test_api min_max_image_buffer_size

[rjodinchr]

In that test we are comparing CL_DEVICE_IMAGE_MAX_BUFFER_SIZE with CL_DEVICE_MAX_MEM_ALLOC_SIZE/MAX_DEVICE_MEMORY_SIZE_DIVISOR.

OpenCL-CTS/test_common/harness/deviceInfo.h

Line 53 in 5b35180

#define MAX_DEVICE_MEMORY_SIZE_DIVISOR (2)

/* We need to use a portion of available alloc size,
 * divide it to leave some memory for the platform. */

thus it means that if a device reports CL_DEVICE_IMAGE_MAX_BUFFER_SIZE = CL_DEVICE_MAX_MEM_ALLOC_SIZE/2 + 1, the test is failing, while it feels that it should still be passing.

leaving half of the space of the platform is quite a lot, and it feels quite arbitrary.

Am I missing something?
