Block io priorities
|
||||
===================
|
||||
|
||||
|
||||
Intro
|
||||
-----
|
||||
|
||||
With the introduction of cfq v3 (aka cfq-ts or time sliced cfq), basic io
|
||||
priorities is supported for reads on files. This enables users to io nice
|
||||
processes or process groups, similar to what has been possible to cpu
|
||||
scheduling for ages. This document mainly details the current possibilites
|
||||
with cfq, other io schedulers do not support io priorities so far.
|
||||
|
||||
Scheduling classes
|
||||
------------------
|
||||
|
||||
CFQ implements three generic scheduling classes that determine how io is
|
||||
served for a process.
|
||||
|
||||
IOPRIO_CLASS_RT: This is the realtime io class. This scheduling class is given
|
||||
higher priority than any other in the system, processes from this class are
|
||||
given first access to the disk every time. Thus it needs to be used with some
|
||||
care, one io RT process can starve the entire system. Within the RT class,
|
||||
there are 8 levels of class data that determine exactly how much time this
|
||||
process needs the disk for on each service. In the future this might change
|
||||
to be more directly mappable to performance, by passing in a wanted data
|
||||
rate instead.
|
||||
|
||||
IOPRIO_CLASS_BE: This is the best-effort scheduling class, which is the default
|
||||
for any process that hasn't set a specific io priority. The class data
|
||||
determines how much io bandwidth the process will get, it's directly mappable
|
||||
to the cpu nice levels just more coarsely implemented. 0 is the highest
|
||||
BE prio level, 7 is the lowest. The mapping between cpu nice level and io
|
||||
nice level is determined as: io_nice = (cpu_nice + 20) / 5.
|
||||
|
||||
IOPRIO_CLASS_IDLE: This is the idle scheduling class, processes running at this
|
||||
level only get io time when no one else needs the disk. The idle class has no
|
||||
class data, since it doesn't really apply here.

||||
See below for a sample ionice tool. Usage:
|
||||
|
||||
# ionice -c<class> -n<level> -p<pid>
|
||||
|
||||
If pid isn't given, the current process is assumed. IO priority settings
|
||||
are inherited on fork, so you can use ionice to start the process at a given
|
||||
level:
|
||||
|
||||
# ionice -c2 -n0 /bin/ls
|
||||
|
||||
will run ls at the best-effort scheduling class at the highest priority.
|
||||
For a running process, you can give the pid instead:
|
||||
|
||||
# ionice -c1 -n2 -p100
|
||||
|
||||
will change pid 100 to run at the realtime scheduling class, at priority 2.

A. Compiler command:
|
||||
This driver provides kernel support for Davicom DM9102(A)/DM9132/DM9801 ethernet cards ( CNET
|
||||
10/100 ethernet cards uses Davicom chipset too, so this driver supports CNET cards too ).If you
|
||||
didn't compile this driver as a module, it will automatically load itself on boot and print a
|
||||
line similar to :
|
||||
|
||||
A-1: For normal single or multiple processor kernel
|
||||
"gcc -DMODULE -D__KERNEL__ -I/usr/src/linux/net/inet -Wall
|
||||
-Wstrict-prototypes -O6 -c dmfe.c"
|
||||
dmfe: Davicom DM9xxx net driver, version 1.36.4 (2002-01-17)
|
||||
|
||||
A-2: For single or multiple processor with kernel module version function
|
||||
"gcc -DMODULE -DMODVERSIONS -D__KERNEL__ -I/usr/src/linux/net/inet
|
||||
-Wall -Wstrict-prototypes -O6 -c dmfe.c"
|
||||
If you compiled this driver as a module, you have to load it on boot.You can load it with command :
|
||||
|
||||
insmod dmfe
|
||||
|
||||
This way it will autodetect the device mode.This is the suggested way to load the module.Or you can pass
|
||||
a mode= setting to module while loading, like :
|
||||
|
||||
insmod dmfe mode=0 # Force 10M Half Duplex
|
||||
insmod dmfe mode=1 # Force 100M Half Duplex
|
||||
insmod dmfe mode=4 # Force 10M Full Duplex
|
||||
insmod dmfe mode=5 # Force 100M Full Duplex
|
||||
|
||||
Next you should configure your network interface with a command similar to :
|
||||
|
||||
ifconfig eth0 172.22.3.18
|
||||
^^^^^^^^^^^
|
||||
Your IP Adress
|
||||
|
||||
Then you may have to modify the default routing table with command :
|
||||
|
||||
route add default eth0
|
||||
|
||||
|
||||
B. The following steps teach you how to activate a DM9102 board:
|
||||
|
||||
1. Used the upper compiler command to compile dmfe.c
|
||||
|
||||
2. Insert dmfe module into kernel
|
||||
"insmod dmfe" ;;Auto Detection Mode (Suggest)
|
||||
"insmod dmfe mode=0" ;;Force 10M Half Duplex
|
||||
"insmod dmfe mode=1" ;;Force 100M Half Duplex
|
||||
"insmod dmfe mode=4" ;;Force 10M Full Duplex
|
||||
"insmod dmfe mode=5" ;;Force 100M Full Duplex
|
||||
|
||||
3. Config a dm9102 network interface
|
||||
"ifconfig eth0 172.22.3.18"
|
||||
^^^^^^^^^^^ Your IP address
|
||||
|
||||
4. Activate the IP routing table. For some distributions, it is not
|
||||
necessary. You can type "route" to check.
|
||||
|
||||
"route add default eth0"
|
||||
Now your ethernet card should be up and running.
|
||||
|
||||
|
||||
5. Well done. Your DM9102 adapter is now activated.

