gdbserver-igfx "failed to initialize"

[eric_d_]

Hello,

I'm trying to use OpenCL™ Kernel Debugger as explained here: https://software.intel.com/en-us/node/671873
I have a target as follow:

• Ubuntu 16.04LTS
• Intel Celeron J3160
• Intel® SDK for OpenCL™ Applications 2016 R3
• Intel driver for OpenCL - intel-opencl-xxx-r3.0-57406.x86_64
• intel graphic driver i915 v 4.7.0.intel.r3.0

My problem:
When I use following command:
/usr/bin/gdbserver-igfx :1234 --attach 123

I get error "Failed to initialize"

I tried several things like adding the HOST IP address, starting the program first to put a real PID, ... But nothing worked.

Please Help !

As I've tried to replicate this behavior, what has caused this for me is attempting to run on an unsupported processor.  It looks like your hardware is also not on the supported list for the SDK.  For more info on supported hardware please see the release notes.

Hi Jeffrey,

Well here is a copy/past of https://software.intel.com/en-us/intel-opencl

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

New: Intel® SDK for OpenCL™ Applications 2016 R3 is now available for download. This update adds support for new OSes and platforms, more performance analysis features and various SDK improvements.

• New Platforms: 7^th Generation Intel® Core™ Processor, 7^th Generation Intel® Celeron® Processor J3000 Series, 7^th Generation Intel® Pentium® Processor J4000 Series, 7^th Generation Intel® Celeron® Processor N3000 Series, 7^th Generation Intel® Pentium Processor N4000 Series

Do you  mean that "Intel Celeron J3160" is not part of "J3000 Series" ?

[Jeffrey_M_Intel1]

You're right that the J3160 is part of the J3000 series.  However, the GPU for that one is Intel HD Graphics 400.  This is the same GPU architecture as 5th Generation Core processors, not 7th Generation.  

For more info: http://www.notebookcheck.net/Intel-HD-Graphics-400-Braswell.169243.0.html

The Celeron and Pentium processors supported by the current SDK are part of the "Formerly known as Apollo Lake" products, as listed here: http://ark.intel.com/products/codename/80644/Apollo-Lake#@All

We're working on clarifying the summary on the landing page. Thanks for your helpful feedback on this.

Okay, that's clear.

Thank you for your support.
