From: Reinette Chatre <reinette.chatre@intel.com>
Commit "iwlwifi: make debug level more user friendly" cleaned up the
debug level handling. In doing so it created a single global debug
level for all devices. Some setups do consits of more that one iwlwifi
device and in these setups there is a requirement that debug levels
should be unique per device.
We now re-introduce the per device debugging while maintaining the
cleanup effort of the previous patch.
The maintain the global debug level and now introduce a per-device debug
level that will be used if it (the per-device debug level) is set. The
per-device debug level can be controlled via the debug_level sysfs file
while the global debug level is controlled by the debug module parameter.

From: Reinette Chatre @ 2009-08-07 22:41 UTC (permalink / raw)
To: linville; +Cc: linux-wireless, ipw3945-devel, Wey-Yi Guy, Reinette Chatre
From: Wey-Yi Guy <wey-yi.w.guy@intel.com>
The traffic buffer will only beallocated and used if either bit 23
(IWL_DX_TX) or bit 24 (IWL_DL_RX) of "debug" is set;
example: "debug=0x800000" - log tx data traffic
"debug=0x1000000" - log rx data traffic
"debug=0x1800000" - log both tx and rx traffic
The traffic log will store the beginning portion (64 bytes) of the
latest 256 of tx and rx packets in the round-robbin buffer for
debugging,
user can examine the log through debugfs file.
How to display the current logged tx/rx traffic and txfifo and rxfifo
read/write point:
"cat traffic_log" in /sys/kernel/debug/ieee80211/phy0/iwlagn/debug
directory
By echo "0" to traffic_log file will empty the traffic log buffer and
reset both tx and rx taffic log index to 0.

From: Reinette Chatre @ 2009-08-07 22:41 UTC (permalink / raw)
To: linville; +Cc: linux-wireless, ipw3945-devel, Wey-Yi Guy, Reinette Chatre
From: Wey-Yi Guy <wey-yi.w.guy@intel.com>
Break down the traffic type and counter for both Tx and Rx.
Enhance the tx_statistics and rx_statistics debugfs function and move
to /sys/kernel/debug/ieee80211/phy0/iwlagn/debug directory to help
better debugging both driver and uCode related problems.

From: Wey-Yi Guy <wey-yi.w.guy@intel.com>
Adding debugfs function to show current TxFifo/RxFifo read/write
pointer, plus the current tx queue status (wake/stop) for both real and
virtual queue.
This is part of debug feature set to help debugging driver/uCode.
use tx_queue and rx_queue in
/sys/kernel/debug/ieee80211/phy0/iwlagn/debug directory to show the
current read/write pointer for both TxFifo and RxFifo queue

Display statistics notification information
The information break down into
uCode_tx_stats
uCode_rx_stats
uCode_general_stats
and can be found in /sys/kernel/debug/ieee80211/phy0/iwlagn/debug
directory
The statistic information display in debugFs is based on the last
statistics notification from uCode; it might not reflect the current
uCode activity. Using "watch" command to monitor the uCode
activity should give up-to-date statistics provided by uCode.

To: linville; +Cc: linux-wireless, ipw3945-devel, Wey-Yi Guy, Reinette Chatre
From: Wey-Yi Guy <wey-yi.w.guy@intel.com>
Display sensitivity and chain noise data to help understand the current
environment and RF condition.
The data is feeded by statistics notification and Beacon from uCode;
then used by sensitivity calibration and chain noise calibration to
determine how DSP should react to the environment changes

commit "iwlwifi: uCode Alive notification with timeout" introduced a more
reliable mechanism for ucode loading. Unfortunately we hit a problem with
it frequently enough to make a 4965 unusable. The problem can be seen in
debug log below. What this code attempts is to set runtime ucode up to
load, start a timer to wait for the alive response from runtime ucode, and
if it times out it tries again. As can be seen below we receive the alive
response and wake the waiting task _before_ the tasks starts waiting. The
task thus times out as the alive response is not received while it is
waiting for it and it restarts the device. This starts the cycle all over
again.

For legacy thermal throttling, set the new Thermal Throttling
state and change power index when thermal throttling manager detects
temperature changed. The current implementation sets the state to the
previous Thermal Throttling state, which causes system to enter wrong
power index. The worse case, it will trying to set the
lower power index when device reach critical temperature, it will cuase
issue for both system and the device.

Some of the thermal throttle data structures and code
are really very intermingled with the sleep (power)
control code. They really do belong together in a way
since the thermal throttle code uses powersaving to
achieve its goal, but it's making it hard to work on
the powersave code. Split this up to make that easier.
I've also changed the antenna defines to an enum and
used the same enum for RX and TX.