||||

LC-trie implementation notes.
|
||||
|
||||
Node types
|
||||
----------
|
||||
leaf
|
||||
An end node with data. This has a copy of the relevant key, along
|
||||
with 'hlist' with routing table entries sorted by prefix length.
|
||||
See struct leaf and struct leaf_info.
|
||||
|
||||
trie node or tnode
|
||||
An internal node, holding an array of child (leaf or tnode) pointers,
|
||||
indexed through a subset of the key. See Level Compression.
|
||||
|
||||
A few concepts explained
|
||||
------------------------
|
||||
Bits (tnode)
|
||||
The number of bits in the key segment used for indexing into the
|
||||
child array - the "child index". See Level Compression.
|
||||
|
||||
Pos (tnode)
|
||||
The position (in the key) of the key segment used for indexing into
|
||||
the child array. See Path Compression.
|
||||
|
||||
Path Compression / skipped bits
|
||||
Any given tnode is linked to from the child array of its parent, using
|
||||
a segment of the key specified by the parent's "pos" and "bits"
|
||||
In certain cases, this tnode's own "pos" will not be immediately
|
||||
adjacent to the parent (pos+bits), but there will be some bits
|
||||
in the key skipped over because they represent a single path with no
|
||||
deviations. These "skipped bits" constitute Path Compression.
|
||||
Note that the search algorithm will simply skip over these bits when
|
||||
searching, making it necessary to save the keys in the leaves to
|
||||
verify that they actually do match the key we are searching for.
|
||||
|
||||
Level Compression / child arrays
|
||||
the trie is kept level balanced moving, under certain conditions, the
|
||||
children of a full child (see "full_children") up one level, so that
|
||||
instead of a pure binary tree, each internal node ("tnode") may
|
||||
contain an arbitrarily large array of links to several children.
|
||||
Conversely, a tnode with a mostly empty child array (see empty_children)
|
||||
may be "halved", having some of its children moved downwards one level,
|
||||
in order to avoid ever-increasing child arrays.
|
||||
|
||||
empty_children
|
||||
the number of positions in the child array of a given tnode that are
|
||||
NULL.
|
||||
|
||||
full_children
|
||||
the number of children of a given tnode that aren't path compressed.
|
||||
(in other words, they aren't NULL or leaves and their "pos" is equal
|
||||
to this tnode's "pos"+"bits").
|
||||
|
||||
(The word "full" here is used more in the sense of "complete" than
|
||||
as the opposite of "empty", which might be a tad confusing.)
|
||||
|
||||
Comments
|
||||
---------
|
||||
|
||||
We have tried to keep the structure of the code as close to fib_hash as
|
||||
possible to allow verification and help up reviewing.
|
||||
|
||||
fib_find_node()
|
||||
A good start for understanding this code. This function implements a
|
||||
straightforward trie lookup.
|
||||
|
||||
fib_insert_node()
|
||||
Inserts a new leaf node in the trie. This is bit more complicated than
|
||||
fib_find_node(). Inserting a new node means we might have to run the
|
||||
level compression algorithm on part of the trie.
|
||||
|
||||
trie_leaf_remove()
|
||||
Looks up a key, deletes it and runs the level compression algorithm.
|
||||
|
||||
trie_rebalance()
|
||||
The key function for the dynamic trie after any change in the trie
|
||||
it is run to optimize and reorganize. Tt will walk the trie upwards
|
||||
towards the root from a given tnode, doing a resize() at each step
|
||||
to implement level compression.
|
||||
|
||||
resize()
|
||||
Analyzes a tnode and optimizes the child array size by either inflating
|
||||
or shrinking it repeatedly until it fullfills the criteria for optimal
|
||||
level compression. This part follows the original paper pretty closely
|
||||
and there may be some room for experimentation here.
|
||||
|
||||
inflate()
|
||||
Doubles the size of the child array within a tnode. Used by resize().
