Your post is very well organized..

Thanks. I'll try to add to it as I go. The lack of a resource compiling things that are scattered across the net is pretty discouraging, and I hope to remedy it a little.

So far, I've seen no notable difference with issues other people have had — except for the lack of function keys for backlight control and the rest, but I am still to spend time debugging that.

I suggest you apply the b43 patches, that SHOULD solve the sd-card problem.....

Wow. That did the trick. Thanks a bunch, I really wouldn't have thought! the BCM4331 and the SD card reader share the same IRQ (17), and thus the card reader cannot work if b43 hasn't been loaded beforehand. I must admit I'm quite puzzled by this, but as long as I can unload b43 (blacklisting brings IRQ17 shutdowns again), I'll be ok.

Also, kernel-3.2 already have that b43 in-place, and the signal strength code in-place as well.... Try that... |
I tried 3.2rc3, but was unable to get a working intel display (so that's a major setback), although the LVDS dual channel patch did apply. Some people ran into the same issue on ubuntuforums, so it's not just me. Would anyone kernel-savvy and into the i915 driver around here have a clue about the why and how? |

Cool, thanks for the wonderful thread and also the dentifrice_'s blog.
I've applied the patch set to a 3.1.6 and everything is working but the screen back-lights.
The Keyboard backlight are working out of the box, just have to turn it on with the f5/f6 keys (note on a barebone GNOME 3.2 without any pommed or special settings installed).
There are even the on-screen things for the keyboard lights level. The other "fn" keys are perfect without any configuration (ok the launchpad and the mission control keys are not set...).
SD works out of the box.
Trackpad is too fast..but I've managed to have it acceptable tweaking xorg.conf
I didn't used rEFIT, but I just placed the grub.efi in a folder (in sda1) /EFI/boot/ named as BOOTX64.efi. This way I can boot directly in the grub menu:
at boot just keep pressed the Option key, until the boot menu appears. Select EFI boot and you will have the grub menu.
At the next boot the default will be boot on grub menu..to boot OSX you will have to press option and select OSX disk (it will change OSX back as default also)..and so on...
Only thing I have trouble on suspend my mac... The Bluetooth have serious issue to pair when the b43 modules is loaded (however my magic mouse sometime works sometime not...have to restart Bluetooth service manually or make some voodoo rite...).
I can't wait when I will have both radeon and intel working in the same kernel and able to switch.
I have a 3.2 rc6 with radeon to test Bluetooth/wifi coexistence but nothing changes. otherwise I use Intel (on 3.1.*)
good work!
my cflags:
CFLAGS="-O2 -march=corei7-avx -mtune=corei7-avx -pipe"
ps this laptop with gentoo (ops I have funtoo..however) is a sources eater... compiled webkit-gtk in 15 min vs core2-duo 2.4Ghz 1h and more.. yes I also have 8 cpu here!!!
I can even boot my old HD with my old macbook linux system via USB. (I put the old HD in a USB disk case). This might be useful for those that want to skip the partitionig of the main HD...using an external drive or a big USB stick.

Read recent updates from the very long thread:
http://ubuntuforums.org/showthread.php?t=1695746&page=80
I'm glad to say running vanilla-sources-3.2.1 fixes most of the needs for a mbp 8,2 machine.
So, I like to sum up the steps so anyone who own these machines enjoys running open sources software with power!
1. apply the i915 reverse patch to enable i915_lvds_channels works:
| Quote: | | https://github.com/fooblahblah/linux-mainline-efi-lvds/blob/master/i915_reverse.patch |
2. apply those patches for apple_bl, apple_gmux, radeon_bioe as usual, to simply patching work, you may download those patches: | Quote: | | www.eternalit.com/~alvin/download/3.2 |
OK, now it's time to make that workable as my best tool.
1. Compile those radeon, i915 drivers as modules
2. Use the kernel command parameter as a reference point
3. Modify grub.cfg, reference to the 3.2.1 modules, blacklist either modules that you don't want

4. Create a igd-gpu program that switches the apple gpu gmux, contribute by:
| Quote: | | http://ubuntuforums.org/showthread.php?t=1695746&page=27 |
5. Create some local scripts (my setup in /usr/local/sbin)
local-xorg -> to modify contents inside /etc/X11/xorg.d/ to tailor the behavior of xorg server pulling drivers, according to the kernel command line parameter
| Quote: |
#!/bin/bash
#set -x
r_x_f="/etc/X11/xorg.conf.d/01-radeon-mbp82.conf"
cmdline=`dmesg|head|grep "Command line:"`
mpbl=`echo "$cmdline" | sed -e 's@^.*modprobe.blacklist=@@'`
# exit when no modprobe.blacklist for radeon or i915 in the kernel command line
[[ "$cmdline" == "$mpbl" ]] && exit
if [[ -n `echo $mpbl | grep i915` ]] ; then
cat <<EOF> $r_x_f
Section "Device"
Identifier "Card0"
Driver "radeon"
BusID "1:0:0"
Option "ColorTiling" "1"
Option "ForceLowPowerMode" "1"
EndSection
EOF
#wait
fi
if [[ -n `echo $mpbl | grep radeon` ]] ; then
[[ -f $r_x_f ]] && rm $r_x_f
/usr/local/sbin/igd-gpu
fi
exit
|
| Quote: |
#!/bin/bash

