When I boot in any linux (Ubuntu, OpenSUSE, Debian) laptop's keyboard and mouse don't work at all. Still I am able to use external mouse and keyboard.
Hi Folks. To give you something to work with, I have installed Ubuntu 15.10 Beta and updated to 4.2 Kernel.Still the same behavor no Keyboard, no trackpad and no harddisk :( I have attached some logfiles.

Hi Guys on openSUSE I found this info: "I tried a similar thing last weekend. Like you I've experimented with Ubuntu, so I'm afraid I detailed the results in an Ubuntu Forum so a not to mix things up. http://ubuntuforums.org/showthread.php?t=2290700 Essentially it's because the keyboard is attached via the SPI interface, rather than USB - if you notice the Macbook Pro & Air users are lucky enough to see the keyboard/touchpad in the list when they type lspci. We are not so lucky. We see the SPI interface when you type lspci, but I've not found any information on how to list the devices hanging off the SPI bus (it doesn't appear in /sys/bus/spi)." https://forums.opensuse.org/showthread.php/507933-openSUSE-on-the-2015-Apple-12-Inch-Retina-MacBook/page3 Perhaps it helps. derarnold
I think the reason the MacBook NVMe SSD isn't being found is Apple messed up and gave it the wrong PCI Class ID: drivers/block/nvme-core.c: "#define PCI_CLASS_STORAGE_EXPRESS 0x010802" Apple: "pci 0000:03:00.0: [106b:2001] type 00 class 0x018002" PCI Class 01 == Mass Storage, 08 == Non-Volatile memory controller, 02 == NVM Express
Clarification: "messed up" == the controller device isn't really NVMe.

Hello all. It took a while, but I have the logfiles. To help you guys to create a bootable stick to debug yourself, here is a guide that finally worked: http://www.lug-stormarn.de/index.php/infos/13-linux-auf-dem-macbook-air It is in German, but if you see the commands, you will understand. In this ticket, we track the keyboard & trackpad issue. I will create a new ticket for the NVM. You can find it here: https://bugzilla.kernel.org/show_bug.cgi?id=105621 So now to our problem: When booting, the driver i2c-801 is not loaded. After manually loading, the keyboard & mouse is still not working :( I attached some more logfiles for you. Oliver P.s. since I have a working boot usb stick now, i can provide logs & tests much faster.
Apple's NVMe controller should be supported from now on: http://lists.infradead.org/pipermail/linux-nvme/2015-November/002975.html I'm working on the SPI keyboard, but so far... it's digging around. What I found: There is an Intel-based serial controller (8086 9ce6) |-> Below that one there is an 8086 049c (or is it 9c04--that crappy XML ouput given by OSX is one of the reasons I refuse to use it any more...), which is reported to be a SATA controller (wtf?) |-> below that one there are chained AppleIntelLpssSpiController and AppleIntelLpssSpiDevice |-> there is finally an AppleHSSPIController that connects the Apple Internal Keyboard / Trackpad That info comes from OSX on an MacBook8,1. With Linux I see the Intel SPI controllers but any driver refuses to claim them. Manual binding worked with the intel-pxa* modules, generating spi nodes in /sys/class/bus/spi/devices. However, I don't had any luck to expose the bcm5974 that is supposed to sit there nor the keyboard/trackpad. So far, my Filco is my best friend.
Can anyone confirm that this patch is in the Linux 4.3 release?
(In reply to derarnold from comment #16) > Can anyone confirm that this patch is in the Linux 4.3 release? Have a look at the sources and answer the question yourself. It has never been meant to be part of 4.3, it was only tested against a late RC. With any luck it may be part von 4.4. But beware that there are reports of sudden controller resets and data loss.
Hi. I just saw the following CL in the kernel git. It looks like it could bring the trackpad to life. https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id=22f8e9dbf671a2f36d90d3d8723a2a0c5227fa4b Can anyone confirm, they work? Oliver

