where are? .diff ? git repo? .deb ?

Re: MeeGo hardware adaptation for N8x0

I have an N800 I could loan to someone actively working on this or use it for testing.

Re: MeeGo hardware adaptation for N8x0

Crap, after various unsuccesful attempts to build & boot a modern kernel it seems I managed to fry my N810's camera:

(No, flashing vanilla Diablo, leaving the battery out for a while etc didn't help)

No one's to blame but me of course, but be careful out there!

Re: MeeGo hardware adaptation for N8x0

Or just messing up the kernel options? What does booting a Diablo say?

Re: MeeGo hardware adaptation for N8x0

That was Diablo :-(

Re: MeeGo hardware adaptation for N8x0

As we now have some kernels to play with on recent versions for N8x0, I suggest we start the real work.

Tools of the choice: Fedora chroot or VM. There's problems with MIC2 currently that needs to be fixed before we have proper support on Debian/Ubuntu. This guide should get you started building RPM packages for MeeGo.

I have some tasks we need to get started on in order to get N8x0 properly supported. Who will take these?

1) Adapt the kernel source package from MeeGo to make a kernel build for the N8x0. There is some work regarding 2.6.33 already we can probably piggyback on for ARM support. The patches Termana and tmr has provided should provide a good basis for this.

2) Package up Xomap for MeeGo - there is no good omapfb driver for N8x0 for Xorg sadly. Alternatively, someone can put in effort to work on this.

3) Integrators - someone good with RPM packaging that developers can contact regarding questions.

4) Testers - we need 2-3 committed testers to test the output, documentation provided, etc.

Testers so far: rlinfati

Discussion topics:

* What should be our deployment target? My suggestion is to target at least a 2GB (mini/micro)SD card and boot from there.
* What should be initial (realistic) hardware usable for MeeGo 1.0 with N8x0 HW adaptation? Remember, MeeGo 1.0 is in May
* Should we even care about the 3d drivers or should we look into OpenVG for Qt for instance?
* What would be useful to have Nokia provide in a tablets-dev.nokia.com RPM repository (closed source bits), so people can generate images with the bits.

Re: MeeGo hardware adaptation for N8x0

i have a n800, i can test... :)

2GB sounds good to me.

I would like to have WiFi and/or Bluetooth and touchscreen. HW keyboard would be a bonus .

I haven't seen much activity regarding 3D driver here in TMO so I guess it's not really working? I would choose the easier route and if OpenVG for Qt is easier, I would vote for that. 3D acceleration is nice-to-have feature, not must-have.

Re: MeeGo hardware adaptation for N8x0

I am willing to adapt the n8x0 patches to the MeeGo kernel (though I'll need to have someone else test the n800 kernel), but as I mentioned in #mer, the kernel source is only available in RPM format. Can the MeeGo Project make the source for the kernel available in plain .tar.gz format? Or is anyone willing to do this independently?

Re: MeeGo hardware adaptation for N8x0

I may be missing your point entirely, but you should be able to extract the contents of the source RPM with rpm -i or rpm2cpio on any LSB-compliant distribution.
