Hi all, It's been a while.
This patch enables ACPI support for ARM64 which allows IPFire to boot on ARM "server" machines which use EFI/TianoCore to boot.
One such example is the QEMU arm64 "virt" machine with an EFI firmware - https://releases.linaro.org/reference-platform/enterprise/latest/uefi/
The arm64 images from "standard" distros (Debian/Ubuntu/Fedora/etc.) are designed to work with this EFI+ACPI combination.
There should be no regressions for any current arm64 hardware supported by IPFire - Linux will only use ACPI tables if present, if not fallback to device tree.
The use case for this is to run our hardware[1] using the muvirt[2] VM host, which also allows some "blending" of OpenWrt functions on the host, e.g the host can manage bridging of Ethernet ports and WiFi hostapd so IPFire can work with simple Ethernet interfaces for the Red/Green/Blue/Orange.
You can see the Fireinfo profile for the VM here - https://fireinfo.ipfire.org/profile/67aa9a9cff94f3ef8f61866197a57106ccdcea4b
I have successfully speedtested ~1Gbps though this virtualized setup so this should provide more than adequate performance for most situations.
It is not possible to run IPFire directly on our LS1088 (Ten64) platform at the moment as 4.14 does not have working Ethernet (DPAA2) and PCIe controller drivers. It is possible to backport them from later kernels (and I did have a go at this a few months ago) - but it is a very large patch (>1M lines) and that is before considering any of the features and fixes in more recent kernels (e.g backporting PHYLINK).
When IPFire moves to a newer kernel that would be a good time to revisit this.

Mathew McBride (1): kernel: enable ACPI support on ARM64
config/kernel/kernel.config.aarch64-ipfire | 99 +++++++++++++++++++++- 1 file changed, 96 insertions(+), 3 deletions(-)
ACPI (with EFI) is used on ARM systems conforming to the Server Base Boot Requirements (SBBR) and is an optional on embedded systems (EBBR).
Up to now the ARM64 boards supported by IPFire use U-Boot and device tree so ACPI was not turned on.
The immediate use case here is to run under virtualization, using my muvirt project[1] I can run IPFire on our Traverse Ten64 system. For reasons I'll explain separately it is not currently possible to run stock IPFire on this system.
This change also enables the EFI RTC driver which is presented by the qemu arm64 virt machine.

Hello Michael, Yes - this is the exact same symptom (no serial output after GRUB handoff) I see if I boot the current core148 image.
As there is no DTB being presented by the firmware (only ACPI tables), the kernel won't be able to find the serial UART to use.

Hi,
Ah that is good to hear.
I didn’t have time to investigate, and so far I have personally only worked with IPFire aarch64 in KVM virtual machines where it simply boots fine.
