emulator support in 2.6.27 ?

[Don Mullis]

Don't see any commits of goldfish code in the android-2.6.27 branch of
kernel/common.git, yet. Will the emulator be supported in 2.6.27?

thanks,
D

Yes it will, I've ported the patches about a month ago and got the emulator booting we have not pushed it yet. I haven't tried booting it recently. I think once we stabilize the msm branch we'll push goldfish.

It seems the emulator cant boot current release still, right ? Is
there any plan to push goldfish ?

thanks

Hopefully very soon, the team is just getting back from the holiday season.

Need emulator support for new kernel. Please, we're working on it...

I think it's coming soon. If not in the next push, it'll probably be
in the one after that.

The latest 2.6.27 goldfish kernel is now available:
http://android.git.kernel.org/?p=kernel/common.git;a=shortlog;h=refs/heads/android-goldfish-2.6.27

We'll be keeping this goldfish branch(es) up to date in the
kernel/common tree from here on out.

Hi,
I am not familiar with git.
I do not know to how to switch from refs/heads/android-2.6.27 to refs/
heads/android-goldfish-2.6.27.
Could you tell me how to use git command to get android-
goldfish-2.6.27 ?

Thanks a lot,

Leon

There are _many_ tutorials on the web which will help you resolve this
problem. Have you tried reading them?

Just checkout the remote android-goldfish-2.6.27 branch. This can be
done in a variety of different ways, but the most common would be:

git checkout -t origin/android-goldfish-2.6.27 -b goldfish

which would create a local branch called goldfish and check it out and
cause it to track the upstream goldfish branch.

good luck,

Hello,

I've checked out the goldfish branch and have built using the arch/arm/
configs/goldfish_defconfig .config file, the prebuilt arm-eabi
toolchain, and ARCH set to arm. However, running the emulator with
the custom kernel does not work:

$ emulator -kernel arch/arm/boot/zImage

The emulator remains at the "Android..." screen. For about a minute
after launching the emulator, "adb devices" returns "emulator-5554
offline" after which adb does not find any devices. I would
appreciate any help regarding what I should do to get the emulator to
boot a custom kernel.

Thank you.

Perhaps you need the -system argument to the emulator. So after
building Android and the kernel tree, I do something like this:

$ out/host/linux-x86/bin/emulator -kernel kernel/arch/arm/boot/zImage -
system out/target/product/generic/

Hi Greg,
Thank for your help.
I did try finding the solution by myself.
I think that I will spend more time to understand git.
Git seems quit different compared to CVS and SVN.

Thanks,

Leon

Thanks Bryne. The -system argument is just what I needed.

With the following steps i am able to start the emulator successfully,
but the emulator screen gets locked.I am able to use adb shell.

Can anyone help in this regard...??
Thanks in advance......!!!

Compiling Android kernel sources for getting kernel-image for the
emulator

(1) Get the Android Kernel latest sources

(2) Get toolchains from CodeSourcery (Choose ARM GNU/Linux and IA32
GNU/Linux)

(3) Untar the toolchain and the android kernel sources

(4) Start the Android emulator (go to the android-sdk directory and
start the emulator)

# ./emulator

(5) Get the config.gz from the running emulator using ‘adb’

# ./adb pull /proc/config.gz .

(6) Decompress the config.gz and rename it to .config

# gunzip config.gz
# mv config .config

(7) Replace the old .config in the android kernel sources with the
above .config file

(8) Specify the CROSS_COMPILE path in the Makefile of android kernel
sources

(9) Comment out LDFLAGS_BUILD_ID in the same Makefile
# LDFLAGS_BUILD_ID = $(patsubst -Wl$(comma)%,%,\
$(call ld-option, -
Wl $(comma)--build-id,))

(10) Issue the make command for the kernel
# make menuconfig ARCH=arm (just check and uncheck anything, but
don’t forget to save the config)
# make ARCH=arm

(11) Kernel image will be created at arch/arm/boot/zImage

(12) You can start the emulator by issuing the following command(go to
the android-sdk directory and start the emulator)

# ./emulator –kernel ../arch/arm/boot/zImage -show-kernel -shell

I have done a little bit different from what you did,
1. instead of to get toolchain from CodeSourcery, I get it from the
prebuild directory of android source
2. get the goldfish by:
git-clone git://android.git.kernel.org/kernel/common.git

git checkout -t origin/android-goldfish-2.6.27 -b goldfish

3. make ARCH=arm CROSS_COMPILE=<my toolchain> goldfish_defconfig
4. make ARCH=arm CROSS_COMPILE=<my toolchain> zImage
