[Beignet] cl_get_gt_device(): error while running OPenCL on Kabylake
Hi , i get the following error when i try to run some opencl benchmark on Kabylake. How can i fix this? cl_get_gt_device(): error, unknown device: 5916 error calling clGetDeviceIDs The same works on older intel families. Is there a support missing for Kabylake/.? ___ Beignet mailing list Beignet@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/beignet
Re: [Beignet] [PATCH V2 5/6] Backend: Add intel_sub_group_shuffle_down/up/xor
The first 4 patches is LGTM, will push them. For intel_sub_group_shuffle_down/up implement, we'd better handle it in the opencl c level. > -Original Message- > From: Beignet [mailto:beignet-boun...@lists.freedesktop.org] On Behalf Of > Xiuli Pan > Sent: Thursday, July 7, 2016 11:10 > To: beignet@lists.freedesktop.org > Cc: Pan, Xiuli > Subject: [Beignet] [PATCH V2 5/6] Backend: Add > intel_sub_group_shuffle_down/up/xor > > From: Pan Xiuli > > Using a function shuffle delta for down/up, using some flags for current and > down/up src switch.

Re: [Beignet] [Patch V2] intel: Export pooled EU and min no. of eus in a pool.
