* Fix bug of clEnqueueCopyBufferToImage and clEnqueueCopyImageToBuffer.Yan Wang2017-05-255-28/+89
| | | | | | | | | | | | | | "imagedim_non_pow_2" cases of basic modudle of confrmance shows regression after use TILE_Y mode for large image by previous patch. This bug comes from the non-align16 kernel of clEnqueueCopyBufferToImage and clEnqueueCopyImageToBuffer. It will force CL_RGBA/CL_UNORM_INT8/8191x8192 image of conformance test to CL_R/CL_UNSIGNED_INT8/32764x8192 image for copying. So it makes width as 8191 x 4 = 32764 and its width will exceed the maximum width (16 x 1024 = 16384) of GEN surface state structure which only has 14 bits. So use align4 copy kernel to avoid this bug. Signed-off-by: Yan Wang <yan.wang@linux.intel.com>
