I got it little bit further, tested simple.c from: http://talk.maemo.org/showthread.php?t=37356
I think I need better minimal test-case.

Code:

wget http://repo.merproject.org/obs/nemo:/devel:/hw:/ti:/omap3:/n9xx-common/latest_armv7hl/armv7hl/ti-omap3-sgx-1.4.268.5-12.1.Nemo.Adaptation.N9xx.armv7hl.rpm

Got it compiled.

This thread is about Linux n900 3.12.0-rc5+ #2 PREEMPT Tue May 27 15:19:59 BRT 2014 armv7l GNU/Linux, but I think newer is better

(I have read what is not working with it)

I believe that you can install

Code:

qemu-system-arm/qemu-user-static

, copy the static binary into the arm filesystem's /usr/bin/, and then chroot into it on a x86 system. Performance will not be great, and it has been a year since I last used this setup, but it shoul work :-)

As you are bringing this up, I have a couple of questions:
* I would like to build this kernel and give it a try, but could not clone the repo. Do I need to register to clone it?
* in the jessie setup with the 3.12 kernel, I have horrible battery life. Is there a kernel config or patchset that may improve this matter?

Regarding the SGX drivers, it would be great if we could build weston on the N900, and maybe try maynard. With the right drivers this should yield good performance. However, I must say that I lack knowledge in this respect. So here goes the question: with the driver setup we have at hand, is it feasible to get weston to run?

In http://www.collabora.com/projects/graphics/ there is even mention of it running on powervr.

Someone has built Nemo with basic Wayland support for the N900. Perhaps this would be somewhere to look?

You don't need to register. Pali's tagged 3.16-rc1 just a few hours ago. To clone it run the following:

Code:

$ git clone git://gitorious.org/linux-n900/linux-n900.git
$ git checkout v3.16-rc1-n900

I didn't try what Pali pushed yesterday so dunno if it even boots. He was very busy lately, so we somehow "split" and I was working on my own trees.

Anyway, I will push 3.16-rc1 that boots with DT and has SGX and cmt-speech drivers as soon as I find some free time to clean up my tree.

Thanks for the hint. I will give it a try. The image was build with 3.12 and there are plenty new stuff since I last checked.

The one I could not clone was this one: https://gitorious.org/linux-n900/fre...ons-linux-n900

try this one git://gitorious.org/linux-n900/freemangordons-linux-n900.git branch v3.16-rc1-n900

to build it follow the instructions on http://elinux.org/N900#DT_Kernel_Compilation

I tested it with qemu, it boots, should boot on the device as well.

EDIT:
for building, you need to use rx51_defconfig, it has all the needed stuff enabled

@fmg It does boot :-)

Code:

Linux n900 3.16.0-rc1+ #2 PREEMPT Wed Jun 18 13:29:27 BRT 2014 armv7l

I had to disable CONFIG_SYSFS_DEPRECATED, otherwise kernel loads but boot fails.

For those willing to live on the bleeding edge here follows uImage/uInitrd and modules suitable to be used on the jessie image: https://187.115.25.181/public/n900/3.16-rc1.tgz

What about SGX driver, are you able to load it and start X ? I guess you'll need userspace from Meego
