[Qemu-devel] [PATCH v2 0/6] Memory API mutators |
Date: |

This patchset introduces memory_region_set_enabled() and
memory_region_set_address() to avoid the requirement on memory
routers to track the internal state of the memory API (so they know
whether they need to add or remove a region). Instead, they can
simply copy the state of the region from the guest-exposed register
to the memory core, via the new mutator functions.
v2:
- fix minor bug in set_address()
- add set_alias_offset()
- two example users
Avi Kivity (6):
memory: introduce memory_region_set_enabled()
memory: introduce memory_region_set_address()
memory: introduce memory_region_set_alias_offset()
memory: optimize empty transactions due to mutators
cirrus_vga: adapt to memory mutators API
piix_pci: adapt smram mapping to use memory mutators
