An experiment: Sony Xperia S and AOSP

An experiment: Sony Xperia S and AOSP Jean-Baptiste Queru 8/14/12 12:35 PM
I'm going to try an experiment.

Over time, AOSP has added files related to various hardware targets.
We started with just a few scripts on a web page (1.0), then we had a
git project (Cupcake), then we released some of the exact source files
that were used on retail flagship devices (Froyo), then distributed
proprietary binaries (Gingerbread), then we were able to run on
PandaBoard (Ice Cream Sandwich).

For a new challenge, I'd like to try to go one step further, and to
target some hardware beyond the usual categories. I've added a git
project for the Sony LT26, i.e. Xperia S. This seems like a good
target: it's a powerful current GSM device, with an unlockable
bootloader, from a manufacturer that has always been very friendly to
AOSP.

That git project is currently empty. I'm open to suggestions about the
best way to populate it. I think I'll start by putting together a
skeleton set of makefiles, followed by a kernel. Contributions are
strongly encouraged, and there should be more freedom than usual to
submit experimental changes since that won't impact the devices that
Google is most directly involved in.

I don't know how far that'll go, and there are so many unknowns that
the only way to know is to try it.

As usual, please be very careful about handling any proprietary files,
for Xperia S or any other device. Don't copy them, use them, or
distribute them without an appropriate license. Obviously, don't
upload them to AOSP if you don't own them. When in doubt, please ask
ahead of time, it's easier to answer an email than to fix things in an
emergency.

TL;DR: For a long while this'll probably only be useful for low-level
engineering, but won't be usable as a daily driver.

In theory, AOSP is designed such that it should be possible to plug in
the files related to additional hardware targets. In practice, that
has never happened.

The short-term goal is to investigate the difference between theory
and practice, on a favorable real-world example, and to see whether
the result is worth the effort. The long-term goal is to try to
eliminate whatever hurdles we find, both the expected and the
unexpected ones.

I expect that we'll need at least a few iterations before that can
become usable as a day-to-day phone, and it's unclear whether that'll
ever happen. There's a reasonable chance that it could be useful for
people working at a lower level, literally several layers below the UI
and applications that everyone is familiar with. If you've seen the
classic Android Architecture diagram, we're going to be in the kernel
and just above it.

I don't want to use the word "supported" because there's no way to
agree on a single unambiguous definition.

Hi

What would be the main differences between the CM device target and the AOSP device target ?
Re: [android-building] Re: An experiment: Sony Xperia S and AOSP Jean-Baptiste Queru 8/15/12 8:18 AM
Hi Andreas,

I've submitted my skeleton, with the caveat that it's very bare.

Beware that there's no actual kernel (I've put an empty file in its
place). My next step is to get the real kernel sources in AOSP and to
build my own kernel.

I think the other urgent step is to get a proper BoardConfig.mk in
there. You probably have something suitable.

I'm not incredibly worried about recovery (yet). I guess I'm biased,
since I only work on devices with unlocked bootloaders, so I'm used to
relying solely on fastboot.

Well, assuming that we can get to the same level of hardware support
(which is challenging on the AOSP side), we'd obviously have a
slightly different feature set.

I expect that the biggest difference might be more on the philosophy:
while CM is more likely to focus on stability, being based on a stable
tagged release, my work in AOSP is more likely to aim for the bleeding
edge, by using the master branch.

Re: [android-building] Re: An experiment: Sony Xperia S and AOSP Giulio Cervera 8/15/12 4:31 PM
For what i guessed Sony source is based on Arpil/March CAF code for
ICS, and CAF code is based on October/November 2011 AOSP

Sony kernel can be considered more stable, but is not designed for JB

The big difference of CM JB branch is what CAF userspace code can be
used. Few example can be the video dec/enc or the vsync'ed composition
which require updated kernel.

CM is "cherry picked" from various sources including but not limited to improvements donated by community. Since I do not have Xperia S, I can't say what exactly, but as a CM nightly user, I can say it would be the right "bleeding edges" AOSP desperately needs.

For one thing, CM kernel would likely be more open to change then Sony's unmodified

Re: [android-building] Re: An experiment: Sony Xperia S and AOSP Jean-Baptiste Queru 8/20/12 7:59 AM
The answer will depend on the success of the project :)

In all seriousness, we're made enough progress already to get us to
the point where we're facing the harder problems:
-making changes in the common Android tree that aren't actually
necessary for the devices that Google works on.
-handling the proprietary files.
-restoring the device to its factory state.

I see that as good news. That means that we've already taken care of a
number of smaller problems. Those also don't surprise me, from my
experience managing other devices in AOSP, and so far we haven't hit
any unforeseen hurdle.

Re: [android-building] Re: An experiment: Sony Xperia S and AOSP Jean-Baptiste Queru 8/20/12 8:29 AM
As far as end-users are concerned, the potential end result that could
be visible would be upgrades arriving very slightly earlier for Sony
devices, for two reasons:

-it could make the Android tree slightly more friendly to Sony devices
by merging changes that are specifically needed for those devices.

-by providing a concrete support for discussions, it could help Sony
engineers better organize their work to match the way Google engineers
work.

Now, that's entirely speculative, there's definitely now way to
quantify how big a difference this could make or when it would start
to be visible.

Just so that I get the right kernel, which defconfig should I be using?

I'm going to guess fuji_nozomi_defconfig for now, but I'd like confirmation.

