Re: [Announce] kernel-plus for Harmattan
 
btw, are you looked for latest bluez and modules backport?

Not sure how the bluetooth is configured in this kernel. But, here are some info on what we may want applied

Code:
[*] Networking support --->
  <*> or <M> Bluetooth subsystem support --->
    <*> or <M> RFCOMM protocol support
    [*] RFCOMM TTY support
    <*> or <M> BNEP protocol support
    [*] Multicast filter support
    [*] Protocol filter support
    <*> or <M> HIDP protocol support

    Bluetooth device drivers --->
      add here what we need
BLuez 4.97 . Yeah, I have compiled it - lets go test

Add me to the Harmattan team and I'll start committing to the repo on there!

Also, change the default branch to harmattan-2632 ;)

I believe this could possibly enable the option for USB serial console.
I believe that this is the driver for a USB to serial stick, in which case won't work until the Hostmode-on-N9 thing gets done.

An alternative is this totally 1337 method of getting to the kernel buffer.
Perhaps support for copying the buffer could be added in the next ubiboot - it's at a fixed location, it just needs to be copied into a file.

Haven't checked yet. I was planning to update BlueZ all the way to the latest version to allow BT4.0LE, but I don't know if we still want the Nokia patches.

It is doable, yes. The problem however is that after a kernel panic you need a hard reset to get to boot again, and this may corrupt the memory of the device. I am not sure how the poweroff on N9 works, though, it may even retain voltages to the memory chip?
If the voltage is cut it depends on the memory device on how long the old state is held in the device.

I remember doing some experiments with Commodore 64 when that device was state of the art; I had a picture in memory, and when I power-cycled it and redrew the memorymap after the device came back to life it was pretty much still there.
To completely get rid of the drawing, so that it was not recognizable any longer took a power cut of maybe 30 seconds!

On those days memory cells were however at least 3 orders of magnitude larger, which may affect your mileage :D

Can add opptimizer module startup at booting?

Please dont :D

install attachment to load opptimizer module on demand by opptimizer ui. just cutted modules from package and patched loader to work with kernel-compiled modules

Oh, those were the days......
Thats how I 'hacked' a copy of all my protected games ;)

Getting myself a second N9 :) 64G, black, all-inclusive :) 100€, good price ?
