tctrl
— Tadpole
Microcontroller Interface
tctrl0 at obio0
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
sparc/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
sparc/tslot(4).
