[Qemu-devel] [RFC PATCH 00/11] Generate ACPI v5.1 tables and expose it to guest over fw_cfg on ARM
This patch series generate seven ACPI v5.1 tables for machine virt on ARM. The set of generated tables are: - RSDP - XSDT - MADT - GTDT - FADT - FACS - DSDT These tables are created dynamically using the function of acpi-build-utils.c, taking into account the needed information passed from the virt machine model. When the generation is finalized, it use fw_cfg to expose the tables to guest. This patchset is based on Igor Mammedov's branch which can be found at below git tree: https://github.com/imammedo/qemu/commits/ASL_API_v2 And this patchset refers to Alexander Spyridakis's patches which are sent to qemu-devel mailing list before. http://lists.gnu.org/archive/html/qemu-devel/2014-10/msg03987.html As UEFI (ArmVirtualizationQemu) doesn't support downloading ACPI tables over fw_cfg, I just do compile test and start a guest with UEFI.
