augustss 72afbf03cf Run power hooks in reverse installation order when powering down and
installation order when powering up.  This allows drivers in a hierarchy
to DTRT.

thorpej 956b3ca3b3 Track which process a CPU is running/has last run on by adding a
p_cpu member to struct proc.  Use this in certain places when
accessing scheduler state, etc.  For the single-processor case,
just initialize p_cpu in fork1() to avoid having to set it in the
low-level context switch code on platforms which will never have
multiprocessing.

While I'm here, comment a few places where there are known issues
for the SMP implementation.

thorpej a7d0570e67 First sweep at scheduler state cleanup. Collect MI scheduler
state into global and per-CPU scheduler state:

	- Global state: sched_qs (run queues), sched_whichqs (bitmap
	  of non-empty run queues), sched_slpque (sleep queues).
	  NOTE: These may collectively move into a struct schedstate
	  at some point in the future.

	- Per-CPU state, struct schedstate_percpu: spc_runtime
	  (time process on this CPU started running), spc_flags
	  (replaces struct proc's p_schedflags), and
	  spc_curpriority (usrpri of processes on this CPU).

	- Every platform must now supply a struct cpu_info and
	  a curcpu() macro.  Simplify existing cpu_info declarations
	  where appropriate.

	- All references to per-CPU scheduler state now made through
	  curcpu().  NOTE: this will likely be adjusted in the future
	  after further changes to struct proc are made.

Tested on i386 and Alpha.  Changes are mostly mechanical, but apologies
in advance if it doesn't compile on a particular platform.

preempt() primitive to do so.

sommerfeld cd14e5fa0c Add a fifth "divisor" argument to humanize_number; suitable values are
either 1024 or 1000.
Needed because frequencies use decimal rather than power-of-two SI
prefixes.

oster 919df6690a Add support for / on RAID. A bit of a gross hack, but sufficient for now.
Note that this doesn't help you much until the RAID autoconfig code
in sys/dev/raidframe/rf_netbsdkintf.c is turned on.

enami 65c138fea0 - Print a name of root device even if it is a network device.
- If RB_ASKNAME, only dumpdv holds the results asked interactively.
  Examie dumpspec only when !RB_ASKNAME.  This allows us to override
  dumps on none in kernel config file by booting kernel with RB_ASKNAME.
- Slightly rearrange code so that it more matches to comment.

enami 047cc5e94f Cleanup setroot() a bit:
- No longer necessary to use goto, just breaking the loop like other case
  is enough.
- Don't caliculate loop invariant every time.  Just reuse.

fvdl 65e677bd99 Add an exec hook mechanism, where kernel subsystem can register to
execute certain functions when a process does an exec(). Currently
uses a global list. Could possibly be done using a per-process list,
but this needs more thought.

augustss 94b815050e Add powerhooks, i.e., the ability to register a function that will be

thorpej d76e7b8c6d Don't pass a nam2blk around at all; just have setroot() and friends reference
dev_name2blk[] directly.  Addresses PR #7622 (ITOH Yasufumi), although
in a different way.

lukem 5e76cbddfb in humanize_number(), when printing a u_int64_t, use '%qu' (unsigned long long)

lukem 719cd63d24 Implement format_bytes(), which pretty prints a given u_int64_t into a
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)).

mrg 1a8c7604f4 initial import of the new virtual memory system, UVM, into -current.
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code.  i provided some help
getting swap and paging working, and other bug fixes/ideas.  chuck
silvers <chuq@chuq.com> also provided some other fixes.

this is the rest of the MI portion changes.

this will be KNF'd shortly.  :-)

case if a network interface is selected as the root device.
1997-06-16 00:25:05 +00:00
thorpej 91f7efbaf9 Fix crash dump device selection after the recent swap changes:
- If RB_ASKNAME, prompt for the dump device, defaulting to
  partition 'b' of the root device, if the root device is a disk.
- Else, if dumpspec is set to "none", do not configure a dump device.
- Else, if dumpspec is set by config(8), attempt to use that device.
- Else, dumpspec is wildcarded or unspecified; if the root device is
  a disk, select partition b.  (which was the previous default dump
  partition)

Note, dumps to a local disk now work even if root is on nfs.
