10 bool "Early printk support"
13 Say Y here if you want to have an early console using the
14 earlyprintk=<name>[,<addr>][,<options>] kernel parameter. It
15 is assumed that the early console device has been initialised
16 by the boot loader prior to starting the Linux kernel.
18 config PID_IN_CONTEXTIDR
19 bool "Write the current PID to the CONTEXTIDR register"
21 Enabling this option causes the kernel to write the current PID to
22 the CONTEXTIDR register, at the expense of some additional
23 instructions during context switch. Say Y here only if you are
24 planning to use hardware trace tools with this kernel.
