and attach the secondary pci bus as a 'pci' device. Note that this support
is incomplete and will not yet work for ports other than that i386. (The
i386 can rely on the PCI interrupt 'line' information to determine
interrupt mapping, which is not necessarily possible on other systems.)
works with the revamped machine-independent TC code in sys/dev/tc.
A name change is necessary to avoid a name clash with sys/dev/tc/tc.c,
which also creates a tc.o.
of bwtwo, cgfour, cgsix, and cgeight. Includes support for attaching
the overlay plane of the cgfour and cgeight as a bwtwo instance (a'la
SunOS).
P4 register descriptions, cgfour driver, and cgeight driver partially
derived from OpenBSD.
This code may still need polishing.
bus support want to attach to should be declared in conf/files, so that
hairy ordering constraints on the inclusions of busses' "files" files
in files.{MACHINE} are avoided. isabus, pcibus attributes will go here later.
The problem is, for instance, that there are some devices in files.isa
currently which require that 'pci' be defined, but there are some PCI
devices (e.g. 'sio' on the Alpha) that provide isabus interfaces, i.e.
'isa' busses attach to them. Unless the the bus-attachment attributes
are here, it's impossible to declare the busses' files and attribute
dependencies in a machine-independent way.
argument list. This allows easy 'submatching', which will eliminate a fair
bit of slightly tricky duplicated code from various busses. config_found()
is now a #define in sys/device.h, which invokes config_found_sm().
and the "kernel.tar.Z" distribution on louie.udel.edu, which is older than
xntp 3.4y or 3.5a, but contains newer kernel source fragments.
This commit adds support for a new kernel configuration option, NTP.
If NTP is selected, then the system clock should be run at "HZ", which
must be defined at compile time to be one value from:
60, 64, 100, 128, 256, 512, 1024.
Powers of 2 are ideal; 60 and 100 are supported but are marginally less
accurate.
If NTP is not configured, there should be no change in behavior relative
to pre-NTP kernels.
These changes have been tested extensively with xntpd 3.4y on a decstation;
almost identical kernel mods work on an i386. No pulse-per-second (PPS)
line discipline support is included, due to unavailability of hardware
to test it.
With this in-kernel PLL support for NetBSD, both xntp 3.4y and xntp
3.5a user-level code need minor changes. xntp's prototype for
syscall() is correct for FreeBSD, but not for NetBSD.
