[edit] CPU

[edit] Support for VT

As of Mac Pro EFI Firmware Update 1.1, the processors are VMX-capable. The update can be downloaded from Apple's website, or by Software Update.

[edit] Support for Multiple CPUs/Cores

A recommended kernel configuration is below. If you've upgraded your Mac Pro to dual quad-core processors, then change "4" to "8" below.

Hyper-Threading is in cold storage for the time being (says Intel), so be sure to disable SMT support.

Processor type and features  --->
 Processor family (Intel EM64T)
  <*> /dev/cpu/*/msr - Model-specific register support
  <*> /dev/cpu/*/cpuid - CPU information support
  [*] MTRR (Memory Type Range Register) support
  [*] Symmetric multi-processing support
  [ ]   SMT (Hyperthreading) scheduler support
  [*]   Multi-core scheduler support
  Preemption Model (No Forced Preemption (Server))
  (4) Maximum number of CPUs (2-256)
  [*] Provide RTC interrupt
  [*] Machine check support
  [*]   Intel MCE features
  [*] Function reordering

For optimal performance, you may want to add "threads" to your USE flags to enable multithreading in packages that support it.

[edit] Support for SSE

The processors fully support MMX, SEE, SSE2, SSE3, and SSSE3. At this time, though, GCC does not support SSSE3.

[edit] Support for 64-bit

The Mac Pro has full EM64T support in Gentoo, when using the AMD64 profiles. (x86 profiles are only 32-bit). The CPU's automatically go into long mode when the kernel is loaded.

[edit] Memory

[edit] Support for Large Amounts of Memory

The 64-bit kernel has high memory support built-in. There are no kernel options to configure.

On 32-bit systems, you will need to configure high memory support.

Processor type and features  --->
 High Memory Support  --->
  ( ) None
  (X) 4GB
  ( ) 64GB

• Select "None" if you have 896 MB of memory or less. (PROTIP: No Mac Pro has this configuration.)
• Select 4GB if you have between 1 and 4 gigabytes of RAM.
• Select 64 GB if you have more than 4 GB of RAM. Otherwise you will only see 2GB. (This is for MacPro boxes ONLY!)

In order to enable the NX bit, this must be set to 64 GB.

[edit] Input Devices

[edit] Use the apple drivers

It could be that udev loads usbhid before appleir and appletouch and the apple drivers cannot bnd to the devices any more. To circumvent this problem you should add the following to your /etc/conf.d/local.start:

rmmod usbhid appletouch appleir
modprobe appleir
modprobe appletouch
modprobe usbhid pb_fnmode=2

you can look in modinfo to see what pb_fnmode does:

# modinfo -p usbhid
mousepoll:Polling interval of mice
pb_fnmode:Mode of fn key on PowerBooks (0 = disabled, 1 = fkeyslast, 2 = fkeysfirst)

I for one like to have them first for kde's ALT+F2 = "Run command"

[edit] Ethernet

The MacPro uses the e1000 driver for the machines two ethernet jacks (eth0 and eth1).

EDIT:
The Core2Duo MBP uses the sky2 driver. This driver is listed as experimental in the 2.6.22 kernel but it appears to work fine for me.

[edit] Sound

Sound now works with alsa-driver-0.14-r3 with intel-hda

[edit] Wifi

See the MadWifi article.

[edit] Bluetooth

To enable bluetooth edit /etc/conf.d/bluetooth for hid2hci: Just change HID2HCI_ENABLE=false to true and make sure that bluetooth is started at boot with rc-update show.

[edit] DVD/CD burning

The cdrom does not work with the "classical" IDE drivers. However as of 2.6.19-rc1 the libata PATA drivers are in the mainline kernel and if you enable this new libata based IDE driver (CONFIG_PATA_MPIIX) and also activate SCSI CDROM support (CONFIG_BLK_DEV_SR) you will be able to use your CD drive as /dev/sr0.

This is complete nonsense. WHY??

[edit] Power Management

[edit] Frequency Scaling

Works perfectly using speedstep_centrino (using kernel 2.6.16 and 2.6.17).

I have not yet gotten CDROM or Muteing working but I cannot see the problem with the config. Start the daemon:

/etc/init.d/pbbuttonsd start

as user:

gtkpbbuttons -t MacOSX

[edit] Remote Control

[edit] Assigning key values to remote control buttons through xmodmap

The Apple remote control (RC) can work without Lirc; it works out of the box as an extension to the keyboard, and can easily be assigned key values through xmodmap, which is a command that comes with Xorg. Running the command xev, you can find out each RC key keycode; after that, you can bind those keys to keyboard keys. For example, I've created ~/.xmodmap with

keycode 153 = Right
keycode 144 = Left
keycode 176 = 0
keycode 174 = 9
keycode 162 = space
keycode 158 = v

so I can control mplayer with it ;-)

After creating the file, you should run

xmodmap ~/.xmodmap

and don't forget to run it each time you run Xorg. You can also do it automagically.

