In traditional telecom market, what confused us(Huawei) was our software and
hardware coupling together oftentimes. So if we change some hardware then we
MUST modify our software, which was not our customer’s expectation. In x86 world,
we have UEFI and ACPI technologies, they are suitable to solve this problem very
well, we just upgrade our hardware and don’t need to upgrade their software,
in the meantime ACPI provides many methods on power management.
In ARM64 world, we are aiming the same thing. Following the SBBR,SBSA specs
to implement our UEFI and ACPI code, we think the patch set and arm-acpi
documentation are fine , and consider it is going on the right direction, so
