The corresponding hardware issues of CONFIG_ERRATA_SIFIVE_CIP_453 and CONFIG_ERRATA_SIFIVE_CIP_1200 only exist in the SiFive 64bit CPU cores. Therefore, these two errata are required only if CONFIG_64BIT=y Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Vincent Chen <vincent.chen@sifive.com> Fixes:bff3ff5254("riscv: sifive: Apply errata "cip-1200" patch") Fixes:800149a77c("riscv: sifive: Apply errata "cip-453" patch") Signed-off-by: Palmer Dabbelt <palmerdabbelt@google.com>

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.

All SiFive errata Kconfig depend on this Kconfig. Disabling
|
|
this Kconfig will disable all SiFive errata. Please say "Y"
|
|
here if your platform uses SiFive CPU cores.
|
|
|
|
Otherwise, please say "N" here to avoid unnecessary overhead.

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".

This will apply the SiFive CIP-1200 errata to repalce all
