45 places the quotient in QUOTIENT and the remainder in REMAINDER.
46 HIGH_NUMERATOR must be less than DENOMINATOR for correct operation.
47 If, in addition, the most significant bit of DENOMINATOR must be 1,
48 then the pre-processor symbol UDIV_NEEDS_NORMALIZATION is defined to 1.
49
50 4) sdiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
51 denominator). Like udiv_qrnnd but the numbers are signed. The
52 quotient is rounded towards 0.
53
54 5) count_leading_zeros(count, x) counts the number of zero-bits from
55 the msb to the first non-zero bit. This is the number of steps X
56 needs to be shifted left to set the msb. Undefined for X == 0.
57
58 6) add_ssaaaa(high_sum, low_sum, high_addend_1, low_addend_1,
59 high_addend_2, low_addend_2) adds two two-word unsigned integers,
60 composed by HIGH_ADDEND_1 and LOW_ADDEND_1, and HIGH_ADDEND_2 and
61 LOW_ADDEND_2 respectively. The result is placed in HIGH_SUM and
62 LOW_SUM. Overflow (i.e. carry out) is not stored anywhere, and is
63 lost.
64
65 7) sub_ddmmss(high_difference, low_difference, high_minuend,
66 low_minuend, high_subtrahend, low_subtrahend) subtracts two
67 two-word unsigned integers, composed by HIGH_MINUEND_1 and
68 LOW_MINUEND_1, and HIGH_SUBTRAHEND_2 and LOW_SUBTRAHEND_2
69 respectively. The result is placed in HIGH_DIFFERENCE and
70 LOW_DIFFERENCE. Overflow (i.e. carry out) is not stored anywhere,
71 and is lost.
72
73 If any of these macros are left undefined for a particular CPU,
74 C macros are used. */

274 tristate "Parallel printer support"
275 depends on PARPORT
276 ---help---
277 If you intend to attach a printer to the parallel port of your Linux
278 box (as opposed to using a serial printer; if the connector at the
279 printer has 9 or 25 holes ["female"], then it's serial), say Y.
280 Also read the Printing-HOWTO, available from
281 <http://www.tldp.org/docs.html#howto>.
282
283 It is possible to share one parallel port among several devices
284 (e.g. printer and ZIP drive) and it is safe to compile the
285 corresponding drivers into the kernel. If you want to compile this
286 driver as a module however, choose M here and read
287 <file:Documentation/parport.txt>. The module will be called lp.
288
289 If you have several parallel ports, you can specify which ports to
290 use with the "lp" kernel command line option. (Try "man bootparam"
291 or see the documentation of your boot loader (silo) about how to pass
292 options to the kernel at boot time.) The syntax of the "lp" command
293 line option can be found in <file:drivers/char/lp.c>.
294
295 If you have more than 8 printers, you need to increase the LP_NO
296 macro in lp.c and the PARPORT_MAX macro in parport.h.

448 tristate "Support for user-space parallel port device drivers"
449 depends on PARPORT
450 ---help---
451 Saying Y to this adds support for /dev/parport device nodes. This
452 is needed for programs that want portable access to the parallel
453 port, for instance deviceid (which displays Plug-and-Play device
454 IDs).
455
456 This is the parallel port equivalent of SCSI generic support (sg).
457 It is safe to say N to this -- it is not needed for normal printing
458 or parallel port CD-ROM/disk support.
459
460 To compile this driver as a module, choose M here: the
461 module will be called ppdev.

144 The 'zlib' compression library provides in-memory compression and
145 decompression functions, including integrity checks of the uncompressed
146 data. This version of the library supports only one compression method
147 (deflation) but other algorithms may be added later and will have the same
148 stream interface.
149
150 For compression the application must provide the output buffer and
151 may optionally provide the input buffer for optimization. For decompression,
152 the application must provide the input buffer and may optionally provide
153 the output buffer for optimization.
154
155 Compression can be done in a single step if the buffers are large
156 enough (for example if an input file is mmap'ed), or can be done by
157 repeated calls of the compression function. In the latter case, the
158 application must provide more input and/or consume the output
159 (providing more output space) before each call.