|
||||
|
||||
halve()
|
||||
Halves the size of the child array within a tnode - the inverse of
|
||||
inflate(). Used by resize();
|
||||
|
||||
fn_trie_insert(), fn_trie_delete(), fn_trie_select_default()
|
||||
The route manipulation functions. Should conform pretty closely to the
|
||||
corresponding functions in fib_hash.
|
||||
|
||||
fn_trie_flush()
|
||||
This walks the full trie (using nextleaf()) and searches for empty
|
||||
leaves which have to be removed.
|
||||
|
||||
fn_trie_dump()
|
||||
Dumps the routing table ordered by prefix length. This is somewhat
|
||||
slower than the corresponding fib_hash function, as we have to walk the
|
||||
entire trie for each prefix length. In comparison, fib_hash is organized
|
||||
as one "zone"/hash per prefix length.
|
||||
|
||||
Locking
|
||||
-------
|
||||
|
||||
fib_lock is used for an RW-lock in the same way that this is done in fib_hash.
|
||||
However, the functions are somewhat separated for other possible locking
|
||||
scenarios. It might conceivably be possible to run trie_rebalance via RCU
|
||||
to avoid read_lock in the fn_trie_lookup() function.
|
||||
|
||||
Main lookup mechanism
|
||||
---------------------
|
||||
fn_trie_lookup() is the main lookup function.
|
||||
|
||||
The lookup is in its simplest form just like fib_find_node(). We descend the
|
||||
trie, key segment by key segment, until we find a leaf. check_leaf() does
|
||||
the fib_semantic_match in the leaf's sorted prefix hlist.
|
||||
|
||||
If we find a match, we are done.
|
||||
|
||||
If we don't find a match, we enter prefix matching mode. The prefix length,
|
||||
starting out at the same as the key length, is reduced one step at a time,
|
||||
and we backtrack upwards through the trie trying to find a longest matching
|
||||
prefix. The goal is always to reach a leaf and get a positive result from the
|
||||
fib_semantic_match mechanism.
|
||||
|
||||
Inside each tnode, the search for longest matching prefix consists of searching
|
||||
through the child array, chopping off (zeroing) the least significant "1" of
|
||||
the child index until we find a match or the child index consists of nothing but
|
||||
zeros.
|
||||
|
||||
At this point we backtrack (t->stats.backtrack++) up the trie, continuing to
|
||||
chop off part of the key in order to find the longest matching prefix.
|
||||
|
||||
At this point we will repeatedly descend subtries to look for a match, and there
|
||||
are some optimizations available that can provide us with "shortcuts" to avoid
|
||||
descending into dead ends. Look for "HL_OPTIMIZE" sections in the code.
|
||||
|
||||
To alleviate any doubts about the correctness of the route selection process,
|
||||
a new netlink operation has been added. Look for NETLINK_FIB_LOOKUP, which
|
||||
gives userland access to fib_lookup().

Matching of PCMCIA devices to drivers is done using one or more of the
|
||||
following criteria:
|
||||
|
||||
- manufactor ID
|
||||
- card ID
|
||||
- product ID strings _and_ hashes of these strings
|
||||
- function ID
|
||||
- device function (actual and pseudo)
|
||||
|
||||
You should use the helpers in include/pcmcia/device_id.h for generating the
|
||||
struct pcmcia_device_id[] entries which match devices to drivers.
|
||||
|
||||
If you want to match product ID strings, you also need to pass the crc32
|
||||
hashes of the string to the macro, e.g. if you want to match the product ID
|
||||
string 1, you need to use
|
||||
|
||||
PCMCIA_DEVICE_PROD_ID1("some_string", 0x(hash_of_some_string)),
|
||||
|
||||
If the hash is incorrect, the kernel will inform you about this in "dmesg"
|
||||
upon module initialization, and tell you of the correct hash.
|
||||
|
||||
You can determine the hash of the product ID strings by catting the file
|
||||
"modalias" in the sysfs directory of the PCMCIA device. It generates a string
|
||||
in the following form:

string 2 and so on.

