[gentoo-embedded] openmoko overlay?

[Christopher Friedt]

Is anyone else on this list contributing to the openmoko codebase? Does 
anyone else have a FIC handheld?

I just got a freerunner a couple of days ago and threw om2008.8 on it. 
The QT interface is pretty nice and I'd like to start contributing some 
code, but I'd rather use Gentoo's build system instead of the OE build 
system.

Is anyone aware of an existing overlay ?

Cheers,

Chris

Hello,

Me and Ned Ludd are working on a embedded overlay mostly for PDAs.
The overlay is located here:
http://tinderbox.dev.gentoo.org/embedded/linwizard/overlay/
The overlay includes some fixed ebuilds for cross-compiling base
dependencies. There is also a GPE tree there that should be emergeable.
More recently, we started to work on openmoko ebuilds. It's not finished
yet.

We also provide binary packages for ARMV5TE-JL here:
http://tinderbox.dev.gentoo.org/embedded/linwizard/

I don't own a freerunner, but I can't test most of it on my HTC wizard.

Re: [gentoo-embedded] openmoko overlay?

[Christopher Friedt]

Cool - I'll check it out.

The moko is an arm920t core (armv4t arch), but I believe that the 
official packages aren't even compiled with the EABI. The core itself is 
exactly the same as that of the TS-72xx boards, which I've worked with 
extensively. The packaging, pinouts, and on-chip peripherals are really 
all that are different, so creating a toolchain is a non-issue.

The /proc/cpuinfo component of the FreeRunner's kernel is slightly 
bjorked - through some odd patches they have mashed board info into the 
cpuinfo structure somehow instead of the cleaner /proc/SBC/info structure.

I should have no problem taking my current instructions from the 
gentoo-wiki and editing them to provide info for the openmoko. U-Boot, 
and the usb-loader utility (dfu-util) are the only components that I 
have little experience with. Although it was reasonably easy enough to 
load the om2008.8 image.

So I guess, in the long run, I'll be aiming to provide a kernel patchset 
specifically for the freerunner hardware in the portage tree, as well as 
a toolchain patchset for the samsung sc324XX SoC that the openmoko folks 
are using. It should be possible to build everything that the openmoko 
folks provide in any of their images, given a list of packages & the 
patchsets, but using the (far better IMHO) ebuild build system as 
opposed to bitbake.

Nedd & Angelo - with the PDA-centric overlay ( & binary packages? ) that 
you guys are creating, are there any plans in the works for making a 
(graphical?) package manager app for mobile devices? I'm using 
portage-utils pretty extensively these days for a push-ing distributed 
package manager, which my boss has me unfortunately implementing as a 
grails web-app, but I'd be very interested in collaborating on something 
like that, gtk-based, ncurses-based, written in Java for all I care, etc.

Cheers,

Chris

The binary packages available here
(http://tinderbox.dev.gentoo.org/embedded/linwizard/) are targeted for 
armv5te-softfloat-linux-gnueabi

Yes, we have plans to change the package managers available in
{GPE,openmoko,...} to support our .tbzs instead of ipkg.
For now, I'm just more worried in getting a emergeable openmoko and GPE
tree into the overlay.

One of the problems that miknix has run into so far is that the
openmoko-appmanager depends on ipkg and friends. There was some talk of
recoding/hacking on that one to make it portage-utils aware. Feel free
to discuss that further with him.

In the freerunner they are using the sc32440 for this generation of the
phone right? It should only be minor kernel patching required. But I'd
rather us not have an explicit openmoko-sources as I'm using the sc324xx
chips myself.

I'm not sure why you would have to provide any toolchain patches.
Everything works as of today the the misc CHOST's the device can use.

armv4tl-softfloat-linux-gnueabi / arm-softfloat-linux-gnueabi /
arm-softfloat-linux-uclibc etc....

Hmm... will do.

The FreeRunner uses the sc32442B. The only thing I don't really like 
with the openmoko-kernel at least, is that they've jammed board info 
into /proc/cpuinfo instead of /proc/SBC/info.

e.g.

$ cat /proc/cpuinfo | tail -n 3
Hardware	: GTA02
Revision	: 0350
Serial		: 0000000000000000

Personally, I think that belongs in /proc/SBC/info, so that's the only 
patch that I would make, although it would probably make some waves in 
the rest of the openmoko community/stack.

> I'm not sure why you would have to provide any toolchain patches.

Cool - I just remember how difficult it was to get the ep93xx / maverick 
fpu working. The FreeRunner has no dedicated on-or-off-chip FPU so 
softfloat it is.

Although I'm sure that if the SMedia 3362 driver source code was 
available, that the graphics processor could double as an FPU. That 
would definitely require some toolchain hacking - so maaaaybe I'll 
forget about it ... for now.

Look, for example, at qpkg.c source on portage-utils which Ned is one
of the authors.

why not the regular place ?  tinderbox is a blackhole.  plus, the normal infra

Re: [gentoo-embedded] openmoko overlay?

[Christopher Friedt]

Right now I'm working on getting Android up and running on my OpenMoko
Freerunner.

Has anyone else on the list checked it out?

My strategy right now is to translate a handful of opcodes found in
the >= ARMv5 ISA into equivalent ARMv4 ISA sequences and then add any
hardware-specific libs for the FreeRunner, as necessary. One thing I'm
really wondering about is how performance will compare (if at all)
between the s3c2442 and something like the msm7201, given that the
s3c2442 lacks the DSP cores. Is the s3c2442 really up to the task of
running Android?

I've got a page going here:

http://wiki.openmoko.org/wiki/Android

There are also a few sources for Android-compatible kernel patches at
the moment.

Cheers,

Chris

Someone tried something very similar and eventually admitted defeat,
but wrote a stunning tech article on their efforts at emulating the
missing instructions in the kernel
http://benno.id.au/blog/2007/11/21/android-neo1973
Enjoy! I did!

That was before android was open-sourced. You may now be able to
compile it for armv4t

Right, Benno is also helping out - check out the android-porting list ;-)

Since the source code has been released (http://source.android.com),
it's no longer necessary to emulate the missing instructions in-kernel
- we can code in the equivalent ARMv4T instructions :)
