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_v7
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.
Now upstream kernel applies ACPI patchset, so we can boot it with ACPI,
while we need to apply patches[1] to make tty work, patch[2] to make
virtio-mmio work and apply patch[3] and the relevant patches to make PCI
devices works, e.g. virtio-net-pci, e1000.
On the other hand, you can directly use the Fedora Linux kernel from
following address:
https://git.fedorahosted.org/cgit/kernel-arm64.git/log/?h=devel
I've done test with following VM:
xp, windows2008, sles11 on X86
upstream kernel and Fedora Linux kernel on ARM64
In addtion, dump all the acpi tables, use iasl -d *.dat to convert to
*.asl and use iasl -tc *.asl to compile them to *.hex. No error appears.
If you want to test, you could get kernel Image from [4] which contains
uart, virtio-mmio, pci ACPI drivers, UEFI binary from [5] and Qemu
command line example from [6].