Hi, are there any updates on the progress on keyboard/trackpad support?
On this post: http://www.spinics.net/lists/linux-acpi/msg61848.html This guy is saying that on both the Macbook8,1 12-inch and the MacbookPro 13-inch, OSX reports the keyboard/trackpad as being connected via SPI --not USB. However, with Linux the keyboard/trackpad show up as USB devices on the MacbookPro12,1, but remain hidden for the Macbook8,1. Just a thought, but maybe the keyboard/trackpad should also be showing up as USB devices on the Mackbook8,1 as well in Linux.
(In reply to leif from comment #23) > Just a thought, but maybe the keyboard/trackpad should also be showing up as > USB devices on the Mackbook8,1 as well in Linux. Can you clarify what you mean? Are you saying that it's possible that Mac OS X sees it as a USB device and not SPI? As moepi says above, Mac OS X reports it as SPI. I'm running Mac OS X and running system_profiler lists it as an SPI device as well.

The keyboard works in grub, and grub is using some pretty generic drivers. If anyone has ANY ideas of what to look for, things to test for, or what data to gather and post --please let me know. I've just posted the output of lshw. I'm running Fedora 23, 4.4.0-0.rc8 kernel, and have no external devices connected.

Has anyone tested the status on the released kernel 4.4?
Tried it today, nothing has changed. If the issue is due to the spi_pxa2xx_platform driver not binding to the spi controller , than our best hope lies in the linux-next repo. There's a handful of pxa2xx-related commit's queued up to be merged into kernel 4.5.
Has anyone got bluetooth working? Normally on macbooks, the device is discovered by usb and shows up as a "Bluetooth USB Host Controller"
This device looks like a bluetooth serial port??? --but there no modalias listed for BCM2E7C. P: /devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/device:17/BCM2E7C:00 E: DEVPATH=/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/device:17/BCM2E7C:00 E: ID_VENDOR_FROM_DATABASE=Broadcom E: MODALIAS=acpi:BCM2E7C:APPLE-UART-BLTH: E: SUBSYSTEM=acpi E: USEC_INITIALIZED=7539067
So, if it's (trackpad) USB then it has nothing to do with LPSS. If it's one of LPSS connected device then close this bug with duplication to bug #110901.
I have no knowledge of these things, but I read through this[0] (moepi's email to the acpi list) again and decided to google the hwid mentioned, "APPLE-SPI-TOPCASE" and I found this[1], some random fellow who seems to have put DSDT info on github, and apparently, the MacBookAir6,2 has this device listed as SPIT. It has the similar (or same) ACPI ID[2], APP000D. Looking up things, I don't see any issues with that machine's keyboard, although the keyboard might not be connected via SPI. Unfortunately, for the little googling I'm capable of doing tonight[3], I don't know of driver information for SPI devices on that machine. But it's a step forward, at least this device exists on another machine that has full linux support.

I should clarify that per [3] on that last post that the MacBookAir6,2--a device from 2013 to early 2014, has documented linux support for mostly everything, so they don't have an issue with APP000D in the way. I'm not sure if this is helpful for anyone, it might be known already, but hopefully those more knowledgeable can help us figure out what to do next.
Also, it'd be beneficial if someone marked this CONFIRMED, it is certainly no longer NEW.

I got one of these 12-inch macbooks -- model A1534 -- the day they were released and am still waiting for a keyboard driver for Linux. Normally I run Gentoo GNU/Linux and the lack of a keyboard driver has prevented me from using this 12-inch macbook as much as I originally intended to. Let me know if there is anything I can do to help with testing. >> Should we raise a bounty? I will happily pledge $200 USD out of pocket for working keyboard and trackpad drivers for the 12-inch macbooks, specifically the A1534 model.
Can we use Bountysource or something like that to post it? I can add another $50 to the bounty.
Perhaps the best way is to ask Apple for help. But I'm not so optimistic about it. I have already sold my 2015 12-inch. I will not purchase a new one until there's an explicit solution.

I sent Apple an email through the web-forum linked below.

Why not just buy a device and donate to subsytem maintainer, i.e. Benjamin Tissoires?
Has anyone tested with a 4.7RC Kernel?
(In reply to OddJob from comment #58) > Has anyone tested with a 4.7RC Kernel? So far there's no driver in mainline, just an experimental (but working) out-of-tree driver at https://github.com/cb22/macbook12-spi-driver/
Thanks for pointing me to github and https://bugzilla.kernel.org/show_bug.cgi?id=108331. I am running 4.6, but unfortunately I have a 2015 model and am unsure of the steps to get the spi-pxa2xx driver working instead of the intel-loss driver in the 2016 model. It is encouraging to see some real progress on this though.

