| QEMU Coding Style | ||||
| ================= | ||||
|  | ||||
| Please use the script checkpatch.pl in the scripts directory to check | ||||
| patches before submitting. | ||||
|  | ||||
| 1. Whitespace | ||||
|  | ||||
| Of course, the most important aspect in any coding style is whitespace. | ||||
| Crusty old coders who have trouble spotting the glasses on their noses | ||||
| can tell the difference between a tab and eight spaces from a distance | ||||
| of approximately fifteen parsecs.  Many a flamewar have been fought and | ||||
| lost on this issue. | ||||
|  | ||||
| QEMU indents are four spaces.  Tabs are never used, except in Makefiles | ||||
| where they have been irreversibly coded into the syntax. | ||||
| Spaces of course are superior to tabs because: | ||||
|  | ||||
|  - You have just one way to specify whitespace, not two.  Ambiguity breeds | ||||
|    mistakes. | ||||
|  - The confusion surrounding 'use tabs to indent, spaces to justify' is gone. | ||||
|  - Tab indents push your code to the right, making your screen seriously | ||||
|    unbalanced. | ||||
|  - Tabs will be rendered incorrectly on editors who are misconfigured not | ||||
|    to use tab stops of eight positions. | ||||
|  - Tabs are rendered badly in patches, causing off-by-one errors in almost | ||||
|    every line. | ||||
|  - It is the QEMU coding style. | ||||
|  | ||||
| Do not leave whitespace dangling off the ends of lines. | ||||
|  | ||||
| 2. Line width | ||||
|  | ||||
| Lines should be 80 characters; try not to make them longer. | ||||
|  | ||||
| Sometimes it is hard to do, especially when dealing with QEMU subsystems | ||||
| that use long function or symbol names.  Even in that case, do not make | ||||
| lines much longer than 80 characters. | ||||
|  | ||||
| Rationale: | ||||
|  - Some people like to tile their 24" screens with a 6x4 matrix of 80x24 | ||||
|    xterms and use vi in all of them.  The best way to punish them is to | ||||
|    let them keep doing it. | ||||
|  - Code and especially patches is much more readable if limited to a sane | ||||
|    line length.  Eighty is traditional. | ||||
|  - The four-space indentation makes the most common excuse ("But look | ||||
|    at all that white space on the left!") moot. | ||||
|  - It is the QEMU coding style. | ||||
|  | ||||
| 3. Naming | ||||
|  | ||||
| Variables are lower_case_with_underscores; easy to type and read.  Structured | ||||
| type names are in CamelCase; harder to type but standing out.  Enum type | ||||
| names and function type names should also be in CamelCase.  Scalar type | ||||
| names are lower_case_with_underscores_ending_with_a_t, like the POSIX | ||||
| uint64_t and family.  Note that this last convention contradicts POSIX | ||||
| and is therefore likely to be changed. | ||||
|  | ||||
| When wrapping standard library functions, use the prefix qemu_ to alert | ||||
| readers that they are seeing a wrapped version; otherwise avoid this prefix. | ||||
|  | ||||
| 4. Block structure | ||||
|  | ||||
| Every indented statement is braced; even if the block contains just one | ||||
| statement.  The opening brace is on the line that contains the control | ||||
| flow statement that introduces the new block; the closing brace is on the | ||||
| same line as the else keyword, or on a line by itself if there is no else | ||||
| keyword.  Example: | ||||
|  | ||||
|     if (a == 5) { | ||||
|         printf("a was 5.\n"); | ||||
|     } else if (a == 6) { | ||||
|         printf("a was 6.\n"); | ||||
|     } else { | ||||
|         printf("a was something else entirely.\n"); | ||||
|     } | ||||
|  | ||||
| Note that 'else if' is considered a single statement; otherwise a long if/ | ||||
| else if/else if/.../else sequence would need an indent for every else | ||||
| statement. | ||||
|  | ||||
| An exception is the opening brace for a function; for reasons of tradition | ||||
| and clarity it comes on a line by itself: | ||||
|  | ||||
