llkd: moved from optional to required component The Live Lock Killer Daemon (llkd) has provided enough hero moments to improve system stability, by providing actionable collection of data to resolve kernel, and some user space, misbehaviors. It is time to move llkd to a required component. NB: For llkd to be effective at finding real kernel live lock conditions, system requirements are that there are no more un-waited for Zombie processes, and that no kernel drivers use indeterminate periods of uninterruptible sleep. Any kernel and user space tasks that are killed because of suspicious behavior, must themselves have a benefactor to restart them if necessary. If a true live lock is discovered, data will be collected and the kernel will be panic'd to recover from the situation. Signed-off-by: Mark Salyzyn <salyzyn@google.com> Bug: 164946924 Test: llkd is ever present on a release build. Change-Id: I986a8545252bc5b68d09a6a0f4f506a58998c8a0
This is the Makefile-based portion of the Android Build System.
For documentation on how to run a build, see Usage.txt
For a list of behavioral changes useful for Android.mk writers see Changes.md
For an outdated reference on Android.mk files, see build-system.html. Our Android.mk files look similar, but are entirely different from the Android.mk files used by the NDK build system. When searching for documentation elsewhere, ensure that it is for the platform build system -- most are not.
This Makefile-based system is in the process of being replaced with Soong, a new build system written in Go. During the transition, all of these makefiles are read by Kati, and generate a ninja file instead of being executed directly. That's combined with a ninja file read by Soong so that the build graph of the two systems can be combined and run as one.
