ram_save_block is getting a bit too complicated, and does two separate things: 1) Finds a page to send 2) Sends the page (dealing with compression etc) Split into 'ram_save_page' to send the page and deal with compression (2) Rename remaining function to 'ram_find_and_save_block' Signed-off-by: Dr. David Alan Gilbert <dgilbert@redhat.com> Signed-off-by: Juan Quintela <quintela@redhat.com>
2014-05-14arch_init: Simplify code for load_xbzrle()Chen Gang
For xbzrle_decode_buffer(), when decoding contents will exceed writing buffer, it will return -1, so need not check the return value whether large than writing buffer. And when failure occurs within load_xbzrle(), it always return -1 without any resources which need release.

2014-05-05Count used RAMBlock pages for migration_dirty_pagesDr. David Alan Gilbert
This is a fix for a bug* triggered by a migration after hot unplugging a few virtio-net NICs, that caused migration never to converge, because 'migration_dirty_pages' is incorrectly initialised. 'migration_dirty_pages' is used as a tally of the number of outstanding dirty pages, to give the migration code an idea of how much more data will need to be transferred, and thus whether it can end the iterative phase. It was initialised to the total size of the RAMBlock address space, however hotunplug can leave this space sparse, and hence migration_dirty_pages ended up too large.

2013-11-19migration: drop MADVISE_DONT_NEED for incoming zero pagesPeter Lieven
The madvise for zeroed out pages was introduced when every transferred zero page was memset to zero and thus allocated. Since commit 211ea740 we check for zeroness of a target page before we memset it to zero. Additionally we memmap target memory so it is essentially zero initialized (except for e.g. option roms and bios which are loaded into target memory although they shouldn't). It was reported recently that this madvise causes a performance degradation in some situations. As the madvise should only be called rarely and if it's called it is likely on a busy page (it was non-zero and changed to zero during migration) drop it completely.

2013-09-28smbios: Make multiple -smbios type= accumulate sanelyMarkus Armbruster
Currently, -smbios type=T,NAME=VAL,... adds one field (T,NAME) with value VAL to fw_cfg for each unique NAME. If NAME occurs multiple times, the last one's VAL is used (before the QemuOpts conversion, the first one was used). Multiple -smbios can add multiple fields with the same (T, NAME). SeaBIOS reads all of them from fw_cfg, but uses only the first field (T, NAME). The others are ignored. "First one wins, subsequent ones get ignored silently" isn't nice. We commonly let the last option win. Useful, because it lets you -readconfig first, then selectively override with command line options. Clean up -smbios to work the common way. Accumulate the settings, with later ones overwriting earlier ones. Put the result into fw_cfg (no more useless duplicates). Bonus cleanup: qemu_uuid_parse() no longer sets SMBIOS system uuid by side effect.

2013-08-21arch_init: align MR size to target page sizeMichael S. Tsirkin
Migration code assumes that each MR is a multiple of TARGET_PAGE_SIZE: MR size is divided by TARGET_PAGE_SIZE, so if it isn't migration never completes. But this isn't really required for regions set up with memory_region_init_ram, since that calls qemu_ram_alloc which aligns size up using TARGET_PAGE_ALIGN. Align MR size up to full target page sizes, this way migration completes even if we create a RAM MR which is not a full target page size. Signed-off-by: Michael S.
