                  Hidparser: Solaris implementation
		  _________________________________


Report descriptors  are  basically  made of  items.   Items  can  be  'Main'
items,  'Local' Items  and  'Global' Items. Local and  Global items  differ
in their  scope. Local  items  hold their value only   within the main item
in which  they are  defined  while global items retain their values through
out all main items  unless *redefined*.

Main Items  are  collection,  input, output and  feature and end collection
items. Each  of  the  main  items are represented by an 'entity_item' struc-
ture.  Solaris    maintains   global and  local items  as a  linked list of
entity_attribute   structures  in the 'entity_item' structure.  Since local
items are specific  to a main  item it   makes  sense to  keep  local items
with in the main item.  List   of   global  items can't be kept as a single
global list because they  can   get redefined in any  subsequent main  item
and Solaris won't be able  to   know what  will  be the value for each main
item. Hence they also  figure   in the list  maintained  by the entity_item
structure.

So how do we construct the tree ?

Each main item forms a sibling or child of another main item except for the
root  main  item which will  always be a Collection main item. Each collect-
ion item  should be closed  by  an end  collection.  So  root  collection's
sibling  will be an end  collection. Whatever  input,  output  and  feature
items  which fall inside  a collection (please  see a collection as '{' and
end  collection as '}' in  'C' language) will  form a child  of  the parent
collection  with each of  them  forming  a sibling  of  each  other. i.e if
an Input  main item comes  first within a  collection  then  it'll form the
child of  the collection  with the subsequent  main  items  being linked as
siblings  of each other.  When we reach an end collection, it must form the
sibling of  the collection.  This applies for nested collections  also. i.e
if a  collection falls within  another collection, it'll form  a  child  of
the  parent collection with  the 'input','output' and 'feature' main  items
falling within  the child collection forming a child  of child  collection.
Whatever falls  outside the child collection,but inside a parent collection
will form a sibling of the child collection.

When  hidparser starts, it'll get the raw  descriptor in a structure called
'hidparser_tok'  structure. Solaris  will  proceed by taking one byte first
(which sort of forms a header and  indicates  how many  to  follow for each
item for the 'item data') and then proceeds to take the  value for the item
(which is the item data). This  'hidparser_tok'  structure  contains a list
of global and local items. As  and when the parser encounters a global item
it'll add it to the global item list. The same applies for local items also.
The only difference is that if  a global item is getting redefined (i.e the
global item is already present  in the gitem list),  then "the global item"
(i.e one of the global item) is freed and the new one is put instead. Local
items can get redefined without  disturbing the earlier  values.  This goes
on till a main item is encountered. When a  main  item  is encountered  the
global item list  is copied over to the entity_item structure and the local
item list will start  where  the global item  list  stops ( in the 'entity_
attribute' list). Before we start on the next item the local item list will
be freed (in the hidparser_tok  structure) but the global item list will be
maintained since their scope is through out the report descriptor.

The two additions which has happened  in this  round  of  changes  are  the
support for push|pop and delimiter items. 'push' basically asks the  parser
to copy over the list of  global  items, while  'pop' takes the last pushed
list as the current one. The entity_attribute_stack forms a stack of global
item list pointers from which they can be pop-ed on the gitem list.'delimit-
er'items basically allows you to interpret the data that is  being received
differently depending on the way you use it and requires the parser to reco-
gnize only the first 'usage' (which is what Solaris does with my changes).

it a mouse).

Item format:

	------------------------------------
	|data|data(8)|tag(4),type(2),size(2)|
	------------------------------------
                            |<------'ch'---------->|

___________________________________________________________________________

'hidparser_ReportDescriptor()' will call  'hidparser_scan()'  first.  Hence
you will see the  'scanner'  output first.  The scanner will go through the
first byte and set hidparser_tok_token to the tag|type value. hidparser_tok
_leng  will be set to size and the 'data' part will be copied to tok_ text.
'hidparser_ReportDescriptor'  will   call  'hidparser_ItemList()'  to  take
charge of the rest of the parsing.

___________________________________________________________________________

hidparser:      scanner: index  = 0x0 ch = 0x5 [ = 0x00000101 = tag[0],
                                               type[1], size[1] ]

hidparser:      scanner: parsed_length = 1 <========size[1] [Type 1 = Global
			Tag[0] = Usage Page ]

___________________________________________________________________________

Here the length of 1 indicates that the parameter or value associated  with
the usage page is contained in the next character/byte.

