Acpi

了解Thinkpad T430s BIOS的ACPI喚醒程式碼/DSDT(Differentiated System Description Table)

  • June 18, 2017

我想修剪筆記型電腦的喚醒事件。有人可以向我解釋這 4 個字母程式碼 - 它們實際上代表哪些設備?

$ cat /proc/acpi/wakeup
Device  S-state   Status   Sysfs node
LID   S4    *enabled   platform:PNP0C0D:00
SLPB      S3    *enabled   platform:PNP0C0E:00
IGBE      S4    *enabled   pci:0000:00:19.0
EXP3      S4    *disabled  pci:0000:00:1c.2
XHCI      S3    *enabled   pci:0000:00:14.0
EHC1      S3    *enabled   pci:0000:00:1d.0
EHC2      S3    *enabled   pci:0000:00:1a.0
HDEF      S4    *disabled  pci:0000:00:1b.0

我在下面記錄了一些發現作為答案。似乎現在圖片中只缺少 IGBE 和 HDEF。

這是部分答案。從ACPI 喚醒 4 個字母的程式碼是什麼意思?我理解以下內容:

LID  - laptop lid
EXP3 - PCI Express Root Port nr 3 - could be broadband modem in my case (not sure how to pinpoint if it is actually in slot 3)
XHCI, EHC1, EHC2 - USB controllers

現在猜測:

SLPB - sleep button :-)

最後,什麼是 IGBE 和 HDEF?
