Experimental Atheros AR81(31/32/51/52/61/62/71/72) Driver for 10.7/10.8

EXPERIMENTAL! UNSTABLE! WARNING! KITTENS!

 

Hi again everybody. After tinkering with updating the AtherosL1cEthernet drivers (http://www.insanelym...ver-for-107108/) I decided to try porting from scratch the newer ALX driver from here:

http://www.linuxfoun.../networking/alx

Much of what I said in the AtherosL1cEthernet thread also goes for this driver, so please browse over it quickly if you get a chance.

 

While the latest news update on the ALX page suggested they were stripping out support for the earlier drivers, the code for these seems to be still intact in the latest patches so it seemed worth trying to port, especially with many newer motherboard revisions apparently containing the AR8161 chip and causing people much frustration. Once again I've only been able to test this code on my AR8151. There are a lot of rough edges, but "release early, release often" as they say. There are essentially two low-level sections of code, one for the AR81(31/32/51/52) and another for the newer ones. I can't really vouch for the stability of the newer chipset code. Most of the low-level stuff is mostly portable and unmodified from the Linux code though.

 

Wake on LAN/demand works for me so far, but I haven't yet enabled TSO, VLAN and other advanced stuff. For now I'm just attempting to get the basic driver working.

 

Installing:

Use your favourite method of adding kexts to /System/Library/Extensions. Personally I prefer doing it manually from the terminal.

For testing or reporting bugs, please use the kext in the "Debug" subdirectory. This will output much more info to /var/log/system.log.

 

Remove any old version:

sudo rm -rf /System/Library/Extensions/ALXEthernet.kext

(Don't forget to also remove any potentially conflicting kexts from the Extensions directory, e.g. AtherosL1cEthernet.kext!)

 

Copy the new version from wherever you extracted it, such as Downloads:

sudo cp -r /Users/yourusername/Downloads/ALXEthernet/ALXEthernet.kext /System/Library/Extensions/

 

Update the kernel cache:

sudo touch /System/Library/Extensions

Then wait a couple of minutes or so before rebooting. This should trigger kextd to rebuild the cache.

(Alternatively you could completely remove the old cache first:

sudo rm -rf /System/Library/Caches/com.apple.kext.caches/*

But this is best ran from single user mode (-s) where kextd isn't active and watching for changes in the background.)

 

If you find your system becomes unbootable due to panics, the easiest way to fix this is to temporarily disable the ethernet card in the BIOS/UEFI, boot into Mac OS X and then perform the the first and last installation steps above.

 

Alternative (test) install:

To avoid breaking your system if the module is installed but panics every time, you can just test by installing to the temporary directory:

sudo cp -r /Users/yourusername/Downloads/ALXEthernet/ALXEthernet.ext /tmp/

 

Then load the module for testing:

sudo kextload /tmp/ALXEthernet.kext

 

The contents of /tmp will be automatically wiped upon reboot so you'll have to repeat these two steps each time.

 

Changelog:

1.0.2 - Bug fixes that should help clean up memory allocation problems at boot time (with a little luck). VLAN is now possible for anyone that needs it, but I've only tested it minimally.

 

1.0.1 - Bug fixes and refinements. Manually setting the link speed should work properly now and might be an option if autonegotiation is causing issues. The link watchdog timer should generally be working better now. Changed some Linux code that was automatically enabling MSI-X interrupts on newer chips. I have no idea if these are supported properly on Mac OS X, but to be safe I'd rather keep everything on plain old MSI for now.

 

1.0.0 - The initial release. Don't be fooled, it's likely very unstable!

 

Downloads:

The zip files are (hopefully) attached to this post. They contain the kext module and the GPL sourcecode. The kext in the "Debug" folder is mostly the same as the regular kext, but prints much more information to the system logs.

Like I said in the other thread: I'm just throwing this driver/code out there and seeing what happens. I can't provide serious help or even guarantee a reply if things don't work for anyone. Enjoy and please tell me what card type you have for any feedback if possible! :)

 

While kernel panics should hopefully not happen if everything is installed correctly, if anybody gets a regular panic and feels up to it then it would be incredibly useful for me if you were to enable verbose mode at boot with the -v flag and snap me a (readable) photograph of the panic screen along with which Mac OS X version they're using (e.g. 10.8.2) along with the driver version used (e.g. 1.0.1). I can then hopefully trace exactly where in the code things are going wrong. Usually these things are from buffer allocations gone horribly wrong.

Lenovo Y480 AR8161 Gigabit, had a couple of KPs (might have been some other problem but coincided with the kext install) and now seems to have settled. Everything seems to be working OK (DHCP IP, etc.), App Store, etc. Will keep you posted if anything develops. Thanks for getting this together, I think a lot of folks are looking for AR8161 solution.

