Revert "tty: Set correct tty name in 'active' sysfs attribute"

2014-02-22T22:31:04Z

This reverts commit d8a5dc3033af2fd6d16030d2ee4fbd073460fe54. This breaks plymouth installs, either because plymouth is using the file "incorrectly" or because the patch is incorrect. Either way, this needs to be reverted until it is all figured out.

tty: Set correct tty name in 'active' sysfs attribute

2014-02-07T16:40:54Z

The 'active' sysfs attribute should refer to the currently active tty devices the console is running on, not the currently active console. The console structure doesn't refer to any device in sysfs, only the tty the console is running on has. So we need to print out the tty names in 'active', not the console names. This resolves an issue on s390 platforms in determining the correct console device to use.

tty: uartclk value from serial_core exposed to sysfs

2012-09-06T16:22:04Z

Added file /sys/devices/.../tty/ttySX/uartclk to allow reading uartclk value in struct uart_port in serial_core via sysfs. tty_register_device() has been generalized and refactored in order to add support for setting drvdata and attribute_group to the device.

tty: add 'active' sysfs attribute to tty0 and console device

2010-12-17T00:15:34Z

tty: add 'active' sysfs attribute to tty0 and console device Userspace can query the actual virtual console, and the configured console devices behind /dev/tt0 and /dev/console. The last entry in the list of devices is the active device, analog to the console= kernel command line option. The attribute supports poll(), which is raised when the virtual console is changed or /dev/console is reconfigured. Signed-off-by: Kay Sievers Signed-off-by: Greg Kroah-Hartman index 0000000..b138b66
