For 4# machine independent notes, look in /sys/conf/NOTES. 5 6# directive: cpu 7# You must specify at least one CPU (the one you intend to run on). Deleting 8# the support for CPUs you don't need to use may make parts of the system run 9# faster. There's currently no special code for the different CPUs. Note also 10# that the cpu declares the family. We may need to add support for specifying 11# particular models. 12cpu ITANIUM 13cpu ITANIUM2 14 15# option: COMPAT_IA32 16# This option enables the support for execution of i386 (32-bit) programs on 17# ia64. It is based on the ia32 emulation in the processor. 18options COMPAT_IA32 19 20# option: LOG2_ID_PAGE_SIZE 21# Specify the log2 size of the identity (direct) mappings in regions 6 and 7 22# of the virtual address space. 23options LOG2_ID_PAGE_SIZE=27 # 128M 24 25# option: LOG2_PAGE_SIZE 26# Specify the log2 size of the page to be used for virtual memory management. 27# The page size being equal to 1<<LOG2_PAGE_SIZE. 28options LOG2_PAGE_SIZE=15 # 32K 29 30# option: SKI 31# Build support for running under the ski simulator. 32options SKI 33 34# option: UWX_TRACE_ENABLE 35# Build the unwinder with tracing support.
