Optimization team update (11/23 ~ 11/29)

[John Lee]

Dear Community,

As Sushama (our new testing team member) indicated in
http://lists.openmoko.org/pipermail/devel/2008-November/003493.html ,
we won't have a release in Nov.  Currently the testing team is going
to do a full test on the latest testing image.  It has all the goodies
we did and a lot of improvements over Om2008.9, so please try it and
report any error you find.


Upgrade howto:

>From Om2008.9 it's recommanded to upgrade with the following steps:

sed -i -e 's%Om2008.8%testing%' /etc/opkg/*.conf
/etc/init.d/xserver-nodm stop
screen -DR
opkg update
opkg -force-overwrite upgrade
# (please ans Y to all questions)
# (the sshd (dropbear) will restart, so you need to reconnect and do
# 'screen -DR' again)
opkg upgrade
shutdown -r now

To get the fastest boot time you also need to remove the following
packages:

opkg remove task-base-nfs task-base-smbfs task-base-bluetooth \
task-base-usbgadget avahi-daemon avahi-autoipd blueprobe \
usb-gadget-mode portmap exquisite exquisite-theme-freerunner \
exquisite-themes


Known issues:

* GTK redraw problem
* some obsolete kernel modules still left in system
* must remove 'ro' in kernel boot parameter if you use sd boot.
* will purge your incompatible e config, so you might need to set
  stuffs like suspend time again.


Echo:

Since there are different hw versions out there (a5, a6, a7), it's
impossible to provide one alsa state file that suits all models.
However, it seems you can always find appropriate values for your
neo.  My way is to adjust
control.4 Speaker Playback Volume in
/usr/share/openmoko/scenarios/gsmhandset.state

the max value is 127, 95 works best on my a5.  With volume level 3 or
4 in qtopia dialer, the other side can hear no echo while I get good
audio quality.


Team update:

Tick helped to put his touchscreen improvement into stable-tracking,
he will work on opkg internals next.  Olv moved to look into kernel
and fso.  Erin will try bluetooth.  Julian is working on the GTK
redraw issue, please help him out.  Jeremy will fix some qtopia bugs
and keep working on suspend/resume issues.


Regards,
John
