  1. Disconnect the device
  2. Execute "adb kill-server"
  3. Reconnect the device
  4. Run "adb devices"

If these steps do not help, restart the system and then run "adb devices" again. You may also need to consult product documentation for your device to see if a custom USB driver needs to be installed on devices based on Intel architecture and third-party ARM*-based devices.

Known Issues and Limitations

General

  • Your system must be connected to the internet while you are installing Intel GPA.
  • Selecting all ergs might cause a significant memory usage in Graphics Frame Analyzer.
  • Intel® GPA uses sophisticated techniques for analyzing graphics performance which may conflict with third-party performance analyzers. Therefore, ensure that other performance analyzers are disabled prior to running any of these tools. For third-party graphics, consult the vendor's website.
  • Intel® GPA does not support use of Remote Desktop Connection.
  • Graphics Frame Analyzer (DirectX* 9,10,11) runs best on systems with a minimum of 4GB of physical memory. Additionally, consider running the Graphics Frame Analyzer (DirectX* 9,10,11) in a networked configuration (the server is your target graphics device, and the client running the Graphics Frame Analyzer is a 64-bit OS with at least 8GB of memory).
  • On 64-bit operating systems with less than 8GB of memory, warning messages, parse errors, very long load times, or other issues may occur when loading a large or complex frame capture file.

Analyzing Android* Workloads

  • Graphics Frame Analyzer does not currently support viewing all OpenGL/OpenGL ES* texture formats.
  • Intel® GPA provides limited support for analyzing browser workloads on Android*. You can view metrics in the System Analyzer, but the tools do not support creating or viewing frame capture files or trace capture files for browser workloads. Attempting to create or view these files may result in incorrect results or program crashes.
  • Intel® GPA may fail to analyze OpenGL* multi-context games.
  • If you want to profile Android* workloads from an OS X* system, make sure to install Platform Analyzer.
    If you choose not to install Platform Analyzer, you are recommended to disable tracing support in System Analyzer. Press Crtl+F1 in the System Analyzer Connection window and deselect the “Enable tracing on Android devices” checkbox.

Analyzing Windows* OS Workloads

  • Texture 2x2 experiment might work incorrectly for some DirectX 12 workloads.
  • Overdraw experiment for Render Targets with 16-bit and 32-bit Alpha channel is not supported now.
  • To view Render Targets with 16-bit and 32-bit Alpha channel you should disable Alpha channel in the Render Targets viewer.
  • DirectX 12.1 API is not supported now.
  • To ensure accurate measurements on platforms based on Intel® HD Graphics, profile your application in the full-screen mode. If windowed mode is required, make sure only your application is running. Intel® GPA does not support profiling multiple applications simultaneously.
  • For best results when analyzing frame or trace capture files on the same system where you run your game, follow these steps:
    • Run your game and capture a frame or trace file.
    • Shut down your game and other non-essential applications.
    • Launch the Intel® GPA.
  • To run Intel® GPA on hybrid graphics solutions (a combination of Intel Processor Graphics and third-party discrete graphics), you must first disable one of the graphics solutions.
  • Secure Boot, also known as Trusted Boot, is a security feature in Windows* 8 enabled in BIOS settings which can cause unpredictable behavior when the "Auto-detect launched applications" option is enabled in Graphics Monitor Preferences. Disable Secure Boot in the BIOS to use the auto-detection feature for analyzing application performance with Intel® GPA. The current version of the tools can now detect Secure Boot, and will warn you of this situation.
  • To view the full metric set with the tools for Intel Processor Graphics on systems with one or more third-party graphics device(s) and platforms based on Intel® HD Graphics, ensure that Intel is the preferred graphics processor. You can set this in the Control Panel application for the third-party hardware. Applications running under Graphics Monitor and a third-party device show GPU metrics on DirectX* 9 as initialized to 0 and on DirectX* 10/11 as unavailable.
  • When using the Intel® GPA, disable the screen saver and power management features on the target system running the Graphics Monitor — the Screen Saver interferes with the quality of the metrics data being collected. In addition, if the target system is locked (which may happen when a Screen Saver starts), the connection from the host system to the target system will be terminated.
  • Intel® GPA does not support frame capture or analysis for:
    • applications that execute on the Debug D3D runtime system
    • applications that use the Reference D3D Device
  • System Analyzer HUD may not operate properly when applications use copy-protection, anti-debugging mechanisms, or non-standard encrypted launching schemes.
  • Intel® GPA provides analysis functionality by inserting itself between your application and Microsoft DirectX*. Therefore, the tools may not work correctly with certain applications which themselves hook or intercept DirectX* APIs or interfaces.
  • Intel® GPA does not support Windows* 8 OS Store Applications where the graphics API uses compositing techniques such as HTML5 or XAML interop.  Only traditional DirectX* rendering is supported. To workaround this limitation, port your application as a Desktop application, and then use the full Intel GPA suite of tools.
  • In some cases, the Overview tab in Graphics Frame Analyzer (DirectX* 9,10,11) can present GPU Duration values higher than Frame Duration values measured during game run time. This could be a result of Graphics Frame Analyzer (DirectX* 9,10,11) playing the captured frame back in off-screen mode which can be slower than on-screen rendering done in the game.

    To make playback run on-screen use this registry setting on the target system: HKEY_CURRENT_USER\Software\Intel\GPA\16.3\ForceOnScreenPlaybackForRemoteFA = 1 and connect to the target with Graphics Frame Analyzer (DirectX* 9,10,11) running on a separate host. If these requirements are met, the playback will run in off-screen mode on the target. If the frame was captured from the full-screen game, but playback renders it in a windowed mode, then try to press Alt+Enter on the target to switch playback to full-screen mode.

  • Frame capture using Graphics Monitor runs best on 64-bit operating systems with a minimum of 4GB of physical memory.
    On 32-bit operating systems (or 64-bit operating systems with <4GB of memory), out of memory or capture failed messages can occur.
  • A defect in the Unity* 4 Integration with Oculus PC SDK ver. 0.5 prevents proper capture in Unity VR titles. Only Oculus* hardware is verified. Other VR devices might work but have not been tested.

Analyzing Ubuntu* Workloads

  • Tracing functionality is currently not supported for Ubuntu* targets.
  • GPU metrics for Ubuntu* targets are available on Intel HD Graphics 2500/4000 platforms only. 
  • When analyzing frames for Unigine Heaven* and Valley* benchmarks on systems with 4th Generation Intel Core™ Processors, edit /etc/drirc configuration file to set the flags for the local player to the exact values that Unigine uses for this application. For example: 

    <application name="" executable="glesplayer">
                <option name="force_glsl_extensions_warn" value="true" />
                <option name="disable_blend_func_extended" value="true" />
                <option name="force_glsl_version" value="130" />
                <option name="disable_shader_bit_encoding" value="true" />
                <option name="allow_glsl_extension_directive_midshader" value="true" />
    </application>

    Otherwise, Graphics Frame Analyzer may fail to play the frame correctly.