188 The application must update next_in and avail_in when avail_in has

190 has dropped to zero. The application must initialize zalloc, zfree and
191 opaque before calling the init function. All other fields are set by the
192 compression library and must not be updated by the application.
193
194 The opaque value provided by the application will be passed as the first
195 parameter for calls of zalloc and zfree. This can be useful for custom
196 memory management. The compression library attaches no meaning to the
197 opaque value.
198
199 zalloc must return Z_NULL if there is not enough memory for the object.
200 On 16-bit systems, the functions zalloc and zfree must be able to allocate
201 exactly 65536 bytes, but will not be required to allocate more than this
202 if the symbol MAXSEG_64K is defined (see zconf.h). WARNING: On MSDOS,
203 pointers returned by zalloc for objects of exactly 65536 bytes *must*
204 have their offset normalized to zero. The default allocation function
205 provided by this library ensures this (see zutil.c). To reduce memory
206 requirements and avoid any allocation of 64K objects, at the expense of
207 compression ratio, compile the library with -DMAX_WBITS=14 (see zconf.h).
208
209 The fields total_in and total_out can be used for statistics or
210 progress reports. After compression, total_in holds the total size of
211 the uncompressed data and may be saved for use in the decompressor
212 (particularly if the decompressor wants to decompress everything in
213 a single step).

284 (until there is no more input data or no more space in the output buffer).

287 one of the actions is possible, by providing more input and/or consuming
288 more output, and updating the next_* and avail_* values accordingly.

293 If the parameter flush is set to Z_PARTIAL_FLUSH or Z_PACKET_FLUSH,
294 inflate flushes as much output as possible to the output buffer. The
295 flushing behavior of inflate is not specified for values of the flush
296 parameter other than Z_PARTIAL_FLUSH, Z_PACKET_FLUSH or Z_FINISH, but the
297 current implementation actually flushes as much output as possible
298 anyway. For Z_PACKET_FLUSH, inflate checks that once all the input data
299 has been consumed, it is expecting to see the length field of a stored
300 block; if not, it returns Z_DATA_ERROR.
301
302 inflate() should normally be called until it returns Z_STREAM_END or an
303 error. However if all decompression is to be performed in a single step
304 (a single call of inflate), the parameter flush should be set to
305 Z_FINISH. In this case all pending input is processed and all pending
306 output is flushed; avail_out must be large enough to hold all the
307 uncompressed data. (The size of the uncompressed data may have been saved
308 by the compressor for this purpose.) The next operation on this stream must
309 be inflateEnd to deallocate the decompression state. The use of Z_FINISH
310 is never required, but can be used to inform inflate that a faster routine
311 may be used for the single inflate() call.
312
313 inflate() returns Z_OK if some progress has been made (more input
314 processed or more output produced), Z_STREAM_END if the end of the
315 compressed data has been reached and all uncompressed output has been
316 produced, Z_DATA_ERROR if the input data was corrupted, Z_STREAM_ERROR if
317 the stream structure was inconsistent (for example if next_in or next_out
318 was NULL), Z_MEM_ERROR if there was not enough memory, Z_BUF_ERROR if no
319 progress is possible or if there was not enough room in the output buffer
320 when Z_FINISH is used. In the Z_DATA_ERROR case, the application may then
321 call inflateSync to look for a good compression block. */

340 This is another version of inflateInit with more compression options. The
341 fields next_out, zalloc and zfree must be initialized before by the caller.
342
343 The windowBits parameter is the base two logarithm of the maximum window
344 size (the size of the history buffer). It should be in the range 8..15 for
345 this version of the library (the value 16 will be allowed soon). The
346 default value is 15 if inflateInit is used instead. If a compressed stream
347 with a larger window size is given as input, inflate() will return with
348 the error code Z_DATA_ERROR instead of trying to allocate a larger window.
349
350 If next_out is not null, the library will use this buffer for the history
351 buffer; the buffer must either be large enough to hold the entire output
352 data, or have at least 1<<windowBits bytes. If next_out is null, the
353 library will allocate its own buffer (and leave next_out null). next_in
354 need not be provided here but must be provided by the application for the
355 next call of inflate().
356
357 If the history buffer is provided by the application, next_out must
358 never be changed by the application since the decompressor maintains
359 history information inside this buffer from call to call; the application
360 can only reset next_out to the beginning of the history buffer when
361 avail_out is zero and all output has been consumed.
362
363 inflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was
364 not enough memory, Z_STREAM_ERROR if a parameter is invalid (such as
365 windowBits < 8). msg is set to null if there is no error message.

