ASPM default enabled on kernel 3?

rated 0 times [ 1] [ 0] / answers: 1 / hits: 1353 / 3 Years ago, tue, november 2, 2021, 12:02:34

I would like to know if "pcie_aspm=force" is already enabled on kernel 3 or if it will be only for kernel 3.3 like the Phoronix website says. I would like to know because i want to enable it on my acer 3820tg to see if the battery lasts a little more. i'm using ubuntu 11.10 64 bit.

(ps: sorry for my bad english but i'm portuguese)

Celso

With the 3.1.1 kernel pciasmp is compiled into the kernel

grep ASPM /boot/config-3.1.1

CONFIG_PCIEASPM=y

# CONFIG_PCIEASPM_DEBUG is not set

pcie_aspm=force looks like a (kernel) boot option.

To enable that option, edit /etc/default/grub

# graphical

gksu gedit /etc/default/grub



# command line

sudo -e /etc/default/grub

Add that option in to the GRUB_CMDLINE_LINUX_DEFAULT line, after quiet and splash

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=force"

Update grub

sudo update-grub
