[Pkg-opencl-devel] Bug#781875: beignet: kernels don't seem to run

[Giuseppe Bilotta]

Package: beignet-opencl-icd
Version: 1.0.2-1
Severity: grave
Tags: upstream

Since version 1.0.1 beignet has been able to recognitze the hardware on
my machine

00:02.0 VGA compatible controller [0300]: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller [8086:0416] (rev 06)

and responds regularly to device info queries as well as buffer
allocation commands. However, kernels don't seem to run at all, in any
form and with any queue properties. Buffers return untouched.

Discussion with people on #opencl indicate that the bug:

* affects upstream;
* only occurs when using beignet through the ICD interface;
* has been introduced _probably_ somewhere between 1.0.0 and 1.0.1.

It also seems that the issue cannot be noticed by simply running the
beignet tests, since they link directly to the library.
