upgrade to NetBSD CVS release from 2012/10/17 12:00:00 UTC
Makefiles updates to imporve portability
Made sure to be consistent in the usage of braces/parenthesis at
least on a per file basis. For variables, it is recommended to
continue to use braces.
The tested targets are the followgin ones:
* tools
* distribution
* sets
* release
The remaining NetBSD targets have not been disabled nor tested
*at all*. Try them at your own risk, they may reboot the earth.
For all compliant Makefiles, objects and generated files are put in
MAKEOBJDIR, which means you can now keep objects between two branch
switching. Same for DESTDIR, please refer to build.sh options.
Regarding new or modifications of Makefiles a few things:
* Read share/mk/bsd.README
* If you add a subdirectory, add a Makefile in it, and have it called
by the parent through the SUBDIR variable.
* Do not add arbitrary inclusion which crosses to another branch of
the hierarchy; If you can't do without it, put a comment on why.
If possible, do not use inclusion at all.
* Use as much as possible the infrastructure, it is here to make
life easier, do not fight it.
Sets and package are now used to track files.
We have one set called "minix", composed of one package called "minix-sys"
. common/include/arch/i386 is not actually an imported
sys/arch/i386/include but leftover Minix files;
remove and move to include/
. move include/ufs to sys/ufs, where it came from, now that
we have a sys/ hierarchy
. move mdocml/ to external/bsd/, now we have that
. single sys/arch/i386/stand/ import for boot stuff
There is important information about booting non-ack images in
docs/UPDATING. ack/aout-format images can't be built any more, and
booting clang/ELF-format ones is a little different. Updating to the
new boot monitor is recommended.
Changes in this commit:
. drop boot monitor -> allowing dropping ack support
. facility to copy ELF boot files to /boot so that old boot monitor
can still boot fairly easily, see UPDATING
. no more ack-format libraries -> single-case libraries
. some cleanup of OBJECT_FMT, COMPILER_TYPE, etc cases
. drop several ack toolchain commands, but not all support
commands (e.g. aal is gone but acksize is not yet).
. a few libc files moved to netbsd libc dir
. new /bin/date as minix date used code in libc/
. test compile fix
. harmonize includes
. /usr/lib is no longer special: without ack, /usr/lib plays no
kind of special bootstrapping role any more and bootstrapping
is done exclusively through packages, so releases depend even
less on the state of the machine making them now.
. rename nbsd_lib* to lib*
. reduce mtree
1. ack, a.out, minix headers (moved to /usr/include.ack),
minix libc
2. gcc/clang, elf, netbsd headers (moved to /usr/include),
netbsd libc (moved to /usr/lib)
So this obsoletes the /usr/netbsd hierarchy.
No special invocation for netbsd libc necessary - it's always used
for gcc/clang.
This patch moves more includes (most of them, to tell the truth) to
common/include directory. This completes the list of includes needed
to compile current trunk with the new libc (but to do that you need
more patches in queue).
This patch also contains some modification (for compilation with new
headers) to the common includes under __NBSD_LIBC, the define used
in mk script to specialize compilation with new includes.
This patch moves further includes (the network part and lib.h) in common/.
It is the last part to get the netbsd libc to compile under minix. Further moves will be needed as we get the netbsd libc to compile minix itself.
Also, this patch add #ifndef's to termios.h, as it create problems with netbsd's namespace.h.
Headers that will be shared between old includes and NetBSD-like includes
are moved into common/include tree. They are still copied in /usr/include
in 'make includes', so compilation and programs aren't be affected.

- 99% of the code is Intel's ACPICA. The license is compliant with BSD
and GNU and virtually all systems that use ACPI use this code, For
instance it is part of the Linux kernel.
- The only minix specific files are
acpi.c
osminixxf.c
platform/acminix.h
and
include/minix/acpi.h
- At the moment the driver does not register interrupt hooks which I
believe is mainly for handling PnP, events like "battery level is
low" and power management. Should not be difficult to add it if need
be.
- The interface to the outside world is virtually non-existent except
a trivial message based service for PCI driver to query which device
is connected to what IRQ line. This will evolve as more components
start using this driver. VM, Scheduler and IOMMU are the possible
users right now.
- because of dependency on a native 64bit (long long, part of c99) it
is compiled only with a gnu-like compilers which in case of Minix
includes gcc llvm-gcc and clang
