+===============
+SELINUX SUPPORT
+===============
+
+The security class "key" has been added to SELinux so that mandatory access
+controls can be applied to keys created within various contexts. This support
+is preliminary, and is likely to change quite significantly in the near future.
+Currently, all of the basic permissions explained above are provided in SELinux
+as well; SE Linux is simply invoked after all basic permission checks have been
+performed.
+
+Each key is labeled with the same context as the task to which it belongs.
+Typically, this is the same task that was running when the key was created.
+The default keyrings are handled differently, but in a way that is very
+intuitive:
+
+ (*) The user and user session keyrings that are created when the user logs in
+ are currently labeled with the context of the login manager.
+
+ (*) The keyrings associated with new threads are each labeled with the context
+ of their associated thread, and both session and process keyrings are
+ handled similarly.
+
+Note, however, that the default keyrings associated with the root user are
+labeled with the default kernel context, since they are created early in the
+boot process, before root has a chance to log in.
+
+
================
NEW PROCFS FILES
================
It is not safe to sleep in this method; the caller may hold spinlocks.
+ (*) void (*revoke)(struct key *key);
+
+ This method is optional. It is called to discard part of the payload
+ data upon a key being revoked. The caller will have the key semaphore
+ write-locked.
+
+ It is safe to sleep in this method, though care should be taken to avoid
+ a deadlock against the key semaphore.
+

(*) void (*destroy)(struct key *key);
This method is optional. It is called to discard the payload data on a key
See Documentation/IO-mapping.txt for how to access device memory.
- You still need to call request_region() for I/O regions and
-request_mem_region() for memory regions to make sure nobody else is using the
-same device.
+ The device driver needs to call pci_request_region() to make sure
+no other device is already using the same resource. The driver is expected
+to determine MMIO and IO Port resource availability _before_ calling
+pci_enable_device(). Conversely, drivers should call pci_release_region()
+_after_ calling pci_disable_device(). The idea is to prevent two devices
+colliding on the same address range.
+
+Generic flavors of pci_request_region() are request_mem_region()
+(for MMIO ranges) and request_region() (for IO Port ranges).
+Use these for address resources that are not described by "normal" PCI
+interfaces (e.g. BAR).
All interrupt handlers should be registered with SA_SHIRQ and use the devid
to map IRQs to devices (remember that all PCI interrupts are shared).

/*
The 'zlib' compression library provides in-memory compression and
application must provide more input and/or consume the output
(providing more output space) before each call.
+ The compressed data format used by default by the in-memory functions is
+ the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
+ around a deflate stream, which is itself documented in RFC 1951.
+
The library also supports reading and writing files in gzip (.gz) format
with an interface similar to that of stdio.
+ The zlib format was designed to be compact and fast for use in memory
+ and on communications channels. The gzip format was designed for single-
+ file compression on file systems, has a larger header than zlib to maintain
+ directory information, and uses a different, slower check method than zlib.
+
The library does not install any signal handler. The decoder checks
the consistency of the compressed data, so the library should never
crash even in case of corrupted input.

+ buffer becomes empty or the output buffer becomes full. It may introduce
+ some output latency (reading input without producing any output) except when
+ forced to flush.
The detailed semantics are as follows. inflate performs one or both of the
following actions:
must be called again after making room in the output buffer because there
might be more output pending.
- If the parameter flush is set to Z_SYNC_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_SYNC_FLUSH
- and Z_FINISH, but the current implementation actually flushes as much output
- as possible anyway.
+ The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH,
+ Z_FINISH, or Z_BLOCK. Z_SYNC_FLUSH requests that inflate() flush as much
+ output as possible to the output buffer. Z_BLOCK requests that inflate() stop
+ if and when it gets to the next deflate block boundary. When decoding the
+ zlib or gzip format, this will cause inflate() to return immediately after
+ the header and before the first block. When doing a raw inflate, inflate()
+ will go ahead and process the first block, and will return when it gets to
+ the end of that block, or when it runs out of data.
+
+ The Z_BLOCK option assists in appending to or combining deflate streams.
+ Also to assist in this, on return inflate() will set strm->data_type to the
+ number of unused bits in the last byte taken from strm->next_in, plus 64
+ if inflate() is currently decoding the last block in the deflate stream,
+ plus 128 if inflate() returned immediately after decoding an end-of-block
+ code or decoding the complete header up to just before the first byte of the
+ deflate stream. The end-of-block will not be indicated until all of the
+ uncompressed data from that block has been written to strm->next_out. The
+ number of unused bits may in general be greater than seven, except when
+ bit 7 of data_type is set, in which case the number of unused bits will be
+ less than eight.
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
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
+ is never required, but can be used to inform inflate that a faster approach
may be used for the single inflate() call.
- If a preset dictionary is needed at this point (see inflateSetDictionary
- below), inflate sets strm-adler to the adler32 checksum of the
- dictionary chosen by the compressor and returns Z_NEED_DICT; otherwise
- it sets strm->adler to the adler32 checksum of all output produced
- so far (that is, total_out bytes) and returns Z_OK, Z_STREAM_END or
- an error code as described below. At the end of the stream, inflate()
- checks that its computed adler32 checksum is equal to that saved by the
- compressor and returns Z_STREAM_END only if the checksum is correct.
+ In this implementation, inflate() always flushes as much output as
+ possible to the output buffer, and always uses the faster approach on the
+ first call. So the only effect of the flush parameter in this implementation
+ is on the return value of inflate(), as noted below, or when it returns early
+ because Z_BLOCK is used.
+
+ If a preset dictionary is needed after this call (see inflateSetDictionary
+ below), inflate sets strm->adler to the adler32 checksum of the dictionary
+ chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
+ strm->adler to the adler32 checksum of all output produced so far (that is,
+ total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
+ below. At the end of the stream, inflate() checks that its computed adler32
+ checksum is equal to that saved by the compressor and returns Z_STREAM_END
+ only if the checksum is correct.
+
+ inflate() will decompress and check either zlib-wrapped or gzip-wrapped
+ deflate data. The header type is detected automatically. Any information
+ contained in the gzip header is not retained, so applications that need that
+ information should instead use raw inflate, see inflateInit2() below, or
+ inflateBack() and perform their own processing of the gzip header and
+ trailer.
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_NEED_DICT if a
preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
- corrupted (input stream not conforming to the zlib format or incorrect
- adler32 checksum), 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 when Z_FINISH is used. In the Z_DATA_ERROR
- case, the application may then call inflateSync to look for a good
- compression block.