|     void a_function(void) | ||||
|     { | ||||
|         do_something(); | ||||
|     } | ||||
|  | ||||
| Rationale: a consistent (except for functions...) bracing style reduces | ||||
| ambiguity and avoids needless churn when lines are added or removed. | ||||
| Furthermore, it is the QEMU coding style. | ||||
|  | ||||
| 5. Declarations | ||||
|  | ||||
| Mixed declarations (interleaving statements and declarations within | ||||
| blocks) are generally not allowed; declarations should be at the beginning | ||||
| of blocks. | ||||
|  | ||||
| Every now and then, an exception is made for declarations inside a | ||||
| #ifdef or #ifndef block: if the code looks nicer, such declarations can | ||||
| be placed at the top of the block even if there are statements above. | ||||
| On the other hand, however, it's often best to move that #ifdef/#ifndef | ||||
| block to a separate function altogether. | ||||
|  | ||||
| 6. Conditional statements | ||||
|  | ||||
| When comparing a variable for (in)equality with a constant, list the | ||||
| constant on the right, as in: | ||||
|  | ||||
| if (a == 1) { | ||||
|     /* Reads like: "If a equals 1" */ | ||||
|     do_something(); | ||||
| } | ||||
|  | ||||
| Rationale: Yoda conditions (as in 'if (1 == a)') are awkward to read. | ||||
| Besides, good compilers already warn users when '==' is mis-typed as '=', | ||||
| even when the constant is on the right. | ||||

| 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. | ||||
|  | ||||
| For CPU virtual addresses there are several possible types. | ||||
| vaddr is the best type to use to hold a CPU virtual address in | ||||
| target-independent code. It is guaranteed to be large enough to hold a | ||||
| virtual address for any target, and it does not change size from target | ||||
| to target. It is always unsigned. | ||||
| target_ulong is a type the size of a virtual address on the CPU; this means | ||||
| it may be 32 or 64 bits depending on which target is being built. It should | ||||
| therefore be used only in target-specific code, and in some | ||||
| performance-critical built-per-target core code such as the TLB code. | ||||
| There is also a signed version, target_long. | ||||
| abi_ulong is for the *-user targets, and represents a type the size of | ||||
| 'void *' in that target's ABI. (This may not be the same as the size of a | ||||
| full CPU virtual address in the case of target ABIs which use 32 bit pointers | ||||
| on 64 bit CPUs, like sparc32plus.) Definitions of structures that must match | ||||
| the target's ABI must use this type for anything that on the target is defined | ||||
| to be an 'unsigned long' or a pointer type. | ||||
| There is also a signed version, abi_long. | ||||
|  | ||||
| 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) | ||||
|  | ||||
| In addition, QEMU assumes that the compiler does not use the latitude | ||||
| given in C99 and C11 to treat aspects of signed '<<' as undefined, as | ||||
| documented in the GNU Compiler Collection manual starting at version 4.0. | ||||
|  | ||||
| 7. Error handling and reporting | ||||
|  | ||||
| 7.1 Reporting errors to the human user | ||||
|  | ||||
| Do not use printf(), fprintf() or monitor_printf().  Instead, use | ||||
| error_report() or error_vreport() from error-report.h.  This ensures the | ||||
| error is reported in the right place (current monitor or stderr), and in | ||||
| a uniform format. | ||||
|  | ||||
| Use error_printf() & friends to print additional information. | ||||
|  | ||||
| error_report() prints the current location.  In certain common cases | ||||
| like command line parsing, the current location is tracked | ||||
| automatically.  To manipulate it manually, use the loc_*() from | ||||
| error-report.h. | ||||
|  | ||||
| 7.2 Propagating errors | ||||
|  | ||||
| An error can't always be reported to the user right where it's detected, | ||||
| but often needs to be propagated up the call chain to a place that can | ||||
