FreeBSD/mips port. The FreeBSD/mips port targets mips32, mips64,
mips32r2 and mips64r2 (and close relatives) processors. There presently is support for ADMtek ADM5120, A mips 4Kc in a malta board, the RB533 routerboard (based on IDT RC32434) and some preliminary support for sibtye/broadcom designs. Other hardware support will be forthcomcing. This port boots multiuser under gxemul emulating the malta board and also bootstraps on the hardware whose support is forthcoming... Oleksandr Tymoshenko, Wojciech Koszek, Warner Losh, Olivier Houchard, Randall Stewert and others that have contributed to the mips2 and/or mips2-jnpr perforce branches. Juniper contirbuted a generic mips port late in the life cycle of the misp2 branch. Warner Losh merged the mips2 and Juniper code bases, and others list above have worked for the past several months to get to multiuser. In addition, the mips2 work owe a debt to the trail blazing efforts of the original mips branch in perforce done by Juli Mallett.

* __mcount is like [.]mcount except that doesn't require its caller to set

* cases. This would make -pg in combination with -fomit-frame-pointer
|
||||
* useful. gcc has a configuration variable PROFILE_BEFORE_PROLOGUE to
|
||||
* allow profiling before setting up the frame pointer, but this is
|
||||
* inadequate for good handling of special cases, e.g., -fpic works best
|
||||
* with profiling after the prologue.
|
||||
*
|
||||
* [.]mexitcount is a new function to support non-statistical profiling if an
|
||||
* accurate clock is available. For C sources, calls to it are generated
|
||||
* by the FreeBSD extension `-mprofiler-epilogue' to gcc. It is best to
|
||||
* call [.]mexitcount at the end of a function like the MEXITCOUNT macro does,

* but gcc currently generates calls to it at the start of the epilogue to
|
||||
* avoid problems with -fpic.
|
||||
*
|
||||
* [.]mcount and __mcount may clobber the call-used registers and %ef.
|
||||
* [.]mexitcount may clobber %ecx and %ef.
|
||||
*
|
||||
* Cross-jumping makes non-statistical profiling timing more complicated.
|
||||
* It is handled in many cases by calling [.]mexitcount before jumping. It
|
||||
* is handled for conditional jumps using CROSSJUMP() and CROSSJUMP_LABEL().
|
||||
* It is handled for some fault-handling jumps by not sharing the exit
|
||||
* routine.
|

*
|
||||
* ALTENTRY() must be before a corresponding ENTRY() so that it can jump to
|
||||
* the main entry point. Note that alt entries are counted twice. They
|
||||
* have to be counted as ordinary entries for gprof to get the call times
|

* right for the ordinary entries.
|

*
|
||||
* High local labels are used in macros to avoid clashes with local labels
|
||||
* in functions.
|
||||
*
|
||||
* Ordinary `ret' is used instead of a macro `RET' because there are a lot
|
||||
* of `ret's. 0xc3 is the opcode for `ret' (`#define ret ... ret' can't
|
||||
* be used because this file is sometimes preprocessed in traditional mode).
|
||||
* `ret' clobbers eflags but this doesn't matter.

* icache_sync_all Synchronize I-cache
|
||||
*
|
||||
* icache_sync_range Synchronize I-cache range
|
||||
*
|
||||
* icache_sync_range_index (index ops)
|
||||
*
|
||||
* --- Primary data cache (mandatory):
|
||||
*
|
||||
* pdcache_wbinv_all Write-back Invalidate primary D-cache
|
||||
*
|
||||
* pdcache_wbinv_range Write-back Invalidate primary D-cache range
|
||||
*
|
||||
* pdcache_wbinv_range_index (index ops)
|
||||
*
|
||||
* pdcache_inv_range Invalidate primary D-cache range
|
||||
*
|
||||
* pdcache_wb_range Write-back primary D-cache range
|
||||
*
|
||||
* --- Secondary data cache (optional):
|
||||
*
|
||||
* sdcache_wbinv_all Write-back Invalidate secondary D-cache
|
||||
*
|
||||
* sdcache_wbinv_range Write-back Invalidate secondary D-cache range
|
||||
*
|
||||
* sdcache_wbinv_range_index (index ops)
|
||||
*
|
||||
* sdcache_inv_range Invalidate secondary D-cache range
|
||||
*
|
||||
* sdcache_wb_range Write-back secondary D-cache range
|
||||
*
|
||||
* There are some rules that must be followed:
|
||||
*
|
||||
* I-cache Synch (all or range):
|
||||
* The goal is to synchronize the instruction stream,
|
||||
* so you may need to write-back dirty data cache
|
||||
* blocks first. If a range is requested, and you
|
||||
* can't synchronize just a range, you have to hit
|
||||
* the whole thing.
|
||||
*
|
||||
* D-cache Write-back Invalidate range:
|
||||
* If you can't WB-Inv a range, you must WB-Inv the
|
||||
* entire D-cache.
|
||||
*
|
||||
* D-cache Invalidate:
|
||||
* If you can't Inv the D-cache without doing a
|
||||
* Write-back, YOU MUST PANIC. This is to catch
|
||||
* errors in calling code. Callers must be aware
|
||||
* of this scenario, and must handle it appropriately
|
||||
* (consider the bus_dma(9) operations).
|
||||
*
|
||||
* D-cache Write-back:
|
||||
* If you can't Write-back without doing an invalidate,
|
||||
* that's fine. Then treat this as a WB-Inv. Skipping
|
||||
* the invalidate is merely an optimization.
|
||||
*
|
||||
* All operations:
|
||||
* Valid virtual addresses must be passed to the
|
||||
* cache operation.
|
||||
*
|
||||
* Finally, these primitives are grouped together in reasonable
|
||||
* ways. For all operations described here, first the primary
|
||||
* cache is frobbed, then the secondary cache frobbed, if the
|
||||
* operation for the secondary cache exists.

