Sure, I agree with that, but it also will enable ASPM for *all*
devices which have the capability which IMHO is a terrible idea for
users when all they want to do is enable ASPM for one device. Instead
I recommend users to enable ASPM for their devices selectively and
from userspace.

First mac80211 runs out of memory ... it cannot even allocate enough

Next driver runs out of memory.
Note that the above are all atomic allocations that fail and should be
able to recover.
Is your system low on memory? Are you running applications that take a
lot of memory? Does your wifi connection drop or otherwise suffer at the
time you see these messages?

It buys you enabling of ASPM on devices that the BIOS hasn't configured,
which is legitimate and useful.

That is known. I posted it once or twice. It is b43 making bad
assumptions about mac80211 behavior. And mac80211 behavior changed...
b43 does modify the number of queues in the data structure after it
registered things to mac80211. That used to work properly in the past.
But it breaks now. The init does have to be re-ordered and implementation
of async firmware loading is required to fix that.

It only works by accident anyway. But I already said that several times.

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.
> I wanted to ask about

> Is there code available. yet?
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:

* Recent results with BCM4312 on Netbook
From: Larry Finger @ 2010-06-22 15:36 UTC (permalink / raw)
To: Michael Buesch; +Cc: b43-dev, wireless, John Linville
Michael,
I have some good news. The Netbook that came from John is suddenly
developing DMA errors for the BCM4312, even though it does not have a
Phoenix BIOS. I have no idea why it did not fail this way earlier, but at
least I have a machine to debug that failure.
My first discovery is that if PIO mode is to be used, it is not sufficient
to load the module with the "pio=1" option, but that both "qos=0" and
"nohwcrypt=1" options must also be used, at least for WPA/WPA2 networks.
No other combination works. In addition, the automatic failover to PIO
mode does not work unless those two options were used when the module was
loaded. Thus both of the following work:
modprobe b43 pio=1 qos=0 nohwcrypt=1
modprobe b43 qos=0 hwcrypt=1
The second example gets a fatal DMA error and resets the controller before
the network comes up. I tried setting the latter two options before the
controller reset call in the failover, but that did not work.
If you have suggestions on changes in the switch from DMA to PIO mode,
please send them to me. In the meantime, I will be looking at differences
in the MMIO traces between wl and b43 to try to fix the DMA problem at the
source of the trouble.

* [PATCH 2/2] at76c50x-usb: Extract bssid from authentication frame
From: Sebastian Smolorz @ 2010-06-22 14:55 UTC (permalink / raw)
To: kalle.valo; +Cc: linux-wireless
In-Reply-To: <201006221651.24853.Sebastian.Smolorz@gmx.de>
The driver at76c50x-usb is unable to authenticate with an AP since
kernel 2.6.31 for the following reason: The join command of the firmware
needs to be sent with the right bssid before any transmission can start.
Before kernel 2.6.31 mac80211 informed its drivers about the changing
bssid early enough for at76c50x-usb but during the development of 2.6.31
mac80211's behaviour changed. Now a new bssid is set after the
association.
This patch changes the tx routine of the driver at76c50x-usb in such a
way that a new bssid is extracted from an authentication frame and the
join command with that bssid is processed.

This patch does a simple code move of at76_join() so that
at76_mac80211_tx() follows at76_join() in the driver's source file.
This is a preparatory patch for the following patch where we need
to call at76_join() from at76_mac80211_tx() in order to
authenticate successfully with a bssid.

Hello ath5k-list and linux-wireless-list!
I am sorry, if this is a double-post. I sent this message to the wrong
address before. I apologize.
For testing reasons I would like to disable backoff times in ath5k.
In the code of ath5k we have the macro AR5K_TXQ_FLAG_BACKOFF_DISABLE in
file linux-2.6.34/drivers/net/wireless/ath/ath5k/ath5k.h. It is issued
in the file linux-2.6.34/drivers/net/wireless/ath/ath5k/qcu.c in line 384.
How can this option be activated?

