Fabiano Rosas	405e352d28	migration/multifd: Fix p->iov leak in multifd-uadk.c The send_cleanup() hook should free the p->iov that was allocated at send_setup(). This was missed because the UADK code is conditional on the presence of the accelerator, so it's not tested by default.

Fabiano Rosas	308d165c77	migration/multifd: Make MultiFDMethods const The methods are defined at module_init time and don't ever change. Make them const.

Fabiano Rosas	6f848dac4a	migration/multifd: Standardize on multifd ops names Add the multifd_ prefix to all functions and remove the useless docstrings. Reviewed-by: Peter Xu <peterx@redhat.com> Signed-off-by: Fabiano Rosas <farosas@suse.de>	2 years ago
Fabiano Rosas	9f0e108901	migration/multifd: Replace p->pages with an union pointer We want multifd to be able to handle more types of data than just ram pages. To start decoupling multifd from pages, replace p->pages (MultiFDPages_t) with the new type MultiFDSendData that hides the client payload inside an union. The general idea here is to isolate functions that need to handle MultiFDPages_t and move them in the future to multifd-ram.c, while multifd.c will stay with only the core functions that handle MultiFDSendData/MultiFDRecvData.

Fabiano Rosas	90fa121c6c	migration/multifd: Inline page_size and page_count The MultiFD*Params structures are for per-channel data. Constant values should not be there because that needlessly wastes cycles and storage. The page_size and page_count fall into this category so move them inline in multifd.h.

Fabiano Rosas	bc112a6c90	migration/multifd: Reduce access to p->pages I'm about to replace the p->pages pointer with an opaque pointer, so do a cleanup now to reduce direct accesses to p->page, which makes the next diffs cleaner.

Shameer Kolothum	c1dfd12168	migration/multifd: Switch to no compression when no hardware support Send raw packets over if UADK hardware support is not available. This is to satisfy Qemu qtest CI which may run on platforms that don't have UADK hardware support. Subsequent patch will add support for uadk migration qtest.
