-1. Preprocessor
-
-For variadic macros, stick with this C99-like syntax:
-
-#define DPRINTF(fmt, ...)                                       \
-    do { printf("IRQ: " fmt, ## __VA_ARGS__); } while (0)
-
-2. C types
-
-It should be common sense to use the right type, but we have collected
-a few useful guidelines here.
-
-2.1. Scalars
-
-If you're using "int" or "long", odds are good that there's a better type.
-If a variable is counting something, it should be declared with an
-unsigned type.
-
-If it's host memory-size related, size_t should be a good choice (use
-ssize_t only if required). Guest RAM memory offsets must use ram_addr_t,
-but only for RAM, it may not cover whole guest address space.
-
-If it's file-size related, use off_t.
-If it's file-offset related (i.e., signed), use off_t.
-If it's just counting small numbers use "unsigned int";
-(on all but oddball embedded systems, you can assume that that
-type is at least four bytes wide).
-
-In the event that you require a specific width, use a standard type
-like int32_t, uint32_t, uint64_t, etc.  The specific types are
-mandatory for VMState fields.
-
-Don't use Linux kernel internal types like u32, __u32 or __le32.
-
-Use hwaddr for guest physical addresses except pcibus_t
-for PCI addresses.  In addition, ram_addr_t is a QEMU internal address
-space that maps guest RAM physical addresses into an intermediate
-address space that can map to host virtual address spaces.  Generally
-speaking, the size of guest memory can always fit into ram_addr_t but
-it would not be correct to store an actual guest physical address in a
-ram_addr_t.
-
-Use target_ulong (or abi_ulong) for CPU virtual addresses, however
-devices should not need to use target_ulong.
-
-Of course, take all of the above with a grain of salt.  If you're about
-to use some system interface that requires a type like size_t, pid_t or
-off_t, use matching types for any corresponding variables.
-
-Also, if you try to use e.g., "unsigned int" as a type, and that
-conflicts with the signedness of a related variable, sometimes
-it's best just to use the *wrong* type, if "pulling the thread"
-and fixing all related variables would be too invasive.
-
-Finally, while using descriptive types is important, be careful not to
-go overboard.  If whatever you're doing causes warnings, or requires
-casts, then reconsider or ask for help.
-
-2.2. Pointers
-
-Ensure that all of your pointers are "const-correct".
-Unless a pointer is used to modify the pointed-to storage,
-give it the "const" attribute.  That way, the reader knows
-up-front that this is a read-only pointer.  Perhaps more
-importantly, if we're diligent about this, when you see a non-const
-pointer, you're guaranteed that it is used to modify the storage
-it points to, or it is aliased to another pointer that is.
-
-2.3. Typedefs
-Typedefs are used to eliminate the redundant 'struct' keyword.
-
-2.4. Reserved namespaces in C and POSIX
-Underscore capital, double underscore, and underscore 't' suffixes should be
-avoided.
-
-3. Low level memory management
-
-Use of the malloc/free/realloc/calloc/valloc/memalign/posix_memalign
-APIs is not allowed in the QEMU codebase. Instead of these routines,
-use the GLib memory allocation routines g_malloc/g_malloc0/g_new/
-g_new0/g_realloc/g_free or QEMU's qemu_memalign/qemu_blockalign/qemu_vfree
-APIs.
-
-Please note that g_malloc will exit on allocation failure, so there
-is no need to test for failure (as you would have to with malloc).
-Calling g_malloc with a zero size is valid and will return NULL.
-
-Memory allocated by qemu_memalign or qemu_blockalign must be freed with
-qemu_vfree, since breaking this will cause problems on Win32.
-
-4. String manipulation
-
-Do not use the strncpy function.  As mentioned in the man page, it does *not*
-guarantee a NULL-terminated buffer, which makes it extremely dangerous to use.