+ Z_BUF_ERROR if no progress is possible or if there was not enough room in the

+ inflate() can be called again with more input and more output space to

*/
The windowBits parameter is the base two logarithm of the maximum window
size (the size of the history buffer). It should be in the range 8..15 for
this version of the library. 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.
-
- inflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough
- memory, Z_STREAM_ERROR if a parameter is invalid (such as a negative
- memLevel). msg is set to null if there is no error message. inflateInit2
- does not perform any decompression apart from reading the zlib header if
- present: this will be done by inflate(). (So next_in and avail_in may be
- modified, but next_out and avail_out are unchanged.)
+ instead. windowBits must be greater than or equal to the windowBits value
+ provided to deflateInit2() while compressing, or it must be equal to 15 if
+ deflateInit2() was not used. 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.
+
+ windowBits can also be -8..-15 for raw inflate. In this case, -windowBits
+ determines the window size. inflate() will then process raw deflate data,
+ not looking for a zlib or gzip header, not generating a check value, and not
+ looking for any check values for comparison at the end of the stream. This
+ is for use with other formats that use the deflate compressed data format
+ such as zip. Those formats provide their own check values. If a custom
+ format is developed using the raw deflate format for compressed data, it is
+ recommended that a check value such as an adler32 or a crc32 be applied to
+ the uncompressed data as is done in the zlib, gzip, and zip formats. For
+ most applications, the zlib format should be used as is. Note that comments
+ above on the use in deflateInit2() applies to the magnitude of windowBits.
+
+ windowBits can also be greater than 15 for optional gzip decoding. Add
+ 32 to windowBits to enable zlib and gzip decoding with automatic header
+ detection, or add 16 to decode only the gzip format (the zlib format will
+ return a Z_DATA_ERROR). If a gzip stream is being decoded, strm->adler is
+ a crc32 instead of an adler32.
+
+ inflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough
+ memory, Z_STREAM_ERROR if a parameter is invalid (such as a null strm). msg
+ is set to null if there is no error message. inflateInit2 does not perform
+ any decompression apart from reading the zlib header if present: this will
+ be done by inflate(). (So next_in and avail_in may be modified, but next_out
+ and avail_out are unchanged.)

- 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.

+ Decode literal, length, and distance codes and write out the resulting

+ When large enough input and output buffers are supplied to inflate(), for

+ inflate execution time is spent in this routine.