When compiling without CONFIG_IWLWIFI_DEBUGFS there is a missing
iwl_update_stats symbol. This is fixed by making this function an inline in
the case when CONFIG_IWLWIFI_DEBUGFS is not set due to the hot path in
which it is used.

To: linville; +Cc: linux-wireless, ipw3945-devel, Johannes Berg, Reinette Chatre
From: Johannes Berg <johannes@sipsolutions.net>
Depending on required latency requested by pm_qos (via mac80211)
we can automatically adjust the sleep state. Also, mac80211 has
a user-visible dynamic sleep feature where we are supposed to
stay awake after sending/receiving frames to better receive
response frames to our packets, this can be integrated into the
sleep command.
Currently, and this patch doesn't change that yet, we default
to using sleep level 1 if PS is enabled. With a module parameter
to iwlcore, automatic adjustment to changing network latency
requirements can be enabled -- this isn't yet the default due
to requiring more testing.
The goal is to enable automatic adjustment and then go into the
deepest possible sleep state possible depending on the networking
latency requirements.
This patch does, however, enable IEEE80211_HW_SUPPORTS_DYNAMIC_PS
to avoid the double-timer (one in software and one in the device)
when transmitting -- the exact timeout may be ignored but that is
not of big concern.
Note also that we keep the hard-coded power indices around for
thermal throttling -- the specification of that calls for using
the specified power levels. Those can also be selected in debugfs
to allow easier testing of such parameters.

The enabling of powersaving had a big impact on reliability and
performance. Throughput on n band suffered especially. With power save
support enabled we see significant ping response times, dropped frames, and
reduced throughput. These are captured in the following bug reports:
http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2051
http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2053
Disable power save by default, add "iwl_support_ps" module parameter
that can be used to enable it again.

You are again creating driver specific parameters. But we should be
moving away from this and instead use just generic interfaces. Please,
think three times (or even more) whenever creating new driver specific
interfaces, be it module parameters, sysfs files etc.. It's a
maintenance nightmare and also very confusing for the users. We need to
focus on nl80211 and make it work properly with all drivers.
For the problem at hand, I see two options:
1. Users seeing the problem disable power save either via wext or with
CONFIG_CFG80211_DEFAULT_PS and everyone else still can use power
save. The issue will be investigated and fixed. If the AP is buggy,
there isn't much we can do.
2. If you think the problem is widespread, remove
IEEE80211_HW_SUPPORTS_PS from the driver, fix the issues and renable
power save support.

What we have done here is not intended to be maintained at all - this is
why the module parameter description reads "power save support
(deprecated) (default disabled)" - it is deprecated from the beginning.

Please take a look at those bug reports. What we are seeing is huge ping
delays ( > 1000ms rtt), dropped frames which is stalling connections,
and throughput dropping in half. This is too severe to have powersave
enabled at this time.

Yes - this is the goal of this patch. At the same time we would also
like to make it easier for the people who are testing this issue right
now and having the module parameter makes their life easier.
This module parameter is a temporary measure used to help us fix the
power save issues. When the issues have been resolved we will enable
power save support by default and remove the module parameter.

Yes, I understand this. But creating a new module parameters should be
added carefully only when really needed, just to avoid confusion within
users. And it sounds wrong to create a new variable which is deprecated
from the beginning. If it needs to be deprecated, don't create it at
all. Simple as that.
What I'm worried is the complexity of the driver interfaces and
configuration methods. For iwlwifi power save, after this patch, we have
now:
o Wireless Extensions
o sysfs
o CONFIG_CFG80211_DEFAULT_PS Kconfig parameter
o module parameter
Just think how confused an average Linux user will be? Instead of adding
more, we should instead decrease the ways to configure power save. sysfs
and the module parameter are high on my list for removal.

Yes, that makes sense. Then disable power save from iwlwifi until the
problem is solved (or analysed that it's a problem on AP), but don't
create a new module parameter.

The very few users who want to test this can apply a patch or edit the
source code. It's a oneliner anyway.

I'm not going to fight about this, for now, but in the future I hope
that people would consider carefully before adding hacks like this. If
all drivers create their own configuration parameters all the time, in
the end it will become a maintenance nightmare.

We could not see how any of the current measures can be used to
accomplish out goal. Fortunately Johannes implemented something that now
can be used to accomplish this.
John, could you please revert this patch? Johannes's new "cfg80211:
allow driver to override PS default" makes it possible for us to have
power save support disabled.
Thank you very much

Yes, Johannes' idea is a perfect compromise. Thank you both.
