[Beignet] double precision support

[Malcolm Roberts]

Hello.

I just installed the latest version of beignet from git 
(74390cabe5d2958fec5806a5099bad44c74798f5) and I notice that cl_khr_fp64 
is not available.  I am a bit late for the conversation in July 
(http://lists.freedesktop.org/archives/beignet/2014-July/003599.html) 
but I thought that I would add my voice.

I have a project to do scientific computation using the OpenCL platform, 
and double precision is vital for my work.  I understand that the 
beignet teams has limited resources and that one must prioritize, but I 
feel that double-precision would be a great addition.

Best,
