172 | This special driver allows you to temporary use NMI debugger port | |

174 | ||
175 | Unlike KDB's disable_nmi command, with this driver you are always | |
176 | able to go back to the debugger using KGDB escape sequence ($3#33). | |
177 | This is because this console driver processes the input in NMI | |
178 | context, and thus is able to intercept the magic sequence. | |
179 | ||
180 | Note that since the console interprets input and uses polling | |
181 | communication methods, for things like PPP you still must fully | |
182 | detach debugger port from the KGDB NMI (i.e. disable_nmi), and | |
183 | use raw console. | |

863 | The pmac_zilog driver for the z85C30 chip on many powermacs | |
864 | historically used the device numbers for /dev/ttySn. The | |
865 | 8250 serial port driver also uses these numbers, which means | |
866 | the two drivers being unable to coexist; you could not use | |
867 | both z85C30 and 8250 type ports at the same time. | |
868 | ||
869 | If this option is not selected, the pmac_zilog driver will | |
870 | use the device numbers allocated for /dev/ttyPZn. This allows | |
871 | the pmac_zilog and 8250 drivers to co-exist, but may cause | |
872 | existing userspace setups to break. Programs that need to | |
873 | access the built-in serial ports on powermacs will need to | |
874 | be reconfigured to use /dev/ttyPZn instead of /dev/ttySn. | |
