Re: [ath5k-devel] [PATCH v2] ath5k: disable ASPM

Quoting "Maxim Levitsky" <maximlevitsky@xxxxxxxxx>:

Card (at least mine) advertises its as a 'pre pci 1.1 device'.
Therefore if I enable CONFIG_PCIEASPM, the pci core will automaticly
disable ASPM (both L0s and L1) on this card.
I won't be surprised that windows does the same.


Even if CONFIG_PCIEASPM compiled in, ASPM code can be disabled by user with pcie_aspm=off option, leaving BIOS-enabled L0s on.
