Documentation : Update relay function types

2018-07-10T21:11:00+00:00

This patch updates two callback functions provided as an example in relay API documentation : subbuf_start and create_buf_file_handler. These functions were using older and incorrect types causing an "initialization from incompatible pointer type". Signed-off-by: Yohan Pipereau Signed-off-by: Jonathan Corbet

relay: add buffer-only channels; useful for early logging

2008-07-26T19:00:04+00:00

Allows one to create and use a channel with no associated files. Files can be initialized later. This is useful in scenarios such as logging in early code, before VFS is up. Therefore, such channels can be created and used as soon as kmem_cache_init() completed. This is needed by kmemtrace to do tracing in early kernel code.

[PATCH] Relay: add CPU hotplug support

2007-02-11T18:51:28+00:00

Mathieu originally needed to add this for tracing Xen, but it's something that's needed for any application that can be tracing while cpus are added. unplug isn't supported by this patch. The thought was that at minumum a new buffer needs to be added when a cpu comes up, but it wasn't worth the effort to remove buffers on cpu down since they'd be freed soon anyway when the channel was closed.

[PATCH] Documentation update for relay interface

2006-08-27T18:01:31+00:00

Here's updated documentation for the relay interface, rewritten to match the relayfs->relay changes. It also moves relayfs.txt to relay.txt in the process. It includes the changes to relayfs.txt previously posted by Randy Dunlap, thanks for those. The relay-apps examples have also been updated to match, and can be found on the sourceforge relayfs website.
