The driver apparently assumes that the device uses the same page size as the CPU, but also assumes that this is 4096 bytes. On architectures with a larger page size like 65536 bytes, we get a warning about an integer overflow: drivers/media/pci/intel/ipu3/ipu3-cio2.c: In function 'cio2_fbpt_entry_init_dummy': arch/arm64/include/asm/page-def.h:28:20: error: large integer implicitly truncated to unsigned type [-Werror=overflow] #define PAGE_SIZE (_AC(1, UL) << PAGE_SHIFT) ^ drivers/media/pci/intel/ipu3/ipu3-cio2.h:404:26: note: in expansion of macro 'PAGE_SIZE' #define CIO2_PAGE_SIZE PAGE_SIZE ^~~~~~~~~ drivers/media/pci/intel/ipu3/ipu3-cio2.c:172:3: note: in expansion of macro 'CIO2_PAGE_SIZE' CIO2_PAGE_SIZE / sizeof(u32) * CIO2_MAX_LOPS; Obviously this won't work, but the driver is also unlikely to ever be used on such an architecture, so the easiest workaround is to define the CIO2_PAGE_SIZE macro to the size that the hardware actually uses.
