Building linux-tools/perf from kernel sources on a custom build

So I'm fairly new to Armbian (although I have already managed to successfully create a custom build with most of what I need). Sadly, I've very much hit a blocker. I really need to use linux-tools/perf on an RK3588 board with a vendor kernel (I'm using the Mali OpenCL, and the ARM packages are mostly locked) and I need to do some performance tuning. I cannot figure out how to get these tools deployed. 

 

1. There are no linux-tools packages build -- which is fair enough, I'm probably in a minority. Some parts of the tools directories are culled during a cleaning process for the headers, I can see that

2. I am happy to copy over the kernel source and build on the device, but this is a patched vendor kernel. Can I just rsync across `cache/sources/linux-kernel-worktree`? Is that the patched kernel source tree?

3. There are some old allusions in the forums to using armbian-config to get sources -- I'm guessing that's long deprecated

4. Would it be appropriate at some point to create a .deb for the actual kernel sources, just in case -- or even, ideally, the linux-tools packages themselves?

 

I am very happy to invest effort into helping make this happen, but I am starting from cold into this fairly complex build infrastructure, so any help or pointers I'd be extremely grateful.
