This series make KVM memslots to be allocated dynamically in QEMU. It fixes a migration performance regression that I observed, reducing precopy dirty sync process from ~86ms to ~3ms each time.
Patch 1,2,4 are mostly small cleanups, the major fix is in patch 3. Thanks, Peter Xu (4): KVM: Rename KVMState->nr_slots to nr_slots_max KVM: Define KVM_MEMSLOTS_NUM_MAX_DEFAULT KVM: Dynamic sized kvm memslots array KVM: Rename KVMMemoryListener.nr_used_slots to nr_slots_used include/sysemu/kvm_int.h | 7 +-- accel/kvm/kvm-all.c | 106 ++++++++++++++++++++++++++++++--------- accel/kvm/trace-events | 1 + 3 files changed, 88 insertions(+), 26 deletions(-) -- 2.45.0
