SRU Justification:
[Impact]
Enable the Android modules ASHMEM and BINDER_IPC in the Azure kernel.
[Fix]
See attached patch for config changes. Set CONFIG_ANDROID=y, CONFIG_ASHMEM=m,
CONFIG_BINDER_IPC=m
[Test Case]
1. Installed the kernel deb, linux-modules, and linux-modules-extra.
2. Booted the test kernel.
3. sudo modprobe ashmem_linux
Checked dmesg for errors
4. sudo modprobe binder_ipc_linux
Checked dmesg for errors.
[Where problems could occur]
Though the Android subsystem is in staging, enabling ANDROID=y appears to be a
standalone operation.
There should be no impact until the Android modules are manually installed.

Title:
Azure kernel for focal misses binder and ashmem kernel modules
Status in linux-azure package in Ubuntu:
New
Status in linux-azure source package in Focal:
New
Bug description:
For the purpose of Anbox Cloud we package both the binder and ashmem
kernel modules in the Ubuntu kernel. The generic kernel ships it and
all clouds specific kernels should too. However the azure kernel
doesn't include the prebuilt binder_linux.ko and ashmem_linux.ko
modules:
ubuntu@ac0:~$ uname -r
5.4.0-1039-azure
ubuntu@ac0:~$ dpkg -L linux-modules-extra-5.4.0-1039-azure | grep binder
ubuntu@ac0:~$ dpkg -L linux-modules-extra-5.4.0-1039-azure | grep ashmem
Can we please get both kernel modules added to azure kernel and at the
same time double check that the modules are packaged in all other
cloud kernels?
Thanks!
