Request: Support for more serial ports in the default kernels.
by Andypoo from LinuxQuestions.org on (#6HJWX)
8250 serial driver supports more than 4 ports, and allows for a kernel parameter to request for more than the default number of ports, but there is a hard limit currently of 4 in Slackware's default kernels which means a kernel rebuild is required to go above 4.
Would it be possible to increase CONFIG_SERIAL_8250_NR_UARTS to 8 or even 16 in future kernels?
CONFIG_SERIAL_8250_RUNTIME_UARTS could stay as 4 (which limits the creation of additional ttys without a kernel parameter) to keep behaviour for the general public the same.
15.0/current:
Code:CONFIG_SERIAL_8250_NR_UARTS=4
CONFIG_SERIAL_8250_RUNTIME_UARTS=4Thanks (on behalf of all automation system and POS developers).
