name : Kconfig.erratas menu "CPU errata selection" config RISCV_ERRATA_ALTERNATIVE bool "RISC-V alternative scheme" default y help This Kconfig allows the kernel to automatically patch the errata required by the execution platform at run time. The code patching is performed once in the boot stages. It means that the overhead from this mechanism is just taken once. config CPU_SIFIVE bool "SiFive cores" help This enables support for SiFive CPU cores. Currently, It will enable all the SiFive errata Kconfig. Please say "Y" here if your platform uses SiFive CPU cores. Otherwise, please say "N" here to avoid unnecessary performance overhead. config ERRATA_SIFIVE_CIP_453 bool "Apply SiFive errata CIP-453" depends on CPU_SIFIVE depends on RISCV_ERRATA_ALTERNATIVE default y help This will apply the SiFive CIP-453 errata to add sign extension to the $badaddr when exception type is instruction page fault and instruction access fault. If you don't know what to do here, say "Y". endmenu
