[ltt-dev] lttng for nommu cpus

[andy]

Hi

I try to investigate performance issues on a cpu (blackfin)  that does
not have mmu.
I have ported a lttng patch, but unfortunately it does not work, as
relayfs is not supported
on mmu-less cpus.
A Call to allocte buffers in relayfs lead to vmap(), which is not
supported on mmu-less
systems

Is there any flavor of lttng that has been reported to work on mmu-less system?
Any links?

Thank you,
Andy