* ASPM status for iwlwifi and power-management (in general)

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,

* rt2500usb: WPA2 TKIP+AES does not work with HW encryption
From: Ondrej Zary @ 2010-06-22 10:38 UTC (permalink / raw)
To: Ivo Van Doorn; +Cc: rt2x00 Users List, linux-wireless
Hello,
I'm (again) trying to solve (debug) a weird problem with Asus WL-167G:
0b05:1706 ASUSTek Computer, Inc. WL-167G v1 802.11g Adapter [Ralink RT2500USB]
The problem only appears when HW encryption is enabled and connecting to an AP
configured as WPA2 TKIP+AES.
HW encryption works when the AP is configured as TKIP-only or AES-only. It
also works when AP is configured as TKIP+AES but wpa_supplicant is forced to
use TKIP as pairwise cipher (pairwise=TKIP)
SW encryption works always.
The problem is that no packets are transmitted. I can't see DHCP broadcasts on
other machine using tcpdump. But when I run tcpdump on the rt2500usb, I see
broadcasts from the other machine, so receive seems to work fine.
Added some printk()s to the driver, 6 packets from unsuccessful DHCP:

Seems that it's trying to use CCMP, which is good. I wonder if the keys are
properly handled in rt2500usb_config_key. They seem to be uploaded to the HW
correctly (one at index 0, one at 1) - but can't tell without any HW docs.
I did some framedumps before but don't know what to do with them (what to
look for):

With ath9k hw itself does not blink LED based on the traffic, it is
the driver which turns on/off LED based on tx/rx.

Yeah, before Vivek's patch the driver was hard-coding the LED
behaviour. After this patch, the behaviour would be based on
a modparam.

The existing LED implementation looks simple. As the blink rate is
determined in driver dynamically, I'm not quite sure integrating LED
trigger, would review this in detail later.

You cannot.
"dB" is without a reference. Is only a relative measurement. You can, however,
convert "dB" into some factor.
What we were talking about was "dBm". Here we use a reference point of one
milliwatt. Now you can convert dBm to milliwatt.
Another example of a "made absolute by using a reference" logarithmic scale is
the gain of antennas. It's usually described in dBi or dBd. The first takes
the (hypothetical) isotropical antenna, the second an dipol as reference.
For more info, search for "dBm" in http://en.wikipedia.org/wiki/Decibel

I'm not sure. I was mostly describing the use in iwlwifi, and since I
don't know how ath9k works I can't really comment much. It just seemed
to me that the driver was also hard-coding the behaviour of the LEDs,
which the user in that thread didn't like for iwlwifi, so integrating
with the LED trigger stuff could be worthwhile for ath9k? Or maybe it
does and I'm reading the patches incorrectly.

Sorry for a late reply. LED implementation with ath9k is completely
manual, fully controlled by driver (We have to set/clear a particular
gpio pin to turn on/off the LED every time). on/off period during blink
is based on the number of brightness_set() on tx/rx led trigger. Do
you think your suggested implementation would help in this case too?
thanks,

* [PATCH] ath9k: Add a module parameter to disable led blinking.
From: Vivek Natarajan @ 2010-06-22 6:22 UTC (permalink / raw)
To: linville; +Cc: linux-wireless
Some vendors require the LED to be ON always irrespective of any
radio activity. Introducing a module parameter to disable blinking,
so that one can choose between always on or led blink during
activity.

I agree with John. Let's not change the existing default pattern
(blinking during activity) and use this option to disable blinking
if someone wants it.

hi jara!
thanks, i was able to reproduce the problem here. can you try this patch, it
should fix it. it's just one line, so you could also change that 1 to a 4 in

ath5k: fix antenna div gc for <= AR5K_SREV_PHY_2413
Commit 39d5b2c83ca8904b6826a0713263a4e5a9c0730a "ath5k: update
AR5K_PHY_RESTART_DIV_GC values to match masks" introduced a regression on
PHY
chips older than AR5K_SREV_PHY_5413, which caused signal values to be
about
10dB less that before. This patch reverts the AR5K_PHY_RESTART_DIV_GC
values to
the same values which were effectively used before (without the bitmask
mistake). This brings signal levels back to normal on these PHY chips.

Luis,
The patch that I sent John is already Cc stable@kernel.org, though it
may not now apply after 56bf882230d2266a2e07b7f404dc96d157a65daa 'Revert
"wireless: hostap, fix oops due to early probing interrupt"'. I'll check
in the morning and craft a backported patch if necessary.

Because due to card advertisement, CONFIG_PCIEASPM already disables L0s
and L1 on the card, therefore my patch does nothing.

Come to think of it, would this be welcomed upstream in the PCI utils
