Description Mark 2013-03-26 17:23:24 UTC
latencytop is available for all major archs except MIPS. There seems to be patches floating around to make this support available so it would be nice to collect these and include them in Yocto.

Mark, Please provide an estimate and projected delivery milestone.  Thanks
Comment 2 Mark Hatle 2013-10-18 18:51:18 UTC
Moving to future.  We'd like this, but it's not needed in 1.6.

The below mentioned patch adds latencytop support for MIPS. 

"MIPS: add LATENCYTOP support": https://patchwork.linux-mips.org/patch/11353/

Tested with qemumips (poky master with this patch applied on linux-yocto_4.1.bb) and it works as expected.

the patch mentioned above is in the latest 4.4.89 K.O kernel

https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/commit/arch/mips/kernel/stacktrace.c?h=v4.4.89&id=e1e1611598148e03c6d65e6c23338f4ff2cee71e

Unless there is a userland component needing updating, I would say this now works in pyro/rocko & master.

Last commit and release were in 2009; website is down; it's a dead project.
