I want to improve the performance of some game in our platform. I have heard of cache lock down feature to achieve performance improvement. Please suggest me how to use this feature in ARM Cortex-A7 for performance improvement.
The L1 and L2 Cache of Cortex-A7 don't support lockdown, you may consider other ways to improve performance. You can refer to the following links.
Re: L2 Cache difference between Cortex-A9 and Cortex-A7?
Does ARMv8 SOC support cache lockdown?
