...
Nuke PIL_IMP.

Remove the use of splimp() from the NetBSD kernel. splnet()
...
and only splnet() is allowed for the protection of data structures
used by network devices.

Make sure everybody has an splvm() and equate it with splimp() (splimp()
...
is the historical name for this interrupt level, and the historical name
is going to go away in the near future).

Add new spl level for tadpole devices splts102.

Device entrypoints for tctrl device (tadpole micro controller)
add header for direct-access ioctl to the tadpole microcontroller.

Change spl calls to always raise priority, except for the ones which are
...
specifically supposed to lower it.
1999-08-05 21:16:55 +00:00
eb20bbc780
Change the semantics of splsoftclock() to be like other spl*() functions,
...
that is priority is rasied. Add a new spllowersoftclock() to provide the
atomic drop-to-softclock semantics that the old splsoftclock() provided,
and update calls accordingly.
This fixes a problem with using the "rnd" pseudo-device from within
interrupt context to extract random data (e.g. from within the softnet
interrupt) where doing so would incorrectly unblock interrupts (causing
all sorts of lossage).
XXX 4 platforms do not have priority-raising capability: newsmips, sparc,
XXX sparc64, and VAX. This platforms still have this bug until their
XXX spl*() functions are fixed.

stdarg.h, varargs.h, psl.h, autoconf.h: posted patches from torek
...
cpu.h: cpu_adjstack() won't work well in the NetBSD execve - need a
different model, stub enablertclock() for now..
exec.h: a netbsd-type exec.h file (ie. empty)
param.h: add MID_MACHINE
pmap.h: delete kernel_pmap hack - it doesn't work for us, + two proto's
vmparam.h: VM_MIN_ADDRESS = 0!
