Questions About Mali Job Slot and Address Space

wlc

Hello there,

    I'am developing a job schedule policy for Mali T628. But I am confused about Jos Slot and Address Space:


1. What does Job Slot mean? What is the relationship between job slot and shader core?


     Mali T628 has 8 shader core. But I get the amount of  job slot is 3 ( by printk gpu_props->num_job_slots).


2. What does Address Space mean?

  

    Does it mean a space in memory to store process's context during context swicth?

     Is context switch by hardware?


3. What the GPU do during soft and hard stop a job?



Thank you!