-It also zeros trailing destination bytes out to the specified length.  Instead,
-use this similar function when possible, but note its different signature:
-void pstrcpy(char *dest, int dest_buf_size, const char *src)
-
-Don't use strcat because it can't check for buffer overflows, but:
-char *pstrcat(char *buf, int buf_size, const char *s)
-
-The same limitation exists with sprintf and vsprintf, so use snprintf and
-vsnprintf.
-
-QEMU provides other useful string functions:
-int strstart(const char *str, const char *val, const char **ptr)
-int stristart(const char *str, const char *val, const char **ptr)
-int qemu_strnlen(const char *s, int max_len)
-
-There are also replacement character processing macros for isxyz and toxyz,
-so instead of e.g. isalnum you should use qemu_isalnum.
-
-Because of the memory management rules, you must use g_strdup/g_strndup
-instead of plain strdup/strndup.
-
-5. Printf-style functions
-
-Whenever you add a new printf-style function, i.e., one with a format
-string argument and following "..." in its prototype, be sure to use
-gcc's printf attribute directive in the prototype.
-
-This makes it so gcc's -Wformat and -Wformat-security options can do
-their jobs and cross-check format strings with the number and types
-of arguments.
-
-6. C standard, implementation defined and undefined behaviors
-
-C code in QEMU should be written to the C99 language specification. A copy
-of the final version of the C99 standard with corrigenda TC1, TC2, and TC3
-included, formatted as a draft, can be downloaded from:
- http://www.open-std.org/jtc1/sc22/WG14/www/docs/n1256.pdf
-
-The C language specification defines regions of undefined behavior and
-implementation defined behavior (to give compiler authors enough leeway to
-produce better code).  In general, code in QEMU should follow the language
-specification and avoid both undefined and implementation defined
-constructs. ("It works fine on the gcc I tested it with" is not a valid
-argument...) However there are a few areas where we allow ourselves to
-assume certain behaviors because in practice all the platforms we care about
-behave in the same way and writing strictly conformant code would be
-painful. These are:
- * you may assume that integers are 2s complement representation
- * you may assume that right shift of a signed integer duplicates
-   the sign bit (ie it is an arithmetic shift, not a logical shift)

 QEMU Maintainers
 ================

-The intention of this file is not to establish who owns what portions of the
-code base, but to provide a set of names that developers can consult when they
-have a question about a particular subset and also to provide a set of names
-to be CC'd when submitting a patch to obtain appropriate review.
-
-In general, if you have a question about inclusion of a patch, you should
-consult qemu-devel and not any specific individual privately.
-
-Descriptions of section entries:
-
-	M: Mail patches to: FullName <address@domain>
-	L: Mailing list that is relevant to this area
-	W: Web-page with status/info
-	Q: Patchwork web based patch tracking system site
-	T: SCM tree type and location.  Type is one of: git, hg, quilt, stgit.
-	S: Status, one of the following:
-	   Supported:	Someone is actually paid to look after this.
-	   Maintained:	Someone actually looks after it.
-	   Odd Fixes:	It has a maintainer but they don't have time to do
-			much other than throw the odd patch in. See below.
-	   Orphan:	No current maintainer [but maybe you could take the
-			role as you write your new code].
-	   Obsolete:	Old code. Something tagged obsolete generally means
-			it has been replaced by a better system and you
-			should be using that.
-	F: Files and directories with wildcard patterns.
-	   A trailing slash includes all files and subdirectory files.
-	   F:	drivers/net/	all files in and below drivers/net
-	   F:	drivers/net/*	all files in drivers/net, but not below
-	   F:	*/net/*		all files in "any top level directory"/net
-	   One pattern per line.  Multiple F: lines acceptable.
-	X: Files and directories that are NOT maintained, same rules as F:
-	   Files exclusions are tested before file matches.