Since I tried to understand why the keyboard works in GRUB and not in the Linux, I have tried to install Ubuntu 12.04 .... And also no success. Oliver
(In reply to derarnold from comment #63) > Since I tried to understand why the keyboard works in GRUB and not in the > Linux, I have tried to install Ubuntu 12.04 .... And also no success. > > Oliver The EFI Firmware Volume in ROM contains drivers for most of the chips, including the keyboard. Those drivers are disabled once ExitBootServices() is called (see UEFI spec for details). That is called either by grub immediately before starting the kernel, or by the kernel itself if the efistub is used. After that an OS driver is supposed to take over. So the keyboard in grub works because of the firmware-provided driver.
Hi Lukas. New spin on this issue. Do you think there is any way we can use this drivers? Perhaps we can also analyst them to reverse engineer things? Oliver
(In reply to derarnold from comment #65) > New spin on this issue. Do you think there is any way we can use this > drivers? Perhaps we can also analyst them to reverse engineer things? They can't be used once ExitBootServices() has been called, we definitely need an OS-level driver such as the one Federico Lorenzi has begun. Yes of course they can be reverse-engineered, they can easily be extracted from the EFI firmware updates Apple ships using binwalk or UEFIExtract, then opened in a disassembler. However usually it's easier to reverse-engineer the macOS driver as it contains function names, more debug messages etc.
Any news?
Hi I own a macbook pro 12,1 with function keys. Has the same issues. I try to develop SPI HID driver and doing an attempt to use existing drivers prior developed to interface with apple USB HID devices. https://github.com/joelkraehemann/linux/blob/spi-hid-driver/drivers/hid/spi-hid/spi-hid.c It is based on the code of i2c-hid.c I'm complete beginner in kernel programming some help might be useful. Especially with the advanced topics like ACPI and a like. I have found some inconsistency of the SPI probe function. Might be we have to introduce some incompatibility by doing an additional parameter. In order to be usable by HID probe interface. Take a look at the probe parameters. http://lxr.linux.no/#linux+v4.9.4/include/linux/spi/spi.h#L253 http://lxr.linux.no/#linux+v4.9.4/include/linux/hid.h#L686 bests, Joël
This guy appears to have made some progress: https://github.com/cb22/macbook12-spi-driver but may have been unaware of the $905 bounty: https://www.bountysource.com/issues/35422234-macbook8-1-12-inch-early-2015-keyboard-and-trackpad-don-t-work Hopefully this will encourage them :-)
For everybody who's not following the git repository of the "applespi" driver (https://github.com/cb22/macbook12-spi-driver), you might be interested to hear that it got a lot of new features in the meanwhile: - no need to manually patch the ACPI DSDT table anymore - parameter to set if the keyboard has ANSI or ISO layout - working CAPS-lock LED - reliable working touchpad - working keyboard backlight (very soon) All in all it's now a pretty good working driver, suitable for productive use. Still not mainline, but I guess that'll eventually come as well.
Any idea if that includes the 2015 model? The README.md still indicates that it's primarily for the 2016 model

Not working here on a 4.11.4 kernel. Looks like I need to downgrade to ~4.6.5 and/or patch DSDT still. I'll try the earlier kernel first.

> Not working here on a 4.11.4 kernel. Looks like I need to downgrade to > ~4.6.5 and/or patch DSDT still. I'll try the earlier kernel first. According to other users it's working fine with the MacBook8,1 and MacBook9,1 without the need to patch the DSDT. Ensure you have the other required kernel modules loaded, as noted in the README. As the MacBook8,1 is the least tested device for this driver (and behaves quite differently) it could be helpful to add your experiences in https://github.com/cb22/macbook12-spi-driver/issues/9 > Does it work on macbook 12' 2017? So far this is untested, but given that the 12" MacBook 2017 is only a minor update compared to last year, it's likely that it works as well. I know for sure that it's working at least for the MacBook8,1, MacBook9,1 and all MacBookPro13,x.