Alternatively, you can use this small tool to determine the crc32 hash.

simply pass the string you want to evaluate as argument to this program,

This file details changes in 2.6 which affect PCMCIA card driver authors:
|
||||
|
||||
* in-kernel device<->driver matching
|
||||
PCMCIA devices and their correct drivers can now be matched in
|
||||
kernelspace. See 'devicetable.txt' for details.
|
||||
|
||||
* Device model integration (as of 2.6.11)
|
||||
A struct pcmcia_device is registered with the device model core,
|
||||
and can be used (e.g. for SET_NETDEV_DEV) by using
|
||||
handle_to_dev(client_handle_t * handle).
|
||||
|
||||
* Convert internal I/O port addresses to unsigned long (as of 2.6.11)
|
||||
ioaddr_t should be replaced by kio_addr_t in PCMCIA card drivers.
|
||||
|
||||
* irq_mask and irq_list parameters (as of 2.6.11)
|
||||
The irq_mask and irq_list parameters should no longer be used in
|
||||
PCMCIA card drivers. Instead, it is the job of the PCMCIA core to
|
||||
determine which IRQ should be used. Therefore, link->irq.IRQInfo2
|
||||
is ignored.
|
||||
|
||||
* client->PendingEvents is gone (as of 2.6.11)
|
||||
client->PendingEvents is no longer available.
|
||||
|
||||
* client->Attributes are gone (as of 2.6.11)
|
||||
client->Attributes is unused, therefore it is removed from all
|
||||
PCMCIA card drivers
|
||||
|
||||
* core functions no longer available (as of 2.6.11)
|
||||
The following functions have been removed from the kernel source
|
||||
because they are unused by all in-kernel drivers, and no external
|
||||
driver was reported to rely on them:
|
||||
pcmcia_get_first_region()
|
||||
pcmcia_get_next_region()
|
||||
pcmcia_modify_window()
|
||||
pcmcia_set_event_mask()
|
||||
pcmcia_get_first_window()
|
||||
pcmcia_get_next_window()
|
||||
|
||||
* device list iteration upon module removal (as of 2.6.10)
|
||||
It is no longer necessary to iterate on the driver's internal
|
||||
client list and call the ->detach() function upon module removal.
|
||||
|
||||
* Resource management. (as of 2.6.8)
|
||||
Although the PCMCIA subsystem will allocate resources for cards,
|
||||
it no longer marks these resources busy. This means that driver
|
||||
authors are now responsible for claiming your resources as per
|
||||
other drivers in Linux. You should use request_region() to mark
|
||||
your IO regions in-use, and request_mem_region() to mark your
|
||||
memory regions in-use. The name argument should be a pointer to
|
||||
your driver name. Eg, for pcnet_cs, name should point to the
|
||||
string "pcnet_cs".

Video4Linux provides the following sets of device files. These live on the
|
||||
character device formerly known as "/dev/bttv". /dev/bttv should be a
|
||||
symlink to /dev/video0 for most people.

Video4Linux programs open and scan the devices to find what they are looking
|

for. Capability queries define what each interface supports. The

described API is only defined for video capture cards. The relevant subset
|

applies to radio cards. Teletext interfaces talk the existing VTX API.

<H3>Capability Query Ioctl</H3>

The <B>VIDIOCGCAP</B> ioctl call is used to obtain the capability
|

information for a video device. The <b>struct video_capability</b> object
|

</TABLE>
|
||||
<P>
|
||||
The minimum and maximum sizes listed for a capture device do not imply all
|
||||
that all height/width ratios or sizes within the range are possible. A
|
||||
request to set a size will be honoured by the largest available capture
|
||||
size whose capture is no large than the requested rectangle in either
|
||||
direction. For example the quickcam has 3 fixed settings.
|
||||
<P>
|
||||
<H3>Frame Buffer</H3>
|
||||
Capture cards that drop data directly onto the frame buffer must be told the
|
||||
base address of the frame buffer, its size and organisation. This is a
|
||||
privileged ioctl and one that eventually X itself should set.
|
||||
<P>
|
||||
The <b>VIDIOCSFBUF</b> ioctl sets the frame buffer parameters for a capture
|
||||
card. If the card does not do direct writes to the frame buffer then this
|
||||
ioctl will be unsupported. The <b>VIDIOCGFBUF</b> ioctl returns the
|
||||
currently used parameters. The structure used in both cases is a
|
||||
<b>struct video_buffer</b>.

