我用 AMD Ryzen 5700G 构建了一台新计算机，令我惊讶的是，没有获取任何传感器信息。我认为也许新的 AMD 芯片还不会被 Linux 识别，但文档却另有说法。
这是sudo sensors-detect：
# sensors-detect version 3.6.0+git
# System: Gigabyte Technology Co., Ltd. B550I AORUS PRO AX [Default string]
# Kernel: 5.14.6-arch1-1 x86_64
# Processor: AMD Ryzen 7 5700G with Radeon Graphics (25/80/0)
This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.
Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no):
Silicon Integrated Systems SIS5595... No
VIA VT82C686 Integrated Sensors... No
VIA VT8231 Integrated Sensors... No
AMD K8 thermal sensors... No
AMD Family 10h thermal sensors... No
AMD Family 11h thermal sensors... No
AMD Family 12h and 14h thermal sensors... No
AMD Family 15h thermal sensors... No
AMD Family 16h thermal sensors... No
AMD Family 17h thermal sensors... No
AMD Family 15h power sensors... No
AMD Family 16h power sensors... No
Hygon Family 18h thermal sensors... No
AMD Family 19h thermal sensors... No
Intel digital thermal sensor... No
Intel AMB FB-DIMM thermal sensor... No
Intel 5500/5520/X58 thermal sensor... No
VIA C7 thermal sensor... No
VIA Nano thermal sensor... No
内核版本应该足够新，5700G 应该被检测为“AMD Family 19h”，但显然不是。
我尝试过手动加载k10temp模块，但没有效果。我也尝试过重新安装lm_sensors、更新系统并安装第 3 方实用程序“Zenpower”，但sensors看起来仍然很可怜：
iwlwifi_1-virtual-0
Adapter: Virtual device
temp1: N/A
acpitz-acpi-0
Adapter: ACPI interface
temp1: +16.8°C (crit = +20.8°C)
nvme-pci-0400
Adapter: PCI adapter
Composite: +43.9°C
难道是 Zen 3 APU 无法检测到吗？或者我还缺少其他模块或设置吗？
答案1
Linux 5.14 中的驱动程序尚不支持这些 APU，它将在 5.15 中提供，但您现在可以获取它并在 5.14 中编译（必须安全）。
