# we want to change this to something like CONFIG_SYSCTRL_CUDA/PMU
config ADB_CUDA
bool "Support for CUDA based PowerMacs"
depends on PPC_PMAC
help
This provides support for CUDA based Power Macintosh systems. This
includes most OldWorld PowerMacs, the first generation iMacs, the
Blue&White G3 and the "Yikes" G4 (PCI Graphics). All later models
should use CONFIG_ADB_PMU instead. It is safe to say Y here even if
your machine doesn't have a CUDA.
If unsure say Y.
config ADB_PMU
bool "Support for PMU based PowerMacs"
depends on PPC_PMAC
help
On PowerBooks, iBooks, and recent iMacs and Power Macintoshes, the
PMU is an embedded microprocessor whose primary function is to
control system power, and battery charging on the portable models.
The PMU also controls the ADB (Apple Desktop Bus) which connects to
the keyboard and mouse on some machines, as well as the non-volatile
RAM and the RTC (real time clock) chip. Say Y to enable support for
this device; you should do so if your machine is one of those
mentioned above.
config PMAC_PBOOK
bool "Power management support for PowerBooks"
depends on ADB_PMU
---help---
This provides support for putting a PowerBook to sleep; it also
enables media bay support. Power management works on the
PB2400/3400/3500, Wallstreet, Lombard, and Bronze PowerBook G3 and
the Titanium Powerbook G4, as well as the iBooks. You should get
the power management daemon, pmud, to make it work and you must have
the /dev/pmu device (see the pmud README).
Get pmud from <ftp://ftp.samba.org/pub/ppclinux/pmud/>.
If you have a PowerBook, you should say Y here.
You may also want to compile the dma sound driver as a module and
have it autoloaded. The act of removing the module shuts down the
sound hardware for more power savings.
config PM
bool
depends on PPC_PMAC && ADB_PMU && PMAC_PBOOK
default y
config PMAC_APM_EMU
tristate "APM emulation"
depends on PMAC_PBOOK
# made a separate option since backlight may end up beeing used
# on non-powerbook machines (but only on PMU based ones AFAIK)
config PMAC_BACKLIGHT
bool "Backlight control for LCD screens"
depends on ADB_PMU
help
Say Y here to build in code to manage the LCD backlight on a
Macintosh PowerBook. With this code, the backlight will be turned
on and off appropriately on power-management and lid-open/lid-closed
events; also, the PowerBook button device will be enabled so you can
change the screen brightness.
config MAC_FLOPPY
bool "Support for PowerMac floppy"
depends on PPC_PMAC
help
If you have a SWIM-3 (Super Woz Integrated Machine 3; from Apple)
floppy controller, say Y here. Most commonly found in PowerMacs.
config MAC_SERIAL
tristate "Support for PowerMac serial ports (OBSOLETE DRIVER)"
depends on PPC_PMAC
help
This driver is obsolete. Use CONFIG_SERIAL_PMACZILOG in
"Character devices --> Serial drivers --> PowerMac z85c30" option.
config ADB
bool "Apple Desktop Bus (ADB) support"
depends on PPC_PMAC
help
Apple Desktop Bus (ADB) support is for support of devices which
are connected to an ADB port. ADB devices tend to have 4 pins.
If you have an Apple Macintosh prior to the iMac, an iBook or
PowerBook, or a "Blue and White G3", you probably want to say Y
here. Otherwise say N.
config ADB_MACIO
bool "Include MacIO (CHRP) ADB driver"
depends on ADB
help
Say Y here to include direct support for the ADB controller in the
Hydra chip used on PowerPC Macintoshes of the CHRP type. (The Hydra
also includes a MESH II SCSI controller, DBDMA controller, VIA chip,
OpenPIC controller and two RS422/Geoports.)
config INPUT_ADBHID
bool "Support for ADB input devices (keyboard, mice, ...)"
depends on ADB && INPUT=y
help
Say Y here if you want to have ADB (Apple Desktop Bus) HID devices
such as keyboards, mice, joysticks, trackpads or graphic tablets
handled by the input layer. If you say Y here, make sure to say Y to
the corresponding drivers "Keyboard support" (CONFIG_INPUT_KEYBDEV),
"Mouse Support" (CONFIG_INPUT_MOUSEDEV) and "Event interface
support" (CONFIG_INPUT_EVDEV) as well.
If unsure, say Y.
config MAC_EMUMOUSEBTN
bool "Support for mouse button 2+3 emulation"
depends on INPUT_ADBHID
help
This provides generic support for emulating the 2nd and 3rd mouse
button with keypresses. If you say Y here, the emulation is still
disabled by default. The emulation is controlled by these sysctl
entries:
/proc/sys/dev/mac_hid/mouse_button_emulation
/proc/sys/dev/mac_hid/mouse_button2_keycode
/proc/sys/dev/mac_hid/mouse_button3_keycode
If you have an Apple machine with a 1-button mouse, say Y here.
