DESCRIPTION
The
tctrl driver provides control over many functions on the Tadpole SPARCbook 3 series laptops, via their TS102 chip. The microcontroller is used to power the TFT display down when the laptop lid is closed and when the screen is blanked by the
pnozz(4) driver. The
tctrl is also used to power the laptop off when the
reboot(2) system call is used with the
RB_POWERDOWN flag is set. Power button events are forwarded to
powerd(8). The PCMCIA part of the controller is supported by
tslot(4).
