- Add a klogd to collect the kernel logs and place them into a new kernel log buffer - Parse priority, tag and message from the kernel log messages. - Turn off pruning for worst UID for the kernel log buffer - Sniff for 'PM: suspend exit', 'PM: suspend enter' and 'Suspended for' messages and correct the internal definition time correction against monotonic dynamically. - Discern if we have monotonic or real time (delineation 1980) in audit messages. - perform appropriate math to correct the timestamp to be real time - filter out any external sources of kernel logging Change-Id: I8d4c7c5ac19f1f3218079ee3a05a50e2ca55f60d |

The properties that logd responds to are:
name type default description
logd.auditd bool true Enable selinux audit daemon
logd.auditd.dmesg bool true selinux audit messages duplicated and
sent on to dmesg log
logd.klogd bool depends Enable klogd daemon
logd.statistics bool depends Enable logcat -S statistics.
ro.config.low_ram bool false if true, logd.statistics & logd.klogd
default false
ro.build.type string if user, logd.statistics & logd.klogd
default false
persist.logd.size number 256K default size of the buffer for all
log ids at initial startup, at runtime
use: logcat -b all -G <value>
persist.logd.size.main number 256K Size of the buffer for the main log
persist.logd.size.system number 256K Size of the buffer for the system log
persist.logd.size.radio number 256K Size of the buffer for the radio log
persist.logd.size.event number 256K Size of the buffer for the event log
persist.logd.size.crash number 256K Size of the buffer for the crash log
NB:
- number support multipliers (K or M) for convenience. Range is limited
to between 64K and 256M for log buffer sizes. Individual logs override the
global default.
