Intelligent management of application layer rendering

A method of a render manager of a display system, the method comprising:

• receiving one or more render sync requests from one or more application layers;
• choosing, for each render sync request, a render sync signal from a plurality of render sync signals, each render sync signal of the plurality of render sync signals defining a render sync event that periodically repeats;
• and
• sending, for each render sync request, a render sync response to an application layer which sent that render sync request, the render sync response comprising a render sync signal indicator configured to indicate the chosen render sync signal,
• wherein for each application layer, an occurrence of the chosen render sync signal determines a render start time defining a time in which rendering of a surface associated with that application layer is allowed to start, and
• wherein the one or more render synch requests are separate from renderings performed by the one or more application layers.

A render manager of a display system, comprising:

• means for receiving one or more render sync requests from one or more application layers;
• means for choosing, for each render sync request, a render sync signal from a plurality of render sync signals, each render sync signal of the plurality of render sync signals defining a render sync event that periodically repeats;
• and
• means for sending, for each render sync request, a render sync response to an application layer which sent that render sync request, the render sync response comprising a render sync signal indicator configured to indicate the chosen render sync signal,
• wherein for each application layer, an occurrence of the chosen render sync signal determines a render start time defining a time in which rendering of a surface associated with that application layer is allowed to start, and
• wherein the one or more render synch requests are separate from renderings performed by the one or more application layers.

A non-transitory computer-readable medium storing computer-executable instructions for a render manager of a display system, the computer-executable instructions comprising:

• one or more instructions instructing the render manager to receive one or more render sync requests from one or more application layers;
• one or more instructions instructing the render manager to choose, for each render sync request, a render sync signal from a plurality of render sync signals, each render sync signal of the plurality of render sync signals defining a render sync event that periodically repeats;
• and
• one or more instructions instructing the render manager to send, for each render sync request, a render sync response to an application layer which sent that render sync request, the render sync response comprising a render sync signal indicator configured to indicate the chosen render sync signal,
• wherein for each application layer, an occurrence of the chosen render sync signal determines a render start time defining a time in which rendering of a surface associated with that application layer is allowed to start, and
• wherein the one or more render synch requests are separate from renderings performed by the one or more application layers.
