help
|
|
This option controls verbose debugging information which can be
|
|
printed when the kernel detects an internal error. This debugging
|
|
information is useful to kernel hackers when tracking down problems,
|
|
but mostly meaningless to other people. It's safe to say Y unless
|
|
you are concerned with the code size or don't want to see these
|
|
messages.

Say Y here if you want to have an early console using the
|
|
earlyprintk=<name>[,<addr>][,<options>] kernel parameter. It
|
|
is assumed that the early console device has been initialised
|
|
by the boot loader prior to starting the Linux kernel.

config PID_IN_CONTEXTIDR

bool "Write the current PID to the CONTEXTIDR register"
|
|
help
|
|
Enabling this option causes the kernel to write the current PID to
|
|
the CONTEXTIDR register, at the expense of some additional
|
|
instructions during context switch. Say Y here only if you are
|
|
planning to use hardware trace tools with this kernel.
