opencl and opengles Interop problem

Is there exsiting default timeout value if the openCL kernel is complex that set by gpu to prevent the kernel from locking up the gpu ,such as compute time is more than 25 ms on gpu.

Thx.

Two levels of timeout can be set in the kernel driver, and are configured by the system integrator:

• SOFT_STOP - jobs taking longer than this are suspended to allow other things to run, but can be restarted later
• HARD_STOP - jobs which take longer than this and which don't SOFT_STOP are killed

However in general these are relatively high timeouts designed for system stability, not for interactive scheduling of work within a process. If the foreground application is sending very large workloads to the GPU then it probably has a good reason to do so, and it really isn't the job of the GPU driver to second guess what the application developer told us to do. Even for graphics-only applications there is content which runs slower than 30 FPS especially at high resolutions - we've certainly seen some benchmarks submit single rendering operations which take longer than 200ms - and it would be "wrong" to kill those workloads.
