Extend test coverage for `clClonekernel` by jainvikas8 · Pull Request #1251 · KhronosGroup/OpenCL-CTS

jainvikas8 · 2021-05-14T16:22:05Z

Add the following test coverage for the clCloneKernel

With args:
Use clSetKernelArg to set args after kernel is cloned. Enqueue and
read the buffer to validate.

With Execinfo:
Use clSetKernelExecInfo after the kernel is cloned and read the buffer
to validate.

With no args:
Clone a kernel with no args and enqueue.

With SVM pointer:
Use clSetKernelArgSVMPointer to set args after kernel is cloned.
Enqueue and read the buffer to validate.

This fixes #1098 and #1234

This PR also replaces test_error with test_assert_error to report the error during failure.

I had the same issue on another PR. I ended up re-pushing (on the same branch) to retrigger another run. Hopefully there's a more clever alternative with a simple button to press somewhere, but I couldn't find it.

Hi @jainvikas8
I've check your changes on Windows on Intel GPU and I am getting
ERROR: clFinish failed! (CL_OUT_OF_RESOURCES from C:\NewVPG\Repo\public-github\opensource-qb\OpenCL-CTS\test_conformance\api\test_clone_kernel.cpp:524) test_exec_enqueue_helper failed for cloneKernel_2 on retry. clCloneKernel test_cloned_kernel_exec_info failed. clone_kernel FAILED

The test process is not able to exit looks like hang. Could you double check on your side if everything is ok ? I will analyze the problem as well.

Have not observed this in the past, normally it should fail for this too.

@gwawiork I've been unable to reproduce this issue on MALI-GPU in Linux with OpenCL 2.1 and 3.0. So, please let me know your thoughts on this?

test_conformance/api/test_clone_kernel.cpp

+        clSVMFree(context, svmPtr_srcKernel_1);
+
+        // enqueue - cloneKernel_1 again, to check if the args were not modified
+        if (test_exec_enqueue_helper(context, queue, pBuf, svmPtr_cloneKernel_1,


From this point on, pBuf still contains pointer to svmPtr_srcKernel_1.
Since test_exec_enqueue_helper does not update the pBuf, the cloneKernel_1 will receive an invalid pointer as argument.

The pointer inside pBuf needs to be updated before enqueuing the kernel.

I have moved clSVMFree to free the buffers in the end.

ddabek-i · 2021-11-17T13:10:59Z

test_conformance/api/test_clone_kernel.cpp

+    error = clFinish(queue);
+    test_error(error, "clFinish failed");


This clFinish should not be needed, since clEnqueueSVMMap is made blocking by passing it CL_TRUE as the second argument.

ddabek-i · 2021-11-17T13:22:03Z

test_conformance/api/test_clone_kernel.cpp

+                                            "set_kernel_exec_info_kernel");
+        test_error(error, "Unable to create srcKernel");
+
+        BufPtr* pBuf =


It looks like the same structure pBuf will be passed to each kernel (as a pointer) and only the pBuf->store will be updated before enqueuing each kernel. Not sure if this is intended?

@ddabek-i It is indeed intended. We use it to test clSetKernelexecinfo with clCloneKernel

ddabek-i · 2021-11-25T11:43:49Z

@jainvikas8 Please take a look at my review when you have the time.

lakshmih · 2022-05-10T01:55:42Z

[Qualcomm] We tested this and it passed on our 3.0 implementation. Will need more time for a detailed review.

bashbaug

This is a nice start but there are a few nice-to-have fixes and please check that the call to clSetKernelExecInfo is correct.

I also see there is a fair amount of code duplication between the SVM and SVM kernel exec info tests - have you considered any ways to reduce this code duplication?

Thanks!

-"}\n"

+const char* clone_kernel_test_kernel[] = {


Minor: consider using C++11 raw string literals here to make these tests easier to read and modify.

+                             cl_kernel* srcKernel, cl_int* value,
+                             cl_mem* bufOut)


Minor: I think we should pass the kernel, the value, and the buffer by value, rather than as a pointer.

bashbaug · 2022-05-17T05:18:21Z

test_conformance/api/test_clone_kernel.cpp

+    error = clSetKernelArgSVMPointer(*srcKernel, 1, pBuf);
+    test_error(error, "clSetKernelArgSVMPointer failed");
+    error = clSetKernelExecInfo(*srcKernel, CL_KERNEL_EXEC_INFO_SVM_PTRS,
+                                sizeof(pBuf), pBuf);
+    test_error(error, "clSetKernelExecInfo failed");


This doesn't quite look correct to me. pBuf is already set as an SVM pointer kernel argument, so it does not also need to be passed via clSetKernelExecInfo, but svmPtr_Kernel does. Can you please check that we shouldn't be passing svmPtr_Kernel to clSetKernelExecInfo instead of pBuf?

The call to clSetKernelExecInfo is not needed here, removed.

bashbaug · 2022-05-17T05:19:48Z

test_conformance/api/test_clone_kernel.cpp

+                             BufPtr* pBuf, cl_int* svmPtr_Kernel,
+                             cl_kernel* srcKernel, cl_int* value)


See above - I think we can pass most (if not all) of these by value.

Do we need to pass pBuf at all?

Minor: I'd also consider renaming this function to something like test_SVM_enqueue_helper, since this helper could work for other SVM tests and not just tests for clSetKernelExecInfo.

srcKernel and value are now passed by value.
pBuf removed as it was not used.
Function renamed to test_svm_enqueue_helper and the other helper removed.

+                            cl_int* value)


See above - do we need another helper here, or can we reuse the previous helper from clSetKernelExecInfo?
