*xenial内核的内核配置

  • 772

我在哪里可以查看内核的默认内核配置Xenial？我对 USB 电源管理配置特别感兴趣，包括：

  • CONFIG_SUSPEND
  • CONFIG_HIBERNATION
  • CONFIG_PM_RUNTIME
  • CONFIG_PM 和
  • CONFIG_USB_SUSPEND

uname -r给我：4.4.38-l4t-r28.2+g174510d

configuration kernel 16.04

  1. 您当前运行的 Linux 内核config在/boot/. 文件名看起来像/boot/config-*。运行以下命令以找到确切的名称。

    ls -l /boot/config-`uname -r`

    在那里您可以找到这些配置参数是否已启用。

    对于这个 16.04 内核：

    doug@DOUG-64:/boot$ lsb_release -a
Distributor ID: Ubuntu
Description:    Ubuntu 16.04.6 LTS
Release:        16.04
Codename:       xenial
doug@DOUG-64:/boot$ uname -a
Linux DOUG-64 4.4.0-176-generic #206-Ubuntu SMP Fri Feb 28 05:02:04 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

    您寻求的信息是：

    doug@DOUG-64:/boot$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 16.04.6 LTS

doug@DOUG-64:/boot$ grep CONFIG_SUSPEND config-4.4.0-176-generic
CONFIG_SUSPEND=y
CONFIG_SUSPEND_FREEZER=y
# CONFIG_SUSPEND_SKIP_SYNC is not set
doug@DOUG-64:/boot$ grep CONFIG_HIBERNATION config-4.4.0-176-generic
CONFIG_HIBERNATION=y
doug@DOUG-64:/boot$ grep CONFIG_PM_RUNTIME config-4.4.0-176-generic
doug@DOUG-64:/boot$ grep CONFIG_PM config-4.4.0-176-generic
CONFIG_PM_STD_PARTITION=""

CONFIG_PM_SLEEP_SMP=y
# CONFIG_PM_AUTOSLEEP is not set
CONFIG_PM_WAKELOCKS=y
CONFIG_PM_WAKELOCKS_LIMIT=100
CONFIG_PM_WAKELOCKS_GC=y
CONFIG_PM=y
CONFIG_PM_DEBUG=y
CONFIG_PM_ADVANCED_DEBUG=y
# CONFIG_PM_TEST_SUSPEND is not set
CONFIG_PM_SLEEP_DEBUG=y
CONFIG_PM_TRACE=y
CONFIG_PM_TRACE_RTC=y
CONFIG_PM_CLK=y
# CONFIG_PMIC_OPREGION is not set
CONFIG_PMC_ATOM=y
CONFIG_PMBUS=m
CONFIG_PMIC_ADP5520=y
CONFIG_PMIC_DA903X=y
CONFIG_PMIC_DA9052=y
CONFIG_PM_DEVFREQ=y
CONFIG_PM_DEVFREQ_EVENT=y
CONFIG_PM_NOTIFIER_ERROR_INJECT=m
doug@DOUG-64:/boot$ grep CONFIG_USB_SUSPEND config-4.4.0-176-generic
doug@DOUG-64:/boot$

    看起来您的几个内核配置参数甚至不存在该内核。实际上从来没有 CONFIG_USB_SUSPEND，但是 CONFIG_USB_AUTOSUSPEND 出现在内核 5.1 左右。从来没有 CONFIG_PM_RUNTIME。