| handle it.  This can be done in various ways. | ||||
|  | ||||
| The most flexible one is Error objects.  See error.h for usage | ||||
| information. | ||||
|  | ||||
| Use the simplest suitable method to communicate success / failure to | ||||
| callers.  Stick to common methods: non-negative on success / -1 on | ||||
| error, non-negative / -errno, non-null / null, or Error objects. | ||||
|  | ||||
| Example: when a function returns a non-null pointer on success, and it | ||||
| can fail only in one way (as far as the caller is concerned), returning | ||||
| null on failure is just fine, and certainly simpler and a lot easier on | ||||
| the eyes than propagating an Error object through an Error ** parameter. | ||||
|  | ||||
| Example: when a function's callers need to report details on failure | ||||
| only the function really knows, use Error **, and set suitable errors. | ||||
|  | ||||
| Do not report an error to the user when you're also returning an error | ||||
| for somebody else to handle.  Leave the reporting to the place that | ||||
| consumes the error returned. | ||||
|  | ||||
| 7.3 Handling errors | ||||
|  | ||||
| Calling exit() is fine when handling configuration errors during | ||||
| startup.  It's problematic during normal operation.  In particular, | ||||
| monitor commands should never exit(). | ||||
|  | ||||
| Do not call exit() or abort() to handle an error that can be triggered | ||||
| by the guest (e.g., some unimplemented corner case in guest code | ||||
| translation or device emulation).  Guests should not be able to | ||||
| terminate QEMU. | ||||
|  | ||||
| Note that &error_fatal is just another way to exit(1), and &error_abort | ||||
| is just another way to abort(). | ||||

|          =========== | ||||
| The QEMU x86 emulator | ||||
| --------------------- | ||||
|  | ||||
| QEMU is a generic and open source machine & userspace emulator and | ||||
| virtualizer. | ||||
| INSTALLATION | ||||
| ------------ | ||||
|  | ||||
| QEMU is capable of emulating a complete machine in software without any | ||||
| need for hardware virtualization support. By using dynamic translation, | ||||
| it achieves very good performance. QEMU can also integrate with the Xen | ||||
| and KVM hypervisors to provide emulated hardware while allowing the | ||||
| hypervisor to manage the CPU. With hypervisor support, QEMU can achieve | ||||
| near native performance for CPUs. When QEMU emulates CPUs directly it is | ||||
| capable of running operating systems made for one machine (e.g. an ARMv7 | ||||
| board) on a different machine (e.g. an x86_64 PC board). | ||||
| Type  | ||||
|  | ||||
| QEMU is also capable of providing userspace API virtualization for Linux | ||||
| and BSD kernel interfaces. This allows binaries compiled against one | ||||
| architecture ABI (e.g. the Linux PPC64 ABI) to be run on a host using a | ||||
| different architecture ABI (e.g. the Linux x86_64 ABI). This does not | ||||
| involve any hardware emulation, simply CPU and syscall emulation. | ||||
|     ./configure | ||||
|     make | ||||
|  | ||||
| QEMU aims to fit into a variety of use cases. It can be invoked directly | ||||
| by users wishing to have full control over its behaviour and settings. | ||||
| It also aims to facilitate integration into higher level management | ||||
| layers, by providing a stable command line interface and monitor API. | ||||
| It is commonly invoked indirectly via the libvirt library when using | ||||
| open source applications such as oVirt, OpenStack and virt-manager. | ||||
| to build qemu, qemu-CPU and libqemu.a (CPU is the name of the various | ||||
| supported target CPUs). | ||||
|  | ||||
| QEMU as a whole is released under the GNU General Public License, | ||||
| version 2. For full licensing details, consult the LICENSE file. | ||||
| Type | ||||

|     make install | ||||
|  | ||||
| to install QEMU in /usr/local | ||||
|  | ||||
| Tested tool versions | ||||
