# This file contains machine dependent kernel configuration notes. For

# directive: machine
# This directive is mandatory. It defines the architecture to be configured
# for. It can only be ia64 at this time.
#
machine ia64
# directive: cpu
# You must specify at least one CPU (the one you intend to run on). Deleting
# the support for CPUs you don't need to use may make parts of the system run
# faster. There's currently no special code for the different CPUs. Note also
# that the cpu declares the family. We may need to add support for specifying
# particular models.
cpu ITANIUM
cpu ITANIUM2
# option: IA32
# This option enables the support for execution of i386 (32-bit) programs on
# ia64. It is based on the ia32 emulation in the processor.

# Specify the log2 size of the identity (direct) mappings in regions 6 and 7
# of the virtual address space.

# option: LOG2_PAGE_SIZE
# Specify the log2 size of the page to be used for virtual memory management.
