drm/v3d: Add gpu_gem_info node via debugfs

Add gpu_gem_info node via debugfs of dri debug sysfs for each
process with pid/tgid and its gem objects. Same gem object can be
opened from multiple processes, so from the gpu_gem_info node,
it can print same gem in multiple lines.

Ported from the commit dea4ace78ec7 ("drm/vc4: Add gem_info node
via debugfs") to v3d.

NOTE: From Raspberry Pi 4 board, v3d gpu is card0 and also render node
in dri card128, so accessing can be from both nodes. For render fixed
node, it is /sys/kernel/debug/dri/128/gpu_gem_info.
Also, Raspberry Pi 4 board gives entire gem count and total size with
/sys/kernel/debug/dri/128/bo_stats.

mm: LKSM: fix a bug in the filter length calculation

Since type of a size variable in the calculation of the
filter length is signed integer, it can make a buggy
situation when the size of a vma is bigger than a range
of a signed integer variable. In this case, the size is
treated as a negative number. As a result, it incurs a
kernel bug at BUG_ON(size < 0).

This patch changes types of variables and members in
lksm_region data structure from signed integer to unsigned
long. Additionally, remove an assertion BUG_ON(size < 0)
because the size never be a negative number.

mm: LKSM: bug fix for kernel memory leak

For efficiency, LKSM cleans exited processes in a batched manner when it
finishes a scanning iteration. When it finds exited process while it is in
the scanning iteration, it just pends the mm_slot of the exited process to
the internal list.

On the other hend, when KSM daemon cleans mm_slots of exited processes, it
should care regions of exited processes to remove unreferenced lksm_region
objects.

Previously, most regions are maintained properly but only regions in "head"
of the exited process list does not be cleaned due to the buggy implementation.
At last, uncleaned objects are remained as unreferenced garbages.

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.

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.
