Google has shared extra particulars about the way it goals to convey the Android kernel so much closer to the mainline Linux kernel with the impending launch of Android 12.The information got here courtesy of a presentation at the Linux Plumbers Conference by Google’s software program engineer Todd Kjos.Commenting on the improvement, Ars Technica shares that usually the mainline Linux kernel goes via three main forks earlier than it is shipped to the finish customers on an Android system.The fragmentation isn’t only a large time sink, which often means Android gadgets ship Linux kernels which can be no less than a few years outdated, but in addition complicate the supply course of for safety updates and bug fixes.Reducing forksIn order to admire Google’s new initiative, Ars explains that historically all the stakeholders in the Android ecosystem fork the Linux kernels in an assembly-like vogue.. First up is Google, which forks the mainline kernel into “Android widespread” including Android-specific adjustments. This is then forked by System-On-Chip (SoC) distributors like Qualcomm, and Samsung, to create SoC-specific kernels. Finally, a device-specific fork on the SoC kernel is created and shipped with a tool.Sharing the change in strategy, Kjos mentioned that “the large push is to get all of the hardware-specific code out of the generic kernel and into vendor modules.” A significant a part of this effort, shared Kjos, is the improvement of a steady interface between vendor-specific modules and the generic kernel. This new interface, often called the Kernel Module Interface (KMI), will be certain that the “foremost distinction” between the Android Generic Kernel Image (GKI) and mainline Linux, are simply the hooks for all of the vendor-specific modules.While Google reportedly plans to ship the GKI with the upcoming Android 12 launch, Kjos known as the whole initiative “a multi-year challenge” as he laid out a timeline for the subsequent few years of kernel work.Via Ars Technica
