Igor, this is a open that i did not pass a buffer as parameter to RFIT as tried the way you suggested, but failed. May be i am not very good at ASL, i need more time to try. So let's keep the way as it is, i will improve it later. Thanks! Changelog in v4: 1) drop fit lock and post_hotplug_cb 2) move nvdimm hotplug code to hw/acpi/nvdimm.c 3) introduce length field to indicate the fit size 4) nvdimm acpi cleanup 5) doc typo fixes Changelog in v3: 1) use a dedicated interrupt for nvdimm device hotplug 2) stop nvdimm device hot unplug 3) reserve UUID and handle for QEMU internally used QEMU 5) redesign fit buffer to avoid OSPM reading incomplete fit info 6) bug fixes and cleanups Changelog in v2: Fixed signed integer overflow pointed out by Stefan Hajnoczi This patchset enables nvdimm hotplug support, it is used as pc-dimm hotplug, for example, a new nvdimm device can be plugged as follows: object_add memory-backend-file,id=mem3,size=10G,mem-path=/home/eric/nvdimm3 device_add nvdimm,id=nvdimm3,memdev=mem3 and unplug it as follows: device_del nvdimm3 Xiao Guangrong (3): nvdimm acpi: introduce fit buffer nvdimm acpi: introduce _FIT pc: memhp: enable nvdimm device hotplug default-configs/mips-softmmu-common.mak | 1 + docs/specs/acpi_nvdimm.txt | 68 +++++++- hw/acpi/ich9.c | 8 +- hw/acpi/nvdimm.c | 289 ++++++++++++++++++++++++++++---- hw/acpi/piix4.c | 7 +- hw/i386/acpi-build.c | 9 +- hw/i386/pc.c | 16 ++ hw/mem/nvdimm.c | 4 - include/hw/acpi/acpi_dev_interface.h | 1 + include/hw/mem/nvdimm.h | 22 ++- 10 files changed, 377 insertions(+), 48 deletions(-) -- 1.8.3.1