+
+ Notes:
+
+ - The maximum input bits used by a length/distance pair is 15 bits for the
+ length code, 5 bits for the length extra, 15 bits for the distance code,
+ and 13 bits for the distance extra. This totals 48 bits, or six bytes.
+ Therefore if strm->avail_in >= 6, then there is enough input to avoid
+ checking for available input while decoding.
+
+ - The maximum bytes that a single length/distance pair can output is 258
+ bytes, which is the maximum length that can be coded. inflate_fast()
+ requires strm->avail_out >= 258 for each loop to avoid checking for

+ inflate() uses a state machine to process as much input data and generate as
+ much output data as possible before returning. The state machine is
+ structured roughly as follows:
+
+ for (;;) switch (state) {
+ ...
+ case STATEn:
+ if (not enough input data or output space to make progress)
+ return;
+ ... make progress ...
+ state = STATEm;
+ break;
+ ...
+ }
+
+ so when inflate() is called again, the same case is attempted again, and
+ if the appropriate resources are provided, the machine proceeds to the
+ next state. The NEEDBITS() macro is usually the way the state evaluates
+ whether it can proceed or should return. NEEDBITS() does the return if
+ the requested bits are not available. The typical use of the BITS macros
+ is:
+
+ NEEDBITS(n);
+ ... do something with BITS(n) ...
+ DROPBITS(n);
+
+ where NEEDBITS(n) either returns from inflate() if there isn't enough
+ input left to load n bits into the accumulator, or it continues. BITS(n)
+ gives the low n bits in the accumulator. When done, DROPBITS(n) drops
+ the low n bits off the accumulator. INITBITS() clears the accumulator
+ and sets the number of available bits to zero. BYTEBITS() discards just
+ enough bits to put the accumulator on a byte boundary. After BYTEBITS()
+ and a NEEDBITS(8), then BITS(8) would return the next byte in the stream.
+
+ NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return
+ if there is no input available. The decoding of variable length codes uses
+ PULLBYTE() directly in order to pull just enough bytes to decode the next
+ code, and no more.
+
+ Some states loop until they get enough input, making sure that enough
+ state information is maintained to continue the loop where it left off
+ if NEEDBITS() returns in the loop. For example, want, need, and keep
+ would all have to actually be part of the saved state in case NEEDBITS()
+ returns:
+
+ case STATEw:
+ while (want < need) {
+ NEEDBITS(n);
+ keep[want++] = BITS(n);
+ DROPBITS(n);
+ }
+ state = STATEx;
+ case STATEx:
+
+ As shown above, if the next state is also the next case, then the break
+ is omitted.
+
+ A state may also return if there is not enough output space available to
+ complete that state. Those states are copying stored data, writing a
+ literal byte, and copying a matching string.
+
+ When returning, a "goto inf_leave" is used to update the total counters,
+ update the check value, and determine whether any progress has been made
+ during that inflate() call in order to return the proper return code.
+ Progress is defined as a change in either strm->avail_in or strm->avail_out.
+ When there is a window, goto inf_leave will update the window with the last
+ output written. If a goto inf_leave occurs in the middle of decompression
+ and there is no window currently, goto inf_leave will create one and copy
+ output to the window for the next call of inflate().
+
+ In this implementation, the flush parameter of inflate() only affects the
+ return code (per zlib.h). inflate() always writes as much as possible to
+ strm->next_out, given the space available and the provided input--the effect
+ documented in zlib.h of Z_SYNC_FLUSH. Furthermore, inflate() always defers
+ the allocation of and copying into a sliding window until necessary, which
+ provides the effect documented in zlib.h for Z_FINISH when the entire input
+ stream available. So the only thing the flush parameter actually does is:
+ when flush is set to Z_FINISH, inflate() cannot return Z_OK. Instead it
+ will return Z_BUF_ERROR if it has not reached the end of the stream.

- 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.
+ Build a set of tables to decode the provided canonical Huffman code.
+ The code lengths are lens[0..codes-1]. The result starts at *table,
+ whose indices are 0..2^bits-1. work is a writable array of at least
+ lens shorts, which is used as a work area. type is the type of code
+ to be generated, CODES, LENS, or DISTS. On return, zero is success,
+ -1 is an invalid code, and +1 means that ENOUGH isn't enough. table
+ on return points to the next available entry's address. bits is the
+ requested root table index bits, and on return it is the actual root
+ table index bits. It will differ if the request is greater than the
+ longest code or if it is less than the shortest code.

+ for codes with equal lengths. Then the code starts with all zero bits

+ increments for the same length, and zeros are appended as the length
+ increases. For the deflate format, these bits are stored backwards

+ are incremented backwards.
+
+ This routine assumes, but does not check, that all of the entries in
+ lens[] are in the range 0..MAXBITS. The caller must assure this.
+ 1..MAXBITS is interpreted as that code length. zero means that that
+ symbol does not occur in this code.
+

+ creating from that a table of starting indices for each length in the
+ sorted table, and then entering the symbols in order in the sorted
+ table. The sorted table is work[], with that space being provided by
+ the caller.
+
+ The length counts are used for other purposes as well, i.e. finding

+ *
+ * This is a driver for the pcm3052 codec chip (codenamed Onyx)

+ *
+ * The Onyx codec has the following connections (listed by the bit
+ * to be used in aoa_codec.connected):
+ * 0: analog output
+ * 1: digital output
+ * 2: line input
+ * 3: microphone input
+ * Note that even though I know of no machine that has for example
+ * the digital output connected but not the analog, I have handled
+ * all the different cases in the code so that this driver may serve
+ * as a good example of what to do.
+ *
+ * NOTE: This driver assumes that there's at most one chip to be
+ * used with one alsa card, in form of creating all kinds
+ * of mixer elements without regard for their existence.
+ * But snd-aoa assumes that there's at most one card, so
+ * this means you can only have one onyx on a system. This
+ * should probably be fixed by changing the assumption of
+ * having just a single card on a system, and making the
+ * 'card' pointer accessible to anyone who needs it instead
+ * of hiding it in the aoa_snd_* functions...

