Odroid XU3 and PAPI

Post by raditya160053 » Thu Jun 06, 2019 6:11 am

I'm trying to make PAPI work on Odroid XU3(Yes, I use an XU3, we had one in the lab and we need the onboard power sensors for our project).
I've managed to install it, and papi_avail shows 16 events available. but when I run the program and try to count PAPI_TOT_INS, I get the following error,

Code: Select all

PAPI error -7: Event does not exist
Even though the event is available.
dmesg | grep PMU
shows the following,

Code: Select all

[    0.000000] [c0] EXYNOS5422 PMU Initialize
papi_component_avail shows the following message:

Code: Select all

I've never heard about PAPI yet.

Anyway, try other Ubuntu image which has Kernel 4.9 or 4.14.
This latest XU4 image should work with XU3 too.

I checked PAPI on my XU4 (running 4.14.94-1-ARCH, had perf installed before).
just installed papi and it works. besides the kernel version, the output of papi_component_avail looks identical to yours.
so a kernel upgrade might really help.
