|

* 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.
|

|

* This function must be thread-safe, it may get called from multiple
|
||||
* threads at the same time.
|
||||
*
|
||||
* 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 },
|
||||
* { 8192, ACCOUNTED | PRIVATE | DEDICATED },
|

* { 8192, UNACCOUNTED | PRIVATE | DEDICATED } }
|

* 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
|
||||
* is requested.
