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. But I contacted Laszlo Ersek before, he says that if qemu can expose the generated ACPI tables over fw_cfg, he can quickly add support in UEFI. So just send this out and make it go forward. Todo: 1) add GPIO controller in virt and expose it through ACPI 2) add cpu hotplug support Any comments are welcome.
