From: Sourab Gupta <sourab.gupta@intel.com>
There's a need for an interface which provide information about GFX
memory usage per process, at any instantaneous point of time.
Such information is useful to analyze GFX memory usage of the processes,
on the lines of other system memory usage tools (e.g. procrank).
This is especially useful for the GFX intensive processes, since the
tools such as procrank may not be able to provide a precise view of
GFX memory consumption, with its specific intricacies (such as
differentiation between private, shared and purgeable buffers).
The patch provides a sysfs interface to list GFX memory usage for
each client process. The interface also provides GFX buffers/memory
usage information categorized into various buckets according to buffer
type such as purgeable, private, shared.
v2:
-Move from per drm file accounting to per process accounting to
address shared drm fd cases (Daniel)
-Use div64_u64 for 64 bit divisions (Sagar)

From: Sourab Gupta <sourab.gupta@intel.com>
There are some GFX buffers e.g. ringbuffers, ctx buffers, etc. which
are not associated with any drm fd. Thus, the sum of the shmem memory
consumed by processes would be less than the total memory actually
consumed in the system.
This patch keeps track of all shmem memory consumptions in the system
which is given out by the sysfs interface introduced earlier.

From: Sourab Gupta <sourab.gupta@intel.com>
Sometimes, in order to debug the mem usage scenarios, the summarized
view of GFX memory consumption per process is not sufficient, as it
doesn't provide buffer level details. Therefore, there's a need for an
interface, which can provide such detailed information.
This patch provides a sysfs interface to retrieve such detailed information
about GFX buffers used per process. Each process has a sysfs file
associated in the 'gfx_memtrack' directory, named by the process' tgid.
Reading the file will provide list of all GFX buffers open by the process,
along with their attributes such as size, pinneed, tiling, shared,
allocstate, gtt offset, etc.

This patch adds the functionality to output the virtual addresses
of each GFX buffer, mapped into process address space (via interfaces
such as mmap and mmap_gtt).

From: Sourab Gupta <sourab.gupta@intel.com>
The GFX memory consumed by a process is not accounted by kernel. This
leads to a scenario wherein the low memory killer is not able to
correctly identify the best process to be killed during OOM scenarios.
This case particularly manifests when an application has a large GFX
memory footprint but has a significantly smaller system mem consumption.
Low mem killer in such a case will not be able to identify this culprit
process, and lot of innocent process will be killed without freeing much
memory.
This patch utilizes the memtracker functions to add the accounting for
the processes' GFX memory consumption.
The internal kernel counters updated thus don't affect the output of
procrank, meminfo or smaps.
The kernel counters updated though would lead to better approximation
of process' memory consumption, leading to better low mem killer behavior.
The memtracker functions are called at asynchronous points during
shrinker invocation.
Thus, in times of memory stress, we ensure to update the processes' GFX
mem statistics, therefore leading to better low mem killer behavior
