SWITCHING A WIRELESS DISPLAY MODE AND REFRESHING A GRAPHICS PROCESSING UNIT IN AN UNSTABLE STATE

摘要

Various aspects of the present disclosure provide for detecting a condition indicating that a graphics processing unit (GPU) is in an unstable state while receiving GPU commands in a first wireless display mode, transmitting a GPU refresh request message and switching from the first wireless display mode to a second wireless display mode in response to detecting the condition, receiving data sufficient to reset the GPU from the unstable state to a stable state at a random access point (RAP) in a trace of the GPU commands, and switching from the second wireless display mode to the first wireless display mode after receiving the data. The GPU refresh request message may include information requesting the data sufficient to reset the GPU at an upcoming RAP in the trace of the GPU commands. Various other aspects are also provided throughout the present disclosure.

主权项

1. An apparatus configured for wireless display, the apparatus comprising:
a transceiver; a memory; a graphics processing unit (GPU); and at least one processor communicatively coupled to the transceiver, the memory, and the GPU, wherein the at least one processor and the memory are configured to:
detect a condition indicating that the GPU is in an unstable state while in a first wireless display mode;in response to detecting the condition, transmit a GPU refresh request message and switch from the first wireless display mode to a second wireless display mode;after transmitting the GPU refresh request message, at a random access point (RAP) in a trace of GPU commands, receive data sufficient to reset the GPU from the unstable state to a stable state; andswitch from the second wireless display mode to the first wireless display mode after receiving the data.
