Hi All,
Is there a Linaro kernel available for the Efika MX?
Thanks!
Tom

There's at least no support for it in mainline linux.

There is some basic i.MX51 support in the mainline kernel; Amit K. of Linaro worked on this port, and ISTR him telling me it would boot to a serial console. This port was developed on the Babbage.
Whether or not the upstream bits work on the particular configuration of the Efika board is a different question, but it shouldn't be a lot of work to get it to boot at least.

I know, we are maintaining i.MX in the mainline and several people at Pengutronix are working on better MX51 support recently.

If you mean "booting with serial console up to a prompt", without any graphics or other of the fancy features, then yes, that's easy. We have that running on the Babage board, on the TX51 and on customer hardware.
However, bringing MX51 to a state like what we have today for example for MX35 or MX27 will still be a lot of work.

Tom,
What features do you need?
I plan to get atleast a working serial console on it when I get the board later this week.
However, if you need the graphics stack that your best bet is the Freescale BSP.
Cheers, Amit

network, serial cons and USB storage functional should be plenty.

Mine currently has lucid on it but it seems to be less than stable.

I'm not that adventurous ... least not yet :-)

Thanks Amit!

network,
Works in the mainline.
serial cons
Works as well.

That works as well.

Gaaaa :-) Indeed, the graphics stuff is not easy. We are working at least on minimum framebuffer support for the first cut. So don't give up so fast.
If anyone knows how the state regarding accelerated graphics is, let me know. It would be pretty interesting to support that in mainline as well. Until now, we don't have any idea if there is some documentation for the z430 core available, and if not, if that's by accident (because nobody knows) or on purpose (because it is top secret).
Some good news: the SDMA engine on the MX51 seems to work as well. We have reworked the code recently completely and patches from Sascha are on ALKML. Although they have been developed on MX35, it also seems to work on MX51. It's not feature complete, but anyway...

I'm sure someone at Freescale knows; I'll write to the Linaro TSC contacts and find out who can give us input here. There are not a lot of SoCs that ship with AMD mobile on them, so talking to FSCL is probably our best bet.
I'm sure somebody on the Linaro team has had access to graphics drivers in the mx51 BSP at some point in time, though I'm not sure what terms the BSP was provided under.

I've had access to this code under NDA at Xandros. It was not supplied with documentation for the graphics core. I suspect this is because the core is Qualcomm's and supplied to FreeScale under NDA. The only two SoC's I am aware of that use that core are SnapDragon and iMX51.

For accelerated graphics on MX51 (Z430 and Z160), the kernel module driver has been open sourced recently, but for user space libraries, they are still proprietary, and NDA is needed to access source code as well as related documents.

Do you know where we can find this open sourced version of the kernel driver?
rsc
http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=i.MX515&f... download L2.6.31_10.07.11_ER_SOURCEhttp://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=i.MX515&fpsp=1&tab=Design_Tools_Tab# you can get the driver package in drivers/mxc/amd-gpu folder, I think
