auto: Let the emulator choose between hardware or software graphicsĪcceleration based on your computer setup.The value of mode can be set to one of the following Line, include the -gpu option, as shown in the following example:Įmulator -avd avd_name -gpu mode To specify a graphics acceleration type when you run an AVD from the command Select a value for the Graphics: option.Ĭonfigure graphics acceleration from the command line.Window, find the Emulated Performance section. To configure graphics acceleration for an AVD, follow these steps: SDK Platform: Latest release recommended (Android 4.0.3, Revision 3, minimum)Ĭonfigure graphics acceleration in the AVD Manager.Latest release recommended (version 17 minimum) To use graphics acceleration, your development environment must have the The graphics acceleration setting in the AVD for that virtual device instance. Uses software acceleration (using your computer's CPU) to simulate GPU If your GPU hardware andĭrivers are compatible, the emulator uses the GPU. Graphics acceleration based on your computer setup. Uses graphics drivers that aren't compatible with the emulator.īy default, the emulator decides whether to use hardware or software However, you might need to use software acceleration if your computer Hardware acceleration is recommended and is typicallyįaster. Specify whether the emulator uses hardware or software to emulate When you create an Android Virtual Device (AVD) in the AVD Manager, you can (OpenGL ES or GLES) for rendering both 2D and Android devices use OpenGL for Embedded Systems Graphics acceleration uses your computer's hardware (typically the GPU) to make Virtual machine (VM) acceleration to get higher performance from the emulator. If it isn'tĮnabled on your machine, this page describes how you can configure graphics and Hardware acceleration is enabled by default on most machines. Virtual machine (VM) acceleration for improved execution speed.Graphics acceleration for improved screen.The emulator can use hardware acceleration to improve your Your machine’s hardware to improve performance is called hardware The CPU, GPU, and modem, rather than running as pure software. As PC resides in kernel space, the training branches TJ and TC will trigger page faults, which we recover from.The emulator runs best if it can use your machine’s hardware, such as Upon execution of PC, the CPU will thus recursively inject RSB predictions to disclosure gadget G, whose location immediately follows the PHANTOMCALL at PC. The target of this training call at is set to PC, establishing a recursive PHANTOMCALL prediction. In training step T2, the attacker executes a training call at TC that collides with PC in the BTB, which will establish the prediction for the PHANTOMCALL. The target of the PHANTOMJMP is set to PC, at which the recursive PHANTOMCALL will be triggered. The victim return VR is allocated after PJ in the control flow. Residing in the kernel address space, PJ is the address that initiates the recursive PHANTOMCALL. "In the first training step T1, the attacker executes a training branch at TJ, which collides with the BTB entry of PHANTOMJMP source PJ. BTB is the Branch Target Buffer and RSB is the Return Stack Buffer.