-	   Can be useful for excluding a specific subdirectory, for instance:
-	   F:	net/
-	   X:	net/ipv6/
-	   matches all files in and below net excluding net/ipv6/
-	K: Keyword perl extended regex pattern to match content in a
-	   patch or file.  For instance:
-	   K: of_get_profile
-	      matches patches or files that contain "of_get_profile"
-	   K: \b(printk|pr_(info|err))\b
-	      matches patches or files that contain one or more of the words
-	      printk, pr_info or pr_err
-	   One regex pattern per line.  Multiple K: lines acceptable.

-                          QEMU Monitor Protocol
-                          =====================
-
-Introduction
-------------
-
-The QEMU Monitor Protocol (QMP) allows applications to communicate with
-QEMU's Monitor.
-
-QMP is JSON[1] based and currently has the following features:
-
- Lightweight, text-based, easy to parse data format
- Asynchronous messages support (ie. events)
- Capabilities Negotiation
-
-For detailed information on QMP's usage, please, refer to the following files:
-
-o qmp-spec.txt      QEMU Monitor Protocol current specification
-o qmp-commands.txt  QMP supported commands (auto-generated at build-time)
-o qmp-events.txt    List of available asynchronous events
-
-There is also a simple Python script called 'qmp-shell' available.
-
-IMPORTANT: It's strongly recommended to read the 'Stability Considerations'
-section in the qmp-commands.txt file before making any serious use of QMP.
-
-
-[1] http://www.json.org
-
-Usage
-----
-
-To enable QMP, you need a QEMU monitor instance in "control mode". There are
-two ways of doing this.
-
-The simplest one is using the '-qmp' command-line option. The following
-example makes QMP available on localhost port 4444:
-
-  $ qemu [...] -qmp tcp:localhost:4444,server
-
-However, in order to have more complex combinations, like multiple monitors,
-the '-mon' command-line option should be used along with the '-chardev' one.
-For instance, the following example creates one user monitor on stdio and one
-QMP monitor on localhost port 4444.
-
-   $ qemu [...] -chardev stdio,id=mon0 -mon chardev=mon0,mode=readline \
-                -chardev socket,id=mon1,host=localhost,port=4444,server \
-                -mon chardev=mon1,mode=control
-
-Please, refer to QEMU's manpage for more information.
-
-Simple Testing
--------------
-
-To manually test QMP one can connect with telnet and issue commands by hand:
-
-$ telnet localhost 4444
-Trying 127.0.0.1...
-Connected to localhost.
-Escape character is '^]'.
-{"QMP": {"version": {"qemu": {"micro": 50, "minor": 13, "major": 0}, "package": ""}, "capabilities": []}}
-{ "execute": "qmp_capabilities" }
-{"return": {}}
-{ "execute": "query-version" }
-{"return": {"qemu": {"micro": 50, "minor": 13, "major": 0}, "package": ""}}
-
-Development Process
-------------------
-
-When changing QMP's interface (by adding new commands, events or modifying
-existing ones) it's mandatory to update the relevant documentation, which is
-one (or more) of the files listed in the 'Introduction' section*.
-
-Also, it's strongly recommended to send the documentation patch first, before
-doing any code change. This is so because:
-
-  1. Avoids the code dictating the interface
-
-  2. Review can improve your interface.  Letting that happen before
-     you implement it can save you work.
-
-* The qmp-commands.txt file is generated from the qmp-commands.hx one, which
-  is the file that should be edited.

-{ "event": "WATCHDOG",
-     "data": { "action": "reset" },
-     "timestamp": { "seconds": 1267061043, "microseconds": 959568 } }
-
-Note: If action is "reset", "shutdown", or "pause" the WATCHDOG event is
-followed respectively by the RESET, SHUTDOWN, or STOP events.
-
-GUEST_PANICKED
--------------
-
-Emitted when guest OS panic is detected.
-
-Data:
-
- "action": Action that has been taken (json-string, currently always "pause").
-
-Example:
-
-{ "event": "GUEST_PANICKED",
-     "data": { "action": "pause" } }

-           QEMU Monitor Protocol Specification - Version 0.1
-
-1. Introduction
-===============
-
-This document specifies the QEMU Monitor Protocol (QMP), a JSON-based protocol
-which is available for applications to control QEMU at the machine-level.
