From: Björn Töpel <bj...@rivosinc.com> The RISC-V "virt" machine is currently missing memory hotplugging support (MHP). This series adds the missing virtio-md, and PC-DIMM support.
I've include both the ACPI MHP/GED/PC-DIMM, and virtio-md in the same series. The two patches (virtio-md) are probably less controversial, and can be pulled separately from the last patch. The first patch includes MHP that works with DT. The second patch is basic device memory ACPI SRAT plumbing. The third patch includes ACPI GED, and ACPI MHP/PC-DIMM support. Changelog v1->v2: * Cap the maximum number of supported ram slots (Daniel) * Split the ACPI parts out from virtio-md patch (Daniel) * Allow for max 1G PC-DIMM alignment per ram slot (Daniel) * Add missing defined(__riscv__) for virtio-mem code * Include PC-DIMM MHP supportin the series * Misc code structure changes Cheers, Björn Björn Töpel (3): hw/riscv/virt: Add memory hotplugging and virtio-md-pci support hw/riscv/virt-acpi-build: Expose device memory in ACPI SRAT hw/riscv/virt: Add ACPI GED and PC-DIMM MHP support hw/riscv/Kconfig | 5 + hw/riscv/virt-acpi-build.c | 23 +++++ hw/riscv/virt.c | 183 ++++++++++++++++++++++++++++++++++++- hw/virtio/virtio-mem.c | 5 +- include/hw/riscv/virt.h | 6 +- 5 files changed, 218 insertions(+), 4 deletions(-) base-commit: 01782d6b294f95bcde334386f0aaac593cd28c0d -- 2.40.1
