Greentime Hu da29dbcda4 riscv: Add cache information in AUX vector ... There are no standard CSR registers to provide cache information, the way for RISC-V is to get this information from DT. sysconf syscall could use them to get information of cache through AUX vector. The result of 'getconf -a|grep -i cache' as follows: LEVEL1_ICACHE_SIZE 32768 LEVEL1_ICACHE_ASSOC 2 LEVEL1_ICACHE_LINESIZE 64 LEVEL1_DCACHE_SIZE 32768 LEVEL1_DCACHE_ASSOC 4 LEVEL1_DCACHE_LINESIZE 64 LEVEL2_CACHE_SIZE 524288 LEVEL2_CACHE_ASSOC 8 LEVEL2_CACHE_LINESIZE 64 LEVEL3_CACHE_SIZE 4194304 LEVEL3_CACHE_ASSOC 16 LEVEL3_CACHE_LINESIZE 64 LEVEL4_CACHE_SIZE 0 LEVEL4_CACHE_ASSOC 0 LEVEL4_CACHE_LINESIZE 0 Signed-off-by: Greentime Hu <greentime.hu@sifive.com> Signed-off-by: Zong Li <zong.li@sifive.com> Suggested-by: Zong Li <zong.li@sifive.com> Reviewed-by: Conor Dooley <conor.dooley@microchip.com> Link: https://lore.kernel.org/r/20220913061817.22564-8-zong.li@sifive.com Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>		2022-10-13 11:06:56 -07:00
