Dear POCL developers,
My name is Lee, Ki-Ju.
I'm working on porting OpenCL using POCL 0.7
I don't know whether you are the the person, who is related with my question.
If you are not the right person, I ask for understanding on my ignorance.
If you are the person, May I ask 3 questions related with deallocation of
objects, which are created in the POCL.
1. Cannot delete command queue object.
: is the POCL_RELEASE_OBJECT not required in clFinish after executing
clEnqueueNDRangeKernel function
, which calls clRetainCommandQueue?
2. Cannot delete program.devices, When I call clCreateProgramWithBianry
: when I use clCreateProgramWithBinary function to create program object
with offline compilation,
program.devices is different with context.devices.
if I use clCreateProgramWithSource, i don't need to consider for free of
that object.
Because the clReleaseContext makes free the context.devices.
But there is no deallocation for program.devices, when I call
clCreateProgramWithBinary.
3. Cannot delete mutex instance.
: in case of POCL_INIT_LOCK, some buffer could be allocated for creating
mutex(or semaphore) in some OS environment.
I think all the instances for mutex (or semaphore) should be deleted just
before deallocation of each object.
Here is an example -
#define POCL_FREE_LOCK(__LOCK__) mutex_free (&(__LOCK__))
#define POCL_FREE_OBJECT_NO_ICD(__OBJ__) \
do { \
POCL_FREE_LOCK ((__OBJ__)->pocl_lock); \
}
#define POCL_FREE_OBJECT(__OBJ__) \
POCL_FREE_OBJECT_NO_ICD(__OBJ__)
POname(clReleaseKernel)(cl_kernel kernel) CL_API_SUFFIX__VERSION_1_0
{
~~~~
POCL_FREE_OBJECT(kernel);
free(kernel);
}
If you give some answers or guidance, It should be very useful to me.
Thank you.
Regards,
Lee, Ki-Ju
