given buffer, and if necessary, reducing the display width of the
number to fit in the buffer by increasing the units (from kilobytes
(2^10) through to exabytes (2^60)).
so that devices which must allocate DMA memory in this range (e.g.
PixelStamp graphics boards) have a better chance of doing so, without
an awful hack.
-arrange gateway code to fall back to the old method if the new "getfile"
is not answered (and both are enabled -- allow to switch off the new
method for symmetry)
-handle error if setting the netmask fails
directories and use .PATH to lookup the source files.
(Formerly, the libs were built from the source dirs, with MAKEOBJDIR
set to the compilation directory.)
This solves 2 problems:
-"mkdep" and "make" are now consistent about the file lookup, this fixes
bad interactions with amd reported in PR bin/7374 (Arne Juul) and
lossage reported by Andrew Gillham ("obj" dirs and relative paths still
don't work well together)
-kernel compile trees can be moved around without forcing a new
"make depend" - fixing PR kern/4021 by Martin Husemann
_splraise, _spllower, _splset, _splget, _setsoftintr, _clrsoftintr, _splnone.
They manipulate MIPS processor's 8 interrupt sources and are used
as building blocks for NetBSD spl(9) kernel interface. Note that
MIPS processor doesn't enforce inclusive 'interrupt levels' found
in other processors, then the hierarchal nature of IPL must be
implemented by composing MIPS processor interrupt masks appropriately.
With the simplest target port in which small number of devices are
independently assigned with 6 external interrupt signal lines,
spl(9) kernel interface will be implemented with #define's of
processor interrupt controls mentioned above. In more general
cases, in which target computers have many devices and 'system
registers' indicating pending interrupt sources at any moment,
spl(9) will be implemented with more complex machinary manipulating
processor interrupts and system registers in target port dependent
ways.
- Nuke unused code and reorder locore definitions. XXX Following
routines will be replaced with C language version; setrunqueue,
remrunqueue, switchfpregs, savefpregs, MachFPInterrupt.
