The Dynamic RAM Console is an alternative to Android ram-console and pstore console that does not require a dedicated memory region for its operation. It continually captures all console messages and stores them in a small dynamically allocated circular buffer in RAM. The content of this buffer persists across reboots and is available as /proc/kmsg.last.
