bad ../physical_package_id value about bpi-m64-firmware

[avafinger]

physical_package_id: physical package id of cpu#.
Typically corresponds to a physical socket number, but the actual value is architecture and platform dependent.

Which values would you expect?
I just typed this in my Intel box and they all return 0

[StephaneRenouard]

As this processor has 4 cores, I should expected 0,1,2,3 or 0,0,0,0 for cpu0, cpu1, cpu2 and cpu3.
Theses values are used for thread mapping in software.
I'm trying to run Aerospike software on BPI M64, and this param is checked at runtime. "-1" forbid the software to run.
I cheated with a fake physical_package_id file, but this could be a drawback in the futur.

Can you please try this and see if still the same? It is kernel 3.10.105.

PS: try with the SD CARD if you don't want to format your eMMC.

Kernel 4.11
cat /sys/devices/system/cpu/cpu0/topology/physical_package_id
0

Will look into it when possible.

I'll take the time to try 3.10.105 this weekend. Did you try Kernel 4.11 on BPIM64 ?

[StephaneRenouard]

Ok, I updated the board from 3.10.102 to 3.10.105.

Got the same issue.

yeah, 3.10.x seems to get this value as default for ARM on A64. tested also on Armbian on another A64 (Pine64+). Mainline 4.11 (Armbian) was on other A64 board (OPI). Mainline 4.11.x work bare bone on A64, has no HDMI,CSI and Desktop but you get GbE. 4.11 seems the way to go in this case, but to get fully working, you may need to wait several months....

Update: same issue with 3.10.105. I should have to wait for 4.11...

[avafinger]

If you care only about command line and connectivity (eth0), not sure it eMMC works in 4.11 but seems it is working (i still in the learning curve with 4.x), maybe i get it running in a few weeks, not a promise....

[StephaneRenouard]

Take your time, i'll try the UP board next week from my side.
