Hi
Changes in v3:
- fix rdma_migration to reset clearly (thanks danp)
- redo the cherks for migration/rdma
- rebased on top of the counters series:
[PATCH 00/21] Migration: More migration atomic counters
Based-on: Message-Id: <20230508130909.65420-1-quintela@redhat.com>
Please, review.
Changes in v2:
- rebased on top of migration-20230428 pull (second try)
- several of the patches on the PULL request
- make clean that we don't use rdma code when we don't use rdma
- create migrate_rdma() to check if we are in rdma migration.
There is no hope for this code. I am trying to cleanup the rest of
rdma calls, but the code is convoluted as hell. And it lies with the
ram counters as crazy.
Please review.
In this series (v1):
- QEMUFileHooks only had a single user, RDMA migration. Just remove the
hooks and create stubs for when RDMA is not compiled in.
- This implies that we have to move all the operations from
migration/qemu-file.c to migration/rdma.c.
- I now we can still simplify rdma_control_save_page(), but I don't
have an easy setup for testing.
- Yes, the goal of the whole operations is to be able to move
ram_file_limit from qemu-file to migration.c.
Please review.
Thanks, Juan.
