2021-02-08migration: Fix cache_init()'s "Failed to allocate" error messagesMarkus Armbruster
cache_init() attempts to handle allocation failure. The two error messages are garbage, as untested error messages commonly are: Parameter 'cache size' expects Failed to allocate cache Parameter 'cache size' expects Failed to allocate page cache Fix them to just Failed to allocate cache Failed to allocate page cache Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Dr. David Alan Gilbert <dgilbert@redhat.com> Message-Id: <20210202141734.2488076-4-armbru@redhat.com> Signed-off-by: Dr. David Alan Gilbert <dgilbert@redhat.com>
2021-02-08migration: Clean up signed vs. unsigned XBZRLE cache-sizeMarkus Armbruster
73af8dd8d7 "migration: Make xbzrle_cache_size a migration parameter" (v2.11.0) made the new parameter unsigned (QAPI type 'size', uint64_t in C). It neglected to update existing code, which continues to use int64_t. migrate_xbzrle_cache_size() returns the new parameter. Adjust its return type. QMP query-migrate-cache-size returns migrate_xbzrle_cache_size(). Adjust its return type. migrate-set-parameters passes the new parameter to xbzrle_cache_resize(). Adjust its parameter type. xbzrle_cache_resize() passes it on to cache_init(). Adjust its parameter type.

2018-06-01migration: use local path for local headersMichael S. Tsirkin
When pulling in headers that are in the same directory as the C file (as opposed to one in include/), we should use its relative path, without a directory. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Reviewed-by: Juan Quintela <quintela@redhat.com>
2017-10-29migration: Make sure that we pass the right cache sizeJuan Quintela
Instead of passing silently round down the number of pages, make it an error that the cache size is not a power of 2. Signed-off-by: Juan Quintela <quintela@redhat.com> Reviewed-by: Dr. David Alan Gilbert <dgilbert@redhat.com>