-
-To enable QMP support, QEMU has to be run in "control mode". This is done by
-starting QEMU with the appropriate command-line options. Please, refer to the
-QEMU manual page for more information.
-
-2. Protocol Specification
-=========================
-
-This section details the protocol format. For the purpose of this document
-"Client" is any application which is communicating with QEMU in control mode,
-and "Server" is QEMU itself.
-
-JSON data structures, when mentioned in this document, are always in the
-following format:
-
-    json-DATA-STRUCTURE-NAME
-
-Where DATA-STRUCTURE-NAME is any valid JSON data structure, as defined by
-the JSON standard:
-
-http://www.ietf.org/rfc/rfc4627.txt
-
-For convenience, json-object members and json-array elements mentioned in
-this document will be in a certain order. However, in real protocol usage
-they can be in ANY order, thus no particular order should be assumed.
-
-2.1 General Definitions
-----------------------
-
-2.1.1 All interactions transmitted by the Server are json-objects, always
-      terminating with CRLF
-
-2.1.2 All json-objects members are mandatory when not specified otherwise
-
-2.2 Server Greeting
-------------------
-
-Right when connected the Server will issue a greeting message, which signals
-that the connection has been successfully established and that the Server is
-ready for capabilities negotiation (for more information refer to section
-'4. Capabilities Negotiation').
-
-The format is:
-
-{ "QMP": { "version": json-object, "capabilities": json-array } }
-
- Where,
-
- The "version" member contains the Server's version information (the format
-  is the same of the 'query-version' command)
- The "capabilities" member specify the availability of features beyond the
-  baseline specification
-
-2.3 Issuing Commands
--------------------
-
-The format for command execution is:
-
-{ "execute": json-string, "arguments": json-object, "id": json-value }
-
- Where,
-
- The "execute" member identifies the command to be executed by the Server
- The "arguments" member is used to pass any arguments required for the
-  execution of the command, it is optional when no arguments are required
- The "id" member is a transaction identification associated with the
-  command execution, it is optional and will be part of the response if
-  provided
-
-2.4 Commands Responses
----------------------
-
-There are two possible responses which the Server will issue as the result
-of a command execution: success or error.
-
-2.4.1 success
-------------
-
-The success response is issued when the command execution has finished
-without errors.
-
-The format is:
-
-{ "return": json-object, "id": json-value }
-
- Where,
-
- The "return" member contains the command returned data, which is defined
-  in a per-command basis or an empty json-object if the command does not
-  return data
- The "id" member contains the transaction identification associated
-  with the command execution (if issued by the Client)
-
-2.4.2 error
-----------
-
-The error response is issued when the command execution could not be
-completed because of an error condition.
-
-The format is:
-
-{ "error": { "class": json-string, "desc": json-string }, "id": json-value }
-
- Where,
-
- The "class" member contains the error class name (eg. "GenericError")
- The "desc" member is a human-readable error message. Clients should
-  not attempt to parse this message.
- The "id" member contains the transaction identification associated with
-  the command execution (if issued by the Client)
-
-NOTE: Some errors can occur before the Server is able to read the "id" member,
-in these cases the "id" member will not be part of the error response, even
-if provided by the client.
-
-2.5 Asynchronous events
-----------------------
-
-As a result of state changes, the Server may send messages unilaterally
-to the Client at any time. They are called 'asynchronous events'.
-
-The format is:
-
-{ "event": json-string, "data": json-object,
-  "timestamp": { "seconds": json-number, "microseconds": json-number } }
-
- Where,
-
- The "event" member contains the event's name
- The "data" member contains event specific data, which is defined in a
-  per-event basis, it is optional
- The "timestamp" member contains the exact time of when the event occurred
-  in the Server. It is a fixed json-object with time in seconds and
-  microseconds
-
-For a listing of supported asynchronous events, please, refer to the
-qmp-events.txt file.
