hi, experts:
In Cortex-A57 TRM chapter 4.3.66 :
It defines CPUACTLR_EL1 register, but this register name is not CPUACTLR_EL1.
Its name is S3_1_C15_C2_0.
Why?
best wishes,
hi
Sort of.
If you wrote "MSR CPUACTLR_EL1, x0" you would get an error, because it's an IMP DEF register and the tools don't recognize the name. Instead what you write is "MSR S3_1_C15_C2_0, x0".
Got it!
Thanks a lot!
