How exactly would it match the host? Does uname -r report host information or container information?

It has to be host, Docker isn't a real VM and uses the host kernel. Note I did zero research.

Ok I did minimal research https://stackoverflow.com/questions/31012297/uname-a-returning-the-same-in-docker-host-or-any-docker-container

Docker uses the host operating system kernel, there is no custom or additional kernel inside the container. All containers running on the machine are sharing this "host" kernel.

Yep, I tested this locally - kernel reported in docker was exactly like my host.

I pulled sycl image, where linux-tools package was installed (in version A), then run apt install -y linux-tools-$(uname -r) in docker and new version B appeared and perf started to work.

Also, as I mentioned above - I tested this on BMG machine with other kernel and worked as well (https://github.com/intel/llvm/actions/runs/18881499077/job/53887826008?pr=20493#step:19:726)
