- * PIC AS DEVICE ZERO
- * ------------------
- *
- * PIC handles PCI/X busses.  PCI/X requires that the 'bridge' (i.e. PIC)
- * be designated as 'device 0'.   That is a departure from earlier SGI
- * PCI bridges.  Because of that we use config space 1 to access the
- * config space of the first actual PCI device on the bus. 
- * Here's what the PIC manual says:
- *
- *     The current PCI-X bus specification now defines that the parent
- *     hosts bus bridge (PIC for example) must be device 0 on bus 0. PIC
- *     reduced the total number of devices from 8 to 4 and removed the
- *     device registers and windows, now only supporting devices 0,1,2, and
- *     3. PIC did leave all 8 configuration space windows. The reason was
- *     there was nothing to gain by removing them. Here in lies the problem.
- *     The device numbering we do using 0 through 3 is unrelated to the device
- *     numbering which PCI-X requires in configuration space. In the past we
- *     correlated Configs pace and our device space 0 <-> 0, 1 <-> 1, etc.
- *     PCI-X requires we start a 1, not 0 and currently the PX brick
- *     does associate our:
- * 
- *         device 0 with configuration space window 1,
- *         device 1 with configuration space window 2, 
- *         device 2 with configuration space window 3,
- *         device 3 with configuration space window 4.
- *
- * The net effect is that all config space access are off-by-one with 
- * relation to other per-slot accesses on the PIC.   
- * Here is a table that shows some of that:
- *
- *                               Internal Slot#
- *           |
- *           |     0         1        2         3
- * ----------|---------------------------------------
- * config    |  0x21000   0x22000  0x23000   0x24000
- *           |
- * even rrb  |  0[0]      n/a      1[0]      n/a        [] == implied even/odd
- *           |
- * odd rrb   |  n/a       0[1]     n/a       1[1]
- *           |
- * int dev   |  00       01        10        11
- *           |
- * ext slot# |  1        2         3         4

+          Saying Y to this adds support for /dev/parport device nodes.  This
+          is needed for programs that want portable access to the parallel
+          port, for instance deviceid (which displays Plug-and-Play device
+          IDs).
+
+          This is the parallel port equivalent of SCSI generic support (sg).
+          It is safe to say N to this -- it is not needed for normal printing
+          or parallel port CD-ROM/disk support.
+
+          To compile this driver as a module, choose M here: the

-  Performs one or both of the following actions:

-    enough room in the output buffer), next_in is updated and processing
-    will resume at this point for the next call of inflate().
-
-  - Provide more output starting at next_out and update next_out and avail_out
-    accordingly.  inflate() always provides as much output as possible
-    (until there is no more input data or no more space in the output buffer).
-
-  Before the call of inflate(), the application should ensure that at least
-  one of the actions is possible, by providing more input and/or consuming
-  more output, and updating the next_* and avail_* values accordingly.
-  The application can consume the uncompressed output when it wants, for
-  example when the output buffer is full (avail_out == 0), or after each
-  call of inflate().
-
-    If the parameter flush is set to Z_PARTIAL_FLUSH or Z_PACKET_FLUSH,
-  inflate flushes as much output as possible to the output buffer. The
-  flushing behavior of inflate is not specified for values of the flush
-  parameter other than Z_PARTIAL_FLUSH, Z_PACKET_FLUSH or Z_FINISH, but the
-  current implementation actually flushes as much output as possible
-  anyway.  For Z_PACKET_FLUSH, inflate checks that once all the input data
-  has been consumed, it is expecting to see the length field of a stored
-  block; if not, it returns Z_DATA_ERROR.
-
-    inflate() should normally be called until it returns Z_STREAM_END or an
-  error. However if all decompression is to be performed in a single step
-  (a single call of inflate), the parameter flush should be set to
-  Z_FINISH. In this case all pending input is processed and all pending
-  output is flushed; avail_out must be large enough to hold all the
-  uncompressed data. (The size of the uncompressed data may have been saved
-  by the compressor for this purpose.) The next operation on this stream must
-  be inflateEnd to deallocate the decompression state. The use of Z_FINISH
-  is never required, but can be used to inform inflate that a faster routine
-  may be used for the single inflate() call.
-
-    inflate() returns Z_OK if some progress has been made (more input
-  processed or more output produced), Z_STREAM_END if the end of the
-  compressed data has been reached and all uncompressed output has been
-  produced, Z_DATA_ERROR if the input data was corrupted, Z_STREAM_ERROR if
-  the stream structure was inconsistent (for example if next_in or next_out
-  was NULL), Z_MEM_ERROR if there was not enough memory, Z_BUF_ERROR if no
-  progress is possible or if there was not enough room in the output buffer

-   size (the size of the history buffer).  It should be in the range 8..15 for
-   this version of the library (the value 16 will be allowed soon). The
-   default value is 15 if inflateInit is used instead. If a compressed stream
-   with a larger window size is given as input, inflate() will return with
-   the error code Z_DATA_ERROR instead of trying to allocate a larger window.
-
-     If next_out is not null, the library will use this buffer for the history

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

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