For 4# machine independent notes, look in /sys/conf/NOTES. 5 6# directive: machine 7# This directive is mandatory. It defines the architecture to be configured 8# for. It can only be ia64 at this time. 9# 10machine ia64 11 12# directive: cpu 13# You must specify at least one CPU (the one you intend to run on). Deleting 14# the support for CPUs you don't need to use may make parts of the system run 15# faster. There's currently no special code for the different CPUs. Note also 16# that the cpu declares the family. We may need to add support for specifying 17# particular models. 18cpu ITANIUM 19cpu ITANIUM2 20 21# option: IA32 22# This option enables the support for execution of i386 (32-bit) programs on 23# ia64. It is based on the ia32 emulation in the processor. 24options IA32 25 26# option: LOG2_ID_PAGE_SIZE 27# Specify the log2 size of the identity (direct) mappings in regions 6 and 7 28# of the virtual address space. 29options LOG2_ID_PAGE_SIZE=27 # 128M 30 31# option: LOG2_PAGE_SIZE 32# Specify the log2 size of the page to be used for virtual memory management. 33# The page size being equal to 1<<LOG2_PAGE_SIZE. 34options LOG2_PAGE_SIZE=15 # 32K 35 36# option: SKI 37# Build support for running under the ski simulator. 38options SKI 39 40# option: UWX_TRACE_ENABLE 41# Build the unwinder with tracing support.
