Passing a length of CHIP_L1I_CACHE_SIZE() * or more invalidates the entire icache on all cores in the address * spaces. (Note: currently this option invalidates the entire icache * regardless of the requested address and length, but we may choose * to honor the arguments at some point.) * * Flush and invalidation of memory can normally be performed with the * __insn_flush() and __insn_finv() instructions from userspace. * The DCACHE option to the system call allows userspace * to flush the entire L1+L2 data cache from the core. In this case, * the address and length arguments are not used. The DCACHE flush is * restricted to the current core, not all cores in the address space. */ #define ICACHE (1<<0) /* invalidate L1 instruction cache */ #define DCACHE (1<<1) /* flush and invalidate data cache */ #define BCACHE (ICACHE|DCACHE) /* flush both caches */ #endif /* _ASM_TILE_CACHECTL_H */Overall Contributors
