Subject: DYNAMIC_FTRACE and I-pipe patch
Date: Tue, 5 Mar 2024 00:43:46 +0100 [thread overview]
Message-ID: <CAFc1U0sy7hK6-4_BiC6npmSduU2XMJNQjBAR3GnkX9bqkW4MVg@mail.gmail.com> (raw)
Hi,
One of my customers uses a 5.4.70 kernel with an iMX8M board and a
custom I-pipe patch (with Xenomai 3.1). It looks like all the I-pipe
patches disable the DYNAMIC_FTRACE option :
diff --git a/kernel/trace/Kconfig b/kernel/trace/Kconfig
index f3f2fc8ad81a..98d7c64b7b8f 100644
--- a/kernel/trace/Kconfig
+++ b/kernel/trace/Kconfig
@@ -532,6 +532,7 @@ config DYNAMIC_FTRACE
bool "enable/disable function tracing dynamically"
depends on FUNCTION_TRACER
depends on HAVE_DYNAMIC_FTRACE
+ depends on !IPIPE
default y
help
This option will modify all the calls to function tracing
That's not the case for a recent Dovetail based kernel.
Could you give me some information about such a limitation ?
Thanks in advance.
regards

I would love to change the world, but they won't give me the source code