| -------------------- | ||||
|  | ||||
| In order to compile QEMU succesfully, it is very important that you | ||||
| have the right tools. The most important one is gcc. I cannot guaranty | ||||
| that QEMU works if you do not use a tested gcc version. Look at | ||||
| 'configure' and 'Makefile' if you want to make a different gcc | ||||
| version work. | ||||

|  | ||||
| [1] On Alpha, QEMU needs the gcc 'visibility' attribute only available | ||||
|     for gcc version >= 3.3. | ||||
| [2] Linux >= 2.4.20 is necessary for precise exception support | ||||
|     (untested). | ||||
| [3] 2.4.9-ac10-rmk2-np1-cerf2 | ||||
|  | ||||
| [4] gcc 2.95.x generates invalid code when using too many register | ||||
| variables. You must use gcc 3.x on PowerPC. | ||||

|  | ||||
| Read the documentation in qemu-doc.html. | ||||
|  | ||||
|  | ||||
| Building | ||||
| ======== | ||||
|  | ||||
| QEMU is multi-platform software intended to be buildable on all modern | ||||
| Linux platforms, OS-X, Win32 (via the Mingw64 toolchain) and a variety | ||||
| of other UNIX targets. The simple steps to build QEMU are: | ||||
|  | ||||
|   mkdir build | ||||
|   cd build | ||||
|   ../configure | ||||
|   make | ||||
|  | ||||
| Complete details of the process for building and configuring QEMU for | ||||
| all supported host platforms can be found in the qemu-tech.html file. | ||||
| Additional information can also be found online via the QEMU website: | ||||
|  | ||||
|   http://qemu-project.org/Hosts/Linux | ||||
|   http://qemu-project.org/Hosts/W32 | ||||
|  | ||||
|  | ||||
| Submitting patches | ||||
| ================== | ||||
|  | ||||
| The QEMU source code is maintained under the GIT version control system. | ||||
|  | ||||
|    git clone git://git.qemu-project.org/qemu.git | ||||
|  | ||||
| When submitting patches, the preferred approach is to use 'git | ||||
| format-patch' and/or 'git send-email' to format & send the mail to the | ||||
| qemu-devel@nongnu.org mailing list. All patches submitted must contain | ||||
| a 'Signed-off-by' line from the author. Patches should follow the | ||||
| guidelines set out in the HACKING and CODING_STYLE files. | ||||
|  | ||||
| Additional information on submitting patches can be found online via | ||||
| the QEMU website | ||||
|  | ||||
|   http://qemu-project.org/Contribute/SubmitAPatch | ||||
|   http://qemu-project.org/Contribute/TrivialPatches | ||||
|  | ||||
|  | ||||
| Bug reporting | ||||
| ============= | ||||
|  | ||||
| The QEMU project uses Launchpad as its primary upstream bug tracker. Bugs | ||||
| found when running code built from QEMU git or upstream released sources | ||||
| should be reported via: | ||||
|  | ||||
|   https://bugs.launchpad.net/qemu/ | ||||
|  | ||||
| If using QEMU via an operating system vendor pre-built binary package, it | ||||
| is preferable to report bugs to the vendor's own bug tracker first. If | ||||
| the bug is also known to affect latest upstream code, it can also be | ||||
| reported via launchpad. | ||||
|  | ||||
| For additional information on bug reporting consult: | ||||
|  | ||||
|   http://qemu-project.org/Contribute/ReportABug | ||||
|  | ||||
|  | ||||
| Contact | ||||
| ======= | ||||
|  | ||||
| The QEMU community can be contacted in a number of ways, with the two | ||||
| main methods being email and IRC | ||||
|  | ||||
|  - qemu-devel@nongnu.org | ||||
|    http://lists.nongnu.org/mailman/listinfo/qemu-devel | ||||
|  - #qemu on irc.oftc.net | ||||
|  | ||||
| Information on additional methods of contacting the community can be | ||||
| found online via the QEMU website: | ||||

| - more syscalls (in particular all 64 bit ones, IPCs, fix 64 bit | ||||
|   issues, fix 16 bit uid issues) | ||||
| - use page_unprotect_range in every suitable syscall to handle all | ||||
|   cases of self modifying code. | ||||
| - use gcc as a backend to generate better code (easy to do by using | ||||
|   op-i386.c operations as local inline functions). | ||||
