v1: https://lore.kernel.org/r/20240904191635.3045606-1-pet...@redhat.com 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 is the fix to the problem, while the rest three patches are cleanups. Thanks, Peter Xu (4): KVM: Dynamic sized kvm memslots array KVM: Define KVM_MEMSLOTS_NUM_MAX_DEFAULT KVM: Rename KVMMemoryListener.nr_used_slots to nr_slots_used KVM: Rename KVMState->nr_slots to nr_slots_max include/sysemu/kvm_int.h | 7 +-- accel/kvm/kvm-all.c | 111 +++++++++++++++++++++++++++++++-------- accel/kvm/trace-events | 1 + 3 files changed, 93 insertions(+), 26 deletions(-) -- 2.45.0
