/*
* Hypercall interface description:
* Used by scripts/gen_hypercall.awk to generate hypercall prototypes and call
* sequences.
*
* Syntax is like a prototype, but without return type and without the ";" at
* the end. Pointer types will be automatically converted to use the
* XEN_GUEST_HANDLE_PARAM() macro. Handlers with no parameters just use a
* definition like "fn()".
* Hypercall/function names are without the leading "__HYPERVISOR_"/"do_"
* strings.
*
* The return type of a class of prototypes using the same prefix is set via:
* rettype: <prefix> <type>
* Default return type is "long". A return type for a prefix can be set only
* once and it needs to be set before that prefix is being used via the
* "prefix:" directive.
*
* The prefix of the prototypes is set via a line:
* prefix: <prefix> ...
* Multiple prefixes are possible (restriction see below). Prefixes are without
* a trailing "_". The current prefix settings are active until a new "prefix:"
* line.
*
* Caller macros are suffixed with a selectable name via lines like:
* caller: <suffix>
* When a caller suffix is active, there is only one active prefix allowed.
*
* With a "defhandle:" line it is possible to add a DEFINE_XEN_GUEST_HANDLE()
* to the generated header:
* defhandle: <handle-type> [<type>]
* Without specifying <type> only a DEFINE_XEN_GUEST_HANDLE(<handle-type>)
* will be generated, otherwise it will be a
* __DEFINE_XEN_GUEST_HANDLE(<handle-type>, <type>) being generated. Note that
* the latter will include the related "const" handle "const_<handle-type>".
*
* In order to support using coding style compliant pointers in the
* prototypes it is possible to add translation entries to generate the correct
* handle types:
* handle: <handle-type> <type>
* This will result in the prototype translation from "<type> *" to
* "XEN_GUEST_HANDLE_PARAM(<handle-type>)".
*
* The hypercall handler calling code will be generated from a final table in
* the source file, which is started via the line:
* table: <caller> <caller> ...
* with the <caller>s specifying the designated caller macro of each column of
* the table. Any column of a <caller> not having been set via a "caller:"
* line will be ignored.
* The first column of the table contains the hypercall/prototype, each
* <caller> column contains the prefix for the function to use for that caller.
* A function prefix can be annotated with a priority by adding ":<prio>" to it
* ("1" being the highest priority, higher numbers mean lower priority, no
* priority specified is the lowest priority). The generated code will try to
* achieve better performance for calling high priority handlers.
* A column not being supported by a <caller> is marked with "-". Lines with all
* entries being "-" after removal of inactive <caller> columns are ignored.
*
* This file is being preprocessed using $(CPP), so #ifdef CONFIG_* conditionals
* are possible.
*/
/*
* Cppcheck thinks this file needs to be analysed because it is preprocessed by
* the compiler, but it gets confused because this file does not contains C
* code. Hence protect the code when CPPCHECK is used.
