linux.git/arch/csky/include/asm/cacheflush.h, branch v5.6 Linux kernel source tree csky: Add flush_icache_mm to defer flush icache all 2020-02-21T07:43:24+00:00 Guo Ren guoren@linux.alibaba.com 2020-01-31T12:33:10+00:00 997153b9a75c08d545ad45e6f8ceb432435d2425 Some CPUs don't support icache.va instruction to maintain the whole smp cores' icache. Using icache.all + IPI casue a lot on performace and using defer mechanism could reduce the number of calling icache _flush_all functions. Signed-off-by: Guo Ren <guoren@linux.alibaba.com>
