2016-05-26migration: delete QEMUFile stdio implementationDaniel P. Berrange
Now that the exec migration backend and savevm have converted to use the QIOChannel based QEMUFile, there is no user remaining for the stdio based QEMUFile impl and it can be deleted.

2016-01-29migration: Clean up includesPeter Maydell
Clean up includes so that osdep.h is included first and headers which it implies are not included manually. This commit was created with scripts/clean-includes. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 1453832250-766-2-git-send-email-peter.maydell@linaro.org
2015-10-20coroutine: move into libqemuutil.a libraryDaniel P. Berrange
The coroutine files are currently referenced by the block-obj-y variable. The coroutine functionality though is already used by more than just the block code. eg migration code uses coroutine yield. In the future the I/O channel code will also use the coroutine yield functionality. Since the coroutine code is nicely self-contained it can be easily built as part of the libqemuutil.a library, making it widely available. The headers are also moved into include/qemu, instead of the include/block directory, since they are now part of the util codebase, and the impl was never in the block/ directory either.

2015-09-29migration: Use g_new() & friends where that makes obvious senseMarkus Armbruster
g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer, for two reasons. One, it catches multiplication overflowing size_t. Two, it returns T * rather than void *, which lets the compiler catch more type errors. This commit only touches allocations with size arguments of the form sizeof(T). Same Coccinelle semantic patch as in commit b45c03f.

2015-09-29migration: size_t'ify some of qemu-fileDr. David Alan Gilbert
This is a start on using size_t more in qemu-file and friends; it fixes up QEMUFilePutBufferFunc and QEMUFileGetBufferFunc to take size_t lengths and return ssize_t return values (like read(2)) and fixes up all the different implementations of them. Note that I've not yet followed this deeply into bdrv_ implementations.

2014-12-16Start migrating migration code into a migration directoryDr. David Alan Gilbert
The migration code now occupies a fair chunk of the top level .c files, it seems time to give it it's own directory. I've not touched: arch_init.c - that's mostly RAM migration but has a few random other bits savevm.c - because it's built target specific This is purely a code move; no code has changed. - it fails checkpatch because of old violations, it feels safer to keep this as purely a move and fix those at some mythical future date. The xbzrle and vmstate tests are now only run for softmmu builds since they require files in the migrate/ directory which is only built for softmmu.
