From: Shannon Zhao <shannon.zhao@xxxxxxxxxx> This patch set adds ACPI support for arm64 on Xen. The design document could be found from [1]. Xen reads static tables described by ACPI standard (6.0) from uefi and configures timer, GIC and UART. ACPI tables are modified to enable PSCI, HVC and Xen specific information and mapped into Dom0 address space. A minimal device tree is created to pass EFI table which contains memory layout (which cannot be passed using ACPI) and RSDP pointer to Dom0 through the node "uefi" under /hypervisor node. Dom0 parses dynamic ACPI tables and configure other peripherals. Patch 1 reverts "xen/arm: vgic-v2: Drop cbase from arch_domain" because d->arch.vgic.cbase will be used by creating Dom0 MADT table later. Patches 2-36 add ACPI support for Xen/uefi interface. Patches 37-62 add ACPI support for Xen/Dom0 interface. Last patch "xen: arm64: Add ACPI support" enables the support for ACPI so that individual patches do not affect working xen code base. ACPI is now configurable via command line option "acpi=". To boot from ACPI this parameter should be set to "force". Patches are tested on FVP base model. Instructions for reproducing the setup and working code base can be found from the following repositories wiki[2], Xen[3], Linux[4], UEFI[5]. Also you can get the test scripts and firmware binaries from[6]. Note currently the EFI runtime service is not added in this patch set since I didn't figure out a good way to support that. Dom0 will check if Xen supports runtime service. If not, Dom0 will not initialize runtime services. It's a long time since previous patch set and most work has been done. So I send this patch set out without runtime service support and later I could continue working on adding runtime service support or maybe other people who know this better could help work on that based on this patch set.
