+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.
+
+Tools
+-----
+
+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.

+ 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:
+pcmcia:m0149cC1ABf06pfn00fn00pa725B842DpbF1EFEE84pc0877B627pd00000000
+
+The hex value after "pa" is the hash of product ID string 1, after "pb" for
+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,
+e.g.
+$ ./crc32hash "Dual Speed"
+
+-------------------------------------------------------------------------
+/* crc32hash.c - derived from linux/lib/crc32.c, GNU GPL v2 */
+#include <string.h>
+#include <stdio.h>
+#include <ctype.h>
+#include <stdlib.h>

+ while (len--) {
+ crc ^= *p++;

+ crc = (crc >> 1) ^ ((crc & 1) ? 0xedb88320 : 0);
+ }
+ return crc;
+}

+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".

-<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

-<P>
-<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.
-<P>
-<TABLE>
-<TR><TD><b>video</b><TD>Video capture device</TD>
-<TR><TD><b>vbi</b><TD>VBI capture device</TD>
-<TR><TD><b>radio</b><TD>Radio device</TD>
-<TR><TD><b>audio</b><TD>Audio mixer</TD>
-<TR><TD><b>teletext</b><TD>Teletext device</TD>
-</TABLE>
-<P>
-<H3>RDS Datastreams</H3>
-For radio devices that support it, it is possible to receive Radio Data
-System (RDS) data by means of a read() on the device. The data is packed in
-groups of three, as follows:
-<TABLE>
-<TR><TD>First Octet</TD><TD>Least Significant Byte of RDS Block</TD></TR>
-<TR><TD>Second Octet</TD><TD>Most Significant Byte of RDS Block
-<TR><TD>Third Octet</TD><TD>Bit 7:</TD><TD>Error bit. Indicates that

-
- 1) umul_ppmm(high_prod, low_prod, multipler, multiplicand)
- multiplies two u32 integers MULTIPLER and MULTIPLICAND,
- 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. */
