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

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