/*---------------------------------------------------------------------------

* QUEUE MANAGEMENT DOCUMENTATION
|
||||
*/
|
||||
|
||||
/*
|
||||
--------
|
||||
Q_INIT()
|
||||
--------
|
||||
|
||||
void q_init(void)
|
||||
|
||||
Initialize the queue management system for the microkernel.
|
||||
This initializes the debugging flags and sets up accounting.
|
||||
|
||||
---------
|
||||
Q_ALLOC()
|
||||
---------
|
||||
|
||||
queue_t *q_alloc()
|
||||
|
||||
Allocates a queue from kernel memory, and initializes it for you.
|
||||
|
||||
The default initialization provides a queue that is unbounded.
|
||||
|
||||
If you want to be bounded with special features, use q_control
|
||||
after initialization.
|
||||
|
||||
q_alloc() returns NULL in the face of peril or low memory.
|
||||
|
||||
--------
|
||||
Q_FREE()
|
||||
--------
|
||||
|
||||
void *q_free(queue_t *queue_pointer)
|
||||
|
||||
Returns a queue to kernel memory, and frees the queue contents
|
||||
for you using free() and complains (with a traceback) that you
|
||||
tried to kill of a non-empty queue.
|
||||
|
||||
If any threads are waiting on the queue, wake them up.
|
||||
|
||||
-----------
|
||||
Q_CONTROL()
|
||||
-----------
|
||||
void q_control(queue_t *queue_pointer, queue_size_t max_queue_size);
|
||||
|
||||
For now, allows you to limit queue growth.
|
||||
|
||||
----------------
|
||||
Q_DEQUEUE_WAIT() ** MAY CAUSE THREAD TO BLOCK/CANNOT BE CALLED FROM ISRs **
|
||||
----------------
|
||||
|
||||
void *q_dequeue_wait(queue_t *queue_pointer, wakeup_mask_t *mask)
|
||||
|
||||
Removes and returns a pointer to the next message in the specified
|
||||
queue. If the queue is empty, the calling thread goes to sleep
|
||||
until something is queued to the queue. If this call returns NULL,
|
||||
then an extraordinary event requires this thread's attention--
|
||||
check errno in this case.
|
||||
|
||||
---------
|
||||
Q_DEQUEUE ** CAN BE CALLED FROM ISRs **
|
||||
---------
|
||||
|
||||
void *q_dequeue(queue_t *queue_pointer)
|
||||
|
||||
Just like q_dequeue_wait(), but instead of blocking, return NULL.
|
||||
|
||||
-----------
|
||||
Q_ENQUEUE() ** CAN BE CALLED FROM ISRs **
|
||||
-----------
|
||||
|
||||
boolean q_enqueue(queue_t *queue_pointer, void *element_pointer)
|
||||
|
||||
Add the element to the end of the named queue. If the add fails
|
||||
because a limit has been reached, return TRUE. Otherwise return
|
||||
FALSE if everything went OK.
|
||||
|
||||
----------
|
||||
Q_URGENT()
|
||||
----------
|
||||
|
||||
boolean q_urgent(queue_t *queue_pointer, void *element_pointer)
|
||||
|
||||
Same as q_enqueue(), except this element will be placed at the top
|
||||
of the queue, and will be picked off at the next q_dequeue_wait()
|
||||
operation.
|
||||
|
||||
--------
|
||||
Q_PEEK() ** CAN BE CALLED FROM ISRs **
|
||||
--------
|
||||
|
||||
void *q_peek(queue_t *queue_pointer)
|
||||
|
||||
Returns a pointer to the top element of the queue without actually
|
||||
dequeuing it. Returns NULL of the queue is empty.
|
||||
|
||||
This routine will never block.
|
||||
|
||||
----------
|
||||
Q_DELETE()
|
||||
----------
|
||||
|
||||
void q_delete(queue_t *queue_pointer, void *element_pointer)
|
||||
|
||||
Delete the element_pointer from the queue, if it exists. This
|
||||
isn't speedy, and isn't meant for tasks requiring performance.
|
||||
It's primary use is to pull something off the queue when you know
|
||||
in the common case that it's gonna be at or near the top of the
|
||||
list. (I.e. waking a thread from a wake list when extraordinary
|
||||
conditions exist, and you have to pluck it from the middle of the
|
||||
list.)
|
||||
|
||||
This routine does not block or return anything.
|
||||
|
||||
--------
|
||||
Q_SIZE()
|
||||
--------
|
||||
|
||||
queue_size_t q_size(queue_t *queue_pointer)
|
||||
|
||||
Returns the number of elements in the queue.
|
||||
|
||||
------------
|
||||
Q_MAX_SIZE()
|
||||
------------
|
||||
|
||||
queue_size_t q_max_size(queue_t *queue_pointer);
|
||||
|
||||
Returns the maximum size of this queue, or 0 if this queue is
|
||||
unbounded.
