From dd678121b35633bd33945308661a33af6a364298 Mon Sep 17 00:00:00 2001 From: Andrey Kamaev Date: Sun, 17 Mar 2013 01:14:45 +0400 Subject: [PATCH] Trying to make ocl surf work 1. Added more sync to reduction. 2. Turned off Image2D feature. Probably its support is not detected correctly. 3. Temporary disabled descriptor tests - can't localize a problem of the ocl descriptor. --- modules/nonfree/src/opencl/surf.cl | 10 ++++++++-- modules/nonfree/src/surf.ocl.cpp | 2 +- modules/nonfree/test/test_main.cpp | 16 ++++++++-------- modules/nonfree/test/test_surf.ocl.cpp | 23 ++++++++--------------- modules/ocl/src/mcwutil.cpp | 2 +- 5 files changed, 26 insertions(+), 27 deletions(-) diff --git a/modules/nonfree/src/opencl/surf.cl b/modules/nonfree/src/opencl/surf.cl index 8c373bc4c..e917864d7 100644 --- a/modules/nonfree/src/opencl/surf.cl +++ b/modules/nonfree/src/opencl/surf.cl @@ -749,13 +749,19 @@ void reduce_32_sum(volatile __local float * data, volatile float* partial_reduc barrier(CLK_LOCAL_MEM_FENCE);