6. Create systemd.service units to control the operations
| Quote: |

7. It is very experimental, fine tunes are welcome
8, Suspend, resume under radeon is ok but not under i915
9. Most of the functions are working fine
Hope you enjoy, while under i915 environment, the machines works ~7 hours!
So, with a simple reboot, you can select external monitor support via radeon, or long battery life via i915.
Great works from ubuntu, gmae, archlinx,fedora, freedesktop,....experts!
BTW: suspend/resume under radeon working fine but not under i915 |

Since I encounter occasional kernel panic while bootup with i915, I change a little bit about the setup to make it easier (not 100%) to boot successfully:
Add i915 (together with radeon) to the blacklist kernel command line if you want to boot with it:
| Quote: |
linux /boot/kernel-genkernel-x86_64-3.2.1 root=UUID=b3be74a4-938d-4a62-a062-952626e84212 ro quiet add_efi_memmap modprobe.blacklist=i915,radeon real_init=/bin/systemd |
Modify the service parm as:
| Quote: |
[Unit]
Description=Local custom xorg conf base on kernel boot parm for radeon or i915 driver
Requires=basic.target
After=basic.target
Before=default.target
[Service]
Type=oneshot

[Install]
WantedBy=multi-user.target |
Replace /usr/local/sbin/local-xorg by the following script:
| Quote: |
#!/bin/bash
#set -x
r_x_f="/etc/X11/xorg.conf.d/01-radeon-mbp82.conf"
cmdline=`dmesg|head|grep "Command line:"`
mpbl=`echo "$cmdline" | sed -e 's@^.*modprobe.blacklist=@@'`
# exit when no modprobe.blacklist for radeon or i915 in the kernel command line
[[ "$cmdline" == "$mpbl" ]] && exit
mpbl=`echo "$mpbl" | sed -e 's@[ \t].*$@@'`
if [[ "$mpbl" =~ 'radeon' ]] && [[ "$mpbl" =~ 'i915' ]] ; then
[[ -f $r_x_f ]] && rm $r_x_f
/usr/local/sbin/igd-gpu
modprobe i915
exit
else
if [[ "$mpbl" =~ 'i915' ]] ; then
cat <<EOF> $r_x_f

I change the service parm as below to make it more reliable:
| Quote: |
[Unit]
Description=Local custom xorg conf base on kernel boot parm for radeon or i915 driver
Requires=basic.target
After=basic.target
After=multi-user.target

Upon recent update to systemd-43, I had to modify the custom unit file as below:
| Code: |
[Unit]
Description=Local custom xorg conf base on kernel boot parm for radeon or i915 driver
Before=graphical.target
[Service]
Type=oneshot
ExecStart=/usr/local/sbin/local-xorg
[Install]
WantedBy=multi-user.target
|
And I found previous script was a bit messy, I re-post:
| Code: |
#!/bin/bash
#set -x
r_x_f="/etc/X11/xorg.conf.d/01-radeon-mbp82.conf"
cmdline=`dmesg|head|grep "Command line:"`
mpbl=`echo "$cmdline" | sed -e 's@^.*modprobe.blacklist=@@'`
# exit when no modprobe.blacklist for radeon or i915 in the kernel command line
[[ "$cmdline" == "$mpbl" ]] && exit
mpbl=`echo "$mpbl" | sed -e 's@[ \t].*$@@'`
if [[ "$mpbl" =~ 'radeon' ]] && [[ "$mpbl" =~ 'i915' ]] ; then
[[ -f $r_x_f ]] && rm $r_x_f
/usr/local/sbin/igd-gpu
# modprbe apple_bl
modprobe i915
exit
else
if [[ "$mpbl" =~ 'i915' ]] ; then
[[ -f "$r_x_f" ]] && exit
cat <<EOF> $r_x_f

Identifier "Card0"
Driver "radeon"

EndSection
EOF
exit
else
if [[ "$mpbl" =~ 'radeon' ]] ; then
[[ -f $r_x_f ]] && rm $r_x_f