[edit] Using the volume and remote control events in applications with inputlircd

emerge -va inputlircd
USE=lirc emerge -va mplayer
/etc/init.d/inputlircd start

You may want to use the irexec daemon additionally to manage the volume level independant of the media application. To do so you'll want to edit the /etc/lircrc file as below, run "irexec --daemon", and then start mplayer.

#

begin
        prog = mplayer
        button = KEY_PLAYPAUSE
        config = pause
end

begin
        prog = mplayer
        button = KEY_PREVIOUSSONG
        config = seek -10
        repeat = 1
end

begin
        prog = mplayer
        button = KEY_NEXTSONG
        config = seek +10
        repeat = 1
end

#begin
#       prog = mplayer
#       button = KEY_VOLUMEUP
#       config = volume 1
#       repeat = 1
#end

#begin
#       prog = mplayer
#       button = KEY_VOLUMEDOWN
#       config = volume -1
#       repeat = 1
#end

begin
prog = irexec
button = KEY_VOLUMEUP
config = amixer set PCM 3%+ &
repeat = 2
end
begin
prog = irexec
button = KEY_VOLUMEDOWN
config = amixer set PCM 3%- &
repeat = 2
end

[edit] Apple Keyboard layout - use with Xmodmap

The keyboard is supported by USB-HID. but there seem to be no good keymaps for it.

One possible solution (for an X environment) is to use a xmodmap, my first try looks like this:

!!
!! xmodmap for Apple MacBook - German layout 
!!
! Let the left apple key act as mode switch
keycode 115 = Mode_switch
! Use the right apple switch as "ALT_GR" key, provides the additional
! characters you find on a tradition pc keyboard (example @)
! !! Also this key acts as right mouse button when used with left apple key
keycode 116 = ISO_Level3_Shift NoSymbol Pointer_Button3
! Use the Delete key correctly
! Maps to center mouse if used with left apple key
keycode 108 = Delete Delete Pointer_Button2
! Page Up/Down 
keycode 98 = 0xff52 NoSymbol 0xff55
keycode 104 = 0xff54 NoSymbol 0xff56
keycode 100 = 0xff51 NoSymbol 0xff50
keycode 102 = 0xff53 NoSymbol 0xff57
! Switch keys ( lt/gt <-> circle/accent )
keycode 94 = 0xfe52 0x00b0 0x00ac 0x00ac 0x00ac 0x00ac
keycode 49 = 0x003c 0x003e 0x007c 0x00a6 0x007c 0x00a6

This .xmodmap file is for the german keyboard layout, the last two lines will propably not apply to other versions. To make the keyboard -> Mouse click mappings work you will need to install a small tool (i could not find in in portage), get it here. When installed run at the beggining of each X-session:

xmodmap <the_file_above>
xkbset exp m
xkbset m

Please note that this key-mapping will not make the keyboard work as printed on the keys, but will match a standard german keyboard. Hints for your own tries: xev (event debugger - lets you see what keycodes are sent), xmodmap and its man-page.

[edit] Map F11 and F12 to mouse button 2 and 3

Linux doesn't support Ctrl-clicking like Mac OS X does. To use keys for the missing second and third mouse button you need to enable CONFIG_MAC_EMUMOUSEBTN in the kernel, you need the patch to show it on x86 and do the following:

echo 1 > /proc/sys/dev/mac_hid/mouse_button_emulation
echo 87 > /proc/sys/dev/mac_hid/mouse_button2_keycode #for F11
echo 88 > /proc/sys/dev/mac_hid/mouse_button3_keycode #for F12

References to the nvidia and ati wiki pages to setup X11 should be placed here

[edit] Xen

[edit] XGL

XGL works out perfectly on MacPro. Rain effects run smoothely. I suggest you use the Gentoo-based distro Sabayon to get a quick start on making machine to use XGL.

[edit] Mac Inspired Themes

information on mac-like gtk engines and themes should go here

[edit] Accessing OSX HFS+ Filesystem

Full article: HOWTO hfsplus

To read, write, and mount HFS+ partitions in Gentoo, enable GPT partition table support and Mac filesystem support in your kernel, and then emerge sys-fs/hfsplusutils.

It is highly recommended that any Mac filesystems that you mount in Gentoo have journaling disabled.

As an alternative, you can install ExtFSManager in Mac OS X, which will let you mount ext2 and ext3 volumes.

[edit] Audio

MacPro can play basic audio through the Alsa snd-hda-intel driver. Unfortunately, there is a bug in this driver that will play sound, but the sound will be VERY VERY quiet. I have to crank up my stereo just to give anything. Sound does not simultaneously output to the internal speakers. I'm not sure if its even possible as an output.