+ * Apple Onboard Audio driver for tas codec
+ *
+ * Copyright 2006 Johannes Berg <johannes@sipsolutions.net>
+ *
+ * GPL v2, can be found in COPYING.
+ *
+ * Open questions:
+ * - How to distinguish between 3004 and versions?
+ *
+ * FIXMEs:
+ * - This codec driver doesn't honour the 'connected'
+ * property of the aoa_codec struct, hence if
+ * it is used in machines where not everything is
+ * connected it will display wrong mixer elements.
+ * - Driver assumes that the microphone is always
+ * monaureal and connected to the right channel of
+ * the input. This should also be a codec-dependent
+ * flag, maybe the codec should have 3 different
+ * bits for the three different possibilities how
+ * it can be hooked up...
+ * But as long as I don't see any hardware hooked
+ * up that way...
+ * - As Apple notes in their code, the tas3004 seems
+ * to delay the right channel by one sample. You can
+ * see this when for example recording stereo in
+ * audacity, or recording the tas output via cable
+ * on another machine (use a sinus generator or so).
+ * I tried programming the BiQuads but couldn't
+ * make the delay work, maybe someone can read the
+ * datasheet and fix it. The relevant Apple comment
+ * is in AppleTAS3004Audio.cpp lines 1637 ff. Note
+ * that their comment describing how they program
+ * the filters sucks...
+ *
+ * Other things:
+ * - this should actually register *two* aoa_codec
+ * structs since it has two inputs. Then it must
+ * use the prepare callback to forbid running the
+ * secondary output on a different clock.
+ * Also, whatever bus knows how to do this must
+ * provide two soundbus_dev devices and the fabric
+ * must be able to link them correctly.
+ *
+ * I don't even know if Apple ever uses the second
+ * port on the tas3004 though, I don't think their
+ * i2s controllers can even do it. OTOH, they all
+ * derive the clocks from common clocks, so it
+ * might just be possible. The framework allows the
+ * codec to refine the transfer_info items in the
+ * usable callback, so we can simply remove the
+ * rates the second instance is not using when it
+ * actually is in use.
+ * Maybe we'll need to make the sound busses have
+ * a 'clock group id' value so the codec can
+ * determine if the two outputs can be driven at
+ * the same time. But that is likely overkill, up
+ * to the fabric to not link them up incorrectly,
+ * and up to the hardware designer to not wire
+ * them up in some weird unusable way.

*
* The AZF3328 chip (note: AZF3328, *not* AZT3328, that's just the driver name
* for compatibility reasons) has the following features:
*
* - builtin AC97 conformant codec (SNR over 80dB)
- * (really AC97 compliant?? I really doubt it when looking
- * at the mixer register layout)
+ * Note that "conformant" != "compliant"!! this chip's mixer register layout
+ * *differs* from the standard AC97 layout:
+ * they chose to not implement the headphone register (which is not a
+ * problem since it's merely optional), yet when doing this, they committed
+ * the grave sin of letting other registers follow immediately instead of
+ * keeping a headphone dummy register, thereby shifting the mixer register
+ * addresses illegally. So far unfortunately it looks like the very flexible
+ * ALSA AC97 support is still not enough to easily compensate for such a
+ * grave layout violation despite all tweaks and quirks mechanisms it offers.
* - builtin genuine OPL3
* - full duplex 16bit playback/record at independent sampling rate
* - MPU401 (+ legacy address support) FIXME: how to enable legacy addr??
*
* TODO
* - test MPU401 MIDI playback etc.
- * - power management. See e.g. intel8x0 or cs4281.
- * This would be nice since the chip runs a bit hot, and it's *required*
- * anyway for proper ACPI power management.
+ * - add some power micro-management (disable various units of the card
+ * as long as they're unused). However this requires I/O ports which I
+ * haven't figured out yet and which thus might not even exist...
+ * The standard suspend/resume functionality could probably make use of
+ * some improvement, too...
* - figure out what all unknown port bits are responsible for
+ * - figure out some cleverly evil scheme to possibly make ALSA AC97 code
+ * fully accept our quite incompatible ""AC97"" mixer and thus save some
+ * code (but I'm not too optimistic that doing this is possible at all)