___________________________________________________________________________

hidparser:      scanner: parsed_text[0] = 0x1,index = 0x1
___________________________________________________________________________

The next byte contains a value of 0x1. If you look at the usage table spec
you can see that value of 1 stands for Generic Desktop.
___________________________________________________________________________

hidparser:      scanner: lexical analyzer found 0x5 before translation
hidparser:      scanner: aindex  = 0x2
___________________________________________________________________________

Here  'hidparser_ItemList()'  would have  been called,   which  again calls
'hidparser_Items()'. The purpose of 'hidparser_Items()'  is to  get through
all the Items and break when it encounters a main item.  'hidparser_Items()
will  again  call  'hidparser_GlobalItem()'  and 'hidparser_LocalItem()' to
make a list of entity attributes in the hidparser_tok structure.
___________________________________________________________________________

hidparser:      hidparser_GlobalItem:index = 0x0 token = 0x4

___________________________________________________________________________

The above goes to gitem list.
___________________________________________________________________________


hidparser:      scanner: index  = 0x2 ch = 0x9 [ = 0x00001001 = tag[0],
			type[2], size[1]]
hidparser:      scanner: parsed_length = 1
hidparser:      scanner: parsed_text[0] = 0x8,index = 0x3
hidparser:      scanner: lexical analyzer found 0x9 before translation
hidparser:      scanner: aindex  = 0x4
hidparser:      hidparser_LocalItem:index = 0x2 token = 0x8
___________________________________________________________________________

The above goes to local item list in hidparser_tok_structure.
___________________________________________________________________________

hidparser:      scanner: index  = 0x4 ch = 0xa1 [= 0x10100001 = tag[a],
			type[0], size[1]]
hidparser:      scanner: parsed_length = 1	[ This is a main item ]
hidparser:      scanner: parsed_text[0] = 0x1,index = 0x5
hidparser:      scanner: lexical analyzer found 0xa1 before translation
hidparser:      scanner: aindex  = 0x6

____________________________________________________________________________

Here 'hidparser_Items()' will break and pass the control back to 'hidparser_
ItemList()' which will call 'hidparser_MainItem()'  to do things specific to
a main item (like allocating  an entity_item  structure  and returning it in
curr_ei).  'hidparser_MainItem()' will allocate an entity_item structure and
copy the gitem list from hidparser tok structure and add the local item list
to the end of global item list  (in  the  entity_item_attributes  member  of
entity_item structure).

____________________________________________________________________________

hidparser:      hidparser_MainItem:index = 0x4 token = 0xa0
hidparser:      scanner: index  = 0x6 ch = 0xa1
hidparser:      scanner: parsed_length = 1
hidparser:      scanner: parsed_text[0] = 0x0,index = 0x7
hidparser:      scanner: lexical analyzer found 0xa1 before translation
hidparser:      scanner: aindex  = 0x8
hidparser:      Start Collection:cache_ei = 0xcab8d220, curr_ei = 0xcab8d220

____________________________________________________________________________

This forms the root collection.  'cache_ei'  or the cached  entity_item will
always point to the last collection encountered.  Each entity_item structure
will have a pointer to the previous collection.  This is basically to remove
recursion when we support nested collections.  So if I have something like

Collection
	....
	Collection
		....
		Collection
		....
		End Collection
		....
	End collection
	....
End Collection

and if we assume  that  the parser is currently @ the third Collection item,
then cache_ei will point to the third collection, it's prev_ei will point to
the second collection and it's prev_ei will point to the root collection. As
we move down the first end collection, cache_ei would have changed to second
collection and so on.
____________________________________________________________________________

hidparser:      hidparser_MainItem:index = 0x6 token = 0xa0

____________________________________________________________________________

We encounter  another collection here [ so a nested collection ].  This   'ei'
will have a  global  item  list (only,  as there are no local items. Remember
that  we  preserve  global  item list  in  the  hidparser_tok_structure while
blanking out the local item list as we encounter a main item).
____________________________________________________________________________

hidparser:      scanner: index  = 0x8 ch = 0x85

hidparser:      hidparser_GlobalItem:index = 0x8 token = 0x84

As can be seen, the tree that Solaris constructs have carried over GI extra
which is the only difference. But that doesn't make a difference in the way
we handle data.

There are somethings to be noted at this point. If subsequently we encount-
er another  global item  which has already been defined (say report size),
then we  will go to the  global list  maintained in the 'hidparser_tok' st-
ructure and replace the already existant one  (i.e report size(0x10)  with
the new one ).

For end collection  main item, we don't attach the global item list to the
entity item structure.

The rest of the document is a continuation of where we left off the parsing.
The theory of operation is the same.
