# This file contains machine dependent kernel configuration notes.  For
# machine independent notes, look in /sys/conf/NOTES.

# 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: COMPAT_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.
options		COMPAT_IA32

# option: LOG2_ID_PAGE_SIZE
# Specify the log2 size of the identity (direct) mappings in regions 6 and 7
# of the virtual address space.
options 	LOG2_ID_PAGE_SIZE=27		# 128M

# option: LOG2_PAGE_SIZE
# Specify the log2 size of the page to be used for virtual memory management.
# The page size being equal to 1<<LOG2_PAGE_SIZE.
options		LOG2_PAGE_SIZE=15		# 32K

# option: SKI
# Build support for running under the ski simulator.
options		SKI

# option: UWX_TRACE_ENABLE
# Build the unwinder with tracing support. This option is used to debug the
# unwinder itself and the glue around it.
options		UWX_TRACE_ENABLE

# MI options
options		ACPI_DEBUG
options		KSTACK_PAGES=3

Add the bits for a LINT kernel. It has been verified to compile. We may need to polish this. 2003-08-23 21:47:33 +00:00			`# $FreeBSD$`

Catch up with the drive-by renaming of IA32 to COMPAT_IA32. Missed 11 days ago when all the other places were fixed and finally caught by the tinderbox run... 2004-08-27 21:57:00 +00:00			`# option: COMPAT_IA32`

Introduce IA64_ID_PAGE_{MASK\|SHIFT\|SIZE} and LOG2_ID_PAGE_SIZE. The latter is a kernel option for IA64_ID_PAGE_SHIFT, which in turn determines IA64_ID_PAGE_MASK and IA64_ID_PAGE_SIZE. The constants are used instead of the literal hardcoding (in its various forms) of the size of the direct mappings created in region 6 and 7. The default and probably only workable size is still 256M, but for kicks we use 128M for LINT. 2003-09-09 05:59:09 +00:00			`# option: LOG2_ID_PAGE_SIZE`

Change LOG2_PAGE_SIZE from 14 to 15 bits. This will cause the CTASSERT in vm_page.h to be reached and thus slightly increases the overall coverage of LINT on ia64. 2003-08-25 20:02:18 +00:00			`options LOG2_PAGE_SIZE=15 # 32K`

filter out the fdc(4) and sio(4) devices and corresponding options. Note that cy(4) uses COM_MULTIPORT, so we need to keep that option. 2004-05-17 07:03:01 +00:00
Fix typo in comment. While here, end the sentence with a period and remove the empty line between the fdc and sio devices. The empty line suggests that the comment applies to fdc only while it applies to all following devices and options.
