Re: [igt-dev] [PATCH i-g-t] lib/intel_batchbuffer: Media VME kernel is valid only for Gen11

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The kernel was design for Gen11 and the author didn't guarantee it could work on APL. And the binary was built with iga64 with "-p=11" option. If you try to build it with "-p=9" you will get "error: NoPreempt not supported on given platform". As the purpose of this test was to test the asymmetric subslice of Gen11, I would suggest to remove the support of Gen9 and Gen10. The patch looks good to me.

Regards,

Tony
