Memory Allocation Profiling
Memory allocation profiling is available in UEK 8U2. This feature tracks memory allocation to help when reviewing where memory is used and when tracking down memory leaks. The feature uses code tagging to track where memory was allocated, when allocated memory is freed, the number of allocations, and the amount of memory still in use.
The option is disabled by default but can be enabled at boot by using the boot parameter:
sysctl.vm.mem_profiling=1You access runtime information for memory allocation profiling in
/proc/allocinfo.
See https://docs.kernel.org/mm/allocation-profiling.html for more information. Note that the compressed option for memory allocation profiling isn't available in UEK 8U2.
