Hi,
We are trying to make the htc dream(also known as G1) android phone
usable with a standard GNU(non android) userland.
Inside the htcdream there is a wl1251_sdio chip.
We already use the wl1251_sdio driver with a special module for
initialization.
The problem is that When the wifi is on,the battery last for about an
hour.
So we definitely need power saving features like PSM(I hope I used the
right acronym,I'm looking for the system which makes the access point
buffer frames for the phone and then we request the frames,other power
saving mode are also welcome but as I understood this one is the most
important)
Grepping for psm in the driver show that there is some sort of support
for PSM.
Unfortunately the following method of activation failed:
# ./iw dev wlan0 set power_save on
command failed: Operation not supported (-95)
# iwconfig wlan0 power period 2
Error for wireless request "Set Power Management" (8B2C) :
invalid argument "2".
and I didn't find a psm sys node.
I wonder where it has been disabled,and if I can re-enable it.
I was also told that most driver have psm disabled,I don't know the
reason tough(maybe performance,as it has a serious impact on
performance)
our (bad quality)kenrel tree can be found here(we're not yet kernel
hackers):

that was the wrong fix.
The good fix(many thanks to chr_ in #linux-wireless) was to try
compat-wireless,which bringed many more power saving features according
to him.

hmmm....
now it does that:
Apr 27 18:12:43 router hostapd: wlan0: STA 00:1f:df:65:25:23 IEEE
802.11: authenticated
Apr 27 18:12:43 router hostapd: wlan0: STA 00:1f:df:65:25:23 IEEE
802.11: associated (aid 2)
Apr 27 18:12:43 router hostapd: wlan0: STA 00:1f:df:65:25:23 RADIUS:
starting accounting session 4BA21E4D-000007D9
Apr 27 18:13:11 router hostapd: wlan0: STA 00:1f:df:65:25:23 IEEE
802.11: authenticated
Apr 27 18:13:11 router hostapd: wlan0: STA 00:1f:df:65:25:23 IEEE
802.11: associated (aid 2)
Apr 27 18:13:11 router hostapd: wlan0: STA 00:1f:df:65:25:23 RADIUS:
starting accounting session 4BA21E4D-000007DA
--->start pinging
--->ping stopping
with no messages just after the ping stopping,so maybe I need some more
patches...

iwconfig wlan0 power on now works
I wonder if it really does something tough,I will test
I changed added | IEEE80211_HW_SUPPORTS_PS in:
wl->hw->flags = IEEE80211_HW_SIGNAL_DBM |
IEEE80211_HW_NOISE_DBM;

Apr 27 18:02:18 router hostapd: wlan0: STA 00:1f:df:f8:ac:7f RADIUS:
starting accounting session 4BA21E4D-000007D8
Apr 27 18:03:24 router hostapd: wlan0: STA 00:1f:df:24:0b:7f IEEE

Apr 27 18:03:25 router hostapd: wlan0: STA 00:1f:df:24:0b:7f IEEE

So I think it's not the driver...
By the way,the thanks were lost in the mail containing only a quote and
"Denis."
so thanks a lot for the patch!!!

oops I don't know why the message wasn't included,maybe I made an error.
Anyway it last much longer,but sometimes it only last for about 50 pings
and after that no more network,tough iwconfig still say that it's
associated.
I'll check my hostapd router logs and try to put a wakelock

You need a few more patches for PS to work (on top of current compat-wireless):

I'm working on mainline mergeable versions of those..

There is a status at
http://www.htc-linux.org/wiki/index.php?title=Dream#Status
Here are preview images with FSO:
http://downloads.freesmartphone.org/releases/fso2-preview-1/htcdream/
Zhone is only a test program,it's not our goal.
Our goal is targetting the SHR distribution instead
( http://trac.shr-project.org/trac )
For now In order to have a SHR image,for now you have to build one
yourself using openembedded
Select htcdream as the machine and shr as the distribution
also include that in the local.conf:
require conf/distro/include/fso-autorev.inc
require conf/distro/include/shr-autorev.inc
http://docs.openembedded.org/usermanual/usermanual.html#chapter_getting_oe
Contains some information on how to get the build system setup.

I'm interested about this. Are there any references about this? For

2 things:
*I rebased the patches against lastest compat wireless but I don't know
where to send them...
Basically or they apply or they are already in compat-wireless(verified)
here are the one which applies:

0011-wl1251-add-reset-handling.patch
0013-wl1251-prevent-scan-when-connected.patch
