|
* Description
|
|
* The Hardware Composer (HWC) Commit test is a benchmark that
|
|
* discovers the points at which the HWC will commit to rendering an
|
|
* overlay(s). Before rendering a set of overlays, the HWC is shown
|
|
* the list through a prepare call. During the prepare call the HWC
|
|
* is able to examine the list and specify which overlays it is able
|
|
* to handle. The overlays that it can't handle are typically composited
|
|
* by a higher level (e.g. Surface Flinger) and then the original list
|
|
* plus a composit of what HWC passed on are provided back to the HWC
|
|
* for rendering.
|
|
*
|
|
* Once an implementation of the HWC has been shipped, a regression would
|
|
* likely occur if a latter implementation started passing on conditions
|
|
* that it used to commit to. The primary purpose of this benchmark
|
|
* is the automated discovery of the commit points, where an implementation
|
|
* is on the edge between committing and not committing. These are commonly
|
|
* referred to as commit points. Between implementations changes to the
|
|
* commit points are allowed, as long as they improve what the HWC commits
|
|
* to. Once an implementation of the HWC is shipped, the commit points are
|
|
* not allowed to regress in future implementations.
|
|
*
|
|
* This benchmark takes a sampling and then adjusts until it finds a
|
|
* commit point. It doesn't exhaustively check all possible conditions,
|
|
* which do to the number of combinations would be impossible. Instead
|
|
* it starts its search from a starting dimension, that can be changed
|
|
* via the -s option. The search is also bounded by a set of search
|
|
* limits, that are hard-coded into a structure of constants named
|
|
* searchLimits. Results that happen to reach a searchLimit are prefixed
|
|
* with >=, so that it is known that the value could possibly be larger.
|
|
*
|
|
* Measurements are made for each of the graphic formats specified as
|
|
* positional parameters on the command-line. If no graphic formats
|
|
* are specified on the command line, then by default measurements are
|
|
* made and reported for each of the known graphic format.
