Problem with STRICT_DEVMEM

Hi all,

I have a machine running a Linux knl 5.5.8-arch1-1-custom. The only change I have made to the base configuration is disabling CONFIG_STRICT_DEVMEM, as I want to be able to access any block of the physical memory through /dev/mem. However, the behavior of /dev/mem appears to be the same as if the option was enabled: trying to read past the first 1 MiB of data fails. How can I disable the memory protection?

Thanks!
