Mali T6xx kernel driver help

Hello there,

       I add a job schedule policy ( similar to mali_kbase_js_policy_cfs along with the driver  ) to the driver, and the new driver starts and init normally.

But it continually report following errors, and the graphic and opencl stack in user space can not run.

Error 1:

[   73.559188] [B0] Mali<ERROR, BASE_JM>: In file: drivers/gpu/arm/t6xx/kbase/src/common/mali_kbase_jm.c line: 172 function:kbase_jo

[   73.559200] [B0] t6xx: GPU fault 0x58 from job slot 0

I search in the driver, 0x58 means is "BASE_JD_EVENT_DATA_INVALID_FAULT".

Question 1:

What does BASE_JD_EVENT_DATA_INVALID_FAULT actually mean?

What should I do to solve the problem?

Error 2:

Question 2:

What does the error mean?

Which source code does the error come from?

What should I do to solve the problem?
