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
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.
- every pci device which implements _PRT acpi method is considered to
be a pci-to-pci bridge
- acpi driver constructs a hierarchy of pci-to-pci bridges
- when pci driver identifies a pci-to-pci bridge it tells acpi driver
what is the primary and the secondary bus for this device
- when pci requests IRQ routing information from acpi, it passes the
bus number too to be able to identify the device accurately
- 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
