Hi, I am in the process of porting a Linux device driver to FreeBSD. In Linux, a large block of RAM (256MB) is reserved by using the 'mem=' and 'memmap=' arguments to the kernel. In the device driver, ioremap() is used to map this memory into kernel virtual memory. In FreeBSD contigmalloc() is available but due to the large amount of physical memory required this may not work reliably. Is there an existing method to reserve a large block of RAM early in the boot process?