Note that these values reflect the physical layout of the frame buffer.
|
||||
The visible area may be smaller. In fact under XFree86 this is commonly the
|
||||
case. XFree86 DGA can provide the parameters required to set up this ioctl.
|
||||
Setting the base address to NULL indicates there is no physical frame buffer
|
||||
access.
|

<P>
|
||||
<H3>Capture Windows</H3>
|
||||
The capture area is described by a <b>struct video_window</b>. This defines
|
||||
a capture area and the clipping information if relevant. The
|
||||
<b>VIDIOCGWIN</b> ioctl recovers the current settings and the
|
||||
<b>VIDIOCSWIN</b> sets new values. A successful call to <b>VIDIOCSWIN</b>
|
||||
indicates that a suitable set of parameters have been chosen. They do not
|
||||
indicate that exactly what was requested was granted. The program should
|
||||
call <b>VIDIOCGWIN</b> to check if the nearest match was suitable. The
|
||||
<b>struct video_window</b> contains the following fields.

Merely setting the window does not enable capturing. Overlay capturing
|

(i.e. PCI-PCI transfer to the frame buffer of the video card)
|

is activated by passing the <b>VIDIOCCAPTURE</b> ioctl a value of 1, and
|

disabled by passing it a value of 0.

<P>
|

Some capture devices can capture a subfield of the image they actually see.
|

This is indicated when VIDEO_TYPE_SUBCAPTURE is defined.

<H3>Video Sources</H3>

Each video4linux video or audio device captures from one or more

source <b>channels</b>. Each channel can be queries with the
|

<b>VDIOCGCHAN</b> ioctl call. Before invoking this function the caller
|
||||
must set the channel field to the channel that is being queried. On return
|
||||
the <b>struct video_channel</b> is filled in with information about the
|
||||
nature of the channel itself.
|

<P>
|
||||
The <b>VIDIOCSCHAN</b> ioctl takes an integer argument and switches the
|
||||
capture to this input. It is not defined whether parameters such as colour
|
||||
settings or tuning are maintained across a channel switch. The caller should

maintain settings as desired for each channel. (This is reasonable as

different video inputs may have different properties).

