Macbook Pro 8,1 + Maverick

Hi bjaglin,

I m using the radeon drm module and it's work great with an external display : linux 3.4 efi boot.

i915 and radeon are compil as kernel module :
CONFIG_DRM_RADEON=m
CONFIG_DRM_RADEON_KMS=y
CONFIG_DRM_I915=m
CONFIG_DRM_I915_KMS=y

I've no more gmux patch, only lvds_dual_chanel, radeon load bios, and an intel enable/disable backlight : https://bugs.launchpad.net/ubuntu/+s...ux/+bug/954661

!!!!!!! Important !!!!!!!!!!!
copy vbios.bin in /lib/firmware/radeon/

My grub-efi entry for a radeon boot is like this :

menuentry ....
.......
search --no-floppy --fs-uuid --set=root xxxx
setpci -s 00:00.0 50.W=2
setpci -s 00:00.0 54.B=d
echo 'Loading kernel...'
linux /vmlinuz-3.4.0 root=UUID=xxxxxxx ro splash radeon.modeset=1 vt.handoff=7
initrd /initrd.img-3.4.0
}

Many thanks to wilfriedd for the set pci tips

Could you post those patches you're using? It's not obvious which ones I should grab.

Please could you also post your .config...My laptop monitor turns off shortly after boot and I have no way of debugging whats going on . I can only assume my .config is incorrect.

Cheers

Before applying the efifb high resolution patch, check your macbook pro's max resolution. If your MBP's max resolution is 1440x900, the patch will cause a corrupted screen for the radeon card. Not applying the patch will solve the problem.

I've got the high res Mbp 8,2 , and I have never applied this patch. The efifb always used the right high resolution even without the patch.

Thanks, radeon works finally on my laptop!

But I also needed the apple_bl patch for backlight control.

Which boot lines do you use when booting i915? I still use outb, but I don't know if it is still needed. Is setpci a replacement for that?

If you are with linux 3.4 you don't need this patch because there is a new module called apple_gmux in x86 drivers section :
CONFIG_APPLE_GMUX=m

Which boot lines do you use when booting i915? I still use outb, but I don't know if it is still needed. Is setpci a replacement for that?

Intel EFI boot :
...
outb 0x728 1
outb 0x710 2
outb 0x740 2
# Powers down radeon
outb 0x750 0
echo 'Loading kernel...'
linux /vmlinuz-3.4.0 root=UUID=xxxxxxxxxxxxx ro splash i915.lvds_channels=2 i915.modeset=1 i915.lvds_use_ssc=0 i915.i915_enable_rc6=1 vt.handoff=7
initrd /initrd.img-3.4.0

I've got the high res Mbp 8,2 , and I have never applied this patch. The efifb always used the right high resolution even without the patch.

Your are right, the efifb patch is useless because I don't use the efifb module now :
# CONFIG_FB_EFI is not set

Going to try this tomorrow, thanks!

I am trying out the 3.5rc2 vanilla kernel on MBP 8,2, and I'll round up the patches once I've got everything configured.

My question: I accidentally deleted my bios dumps (vbios.bin and int10.bin), could someone please post these files here?

I've swapped the cd drive for a ssd, and I don't think it's possible to boot into bios mode from an usb stick (is this correct?). Because of this i cannot make new dumps myself without swapping everything back.


Thanks so everyone who have contributed to this thread! Great work!

Here are mine. I have no idea if you can use them or not.
