Setup account

1. Create account

If you are using VMware, you might need to add a new account. DO NOT use the “mine” account, and it is suggested to use your Domain_ID.

sudo useradd -d /home/[Domain_ID] -m -g [group] [Domain_ID]
sudo passwd [Domain_ID]

Example:

sudo useradd –d /home/yanglin3 –m –g adm yanglin3
sudo passwd yanglin3

2. Generate ssh-key

ssh-keygen -t rsa
cat ~/.ssh/id_rsa.pub

3. Register gerrit

Refer to Gerrit manual: gerrit_manual.pptx

4. Apply permission (VMware user only)

If you are not working on Nanjing Site, you might need to apply the permission to access Qualcomm Baseline code. Send the content of your id_rsa.pub to huangrongfu@yulong.com.

Example:

This is XXX from shenzhen site, who is working on 8860U product BSP team.
Can you help to add me permission to access Baseline code, my ssh-key is:
#ssh-rsa .....

5. Install git and Setup .gitconfig

Git: already installed by default in linux

Run the following commands to config the .gitconfig (you can find the file under ~/.gitconfig)
(Replace the <Name>, <Email>, <Domain_ID> to your own information)

git config --global color.ui auto
git config --global core.editor vim
git config --global --add user.name <Name>  
git config --global --add user.email <Email>

Example

git config --global color.ui auto
git config --global core.editor vim
git config --global --add user.name "Tiger Huang"
git config --global --add user.email huangrongfu@yulong.com

(Optinal) For Nanjing guys who uses the linux machine, and has skipped Setup account 4. Apply permission (VMware user only), run one more command:

git config --global --add url.file:///njyjs.insteadof ssh://njyjs@10.5.41.69/njyjs

(Optinal) If you are not using the Domain_ID as your linux accout, you might need to run

git config --global --add url.ssh://<Domain_ID>@10.1.11.21:29418.insteadof ssh://10.1.11.21:29418
Example: your account is /home/yl20186, but Domain_ID is huangrongfu
git config --global --add url.ssh://huangrongfu@10.1.11.21:29418.insteadof ssh://10.1.11.21:29418

6. Install repo

Download the repo tool, run

git clone ssh://njyjs@10.5.41.69/njyjs/qualcomm/repo -b yl20186 ~/bin/repo

add the repo into you PATH:
Example:

add "export PATH=~/bin/repo:$PATH" into you ~/.bashrc (add to last line)

yanglin3@git-server:~/bin<203>$ bash
yanglin3@git-server:~/bin<1>$ which repo
/home/yanglin3/bin/repo/repo

For the repo/git usage, the details refer to http://source.android.com/source/developing.html

Download code

1. repo init

Download the manifests according to your working group

2. repo sync

Download the source code

repo sync -j4

3. Create debug remote (Optional)

If you need to push code to debug branches and haven't run this command before:

repo forall -c 'git remote rm yl.dbg; git remote add yl.dbg apksync@10.1.11.21:qcom/$REPO_PATH'

This command will create remote yl.dbg for each repo.

4. Doanload modem code (staled, unused now)

If you are working on modem team, you can try the following command to download the source code:

git clone ssh://apksync@10.1.11.21:29418/qcom8930_BP/qcom8930_modem -b yulong8930

Build commands

THE FOLLOWING CMDS ARE JUST EXAMPLES

CP7576U

./build.sh cp7576u -v eng -b P1
./build.sh cp7576u -v eng -b P1 -i bootimg

CP8860U

./build.sh cp8860u -r vf_it -b T3 -v user -u
./build.sh cp8860u -b T3 -i bootimg
./build.sh cp8860u -b T3 -i aboot

CP8861U

./build.sh cp8861u -b T3 -v user -u

CP8870U

./build.sh cp8870u -b P1 -v user -u

Modify code

create your local branch and jump to it

git checkout -b <local_branch>

modify your code (Remember not enable encryption software)
add your changes to index

git add .

commit the changes

git commit -s

If this commit is for submitting to gerrit, you need to make sure you commit message following the gerrit rules.

  ActivityID:Sumitter Title
  <blank line>
  Detail description about why you add this commit
  <blank line>
  Signed-off

Example:

  AndDB00655899:huangrongfu Fix hotplug attribute during the suspend failure
  
  If the system suspend fails, the hotplug_disable attribute remains
  set. This prevents any change to core status from mpdecision. Reset
  the value of this attribute if the module receives PM_POST_RESTORE
  notification.

Submit code

Submit to Gerrit

After you have completed your coding, you need to submit it to gerrit for review.

8930

git push yl.sz <local_branch>:refs/for/yl_8930_4.2

8210

git push yl.sz <local_branch>:refs/for/yl_8210_4.4

Resubmit to Gerrit

Most time, the reviewer would have comments on your code, then you might need to modify your code (git commit -s –amend)and resubmit the change.

git push yl.sz <local_branch>:refs/changes/<gerrit_number>

Example

http://10.1.11.21:8081/#/c/131/
git push yl.sz <local_branch>:refs/changes/131

Push to Debug branch

There are some branches which can be used for test/debug.

yl_8860u_apk (app team)
yl_8860u_debug (system team)
yl_8860u_driver (driver team)
yl_8860u_plt
yl_8860u_radio

Let me take the yl_8860u_driver branch for example to explain how to push to it.

1, Fetch and rebase to the debug branch
  > git fetch yl.dbg
  > git checkout remotes/yl.dbg/yl_8860u_driver
2, Apply your changes
3, Push to debug branch
  > git push yl.dbg <local_branch>:yl_8860u_driver
