- * The Memory Tracker HAL is designed to return information about
- * device-specific memory usage.
- * The primary goal is to be able to track memory that is not
- * trackable in any other way, for example texture memory that is allocated by
- * a process, but not mapped in to that process's address space.
- * A secondary goal is to be able to categorize memory used by a process into
- * GL, graphics, etc. All memory sizes must be in real memory usage,
- * accounting for stride, bit depth, rounding up to page size, etc.
- *
- * Constructor for the interface should be used to perform memtrack management
- * setup actions and is called once before any calls to getMemory().

-     * A process collecting memory statistics will call getMemory for each
-     * combination of pid and memory type. For each memory type that it
-     * recognizes, the HAL must fill out an array of memtrack_record
-     * structures breaking down the statistics of that memory type as much as
-     * possible. For example,
-     * getMemory(<pid>, GL) might return:
-     * { { 4096,  ACCOUNTED | PRIVATE | SYSTEM },
-     *   { 40960, UNACCOUNTED | PRIVATE | SYSTEM },

-     * If the HAL cannot differentiate between SYSTEM and DEDICATED memory, it
-     * could return:
-     * { { 12288,  ACCOUNTED | PRIVATE },
-     *   { 49152,  UNACCOUNTED | PRIVATE } }
-     *
-     * Memory must not overlap between types. For example, a graphics buffer
-     * that has been mapped into the GPU as a surface must show up when
-     * GRAPHICS is requested and not when GL
