|
* \brief Abstract class for measuring shader operator performance.
|
|
*
|
|
* This class draws multiple times with different workload sizes (set
|
|
* via a uniform, by subclass). Time for each frame is measured, and the
|
|
* slope of the workload size vs frame time data is estimated. This slope
|
|
* tells us the estimated increase in frame time caused by a workload
|
|
* increase of 1 unit (what 1 workload unit means is up to subclass).
|
|
*
|
|
* Generally, the shaders contain not just the operation we're interested
|
|
* in (e.g. addition) but also some other stuff (e.g. loop overhead). To
|
|
* eliminate this cost, we actually do the stuff described in the above
|
|
* paragraph with multiple programs (usually two), which contain different
|
|
* kinds of workload (e.g. different loop contents). Then we can (in
|
|
* theory) compute the cost of just one operation in a subclass-dependent
|
|
* manner.
|
|
*
|
|
* At this point, the result tells us the increase in frame time caused
|
|
* by the addition of one operation. Dividing this by the amount of
|
|
* draw calls in a frame, and further by the amount of vertices or
|
|
* fragments in a draw call, we get the time cost of one operation.
|
|
*
|
|
* In reality, there sometimes isn't just a trivial linear dependence
|
|
* between workload size and frame time. Instead, there tends to be some
|
|
* amount of initial "free" operations. That is, it may be that all
|
|
* workload sizes below some positive integer C yield the same frame time,
|
|
* and only workload sizes beyond C increase the frame time in a supposedly
|
|
* linear manner. Graphically, this means that there graph consists of two
|
|
* parts: a horizontal left part, and a linearly increasing right part; the
|
|
* right part starts where the left parts ends. The principal task of these
|
|
* tests is to look at the slope of the increasing right part. Additionally
|
|
* an estimate for the amount of initial free operations is calculated.
|
|
* Note that it is also normal to get graphs where the horizontal left part
|
|
* is of zero width, i.e. there are no free operations.
