[Qemu-devel] [PATCH v4] hw/arm: Add arm SBSA reference machine |
|
Date: |
Fri, 19 Oct 2018 16:55:12 +0800 |
For the Aarch64, there is one machine 'virt', it is primarily meant to
run on KVM and execute virtualization workloads, but we need an
environment as faithful as possible to physical hardware, for supporting
firmware and OS development for pysical Aarch64 machines.
This patch introduces new machine type 'sbsa-ref' with main features:
- Based on 'virt' machine type.
- CPU type cortex-a57.
- EL2 and EL3 are enabled by default.
- GIC version 3 only.
- Re-designed memory map.
- AHCI controller attached to system bus.
- EHCI controller attached to system bus.
- CDROM and hard disc on AHCI bus.
- USB mouse and key board.
- E1000E ethernet card on PCIE bus.
- VGA display adaptor on PCIE bus.
- No virtio deivces.
- No paravirtualized fw_cfg device.
- No ACPI table supplied.
- Only minimal device tree nodes.
Arm Trusted Firmware and UEFI porting to this are done accordingly.
