2016-08-11Update ancient copyright string in -version outputPeter Maydell
Currently the -version command line argument prints a string ending with "Copyright (c) 2003-2008 Fabrice Bellard". This is now some eight years out of date; abstract it out of the several places that print the string and update it to: Copyright (c) 2003-2016 Fabrice Bellard and the QEMU Project developers to reflect the work by all the QEMU Project contributors over the last decade.

2016-06-07qemu-common.h: Drop WORDS_ALIGNED definePeter Maydell
The WORDS_ALIGNED #define is not used anywhere, and hasn't been since 2013 when commit 612d590ebc6cef rewrote the various ld<type>_<endian>_p functions to not use it. Remove the #define and the comment describing it. Also remove the line in the comment about TARGET_WORDS_ALIGNED, since it has never actually existed.

2016-03-08cutils: add avx2 instruction optimizationLiang Li
buffer_find_nonzero_offset() is a hot function during live migration. Now it use SSE2 instructions for optimization. For platform supports AVX2 instructions, use AVX2 instructions for optimization can help to improve the performance of buffer_find_nonzero_offset() about 30% comparing to SSE2. Live migration can be faster with this optimization, the test result shows that for an 8GiB RAM idle guest just boots, this patch can help to shorten the total live migration time about 6%. This patch use the ifunc mechanism to select the proper function when running, for platform supports AVX2, execute the AVX2 instructions, else, execute the original instructions.

2015-10-16util - add automated ID generation utilityJeff Cody
Multiple sub-systems in QEMU may find it useful to generate IDs for objects that a user may reference via QMP or HMP. This patch presents a standardized way to do it, so that automatic ID generation follows the same rules. This patch enforces the following rules when generating an ID: 1.) Guarantee no collisions with a user-specified ID 2.) Identify the sub-system the ID belongs to 3.) Guarantee of uniqueness 4.) Spoiling predictability, to avoid creating an assumption of object ordering and parsing (i.e., we don't want users to think they can guess the next ID based on prior behavior). The scheme for this is as follows (no spaces): # subsys D RR Reserved char --| | | | Subsystem String ----| | | Unique number (64-bit) --| | Two-digit random number ---| For example, a generated node-name for the block sub-system may look like this: #block076 The caller of id_generate() is responsible for freeing the generated node name string with g_free().

2015-09-07Make pow2ceil() and pow2floor() inlinePeter Maydell
Since the pow2floor() function is now used in a hot code path, make it inline; for consistency, provide pow2ceil() as an inline function too. Because these functions use ctz64() we have to put the inline versions into host-utils.h, so they have access to ctz64(), and move the inline is_power_of_2() along with them. We then need to include host-utils.h from qemu-common.h so that the files which use these functions via qemu-common.h still have access to them.

2015-07-06Stop including qemu-common.h in memory.hPeter Maydell
Including qemu-common.h from other header files is generally a bad idea, because it means it's very easy to end up with a circular dependency. For instance, if we wanted to include memory.h from qom/cpu.h we'd end up with this loop: memory.h -> qemu-common.h -> cpu.h -> cpu-qom.h -> qom/cpu.h -> memory.h Remove the include from memory.h. This requires us to fix up a few other files which were inadvertently getting declarations indirectly through memory.h. The biggest change is splitting the fprintf_function typedef out into its own header so other headers can get at it without having to include qemu-common.h.

2014-11-02pidfile: stop making pidfile error a special caseMichael Tokarev
In case of -daemonize, we write non-zero to the daemon pipe only if pidfile creation failed, so the parent will report error about pidfile problem. There's no need to make special case for this, since all other errors are reported by the child just fine. Let the parent report error and simplify logic in os_daemonize(). This way, we don't need os_pidfile_error() function, since it only prints error now, so put the error reporting printf into the only place where qemu_create_pidfile() is called, in vl.c.

2014-10-03util: Emancipate id_wellformed() from QemuOptsMarkus Armbruster
IDs have long spread beyond QemuOpts: not everything with an ID necessarily goes through QemuOpts. Commit 9aebf3b is about such a case: block layer names are meant to be well-formed IDs, but some of them don't go through QemuOpts, and thus weren't checked. The commit fixed that the straightforward way: rename the internal QemuOpts helper id_wellformed() to qemu_opts_id_wellformed() and give it external linkage. Instead of using it directly in block.c, the commit adds wrapper bdrv_is_valid_name(), probably to hide the connection to QemuOpts. Go one logical step further: emancipate IDs from QemuOpts. Rename the function back to id_wellformed(), and put it in another file. While there, clean up its value to bool. Peel off the bdrv_is_valid_name() wrapper.

2014-07-14dma-helpers: Fix too long qiovKevin Wolf
If the size of the scatter/gather list isn't a multiple of 512, the number of sectors for the block layer request is rounded down, resulting in a qiov that doesn't match the request length. Truncate the qiov to the new length of the request. This fixes the IDE qtest case /x86_64/ide/bmdma/short_prdt.
