32b Compilation output the below error:

error: format '%lx' expects argument of type 'long unsigned int', but
argument 8 has type 'off_t' [-Werror=format=]

off_t would have same size as pointer.
Changing lx to PRIxPTR would work?

'off_t' is no more same size as pointer, please check [1], otherwise what you
said correct and code was working fine previously.

Briefly, from build system we are asking/forcing off_t to be always 64-bit

Ahh, sorry I see what you mean after checking the patch J
You are right, I thinks patch should be something like:

 -               DRV_LOG(DEBUG, "port %u: uar_mmap_offset 0x%lx",
 +               DRV_LOG(DEBUG, "port %u: uar_mmap_offset 0x%"PRIx64,