-
-3. QMP Examples
-===============
-
-This section provides some examples of real QMP usage, in all of them
-'C' stands for 'Client' and 'S' stands for 'Server'.
-
-3.1 Server greeting
-------------------
-
-S: {"QMP": {"version": {"qemu": "0.12.50", "package": ""}, "capabilities": []}}
-
-3.2 Simple 'stop' execution
---------------------------
-
-C: { "execute": "stop" }
-S: {"return": {}}
-
-3.3 KVM information
-------------------
-
-C: { "execute": "query-kvm", "id": "example" }
-S: {"return": {"enabled": true, "present": true}, "id": "example"}
-
-3.4 Parsing error
------------------
-
-C: { "execute": }
-S: {"error": {"class": "GenericError", "desc": "Invalid JSON syntax" } }
-
-3.5 Powerdown event
-------------------
-
-S: {"timestamp": {"seconds": 1258551470, "microseconds": 802384}, "event":
-"POWERDOWN"}
-
-4. Capabilities Negotiation
----------------------------
-
-When a Client successfully establishes a connection, the Server is in
-Capabilities Negotiation mode.
-
-In this mode only the 'qmp_capabilities' command is allowed to run, all
-other commands will return the CommandNotFound error. Asynchronous messages
-are not delivered either.
-
-Clients should use the 'qmp_capabilities' command to enable capabilities
-advertised in the Server's greeting (section '2.2 Server Greeting') they
-support.
-
-When the 'qmp_capabilities' command is issued, and if it does not return an
-error, the Server enters in Command mode where capabilities changes take
-effect, all commands (except 'qmp_capabilities') are allowed and asynchronous
-messages are delivered.
-
-5 Compatibility Considerations
------------------------------
-
-All protocol changes or new features which modify the protocol format in an
-incompatible way are disabled by default and will be advertised by the
-capabilities array (section '2.2 Server Greeting'). Thus, Clients can check
-that array and enable the capabilities they support.
-
-The QMP Server performs a type check on the arguments to a command.  It
-generates an error if a value does not have the expected type for its
-key, or if it does not understand a key that the Client included.  The
-strictness of the Server catches wrong assumptions of Clients about
-the Server's schema.  Clients can assume that, when such validation
-errors occur, they will be reported before the command generated any
-side effect.
-
-However, Clients must not assume any particular:
-
- Length of json-arrays
- Size of json-objects; in particular, future versions of QEMU may add
-  new keys and Clients should be able to ignore them.
- Order of json-object members or json-array elements
- Amount of errors generated by a command, that is, new errors can be added
-  to any existing command in newer versions of the Server
-
-Of course, the Server does guarantee to send valid JSON.  But apart from
-this, a Client should be "conservative in what they send, and liberal in
-what they accept".
-
-6. Downstream extension of QMP
------------------------------
-
-We recommend that downstream consumers of QEMU do *not* modify QMP.
-Management tools should be able to support both upstream and downstream
-versions of QMP without special logic, and downstream extensions are
-inherently at odds with that.
-
-However, we recognize that it is sometimes impossible for downstreams to
-avoid modifying QMP.  Both upstream and downstream need to take care to
-preserve long-term compatibility and interoperability.
-
-To help with that, QMP reserves JSON object member names beginning with
-'__' (double underscore) for downstream use ("downstream names").  This
-means upstream will never use any downstream names for its commands,
-arguments, errors, asynchronous events, and so forth.
-
-Any new names downstream wishes to add must begin with '__'.  To
-ensure compatibility with other downstreams, it is strongly
-recommended that you prefix your downstram names with '__RFQDN_' where
-RFQDN is a valid, reverse fully qualified domain name which you
-control.  For example, a qemu-kvm specific monitor command would be:
-
-    (qemu) __org.linux-kvm_enable_irqchip
-
-Downstream must not change the server greeting (section 2.2) other than
-to offer additional capabilities.  But see below for why even that is
-discouraged.