Re: [android-building] Re: An experiment: Sony Xperia S and AOSP Giulio Cervera 8/21/12 2:43 PM
correct, it's mostly stock sony defconfig whit jb changes from tuna_defconfig

just to make u aware, sony bootloader have some issue and sometime boot fail
we have guessed about certain boot.img size broke boot, change compression
or add a filler file to make the image smaller or bigger fix the issue

also boot partition is very big (20MB) and i would recommend to use
uncompressed
kernel image

Re: [android-building] Re: An experiment: Sony Xperia S and AOSP Jean-Baptiste Queru 11/8/12 8:07 AM
Your commands are correct.

You can also turn your 4.0.4 client into a master one, with "repo init
-b master" in that client (followed by repo sync, of course).

master is bleeding edge, so it's ahead of Jelly Bean.

This indicates that you haven't actually synced and checked out
the current master of external/e2fsprogs, because the reference
to LOCAL_MODULE_STEM that make complains about was removed in
commit dc3069a about a year ago. The most recent commit in that
git should be 5886dc5, and that's the commit you should have
checked out. Try this (and post the output):

cd external/e2fsprogs
git rev-parse HEAD
repo sync .
git branch -a | grep remotes/m/
git rev-parse HEAD

If you look in the Android.mk files below external/e2fsprogs, is
LOCAL_MODULE_STEM set for any shared library module (actually,
anything but executable or host executable)? Show the output of the
following commands (run from the e2fsprogs root):

git status
grep LOCAL_MODULE_STEM */*.mk

It looks like your source workspace is okay. I don't have time to help
you any further. You should get to the bottom of which module it's
actually complaining about (e.g. by commenting out parts of the
makefiles, piece by piece until it stops yelling) and take it from
there.

6.1.A.0.452 is ICS-based and won't work out of the box with the
JB-based master branch. Unless you really know what you're doing

What do you mean, did you get the build problems when including the
source code from Sony's 6.1.A.0.45[234] drop? That would explain the
build error but wouldn't explain why Git reported external/e2fsprogs
to be clean and have the correct commit checked out.

No, the master branch contains Jellybean and some other stuff. You can
assume that the master branch is always ahead of anything on release
branches.

The master branch is closer to Jellybean than to ICS. You need the
master branch to get the device configuration, but the code that Sony's
released is for ICS. Yes, this makes things harder. You either have to
retrofit the LT26 setup from the master branch to an ICS branch (sounds
pretty easy) or use the ICS-based Sony software on top of Jellybean.

You can't just copy the files. You'd have to figure out what Sony has
done in those directories and apply the same patches to a Jellybean
tree. They've changed about 80 files in the Webkit tree but I don't
think they've made any significant changes anywhere and probably none
that are necessary for the phone to boot. The reason those directories
are included in the archive is because they're under GPL or LGPL.

Then you didn't restore the original tree.

An ICS kernel might work, it depends on the actual kernel changes
between ICS and JB. It might be possible to apply the changes between
the stock ICS kernel and Sony's ICS kernel onto the stock JB kernel,
but that probably wouldn't be a trivial task.

Sony hasn't released any JB-based kernel sources. I think they've
announced that JB updates for their phones will be released during
Q1 2013, so I wouldn't expect kernel sources to be publicly available
prior to that.

You can also do this by adding the lt26.git in a local manifest file, as described in the README on the github project [1].  Then when you repo sync it will automatically fetch it for you.

The boot.img format for LT26 does not conform to the Google standard, so there need to be extra processing of this file. This was prior to the 4.2 merge temporally taken care of by https://android-review.googlesource.com/#/c/41360/

Someone mentioned that Intel need a similar patch, so it would make sense to look at the raised concerns and try to get this patch into the tree.

For now you can cherry-pick this patch (minor conflict though).

This will make it possible to flash the partitions and power on the device. Unfortunately the graphics stack is updated, so with the current set of gralloc and adreno binaries we're missing https://android-review.googlesource.com/#/c/42485/ and the "legacy" variant of SurfaceComposerClient::getDisplayInfo().

By cherry picking #42485 and reverting (the revert) 38b657265ccc5ae45bd7860a68b0d9373b47a2f3 you can get the device to boot.

We're looking at sorting these things out in a proper way so that we can publish updated source and binaries.

Regards,
Bjorn

Hello,

i have seen the anouncement here:

So I want to build and flash the same image in my Xperia S.

I currently have a 6.1.A.0.452 image.

I have built everything, starting from master branch, thansk to explanations from https://github.com/sonyxperiadev/device-sony-lt26

the flash of userdata is ok:
out/target/product/lt26]$ fastboot flash userdata userdata.img
sending 'userdata' (35508 KB)...
(bootloader) USB download speed was 30351kB/s
OKAY [  1.214s]
writing 'userdata'...
(bootloader) Flash of partition 'userdata' requested
(bootloader) S1 partID 0x00000009, block 0x0029f000-0x0069efff
(bootloader) Erase operation complete, 0 bad blocks encountered
(bootloader) Flashing...
(bootloader) Flash operation complete
OKAY [  4.948s]

on the otherhand, the flashall freezes immediatly, during the flash of the boot.img

Even when I try to execute " fastboot flash boot boot.img ", it freezes (I have waited for 30min, hope it is enough...).

Would you have an explanation/solution for such freeze ?
