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".
