Hi,
In the current upstream mainline kernel, perf record --call-graph dwarf
is not supported for architecture mips64. I find the following related
patches about this feature by David Daney <david.daney@xxxxxxxxxx> and
Archer Yan <ayan@xxxxxxxxxxxx> in Sep 2019.
AFAIK ddaney left Cavium at 2018 and Wave Computing Shanghai is defuncted...
Feel free to take over if you like, there is no licenses issue, just
remember to credit
others properly.

[2/2] Support extracting off-line stack traces from user-space with perf
https://lore.kernel.org/patchwork/patch/1126520/
Is this a work in progress?
Could you please give me some feedback?
Thank you for your help.
Thanks,
