This series is an attempt to provide device memory hotplug support on ARM virt platform. This is based on Eric's recent works here[1] and carries some of the pc-dimm related patches dropped from his series. The kernel support for arm64 memory hot add was added recently by Robin and hence the guest kernel should be => 5.0-rc1. NVDIM support is not included currently as we still have an unresolved issue while hot adding NVDIMM[2]. However NVDIMM cold plug patches can be included, but not done for now, for keeping it simple. This makes use of GED device to sent hotplug ACPI events to the Guest. GED code is based on Nemu. Thanks to the efforts of Samuel and Sebastien to add the hardware-reduced support to Nemu using GED device[3]. (Please shout if I got the author/signed-off wrong for those patches or missed any names). This is sanity tested on a HiSilicon ARM64 platform and appreciate any further testing. Note: Attempted adding dimm_pxm test case to bios-tables-test for arm/virt. But noticed the issue decribed here[5]. This is under investigation now. upstream url: https://patchwork.kernel.org/cover/11150345/ Signed-off-by: Keqian Zhu <zhukeqian1@huawei.com>
