Description ruben 2023-04-11 09:10:25 UTC 
I’m trying out the new kTLS support in FreeBSD. On amd64 I can load the kernel module, but on arm64 it fails with

kldload ktls_ocf
kldload: can't load ktls_ocf: No such file or directory

And dmesg shows

link_elf: symbol sysctl___kern_ipc_tls_stats undefined

Commit f9322ff6efa508df8368e31e3c4880cff11b0e23 which adds KERN_TLS to GENERIC on arm64 hasn't been merged to stable/13.  You can likely just add KERN_TLS and rebuild your kernel and have it work.  Probably that commit should be MFC'd to stable/13.
Comment 2 ruben 2023-04-18 09:26:18 UTC 
Thanks, I was under the impression that with exception of certain hardware related differences both amd64/arm64 kernels would have the same options. I’ll compile a custom kernel for now and wait to see the option to be added in e.g. 13.3

In general they should. I'll take a look at this one.
