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

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
