+.TH PANIC 9k
+.SH NAME
+archreset, exit, panic, ndnr \- abandon hope
+.SH SYNOPSIS
+.ta \w'\fLchar* 'u
+.B
+void	archreset(void)
+.br
+.B
+void	exit(int ispanic)
+.br
+.B
+void	ndnr(void)

+.SH DESCRIPTION
+.PP
+.I Archreset
+reboots the machine.
+.PP
+Depending on configuration settings, the platform-dependent
+.I exit
+might reboot the system.  If
+.I ispanic
+is set,
+.I panic
+is called.
+.PP
+.I Ndnr
+(no deposit, no return)
+disables all
+interrupt sources and halts the current processor.
+.PP
+.I Panic
+writes a message to the console and
+causes the system to give up the ghost.
+It disables interrupts, dumps the kernel stack,
+and halts the current processor;
+if more than one, others will gradually come to a halt.
+A subsequent
+.I panic
+on a different processor will halt that processor with
+.IR ndnr;
+a recursive
+.I panic
+will reboot the machine with
+.IR archreset.
+.PP
+The format
+.I fmt
+and associated arguments are the same as those for
+.IR print (9).
+.I Panic
+adds a prefix
+.L "panic: cpu\fIn\fP:"
+and a trailing newline.
+.SH "SEE ALSO"
+.IR panic (9)
+.SH BUGS
+Note the differences with
+.IR panic (9).

+.SH DESCRIPTION
+The kernel contains a buddy allocator to hand out large chunks of
+memory outside the kernel heap.  The buddy allocator does not
+assign virtual addresses. The map is populated by one or more calls to
+.IR physinit .
+.I Physalloc
+allocates a region of the given color with the given tag.  If the color
+is -1, then any memory color may be used, otherwise only memory
+of the given color will be allocated.  The
+.B tag
+is user-defined.  Calls to
+.I phystag
+map addresses in the allocation back to
+.BR tag .
+Allocated regions are freed with
+.IR physfree .
+Stats may be put in a buffer with
+.IR seprintstats ,
+which takes a pointer to a buffer and its end as
+.IR seprint .

+.SH DESCRIPTION
+These are kernel versions of the functions in
+.IR malloc (2).
+They allocate memory with Quickfit with an allocator
+from Kernighan & Ritchie.
+The allocation is currently fixed, but could call
+.IR physalloc (9k)
+in the future.
+All but
+.I smalloc
+(which calls
+.IR sleep (9))
+may safely be called by interrupt handlers.
+.PP
+.I Malloc
+returns a pointer to a block of at least
+.I size
+bytes, initialised to zero.
+The block is suitably aligned for storage of any type of object.
+The call
+.B malloc(0)
+returns a valid pointer rather than null.
+.I Mallocz
+is similar, but only clears the memory if
+.I clr
+is non-zero.
+.PP
+.I Smalloc
+returns a pointer to a block of
+.I size
+bytes, initialised to zero.
+If the memory is not immediately available,
+.I smalloc
+retries every 100 milliseconds until the memory is acquired.
+.PP
+.I Mallocalign
+allocates a block of at least 
+.I n
+bytes of memory respecting alignment contraints.
+If
+.I align
+is non-zero,
+the returned pointer is aligned to be equal to
+.I offset
+modulo
+.IR align .
+If
+.I span
+is non-zero,
+the
+.I n
+byte block allocated will not span a
+.IR span -byte
+boundary.
+.PP
+.I Realloc
+changes the size of the block pointed to by
+.I p
+to
+.I size
+bytes,
+if possible without moving the data,
+and returns a pointer to the block.
+The contents are unchanged up to the lesser of old and new sizes,
+and any new space allocated is initialised to zero.
+.I Realloc
+takes on special meanings when one or both arguments are zero:
+.TP
+.B "realloc(0,\ size)
+means
+.LR malloc(size) ;
+returns a pointer to the newly-allocated memory
+.TP
+.B "realloc(ptr,\ 0)
+means
+.LR free(ptr) ;
+returns null
+.TP
+.B "realloc(0,\ 0)
+no-op; returns null
+.PD
+.PP
+.I Calloc
+returns a pointer to a block of memory of at least
+.I "n*szelem"
+bytes, initialised to zero.
+New code should use
+.I mallocz
+instead.
+.PP
+The argument to
+.I free
+is a pointer to a block of memory allocated by one of the routines above, which
+is returned to the allocation pool, or a null pointer, which is ignored.
+.PP
+When a block is allocated, sometimes there is some extra unused space at the end.
+.I Msize
+grows the block to encompass this unused space and returns the new number
+of bytes that may be used.
+.PP
+The memory allocator does not maintain ``malloc tag'' and the ``realloc tag'',
+but the functions 
+.IR setmalloctag ,
+.IR getmalloctag ,
+.IR setrealloctag ,
+and
+.IR getrealloctag 
+are provided for compaibility with the
+.IR pool (2)
+library.
+.PP
+.I Mallocinit
+must be called before
+.I malloc
+is used.
+.I Mallocsummary
+prints a short summary of the allocator's state on the console.
