Description

Building on the Treble and Generic System Image work, Android is
further pushing the boundaries of upgradibility and modularization with
a fairly ambitious goal: Generic Kernel Image (GKI). With GKI, Android
enablement by silicon vendors would become independent of the Linux
kernel running on a device. As such, kernels could easily be upgraded
without requiring any rework of the initial hardware porting efforts.
Accomplishing this requires several important changes and some of the
major topics of this year's Android MC at LPC will cover the work
involved. The Android MC will also cover other topics that had been the
subject of ongoing conversations in past MCs such as: memory, graphics,
storage and virtualization.

Proposed topics include:

Generic Kernel Image
ABI Testing Tools
Android usage of memory pressure signals in userspace low memory killer
Testing: general issues, frameworks, devices, power, performance, etc.
DRM/KMS for Android, adoption and upstreaming dmabuf heaps upstreaming
dmabuf cache managment optimizations
kernel graphics buffer (dmabuf based)
SDcardfs
uid stats
vma naming
vitualization/virtio devices (camera/drm)
libcamera unification
These talks build on the continuation of the work done last year as reported on the Android MC 2018 Progress report. Specifically:

Symbol namespaces have gone ahead
There is continued work on using memory pressure signals for uerspace low memory killing
Userfs checkpointing has gone ahead with an Android-specific solution
The work continues on common graphics infrastructure
If you are interested in participating in this microconference and have topics to propose, please use the CfP process. More topics will be added based on CfP for this microconference.
