Subject: [Qemu-devel] [PATCH 0/3] memory: update coalesced_range on transaction_commit
Date: Thu, 29 Nov 2018 10:09:30 +0100	[thread overview]
Message-ID: <20181129090933.30622-1-pbonzini@redhat.com> (raw)

The e1000 driver calls memory_region_add_coalescing but
kvm_coalesce_mmio_region is never called for those regions.  The bug
dates back to the introduction of the memory region API; to fix it,
the last patch deletes and re-adds coalesced MMIO ranges when building
the FlatViews.  The first two patches are preparatory changes.

Paolo Bonzini (3):
  memory: extract flat_range_coalesced_io_{del,add}
  memory: avoid unnecessary coalesced_io_del operations
  memory: update coalesced_range on transaction_commit
