Hi,
yesterday, I was playing with PowerTop and my iwl3945 still is in the
TOP 3 of energy user.
Inspired by the recently published ASPM doc from Luis [2] I played a
bit with ASPM.
Currently, I am using a 2.6.35-rc3 Linux-kernel with latest
acpi-2.6/release fixes.
# dmesg | grep -i aspm

Before I will try 'pcie_aspm=force' cheat-code I wanted to ask about
the status of iwlwifi and ASPM.
Is there code available. yet? Which kernel has it - linux-next,
wireless-testing GIT, iwlwifi GIT?
Which user-space apps are required?
IIRC iw [3] from GIT has already "iw: add set/get power_save commands" [4].
Anyone tested ASPM with iwlwifi hardware? Experiences?
Beyond ASPM code, what is the actual status on power-mangement for
wifi-hardware in general?
IIRC it was turned off by default (with 2.6.33?)?
Thanks for any help in advance.
Kind Regards,

I should note I discourage the usage of pcie_aspm=force, it will try
to enable ASPM for all devices which do have the capability, and this
means when you are enabling it you are not only testing ASPM on the
device you had in mind but *all* devices capable of it.

Driver code for ASPM only exists to help tweak it if for whatever
reason it does need tweaking. An example is ath9k which disables the
PLL when it uses ASPM to save power. iwlagn or iwl3945 might have
similar stuff, but not sure. Technically drivers should not need any
code for ASPM unless its driver specific tweaks.

ASPM can be used so long as you just have a PCIE bus. If the driver
has ASPM tweaks that's a different thing.

None.

That's different. Read:

iwl3945 will disable L0s if L1 enabled, and enable L0s if L1 disabled.
Please see iwl_apm_init which is called by iwl3945_apm_init
