For what it's worth, I did an comparison of the numbers Shubham posted
in another thread for the JIT, comparing the eBPF interpreter with his
new JIT. The post is here:

Hi Florian,
It would be great if you could help me with it.
Currently, what I am doing is.
root@arm$ ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make -j4
Then I am using Busybox to build the root filesystem
root@arm$ qemu-system-arm -M vexpress-a9 -dtb
./linux/arch/arm/boot/dts/vexpress-v2p-c

Sorry, i don't have a v6.
Maybe try kzm with qemu-system-qemu?

Hi Andrew,
My Apologies.
I will remove the #ifdef CONFIG_CPU_LITTLE_ENDIAN. Do you have the
ARMv6 machine you can test it on?

Hi Shubham
Please don't top post.

#ifdef CONFIG_CPU_LITTLE_ENDIAN
Since i said, ARM does not seem to use it.

Hi Andrew,
I am attaching the latest patch which should work on ARMv5 , ARMv6 and ARMv7.
Please test on your machines. Apologies for the last patch. This patch
should work though.

Hi Andrew,
I am attaching the additional patch to make it work for ARMv5 as well.
Let me know if you find any issues with this.
Please apply 0002-Editted-for-ARMv5-compilation.patch after applying
the first patch.

Hi Andrew,
I think I forgot to compile it for ARMv5. Let me send the patch again
in few minutes.
I appreciate the help.

The JIT compiler emits ARM 32 bit instructions. Currently, It supports
eBPF only. Classic BPF is supported because of the conversion by BPF
core.
JIT is enabled with
echo 1 > /proc/sys/net/core/bpf_jit_enable
Constant Blinding can be enabled along with JIT using
echo 1 > /proc/s
