Testing the I/O Control Interfaces

To test the ioctl commands, create additional ioctl entry points that are callable from a user application. Be sure to copy in the arguments appropriately. Use the ddi_copyin(9F) and ddi_copyout(9F) routines to transfer data to and from user address space. Then write an application to validate rendering, scrolling, and cursor behavior. This way, these ioctl commands do not affect your console while you develop and test the commands.

To ensure that the ioctl commands are working correctly, boot the system and log in. Check whether you get expected behavior when you execute commands such as prstat(1M), ls(1), vi(1), and man(1).

Execute the following script to validate that ANSI color is working correctly:

#!/bin/bash
printf "\n\n\n\e[37;40m             Color List       \e[m\n\n"
printf "\e[30m Color 30 black\e[m\n"
printf "\e[31m Color 31 red\e[m\n"
printf "\e[32m Color 32 green\e[m\n"
printf "\e[33m Color 33 yellow\e[m\n"
printf "\e[34m Color 34 blue\e[m\n"
printf "\e[35m Color 35 purple\e[m\n"
printf "\e[36m Color 36 cyan\e[m\n"
printf "\e[37m Color 37 white\e[m\n\n"
printf "\e[40m Backlight 40 black \e[m\n"
printf "\e[41m Backlight 41 red   \e[m\n"
printf "\e[34;42m Backlight 42 green \e[m\n"
printf "\e[43m Backlight 43 yellow\e[m\n"
printf "\e[37;44m Backlight 44 blue  \e[m\n"
printf "\e[45m Backlight 45 purple\e[m\n"
printf "\e[30;46m Backlight 46 cyan  \e[m\n"
printf "\e[30;47m Backlight 47 white \e[m\n\n"
