{bp-19229} arch/riscv: Add CONFIG_ARCH_RV_ISA_ZICSR_ZIFENCEI for fence.i#19291
Merged
Conversation
The fence.i instruction is only available when the Zifencei extension (CONFIG_ARCH_RV_ISA_ZICSR_ZIFENCEI) is supported by the hardware. This commit adds a macro wrapper around fence.i usages to prevent compilation errors on toolchains or targets where the Zifencei extension is absent.
