+===================================
+GPU cgroup controller
+===================================
+
+Goals
+=====
+This document intends to outline a plan to create a cgroup v2 controller subsystem
+for the per-cgroup accounting of device and system memory allocated by the GPU
+and related subsystems.
+
+The new cgroup controller would:
+
+* Allow setting per-cgroup limits on the total size of buffers charged to it.
+
+* Allow setting per-device limits on the total size of buffers allocated by a
+  device/allocator within a cgroup.
+
+* Expose a per-device/allocator breakdown of the buffers charged to a cgroup.
+
+Alternatives Considered
+=======================
+
+The following alternatives were considered:
+
+The memory cgroup controller
+____________________________
+
+1. As was noted in [1], memory accounting provided by the GPU cgroup
+controller is not a good fit for integration into memcg due to the
+differences in how accounting is performed. It implements a mechanism
+for the allocator attribution of GPU and GPU-related memory by
+charging each buffer to the cgroup of the process on behalf of which
+the memory was allocated. The buffer stays charged to the cgroup until
+it is freed regardless of whether the process retains any references
+to it. On the other hand, the memory cgroup controller offers a more
+fine-grained charging and uncharging behavior depending on the kind of
+page being accounted.
+
+2. Memcg performs accounting in units of pages. In the DMA-BUF buffer sharing model,
+a process takes a reference to the entire buffer(hence keeping it alive) even if
+it is only accessing parts of it. Therefore, per-page memory tracking for DMA-BUF
+memory accounting would only introduce additional overhead without any benefits.

+
+Userspace service to keep track of buffer allocations and releases
+__________________________________________________________________
+
+1. There is no way for a userspace service to intercept all allocations and releases.
+2. In case the process gets killed or restarted, we lose all accounting so far.
+
+UAPI
+====
+When enabled, the new cgroup controller would create the following files in every cgroup.
+
+::
+
+        gpu.memory.current (R)
+        gpu.memory.max (R/W)
+
+gpu.memory.current is a read-only file and would contain per-device memory allocations
+in a key-value format where key is a string representing the device name
+and the value is the size of memory charged to the device in the cgroup in bytes.
+
+For example:
+
+::
+
+        cat /sys/kernel/fs/cgroup1/gpu.memory.current
+        dev1 4194304
+        dev2 4194304
+
+The string key for each device is set by the device driver when the device registers
+with the GPU cgroup controller to participate in resource accounting(see section
+'Design and Implementation' for more details).
+
+gpu.memory.max is a read/write file. It would show the current total
+size limits on memory usage for the cgroup and the limits on total memory usage
+for each allocator/device.
+
+Setting a total limit for a cgroup can be done as follows:
+
+::
+
+        echo “total 41943040” > /sys/kernel/fs/cgroup1/gpu.memory.max
+
+Setting a total limit for a particular device/allocator can be done as follows:
+
+::
+
+        echo “dev1 4194304” >  /sys/kernel/fs/cgroup1/gpu.memory.max
+
+In this example, 'dev1' is the string key set by the device driver during
+registration.
+
+Design and Implementation
+=========================
+
+The cgroup controller would closely follow the design of the RDMA cgroup controller
+subsystem where each cgroup maintains a list of resource pools.
+Each resource pool contains a struct device and the counter to track current total,
+and the maximum limit set for the device.
+
+The below code block is a preliminary estimation on how the core kernel data structures
+and APIs would look like.
+
+.. code-block:: c
+
+        /**
+         * The GPU cgroup controller data structure.
+         */
+        struct gpucg {

+                struct list_head rpools;
+        };
+
+        struct gpucg_device {
+                /*

+                 * part of.

+                struct list_head rpools;
+                /* list of all devices registered for GPU cgroup accounting */
+                struct list_head dev_node;
+                /* name to be used as identifier for accounting and limit setting */

+        };

+                struct list_head dev_node;
+
+                /* tracks memory usage of the resource pool */
+                struct page_counter total;
+        };
+

+        void gpucg_register_device(struct gpucg_device *gpucg_dev, const char *name);
+
+        /**

+        void gpucg_uncharge(struct gpucg *gpucg, struct gpucg_device *device, u64 usage);
+
+Future Work
+===========
+Additional GPU resources can be supported by adding new controller files.
+
+Upstreaming Plan
+================
+* Decide on a UAPI that accommodates all use-cases for the upstream GPU ecosystem
+  as well as for Android.
+
+* Prototype the GPU cgroup controller and integrate its usage into the DMA-BUF
+  system heap.
+
+* Demonstrate its usage from userspace in the Android Open Space Project.
+
+* Send out RFCs to LKML for the GPU cgroup controller and iterate.
