Sung-hun Kim [Thu, 16 Jul 2020 06:58:28 +0000 (15:58 +0900)]
mm: LKSM: new feature: use filter-based scanning to reduce scanning cost

LKSM_FILTER is a new feature which is intended to reduce the computation cost.
LKSM_FILTER exploits bitmap-based filters to skip scanning of unnecessary
pages. To this end, LKSM collects addresses of shared pages to make filters.

The rationale of LKSM_FILTER is that user-level programs share common runtime
framework and libraries. Because of that processes can have similar address
space layout. It means that if a page is merged with another page, the same
virtual address in different process can be merged with this merged page.
In this regard, KSM can use a single global filter to cover all sharable areas
in the system.

The challenge is caused by a secure construct of Linux kernel, namely ASLR.
ASLR enforces to have randomized address space for each process, and it
severely disrupts making a global filter.

To overcome this challenge, LKSM exploits two information: regions and offsets.
A region means the physically mapped area. Each process has its own VMAs but
they may mapped same files. A region means the original one.
An address space of a process is randomized in the unit of VMA. It means that
if pages are merged even in the different virtual addresses, there can be at
same offsets from individual VMAs.

LKSM leverages both regions and offsets to construct per-region filters.
By using per-region filters, LKSM could effectively reduce its scanning space
and also computation cost by up to 46% against previous version of LKSM at the
expense of somewhat sharing chances.

Sung-hun Kim [Thu, 16 Jul 2020 00:05:12 +0000 (09:05 +0900)]
mm: LKSM: lightweight memory deduplication for embedded devices

Lightweight KSM (in short, LKSM) is a variant of KSM that is implemented in
a fully event-triggered manner. LKSM provides a memory deduplication facility
like vanilla KSM while it extremely reduces overhead.

Normally, LKSM is blocked and waits for incoming deduplication requests from
user-level process (e.g., resourced). When a user-level process submits
deduplication request via sysfs, LKSM performs requested-level of deduplication,
such as partial and full deduplications.
After that, LKSM is going to sleep again and waits for next request coming.

By doing so, LKSM mitigates side effects that impact on system performance,
for instance, occupying system resources such as CPU and incurring cache
pollutions.

scripts: mkbootimg_rpi4.sh: Fix how to check 64bit

The CONFIG_64BIT_TIME configuration is used by 32bit kernel, so it is
having problem identifying 64bit. So modify to "CONFIG_64BIT=y".