377 if no more input was provided, Z_DATA_ERROR if no marker has been found,

379 case, the application may save the current current value of total_in which

703 Notes beyond the 1.93a appnote.txt:
704
705 1. Distance pointers never point before the beginning of the output
706 stream.
707 2. Distance pointers can point back across blocks, up to 32k away.
708 3. There is an implied maximum of 7 bits for the bit length table and
709 15 bits for the actual data.
710 4. If only one code exists, then it is encoded using one bit. (Zero
711 would be more efficient, but perhaps a little confusing.) If two
712 codes exist, they are coded using one bit each (0 and 1).
713 5. There is no way of sending zero distance codes--a dummy must be
714 sent if there are none. (History: a pre 2.0 version of PKZIP would
715 store blocks with no distance codes, but this was discovered to be
716 too harsh a criterion.) Valid only for 1.93a. 2.04c does allow
717 zero distance codes, which is sent as one code of zero bits in
718 length.
719 6. There are up to 286 literal/length codes. Code 256 represents the
720 end-of-block. Note however that the static length tree defines
721 288 codes just to fill out the Huffman codes. Codes 286 and 287
722 cannot be used though, since there is no length base or extra bits
723 defined for them. Similarily, there are up to 30 distance codes.
724 However, static trees define 32 codes (all 5 bits) to fill out the
725 Huffman codes, but the last two had better not show up in the data.
726 7. Unzip can check dynamic Huffman blocks for complete code sets.
727 The exception is that a single code would not be complete (see #4).
728 8. The five bits following the block type is really the number of
729 literal codes sent minus 257.
730 9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits
731 (1+6+6). Therefore, to output three times the length, you output
732 three codes (1+1+1), whereas to output four times the same length,
733 you only need two codes (1+3). Hmm.
734 10. In the tree reconstruction algorithm, Code = Code + Increment
735 only if BitLength(i) is not zero. (Pretty obvious.)
736 11. Correction: 4 Bits: # of Bit Length codes - 4 (4 - 19)
737 12. Note: length code 284 can represent 227-258, but length code 285
738 really is 258. The last length deserves its own, short code
739 since it gets used a lot in very redundant files. The length
740 258 is special since 258 - 3 (the min match length) is 255.
741 13. The literal/length and distance code bit lengths are read as a
742 single stream of lengths. It is possible (and advantageous) for
743 a repeat code (16, 17, or 18) to go across the boundary between
744 the two sets of lengths.

1191 Huffman code decoding is performed using a multi-level table lookup.
1192 The fastest way to decode is to simply build a lookup table whose
1193 size is determined by the longest code. However, the time it takes
1194 to build this table can also be a factor if the data being decoded
1195 is not very long. The most common codes are necessarily the
1196 shortest codes, so those codes dominate the decoding time, and hence
1197 the speed. The idea is you can have a shorter table that decodes the
1198 shorter, more probable codes, and then point to subsidiary tables for
1199 the longer codes. The time it costs to decode the longer codes is
1200 then traded against the time it takes to make longer tables.
1201
1202 This results of this trade are in the variables lbits and dbits
1203 below. lbits is the number of bits the first level table for literal/
1204 length codes can decode in one step, and dbits is the same thing for
1205 the distance codes. Subsequent tables are also less than or equal to
1206 those sizes. These values may be adjusted either when all of the
1207 codes are shorter than that, in which case the longest code length in
1208 bits is used, or when the shortest code is *longer* than the requested
1209 table size, in which case the length of the shortest code in bits is
1210 used.
1211
1212 There are two different values for the two tables, since they code a
1213 different number of possibilities each. The literal/length table
1214 codes 286 possible values, or in a flat code, a little over eight
1215 bits. The distance table codes 30 possible values, or a little less
1216 than five bits, flat. The optimum values for speed end up being
1217 about one bit more than those, so lbits is 8+1 and dbits is 5+1.
1218 The optimum values may differ though from machine to machine, and
1219 possibly even between compilers. Your mileage may vary.
