(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

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.

the console. New algorithm:
* if stdin == keyboard, and parent of keyboard == adb, use ADB.
* else, must be a USB keyboard. Search backwards though the parents
until the USB controller is located. Determine its location in the PCI
domain, and which type of controller it is, and tell that controller that
it has the console input device. The USB code will then attach the first
USB keyboard as the console input device during autoconfiguration.
The iMac and Blue and White G3 consoles are fully functional now!

attach the first USB keyboard instance as the console keyboard.
Unfortunately, this must still be deferred to autoconfiguration time,
but there's not much we can do about that right now.
of the buffer you're copying from as the loop interator, not the length
of the buffer you're copying to. Also, rewrite print_single() with
pointer instead of array operators. Appears to correct some ADB-related
`hangs' during autoconfig.
necessary because some interrupt handlers may cause additional faults (e.g.
through R/M emulation) and thereby trash the previous fault state.
From Richard Earnshaw.
By code inspection I found 2 bugs in the ATAPI code, one may be the cause
of your problem: A counter is not reset when issuing the request_sense
command. This is c_skip, the counter used to track the offset in the data
buffer when a data tranfer needs multiple phases. The effect of this is that
the sense data transfered may be stored outside the sense buffer (sense buffer
+ some, potentially several KB, offset). This can only occur in PIO mode,
DMA is not affected.
This doesn't occur in "normal" use because when reading a data CD, either
the sense is issued for a non-data command (in which case c_skip stays to
0), or an error occured and no data has been transfered, and c_skip is still 0.
I can't see a case where a data READ/WRITE could cause a sense tranfer without
error.
The second problem is that b_resid can be set to a false value (resulting of
the sense tranfer and not the data transfer). Again this is not a problem with
usual data tranfers because both values ends up being 0 when no error occurs.
count is 0, wait for use count to drain before finishing the close.
This is necessary in order for multiple processes to safely share file
descriptor tables.
and _C_LABEL(syscall) in trap.c. In ELF they are the same. Change the label
in locore.s to be _C_LABEL(_syscall).
While I am there, move the register save and restoral code used in the
*sigcode trampolines into two macros and use them instead of copying 100
lines of assembly each time.
Now everything ELF works.
No flags will not work, because it will produce a kernel loaded at 0xf0000000.
This is because the bfd ELF pagesize (in elf32-sparc.c) is 0x10000. Since
we need to load at 0xf0004000, we use -n.

the current structure of our initialization code, it probably would have
