    Abstract: An operation method of an electronic device is provided. A busy-waiting instruction indicating that the operating system of the processing device is in a busy-waiting state is received. The processing device is in a virtual machine mode. A microcode of the busy-waiting instruction is obtained according to the registered value of the first register. The waiting enabling instruction is generated, and the first counting value corresponding to the waiting enabling instruction and the second counting value corresponding to the first system time are obtained according to the microcode. The first and second counting values are added to generate a third counting value and store it in a second register. According to the waiting enabling instruction, a subsequent microcode is stopped sending to the processing device, so that the processing device enters an idle state, and the counter is enabled to start counting according to the third counting value.

  • Patent number: 12518723
    Abstract: Embodiments of the present disclosure relate to a method for controlling a Vsync signal, an electronic device, a storage medium, and a chip. The method includes: A synthesis system receives a Vsync signal request message sent by a main thread of an application. After receiving the Vsync signal request message, the synthesis system determines a number of rendering times of a rendering thread of the application in unit time. When the number of rendering times of the rendering thread in unit time is equal to the system refresh rate of an electronic device, a Vsync thread sends a Vsync signal to the main thread of the application at a first frequency, and the first frequency is equal to the system refresh rate.

  • Publication number: 20250383764
    Abstract: This application relates to the field of image processing technologies, and provides an image presentation method, an electronic device, a storage medium, and a chip. The method may include: After an upper-layer application completes drawing a buffer, SurfaceFlinger (SF) does not need to wait for a Vsync signal, but immediately composes the buffer drawn by the upper-layer application, and a display driver sends the composed buffer to a display for display after receiving the Vsync signal. To avoid accumulation of the composed buffer, the method may further include: After the upper-layer application completes drawing the buffer, when a composed buffer has not yet been displayed, the SF stops a current composition and disables the Vsync signal sent to the SF. In addition, the SF takes the latest buffers for composition and discards the older buffers when composing buffers.

  • Patent number: 12430163
    Abstract: The present invention relates to a method for a processor and a computer system to enter system management mode (SMM). The method is applied to the processor, which includes at least one logical core. The method includes entering the SMM in response to a system management interrupt (SMI), storing current state information to a corresponding state save area; setting operation mode to target operating mode, and executing the SMI handler under the target operating mode. The address of the state save area, the address of the core configuration information memory space, and the address of the SMI handler can be determined directly. Each logical core may enter the target operating mode directly through hardware setting every time after entering the SMM, and thus does not need to perform a fixed operation of mode switching when executing the SMI handler, which may improve the execution efficiency of the SMI handler.

  • Publication number: 20250181391
    Abstract: The present application relates to the technical field of system management mode (SMM), and in particular it relates to a control method, a processor, and a computer system for system management mode. The method is applied to a processor. The processor includes at least one logical core. The method performs an initialization setting before each logical core enters system management mode. The initialization setting includes: allocating system management random access memory (SMRAM) required in the SMM to each logical core; and storing addresses related to the SMRAM of each logical core into at least one model-specific register MSR. There is no need to set SMRAM for each logical core serially. This shortens the time spent on initialization in the SMM and improves the execution efficiency of initialization.
