hw: move char backends to backends/ Braille and msmouse support is in hw/, but it is not hardware. Move it to the backends/ directory. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> 2013-02-04 03:21:00 +08:00
QOM-ify the TPM support QOM-ified the TPM support with much code borrowed from the rng implementation. All other TPM related code moves will be provided in a subsequent patch.

add memdev backend infrastructure Provides framework for splitting host RAM allocation/ policies into a separate backend that could be used by devices. Initially only legacy RAM backend is provided, which uses memory_region_init_ram() allocator and compatible with every CLI option that affects memory_region_init_ram().

Add memfd based hostmem Add a new memory backend, similar to hostmem-file, except that it doesn't need to create files. It also enforces memory sealing. This backend is mainly useful for sharing the memory with other processes. Note that Linux supports transparent huge-pages of shmem/memfd memory since 4.8. It is relatively easier to set up THP than a dedicate hugepage mount point by using "madvise" in /sys/kernel/mm/transparent_hugepage/shmem_enabled. Since 4.14, memfd allows to set hugetlb requirement explicitly. Pending for merge in 4.16 is memfd sealing support for hugetlb backed memory.
