Hi This includes ram_save_live split + XBZRE changes.
Changes for the previous posts of this series: ram_save_split: - recalculate expected_time (Igor). - Use PRIu64 consistently everywhere XBZRE: - rebased on top of previous series - remove stage3 optimization, now XBZRE don't know about stages (code is much simpler) - reintroduce the stage3(complete) optimization. We now sent the page compressed if the page is on the cache, otherwise, we sent the page uncompressed without putting it on the cache. This is better than the previous optimization. Please review, Juan. Juan Quintela (13): savevm: Use a struct to pass all handlers savevm: Live migration handlers register the struct directly savevm: remove SaveSetParamsHandler savevm: remove SaveLiveStateHandler savevm: Refactor cancel operation in its own operation savevm: introduce is_active method savevm: split save_live_setup from save_live_state savevm: split save_live into stage2 and stage3 ram: save_live_setup() don't need to sent pages ram: save_live_complete() only do one loop ram: iterate phase ram: save_live_setup() we don't need to synchronize the dirty bitmap. ram: save live optimization Orit Wasserman (9): Add migration capabilities Add XBZRLE documentation Add cache handling functions Add uleb encoding/decoding functions Change ram_save_block to return -1 if there are no more changes Add xbzrle_encode_buffer and xbzrle_decode_buffer functions Add XBZRLE to ram_save_block and ram_save_live Add migrate_set_cachesize command Add XBZRLE statistics Makefile.objs | 1 + arch_init.c | 380 +++++++++++++++++++++++++++++++++++++++------ block-migration.c | 153 +++++++++++------- cutils.c | 42 +++++ docs/xbzrle.txt | 136 ++++++++++++++++ hmp-commands.hx | 36 +++++ hmp.c | 90 +++++++++++ hmp.h | 3 + include/qemu/page_cache.h | 79 ++++++++++ migration.c | 159 ++++++++++++++++++- migration.h | 25 ++- monitor.c | 7 + page_cache.c | 216 ++++++++++++++++++++++++++ qapi-schema.json | 102 +++++++++++- qemu-common.h | 21 +++ qmp-commands.hx | 127 ++++++++++++++- savevm.c | 236 +++++++++++++++++++++++----- vl.c | 3 +- vmstate.h | 18 ++- 19 files changed, 1676 insertions(+), 158 deletions(-) create mode 100644 docs/xbzrle.txt create mode 100644 include/qemu/page_cache.h create mode 100644 page_cache.c -- 1.7.10.4
