NAME
       __riscv_flush_icache - Flush icaches on RISC-V

LIBRARY
       Standard C library (libc, -lc)

SYNOPSIS
       #include <sys/cachectl.h>

       int __riscv_flush_icache(void *start, void *end, unsigned long flags);

DESCRIPTION
       __riscv_flush_icache() enforces ordering between stores and instruction
       cache fetches.

       The range of addresses over which ordering is enforced is specified by
       start and end.

       The flags argument controls the extent of this ordering, with the
       default behavior (a flags value of 0) being to enforce the fence on all
       threads in the current process.  Setting the
       SYS_RISCV_FLUSH_ICACHE_LOCAL bit allows users to indicate that
       enforcing ordering on only the current thread is necessary.  All other
       flag bits are reserved.

STANDARDS
       Linux on RISC-V.

HISTORY
       Linux 4.15.  glibc 2.27.
