Настройка ядра для работы с мультипортовой платой Advantech PCI-1620B

Сразу скажу, что настраивал работы только этой платы, про остальные ничего сказать не могу.

Изменение файла 8250_pci.c

1. Распаковываем выкаченное ядро в папку /usr/src
2. Для работы этой платы нужно изменить файл /usr/src/linux*/drivers/serial/8250_pci.c
Открываем этот файл ищем строку

#include "8250.h"

Далее добавляем

И сразу за ними вставляем

Конфигурирование ядра

Запускаем

make menuconfig

Идем в Device Drivers--->Character Devices ----> Serial Drivers
Устанавливаем

(20)  Maximum number of 8250/16550 serial ports
(20)  Number of 8250/16550 serial ports to register at runtime
[*]   Extended 8250/16550 serial driver options
[*]     Support more than 4 legacy serial ports
       <M>       Support Fourport cards
       <M>       Support Accent cards
       <M>       Support Boca cards
       <M>       Support Exar ST16C554/554D Quad UART
       <M>       Support Hub6 cards
[*]     Support for sharing serial interrupts

Далее делаем

make
sudo make modules_install
sudo make install