-
-Section '5 Compatibility Considerations' applies to downstream as well
-as to upstream, obviously.  It follows that downstream must behave
-exactly like upstream for any input not containing members with
-downstream names ("downstream members"), except it may add members
-with downstream names to its output.
-
-Thus, a client should not be able to distinguish downstream from
-upstream as long as it doesn't send input with downstream members, and
-properly ignores any downstream members in the output it receives.
-
-Advice on downstream modifications:
-
-1. Introducing new commands is okay.  If you want to extend an existing
-   command, consider introducing a new one with the new behaviour
-   instead.
-
-2. Introducing new asynchronous messages is okay.  If you want to extend
-   an existing message, consider adding a new one instead.
-
-3. Introducing new errors for use in new commands is okay.  Adding new
-   errors to existing commands counts as extension, so 1. applies.
-
-4. New capabilities are strongly discouraged.  Capabilities are for
-   evolving the basic protocol, and multiple diverging basic protocol
-   dialects are most undesirable.

+- cycle counter for all archs
+- cpu_interrupt() win32/SMP fix
+- merge PIC spurious interrupt patch
+- warning for OS/2: must not use 128 MB memory (merge bochs cmos patch ?)
+- config file (at least for windows/Mac OS X)
+- update doc: PCI infos.
+- basic VGA optimizations
+- better code fetch
+- do not resize vga if invalid size.
+- TLB code protection support for PPC
+- disable SMC handling for ARM/SPARC/PPC (not finished)
+- see undefined flags for BTx insn
+- keyboard output buffer filling timing emulation
+- tests for each target CPU
+- fix all remaining thread lock issues (must put TBs in a specific invalid

+
+ppc specific:
+------------
+- TLB invalidate not needed if msr_pr changes
+- enable shift optimizations ?
+
+linux-user specific:
+-------------------
+- remove threading support as it cannot work at this point
+- improve IPC syscalls
+- more syscalls (in particular all 64 bit ones, IPCs, fix 64 bit

- * file=gluster[+transport]://[server[:port]]/volname/image[?socket=...]
- *
- * 'gluster' is the protocol.
- *
- * 'transport' specifies the transport type used to connect to gluster
- * management daemon (glusterd). Valid transport types are
- * tcp, unix and rdma. If a transport type isn't specified, then tcp
- * type is assumed.
- *
- * 'server' specifies the server where the volume file specification for
- * the given volume resides. This can be either hostname, ipv4 address
- * or ipv6 address. ipv6 address needs to be within square brackets [ ].
- * If transport type is 'unix', then 'server' field should not be specifed.
- * The 'socket' field needs to be populated with the path to unix domain
- * socket.
- *
- * 'port' is the port number on which glusterd is listening. This is optional
- * and if not specified, QEMU will send 0 which will make gluster to use the
- * default port. If the transport type is unix, then 'port' should not be
- * specified.
- *
- * 'volname' is the name of the gluster volume which contains the VM image.
- *
- * 'image' is the path to the actual VM image that resides on gluster volume.
- *
- * Examples:
- *
- * file=gluster://1.2.3.4/testvol/a.img
- * file=gluster+tcp://1.2.3.4/testvol/a.img
- * file=gluster+tcp://1.2.3.4:24007/testvol/dir/a.img
- * file=gluster+tcp://[1:2:3:4:5:6:7:8]/testvol/dir/a.img
- * file=gluster+tcp://[1:2:3:4:5:6:7:8]:24007/testvol/dir/a.img
- * file=gluster+tcp://server.domain.com:24007/testvol/dir/a.img
- * file=gluster+unix:///testvol/dir/a.img?socket=/tmp/glusterd.socket

- * again later during request processing.  If request->l2_table is non-NULL it
- * will be unreferenced before taking on the new cache entry.
