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
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.

Latencytop was removed from oe-core: https://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=bcbc7bbc4fb967d8d4ae6333f71b73491a80b94e latencytop: remove recipe Last commit and release were in 2009; website is down; it's a dead project.
