[lttng-dev] Using LTTng on Linux Kernel 2.6.33.7-rt29

[Sylvain Sauvage]

Hi everyone,

 

We are using a Linux 2.6.33.7 with RT patches  version rt29.

It is my understanding that the latest versions of LTTng 2.0 do no
longer support kernels before 2.6.38.

 

As it is not an option for us to move up to a more recent Kernel, we
would like to use the most recent LTTng that is compatible.

 

Could anyone advise the best starting LTTng version that would be
compatible with that Kernel?

The processor we use is an ARM OMAP-L138 (based on the ARMv5 core). Are
there any patches to use (or port) provide the trace clock
functionality?

 

>From the compatibility list here:
http://git.lttng.org/?p=lttv.git;a=blob_plain;f=doc/developer/lttng-lttv
-compatibility.html;hb=HEAD, 

it seems that we could start from 0.216 or 0.217.

 

Please let me know what version you would recommend and suggest extra
patches (related to rt29 or to OMAPL138).

 

Thanks in advance.

Kind Regards,

 

Sylvain
