Send me your `lspci -vv`

Posted by snare on 8 June 2012. Tags: , ,

Got an Mac? I need your help. I want to find out a bit more about the hardware that’s in various Intel Macs – specifically about built-in PCI devices with onboard expansion ROMs. You can help me out by sending me the output of lspci -vv on your Mac. The only catch is you need to install a kernel extension to do it. But don’t worry, it’s software written by the CoreBoot dudes! They’re trustworthy, I swear!

EDIT2: I’ve had a couple of people having trouble building DirectHW. I’ve uploaded binaries here and here if you don’t want to build/have trouble building from source (and trust me).

The mission is dangerous, but if you’re ready, willing and able, this is what you need to do:

$ git clone http://review.coreboot.org/p/directhw.git
Cloning into 'directhw'...

remote: Counting objects: 59, done
remote: Finding sources: 100% (59/59)
remote: Total 59 (delta 16), reused 59 (delta 16)
Unpacking objects: 100% (59/59), done.

$ cd directhw/macosx
$ make pciutils
<snip>
created: /path/to/directhw/macosx/pciutils-3.1.7.dmg
Disk image done

$ make directhw
<snip>
created: /path/to/directhw/macosx/DirectHW/DirectHW.dmg
Disk image done

You’ll now have those two disk images created at the paths displayed at the end of the make processes. Install the packages in each of the DMGs, and then load the kernel extension:

$ sudo kextload /System/Library/Extensions/DirectHW.kext

EDIT: Oh I forgot, please turn off the energy saver setting (on laptops) to automatically switch graphics or whatever, so the non-integrated graphics card is powered on. You might need to log out and back in before it is powered on.

And get me the sweet, sweet lspci goodies:

$ sudo lspci -vv
00:00.0 Host bridge: Intel Corporation Device 0104 (rev 09)
	Subsystem: Apple Computer Inc. Device 00dc
	Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx-

	Latency: 0
	Capabilities: [e0] Vendor Specific Information: Len=0c <?>

Including the model and hardware specs of the machine would be great too:

$ system_profiler SPHardwareDataType|grep -v UUID|grep -v Serial

Email me the results at snare [at] this domain, or pastebin/gist it and tweet it at me. I appreciate all the help I can get, thanks very much!
