which bustype should be attached with a specific call to config_found()
(from a "mainbus" or a bus bridge).
Do it for isa/eisa/mca and pci/agp for now. These buses all attach to
an mi interface attribute "isabus", "eisabus" etc., and the autoconf
framework now allows to specify an interface attribute on config_found()
and config_search(), which limits the search of matching config data
to these which attach to that specific attribute.
So we basically have to call config_found_ia(..., "foobus", ...) where
such a bus is attached.
As a consequence, where a "mainbus" or alike also attaches other
devices (eg CPUs) which do not attach to a specific attribute yet,
we need at least pass an attribute name (different from "foobus") so
that the foo bus is not found at these places. This made some minor
changes necessary which are not obviously related to the mentioned buses.
Fix some non-initialized variables
close the output files when done
Redo the printing for RCS strings so they don't expand in the awk script too
Do proper tests for variables existance before accessing
Verified output from all scripts is identical to original versions
kqueue provides a stateful and efficient event notification framework
currently supported events include socket, file, directory, fifo,
pipe, tty and device changes, and monitoring of processes and signals
kqueue is supported by all writable filesystems in NetBSD tree
(with exception of Coda) and all device drivers supporting poll(2)
based on work done by Jonathan Lemon for FreeBSD
initial NetBSD port done by Luke Mewburn and Jason Thorpe
This merge changes the device switch tables from static array to
dynamically generated by config(8).
- All device switches is defined as a constant structure in device drivers.
- The new grammer ``device-major'' is introduced to ``files''.
device-major <prefix> char <num> [block <num>] [<rules>]
- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.
- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.
- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.
- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.
- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.
since BTLB entries can be scarce and very little of an I/O subsystem normally
needs to be mapped.
Instead, the pmap now allows mappings of I/O space to be entered with
pmap_kenter_pa. bus_space mappings for small amounts of I/O space (as for
virtually all devices) are made this way, with BTLB entries still used for
large mappings for things like framebuffers.
This has led to more and cleaned-up uses of bus_space(9) and has caused
some autoconf cleanup. Also, kgdb is now attached and connected before
autoconfiguration, which is much earlier than before.
they contain. IRQ information for these has been removed from the
kernel configuration file. GSC bus chips now choose an available CPU
IRQ for themselves, and know IRQ information for all of the devices
they may contain. Minor autoconfiguration changes support this.
Renamed the old-style vmstat interrupt counters to say "ipl" and not
"irq", since they've been disconnected from irq numbers. Also provide
a function to allocate an irq bit from an interrupt register, and a
function to report the next ipl bit that will be allocated.
maps it with BTLB entries, to minimize the number of BTLB entries
needed.
Because the CPU type was often guessed incorrectly, the mapping of
HP board number to system name now includes information about the
expected CPU type.