One person has claimed that they also need to boot with "irqpoll" - that is still being investigated. [1] https://github.com/cb22/macbook12-spi-driver/issues/9#issuecomment-321717493
Thanks for the update, however when I posted that I already had CONFIG_X86_INTEL_LPSS=n and the latest applespi module, it still didn't appear to work for me, with or without irqpoll. Do we need the DSDT patching as well?
I've just tested again now with the newer applespi code and it seems to be working so far \o/ thanks
Well, the keyboard is at least, no trackpad yet
Oh, good - I was just writing a comment that you should try the latest driver since it has some fixes related to MacBook8,1 since your original post. Regarding the trackpad, that may be an initialization issue. Does dmesg show anything (dmesg | grep applespi)? Also, there's a pull request pending (https://github.com/cb22/macbook12-spi-driver/pull/45) for some touchpad init fixes - you might want to give that a try.
I wasn't able to spend much time investigating right now, just a quick test while at work. I'll check dmesg and try that PR tonight from home though. Thanks for the pointers

The code patched by > the mentioned commit is only executed when the above option is "y". Sorry, let me try again then: the bug can be avoid by either setting CONFIG_X86_INTEL_LPSS=n or by applying the patch (in which case CONFIG_X86_INTEL_LPSS can be set to y). Since that patch won't be in till kernel 4.14, I'm suggesting to folks who want a working keyboard and touchpad now that they build with CONFIG_X86_INTEL_LPSS=n, at least until the patch has made it into their kernel. Asking folks to change a config option appears to be slightly easier than having them apply a patch, at least for some distros. But of course patching instead will also fix it.
Hi Guys. I have tried Ubuntu 17.10 with Mainline Kernel 4.14-RC3 from the Ubuntu Repos http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.14-rc3/ and the keyboard and touchpad still do not work on the Macbook 2015. I thought all patches went into 4.14, right? Am I wrong? Regards Oliver

Am I wrong? AFAIU you still need to build applespi driver yourself on top of new kernel.
Ohh. Can I have build a stock kernel before (changed some configs). Can you help me how to build the driver? Do I need to build the kernel first? Where do I find the driver? Oliver
Do I need to follow this: https://github.com/cb22/macbook12-spi-driver ?
(In reply to derarnold from comment #90) > Do I need to follow this: https://github.com/cb22/macbook12-spi-driver? Yes. The fix in 4.14 is so you don't have to rebuild/reconfigure your existing kernel in addition to building the driver, but you still need to build the driver (upstreaming that is on the todo list, but we're not quite ready yet). A slightly updated README with more precise info is available at https://github.com/roadrunner2/macbook12-spi-driver/blob/9abd71c70f1489a0305a844af3dae1a7876e880c/README.md (this is queued to be merged into the main README).
Nice and thank you very much. I will try it out. Keep your fingers crossed ...
Can anybody test on v5.3-rc3 and confirm that it works? https://elixir.bootlin.com/linux/v5.3-rc3/source/drivers/input/keyboard/applespi.c
I'm about to close this bug since nobody appear to test and confirm the state. So I leave it in need info state for a while (day or two) and then close.
You can close this ticket. The driver was added to the kernel ages ago. I believe initial support was provided in kernel 4.14. Issues that occurred immediately afterwards were: Some distros did not initially enable the CONFIG_KEYBOARD_APPLESPI module in the kernel config. Some distros did not include the applespi module in their initramfs/initrd image, which would allow you to use the keyboard for decrypting a LUKS-encrypted drive at boot time. However, these were all distro-related issues (that had nothing to do with the kernel driver itself) that were resolved over time. In any case, I think the vast majority of all major distros (if not all) now include support for the CONFIG_KEYBOARD_APPLESPI module and have it included in their initramfs/initrd image as well. However, not all distros have the dependent modules included in their initramfs/initrd image. In fact, I just noticed on my Fedora 32 system that the (dependent) spi_pxa2xx_platform module is not included in the initramfs image. But, the the latest Ubuntu distro does have this module in its initrd image. I have a dracut config for this, so it's not something that I really ever look at. (going to submit a Fedora bug report for this now) Anyways, this is all distro-specific, the applespi kernel module works fine. Thank you to everybody who helped contribute to this!
Now closing based on comment #95. Please, submit tickets to the individual distro bug trackers.
