Vincent Donnefort	ec07906bdc	tracing: selftests: Extend hotplug testing for trace remotes ... The hotplug testing only tries reading a trace remote buffer, loaded before a CPU is offline. Extend this testing to cover: * A trace remote buffer loaded after a CPU is offline. * A trace remote buffer loaded before a CPU is online. Because of these added test cases, move the hotplug testing into a separate hotplug.tc file.

Vincent Donnefort	0a1b03251d	tracing: selftests: Add trace remote tests ... Exercise the tracefs interface for trace remote with a set of tests to check: * loading/unloading (unloading.tc) * reset (reset.tc) * size changes (buffer_size.tc) * consuming read (trace_pipe.tc) * non-consuming read (trace.tc) Cc: Shuah Khan <skhan@linuxfoundation.org> Cc: linux-kselftest@vger.kernel.org Link: https://patch.msgid.link/20260309162516.2623589-16-vdonnefort@google.com Reviewed-by: Steven Rostedt (Google) <rostedt@goodmis.org> Signed-off-by: Vincent Donnefort <vdonnefort@google.com> Signed-off-by: Steven Rostedt (Google) <rostedt@goodmis.org>	2026-03-09 12:33:55 -04:00
