Arm Server Base System Architecture Reference board (``sbsa-ref``)
|
|
==================================================================
|
|
|
|
The ``sbsa-ref`` board intends to look like real hardware (while the ``virt``
|
|
board is a generic board platform that doesn't match any real hardware).
|
|
|
|
The hardware part is defined by two specifications:
|
|
|
|
- `Base System Architecture <https://developer.arm.com/documentation/den0094/>`__ (BSA)
|
|
- `Server Base System Architecture <https://developer.arm.com/documentation/den0029/>`__ (SBSA)
|
|
|
|
The `Arm Base Boot Requirements <https://developer.arm.com/documentation/den0044/>`__ (BBR)
|
|
specification defines how the firmware reports that to any operating system.
|
|
|
|
It is intended to be a machine for developing firmware and testing
|
|
standards compliance with operating systems.
|
|
|
|
Supported devices
|
|
"""""""""""""""""
|
|
|
|
The ``sbsa-ref`` board supports:
|
|
|
|
- A configurable number of AArch64 CPUs
|
|
- GIC version 3
|
|
- System bus AHCI controller
|
|
- System bus XHCI controller
|
|
- CDROM and hard disc on AHCI bus
|
|
- E1000E ethernet card on PCIe bus
|
|
- Bochs display adapter on PCIe bus
|
|
- A generic SBSA watchdog device
|
|
|
|
|
|
Board to firmware interface
|
|
"""""""""""""""""""""""""""
|
|
|
|
``sbsa-ref`` is a static system that reports a very minimal devicetree to the
|
|
firmware for non-discoverable information about system components. This
|
|
includes both internal hardware and parts affected by the qemu command line
|
|
(i.e. CPUs and memory). As a result it must have a firmware specifically built
|
|
to expect a certain hardware layout (as you would in a real machine).
|
|
|
|
Note
|
|
''''
|
|
|
|
QEMU provides the guest EL3 firmware with minimal information about hardware
|
|
platform using minimalistic devicetree. This is not a Linux devicetree. It is
|
|
not even a firmware devicetree.
|
|
|
|
It is information passed from QEMU to describe the information a hardware
|
|
platform would have other mechanisms to discover at runtime, that are affected
|
|
by the QEMU command line.
|
|
|
|
Ultimately this devicetree may be replaced by IPC calls to an emulated SCP.
|
|
|
|
DeviceTree information
|
|
''''''''''''''''''''''
|
|
|
|
The devicetree reports:
|
|
|
|
- CPUs
|
|
- memory
|
|
- platform version
|
|
- GIC addresses
|
|
- NUMA node id for CPUs and memory
|
|
|
|
Platform version
|
|
''''''''''''''''
|
|
|
|
The platform version is only for informing platform firmware about
|
|
what kind of ``sbsa-ref`` board it is running on. It is neither
|
|
a QEMU versioned machine type nor a reflection of the level of the
|
|
SBSA/SystemReady SR support provided.
|
|
|
|
The ``machine-version-major`` value is updated when changes breaking
|
|
fw compatibility are introduced. The ``machine-version-minor`` value
|
|
is updated when features are added that don't break fw compatibility.
|
|
|
|
Platform version changes:
|
|
|
|
0.0
|
|
Devicetree holds information about CPUs, memory and platform version.
|
|
|
|
0.1
|
|
GIC information is present in devicetree.
|
|
|
|
0.2
|
|
GIC ITS information is present in devicetree.
|
|
|
|
0.3
|
|
The USB controller is an XHCI device, not EHCI.
