pageId=65700164</a></p> <p>You should be able to add comments. The doc should be available for anonymous access as well.</p> <p>Sonia Sharma (sonia.sharma@intel.com) uploaded a new patch: <a href="https://review.whamcloud.com/29163" class="external-link"
