Abstract | One disclosed method includes registering a graphics buffer with a kernel running on a first processor, storing the registered graphics buffer in memory initially without drawing the graphics buffer to a display, and passing the registered graphics buffer to a kernel display driver directly to draw the graphics buffer to the display, in response to a trigger. The method may further include informing a second processor of the registered graphics buffer and receiving the trigger by the kernel as a message from the second processor. The first processor may receive the trigger as a wake command from the second processor while the first processor is in sleep mode. A partial resume of the kernel is then performed while preventing activation of user space on the primary processor, and the graphics buffer is drawn on the display without using an operating system graphics pipeline of the user space. |
