CONFIG_UNIX98_PTY_COUNT: Maximum number of Unix98 PTYs in use (0-2048)

General informations

The Linux kernel configuration item CONFIG_UNIX98_PTY_COUNT has multiple definitions:

Maximum number of Unix98 PTYs in use (0-2048) found in arch/h8300/Kconfig

The configuration item CONFIG_UNIX98_PTY_COUNT:

Help text

The maximum number of Unix98 PTYs that can be used at any one time. The default is 256, and should be enough for desktop systems. Server machines which support incoming telnet/rlogin/ssh connections and/or serve several X terminals may want to increase this: every incoming connection and every xterm uses up one PTY.

When not in use, each additional set of 256 PTYs occupy approximately 8 KB of kernel memory on 32-bit architectures.
