* Fix a build problem when the llvm version has the fix version digit.Zhigang Gong2013-11-271-1/+1
| | | | | | | | | | If the llvm version is something like 3.3.1, the previous cmake script will generate an incorrect cflags as: -DLLVM_33 1 which breaks the build. This commit also update the stable llvm version from 3.1 to 3.3. Signed-off-by: Zhigang Gong <zhigang.gong@intel.com> Reviewed-by: Yang Rong <rong.r.yang@intel.com>

* GBE/Runtime: implement workaround for IVB sampler bugZhigang Gong2013-09-261-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Per IVB spec, If the surface format of the associated surface is UINT or SINT, the Surface Type cannot be SURFTYPE_3D or SURFTYPE_CUBE and Address Control Mode cannot be CLAMP_BORDER or HALF_BORDER. Besides this bug, there is another undocumented issue. If a surface data type is IEEE float. Then when we use sampler to sample the pixel, if the value is betweeo -1p-20 to 0, the sampler will rounding it to zero. And this will also bring problem when we are using the clamp mode. This patch is to workaround the above two hardware issues. It introduces a new intrinsic get_sampler_info to get a sampler type at runtime. When calling to read_image, it will check whether it hits the above two cases. If it hit case 1, then we will force it to use clamp to edge for those pixels within the box, And for those pixel out of the box, we manually set the border color. To achieve this solution, we have to prepare two sampler slot for each CL_ADDRESS_CLAMP sampler. And the first has slot_1 which is using CL_ADDRESS_CLAMP, the second use slot_1 + 8. Thus we can only use half of 16 samplers. Fortunately, 8 samplers comply with the OpenCL's minimal requirement. If it hits case 2, then we minor a epsilon to the coordinate, and let it not rounds to zero. If possible, programer should avoid to use float coordinates and/or int/uint format image. Otherwise, it will hit the very slow path. With this workaround, the compiler_copy_image1 can pass now.

* Implement KHR ICD extensionSimon Richter2013-04-181-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | This adds a pointer to the dispatch table at the beginning of every object of type - cl_command_queue - cl_context - cl_device_id - cl_event - cl_kernel - cl_mem - cl_platform_id - cl_program - cl_sampler as required by the ICD specification. The layout of the dispatch table comes from the OpenCL ICD loader by Brice Videau <brice.videau@imag.fr> and Vincent Danjean <Vincent.Danjean@ens-lyon.org>. To avoid dispatch table entries being overwritten with the ICD loader's implementations of the CL functions (as would be the proper behaviour for the ELF loader), the -Bsymbolic option is given to the linker.

* Implement cl_khr_gl_sharing by using upstream technology.Zhigang Gong2013-04-101-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | The previous implementation use a modified mesa library and can't work with upstream mesa. Now I managed to use existing egl extension and gbm to import a gl texture to a cl image. Actually, the gbm can't fully support our purpose, as it can't lookup image for egl x11 platform. We have to touch gbm's internal data structure to manually initialize its image extension. Furthermore, gbm only provide the API to get the image's handle, and doesn't provide the one to get image's name. As we are using different fd from the existing GL loader. The handle is useless for us. I use the DRI2 image extension function directly to get the name rather than the handle. And it works well. Now, after this patch applied. The cl_khr_gl_sharing could work with upstream mesa. I recommend you use the latest git master version.
