OpenBSD on a MacBookPro8,2 using Intel GPU via Gmux and EFI

Some MacBooks have two graphics cards, the specific one this post is about is a MacBookPro8,2 (15-inch, Late2011) with an Intel HD Graphics 3000 and an AMD Radeon HD 6750M.

If you boot any OS into legacy BIOS mode (only option supported by – at this time – most recent release version 5.8 of OpenBSD), it is always the Radeon card that gets activated (except for Windows OS, where Bootcamp/drivers should handle the automatic switching just like in Mac OS).

You need an external USB WLAN card (or something else, if you want network access), because the internal one is not supported by OpenBSD.

After logging into the OpenBSD 5.8 installation via SSH (you have to do this, because on this computer OpenBSD 5.8 turns the display into a white screen after the kernel messages are through) and installing the Radeon firmware OpenBSD works on the machine, but it gets hot.

This seems to be caused by the Radeon GPU in use, unfortunately there is no way to disable it and enable the Intel card!

With the current version of OpenBSD (5.9) it is for the first time possible to boot via EFI.

I used an OpenBSD 5.9 snapshot from 26.01.2016 and refind to select the OS to boot on start up.

The GPT partition created to be used by OpenBSD 5.9 needs to be included in the hybrid MBR to be recognized by the OpenBSD EFI-booted installation (maybe there is a way to do this without using the hybrid MBR and just the GPT, but I couldn’t find it – this might even be a missing feature or bug). GPT fdisk is a nice utility to manipulate the (hybrid) MBR. It can be installed as EFI tool and started via refind.

After installation OpenBSD 5.9 still uses Radeon GPU (activated by default in EFI mode) and you cannot start X (because some data needed to be retrieved from BIOS by Radeon driver during boot is not found in EFI boot mode). But the Radeon shall not be used, anyway..

There are Linux distributions that work in EFI mode with activated Intel GPU on this computer (in fact, I have a parallel Debian installation running on my MacBook), but you need to configure your system to get Linux running, too.

With the help of the how-tos found about Linux & macbookpro8,2 plus some OpenBSD kernel hacking (see below) I found the following way to get OpenBSD 5.9 EFI installation using the Intel GPU on macbookpro8,2 (steps 1, 2 and 3 are source code modifications, 4 can be done by kernel configuration):

1. Added disabling of Radeon and enabling of Intel GPU to OpenBSD EFI boot loader.

CVS diff (see http://www.openbsd.org/anoncvs.html):

Don’t be scared by the black screen during OpenBSD boot. Just press enter after selecting OpenBSD EFI loader in refind menu (when the screen is already black) and wait, OpenBSD will appear after some seconds.

It is worth mentioning that a better option would be to let the OpenBSD kernel do this instead of the EFI boot loader. This way resume from standby might work, too. It does not work with this solution, because the Radeon GPU seems to automatically get reactivated during resume.. 😦

2. Replaced DDC EDID (GPU stuff..) probing function with a version I found in the Debian Linux kernel 3.16.7-ckt20 sources.

3. Set LVDS channel mode (more GPU stuff..) to “dual”.

< int i915_lvds_channel_mode __read_mostly;
---
> int i915_lvds_channel_mode __read_mostly = 2;

 

There seems to be no way to set this value during boot in OpenBSD as it is possible with Linux (e.g. via GRUB).

4. Disabled efifb0 device in compiled kernel (kernel includes results from step 2 and 3).

See http://www.openbsd.org/cgi-bin/man.cgi/OpenBSD-current/man8/config.8?query=config.

EFI framebuffer driver seems to interfere with the intel driver – without disabling it X won’t start (and there are other weird display problems on terminal). This might be just a bug that will get fixed in the future.

With these modifications OpenBSD 5.9 current/snapshot runs fine (X included) on macbookpro8,2 while using EFI & Intel GPU. 🙂
