Unable to build at aarch64

Hi @omikron88

It works for me on Ubuntu 23.04, on a Raspberry 4, Linux kernel 6.2. See the log below. It also works on the same Ubuntu version on a VM running on a MacBook M1.

I see that your logs mention the kernel 5.10 (older). There is maybe an issue with this version of the kernel but I have no other Arm64 system with that version.

Hi @omikron88

I also tried on a Debian 11.7 VM on the MacBook M1, with kernel 5.10 and gcc 10.2, and it works correctly, the driver is built and loaded. So, this does not seem to be a kernel version issue.

I looked into my dkms make.log files. I see the same warnings as you, with kernels 5.10 and 6.2, but the build completes successfully.

However, in your log file, each warning is followed by "error, forbidden warning". Do you use some special kernel configuration? Your kernel is identified as "5.10.110-rockchip-rk3588". There is probably some special configuration with this one which fails on these warnings. I mentioned that it works with a "standard" Raspberry Pi 4, which is a similar type of system.
