From: Shannon Zhao <shannon.z...@linaro.org>
This patch series generate seven ACPI tables for machine virt on ARM.
The set of generated tables are:
- RSDP
- RSDT
- MADT
- GTDT
- FADT
- DSDT
- MCFG (For PCIe host bridge)
These tables are created dynamically using the function of aml-build.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.
You can fetch this from following repo:
http://git.linaro.org/people/shannon.zhao/qemu.git ACPI_ARM_v5
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
Thanks to Laszlo's work on UEFI (ArmVirtualizationQemu) supporting downloading
ACPI tables over fw_cfg, we now can use ACPI in VM. I have done following vm
startup test and attach virtio-net-pci, e1000:
xp, windows2008, sles11 on X86
Fedora Linux kernel on ARM64
Note:
As upstream kernel doesn't support ACPI PCI host bridge on ARM64, so I use the
Fedora Linux kernel from following address:

changes since v4:
* use trace_* instead of DPRINTF (Igor & Alex)
* use standard QEMU style for structs (Michael)
* add "-no-acpi" option support for arm
* use extractNN for bits operation (Alex)
* use AmlReadAndWrite enum for rw flags (Igor)
* s/uint64_t/uint32_t/ (Igor)
* use enum for interrupt flag (Igor)
* simplify aml_device use in DSDT (Alex)
* share RSDT table generating code with x86 (Igor)
* remove unnecessary 1 in MCFG table generating code (Alex & Peter)
* use string for ToUUID macro (Igor)
* aml_or and aml_and use two args (Igor)
* add comments on UUID (Michael)
* change PCI MMIO region non-cacheable (Peter)
* fix wrong io map (Peter)
* add several reviewed-by's from Alex, thanks
changes since v3:
* rebase on upstream qemu
* fix _HID of CPU (Heyi Guo)
* Add PCIe host bridge
changes since v2:
* rebase on Igor Mammedov's new branch ASL_API_v3
* use rsdt instead of xsdt according to Igor Mammedov's suggestion
changes since v1:
* fix bug found by Laszlo
* move common helpers into dedictated file and change generating
table order according to Igor's comments
* fix copyright and function name according to Michael's comments
