[RFC PATCH 04/22] clocksource: riscv: s64ilp32: Use __riscv_xlen instead of CONFIG_32BIT

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Guo Ren <guoren@xxxxxxxxxxxxxxxxx>

When s64ilp32 enabled, CONFIG_32BIT=y but __riscv_xlen=64. So we
must use __riscv_xlen to detect real machine XLEN for CSR access.
