Please provide packaging for vclog

On 64-bit Raspberry Pi OS, there are three ways to get the VC logs:
- statically linked vcdbg from some Google Drive
- dynamically linked vcdbg from the armhf repo, needs additional armhf libraries to work
- compile vclog yourself
It would be great to have vclog available as Debian package in the Raspberry Pi OS repositories.
Thank you!

You should be able to install raspi-utils to get vclog now.

Yes, thank you. However, it seems that vclog doesn't work with older kernels:
root@pi-test-1:# vclog -a
Could not read from Device Tree log starts and log size
root@pi-test-1:# vclog -m
Could not read from Device Tree log starts and log size
raspberrypi-bootloader 1:1.20220331-1
raspberrypi-kernel 1:1.20220331-1

It does work perfectly with the current kernel:
root@pi-test-1:~# vclog -a
No messages available
raspberrypi-kernel 1:1.20230106-1
raspberrypi-bootloader 1:1.20230106-1
root@pi-test-1:~# uname -a
Linux pi-test-1 5.15.84-v8+ #1613 SMP PREEMPT Thu Jan 5 12:03:08 GMT 2023 aarch64 GNU/Linux
Would it make sense to add a dependency on a minimum kernel version to raspi-utils?

It won't be the kernel version - try updating the firmware.

This can probably be closed now, as vclog is included by default in both 32-bit and 64-bit versions of Raspberry Pi OS Bookworm.
