Hi Burt, Thank you for your input. I pushed a new version of my commit (https://gerrit.fd.io/r/#/c/4576/) where I tried to do things more clearly. I had a look here https://github.com/torvalds/linux/blob/master/arch/arm64/kernel/cacheinfo.c and it seems that on arm64, recent kernels should be able return a correct value. Which means that some day, they will. Old ones will fallback to 64 Bytes. Maybe someone who has a thunder platform can try it in order to see what getconf returns him. I tried on my ThunderX system, and it returns 0, but kernel which I’m running is old (one from SDK). I am not able to run standard ubuntu kernel for arm64 on that system, it just freezes very early in the boot process. As ThunderX is listed as certified [1], I guess i’m doing something wrong….
