This is an updated v6 patch series of the v5 series located here:
https://lore.kernel.org/qemu-devel/cover.1739994627.git.maciej.szmigi...@oracle.com/
What this patch set is about?
Current live migration device state transfer is done via the main
(single)
migration channel, which reduces performance and severally impacts the
migration downtime for VMs having large device state that needs to be
transferred during the switchover phase.
Example devices that have such large switchover phase device state
are some
types of VFIO SmartNICs and GPUs.
This patch set allows parallelizing this transfer by using multifd
channels
for it.
It also introduces new load and save threads per VFIO device for
decoupling
these operations from the main migration thread.
These threads run on newly introduced generic (non-AIO) thread pools,
instantiated by the core migration core.
I think we are ready to apply 1-33. Avihai, please take a look !
Sure, will try to do it by EOW.
Thanks,
When were you planning to apply?
before EOW :)
Hehe, OK will go over it today/tomorrow.
Thanks.
