Cache maintenance operations are defined to act on particular memory locations. In addition, for instruction caches and branch predictors, there are operations that invalidate all entries.
Consider using L1 Cache Functions and L2C-310 Cache Controller Functions for cache maintenance instead of raw register usage.
__STATIC_INLINE void __set_BPIALL | ( | uint32_t | value | ) |
[in] | value | BPIALL value to set |
This function writes the provided value to the Branch Predictor Invalidate All (BPIALL) register.
__STATIC_INLINE void __set_DCCIMVAC | ( | uint32_t | value | ) |
[in] | value | DCCIMVAC value to set |
This function cleans and invalidates data or unified cache line by MVA to PoC.
__STATIC_INLINE void __set_DCCMVAC | ( | uint32_t | value | ) |
[in] | value | DCCMVAC value to set |
This function cleans data or unified cache line by MVA to PoC.
__STATIC_INLINE void __set_DCIMVAC | ( | uint32_t | value | ) |
[in] | value | DCIMVAC value to set |
This function invalidates data or unified cache line by MVA to PoC.
__STATIC_INLINE void __set_ICIALLU | ( | uint32_t | value | ) |
[in] | value | ICIALLU value to set |
This function invalidates all instruction cache.