<H3>Reading Images</H3>
|
||||
Each call to the <b>read</b> syscall returns the next available image
|
||||
from the device. It is up to the caller to set format and size (using
|
||||
the VIDIOCSPICT and VIDIOCSWIN ioctls) and then to pass a suitable
|
||||
size buffer and length to the function. Not all devices will support
|
||||
read operations.
|
||||
<P>
|
||||
A second way to handle image capture is via the mmap interface if supported.
|
||||
To use the mmap interface a user first sets the desired image size and depth
|
||||
properties. Next the VIDIOCGMBUF ioctl is issued. This reports the size
|
||||
of buffer to mmap and the offset within the buffer for each frame. The
|
||||
number of frames supported is device dependent and may only be one.
|
||||
<P>
|
||||
The video_mbuf structure contains the following fields
|
||||
<P>
|
||||
<TABLE>
|
||||
<TR><TD><b>size</b><TD>The number of bytes to map</TD>
|
||||
<TR><TD><b>frames</b><TD>The number of frames</TD>
|
||||
<TR><TD><b>offsets</b><TD>The offset of each frame</TD>
|
||||
</TABLE>
|
||||
<P>
|
||||
Once the mmap has been made the VIDIOCMCAPTURE ioctl starts the
|
||||
capture to a frame using the format and image size specified in the
|
||||
video_mmap (which should match or be below the initial query size).
|
||||
When the VIDIOCMCAPTURE ioctl returns the frame is <em>not</em>
|
||||
captured yet, the driver just instructed the hardware to start the
|
||||
capture. The application has to use the VIDIOCSYNC ioctl to wait
|
||||
until the capture of a frame is finished. VIDIOCSYNC takes the frame
|
||||
number you want to wait for as argument.
|
||||
<p>
|
||||
It is allowed to call VIDIOCMCAPTURE multiple times (with different
|
||||
frame numbers in video_mmap->frame of course) and thus have multiple
|
||||
outstanding capture requests. A simple way do to double-buffering
|
||||
using this feature looks like this:
|
||||
<pre>
|
||||
/* setup everything */
|
||||
VIDIOCMCAPTURE(0)
|
||||
while (whatever) {
|
||||
VIDIOCMCAPTURE(1)
|
||||
VIDIOCSYNC(0)
|
||||
/* process frame 0 while the hardware captures frame 1 */
|
||||
VIDIOCMCAPTURE(0)
|
||||
VIDIOCSYNC(1)
|
||||
/* process frame 1 while the hardware captures frame 0 */
|
||||
}
|
||||
</pre>
|
||||
Note that you are <em>not</em> limited to only two frames. The API
|
||||
allows up to 32 frames, the VIDIOCGMBUF ioctl returns the number of
|
||||
frames the driver granted. Thus it is possible to build deeper queues
|
||||
to avoid loosing frames on load peaks.
|
||||
<p>
|
||||
While capturing to memory the driver will make a "best effort" attempt
|
||||
to capture to screen as well if requested. This normally means all
|
||||
frames that "miss" memory mapped capture will go to the display.
|
||||
<P>
|
||||
A final ioctl exists to allow a device to obtain related devices if a
|
||||
driver has multiple components (for example video0 may not be associated
|
||||
with vbi0 which would cause an intercast display program to make a bad
|
||||
mistake). The VIDIOCGUNIT ioctl reports the unit numbers of the associated
|
||||
devices if any exist. The video_unit structure has the following fields.

||||

and generates a two-part u32 product in HIGH_PROD and
|
||||
LOW_PROD.
|
||||
|
||||
2) __umulsidi3(a,b) multiplies two u32 integers A and B,
|
||||
and returns a u64 product. This is just a variant of umul_ppmm.
|
||||
|
||||
3) udiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
|
||||
denominator) divides a two-word unsigned integer, composed by the
|
||||
integers HIGH_NUMERATOR and LOW_NUMERATOR, by DENOMINATOR and
|
||||
places the quotient in QUOTIENT and the remainder in REMAINDER.
|
||||
HIGH_NUMERATOR must be less than DENOMINATOR for correct operation.
|
||||
If, in addition, the most significant bit of DENOMINATOR must be 1,
|
||||
then the pre-processor symbol UDIV_NEEDS_NORMALIZATION is defined to 1.
|
||||
|
||||
4) sdiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
|
||||
denominator). Like udiv_qrnnd but the numbers are signed. The
|
||||
quotient is rounded towards 0.
|
||||
|
||||
5) count_leading_zeros(count, x) counts the number of zero-bits from
|
||||
the msb to the first non-zero bit. This is the number of steps X
|
||||
needs to be shifted left to set the msb. Undefined for X == 0.
|
||||
|
||||
6) add_ssaaaa(high_sum, low_sum, high_addend_1, low_addend_1,
|
||||
high_addend_2, low_addend_2) adds two two-word unsigned integers,
|
||||
composed by HIGH_ADDEND_1 and LOW_ADDEND_1, and HIGH_ADDEND_2 and
|
||||
LOW_ADDEND_2 respectively. The result is placed in HIGH_SUM and
|
||||
LOW_SUM. Overflow (i.e. carry out) is not stored anywhere, and is
|
||||
lost.
|
||||
|
||||
7) sub_ddmmss(high_difference, low_difference, high_minuend,
|
||||
low_minuend, high_subtrahend, low_subtrahend) subtracts two
|
||||
two-word unsigned integers, composed by HIGH_MINUEND_1 and
|
||||
LOW_MINUEND_1, and HIGH_SUBTRAHEND_2 and LOW_SUBTRAHEND_2
|
||||
respectively. The result is placed in HIGH_DIFFERENCE and
|
||||
LOW_DIFFERENCE. Overflow (i.e. carry out) is not stored anywhere,
|
||||
and is lost.
|
||||
|
||||
If any of these macros are left undefined for a particular CPU,
|
||||
C macros are used. */