Thank you for the feedback, it's good to know the AR8161 is at least (somewhat) working! :) I'll continue to improve what code I can as well as keep an eye out for newer low-level Linux code to merge. Sadly the ALX driver this is based on isn't even part of the stock-standard Linux kernel at this point as far as I can tell, but is a patch upon a patch upon a patch for adding experimental but badly-needed driver support to distros and is placed in a sub-directory ominously called "{censored}". :|

Confirming only one feature... AR8161 is recognized by the OSX 10.8.2. I use Belkin FD7050 v3 for internet as I do not have ethernet connection where my hackintosh is. iCloud and Appp store started working after install of this ALXEthernet kext.

 

My system:

GA H77 D3H

Core i5 3570k (using HD4000 graphics), no overclock

8 Gigs DDR3 1600 hz

Belkin FD7050 v3

WD 750 G HD for OSX, WD 1.5 TB for Win and data

350 watt powersupply that came with the Antac case

Asus DVD-RW Dont recall which one, really old, works reading DVDs

Connected to Samsung tv through HDMI

 

 

So far, 1. No HDMI audio (just doing research, havnt tried many kexts yet. 2. I have to switch my monitor off and on once at start when the screen becomes garbled.

Not tested - USB3

Other than the above, no KPs, no hickups. Been trying the build since two weeks so still newbe, have read a lot on these forums. Built the system with the advise here and everywhere on the internet but missed out on v1.1 using AR8161 (Issues were mixed with some people reporting success and others reporting problems but no mention of the chipset and kext not being available).

 

Saw great progress during these two weeks in terms of the ethernet problem.

App store access was essential to my build. This weekend trying to make Audio over HDMI work

 

Note: for some reason, this thread is really hard to find. Is there a way this could be popularized?

 

Gracias.

Hi OP, please check the attachments as it seems both zip's are the same 1.0.0 version? Thanks

 

I'm not quite sure what you mean. The top post contains both 1.0.0 and 1.0.1 under the Downloads subsection. They are both different files.

Hello, thanks for the driver! The first time I restart the computer after install the drive, the ethernet is working! However, subsequent restarts all result in kernal panic. I have attached screenshot. Please take a look. Thank!

 

I'm on 10.8.2, using the 1.01 version of the driver. My board is gigabyte h77 DS3H

 

Edit: looks like I can log into the system with boot ignore cache, but if not then kernel panic everytime.

 

Edit 2: due to some unknown reason I no longer experience kernel panic...I really don't know what happened. I just installed some app and nothing else. Thanks again for the great driver!

Thank you for the great debug info! I'm glad it's all running fine now for you anyway, but to be sure I'll plug the panic values into the debugger and see what comes up just in case. It's possible that your kernel cache simply got corrupted. I've had that happen to me once or twice in the past. It might have to do with deleting the cache while the kextd daemon has partially rebuilt it already. I might alter my installation instructions to be less "aggressive", I guess you could say. Typically kextd just rescans stuff anyway as soon as it detects a change in /System/Library/Extensions. Manually deleting the cache seems to mostly only be needed from single user mode.

I'm not too sure what the issue would be with the bootloader, unless you're trying to install things outside of /System/Library/Extensions. I don't have any issues with (recent build) Chameleon myself. I've heard good things about Clover though, so if it works for you I say stick with it. :)

Shailua,

 

Thanks for your reply! If those info can be of a little help then that's great. Today I experienced some strange freeze for my mac, I don't know for sure if it's the driver, but I suspect it may be related: whenever I try to upload my app build onto Apple's itunes connect through xcode, sooner or later during the uploading process the mac will freeze.

 

Thanks!

Shailua, you are a genius! :)

 

I haven't had time to test this out yet, but will be doing so shortly with my Atheros AR8161 Lan card in this Asus N56VM I have and will post my results!

 

Can't wait to test it out, actually gave up on running OSX on this laptop due to the Ethernet not being supported so this gives me new hope!

 

Now if I could only convince you to try and port over support for this Intel wireless card as well... :)

I am on Asus n56VM as well and the kext works perfectly (pretty fast) on Clover UEFI (great boot loader!) v2 in S/L/E But in chameleon the kext output an error message and is not loaded.

Hope it helps

it's worth noticing this problem.

Maybe you can avoid kp for chameleon by boot with -f

Thanks for the error report! That's one of my "oh no this should never happen!" messages, so it's easy for me to pinpoint. I've been tinkering with the memory allocation code a bit lately, so I've hopefully fixed it with a more suitable allocation method that isn't a holdover from the original AtherosL1cEthernet code. Asking the kernel to allocate chunks of contiguous physical memory tends to be rather touchy, but I don't think these cards tolerate anything less. I'll double check everything is still working okay on my desktop machine when I'm back home tomorrow and hopefully get 1.0.2 out soon after that. :)

      Hello.
      I have system unit Dell Vostro 3267 (i5-6400, Skylake). Information in signature.
      In this system block module installed Atheros AR9565 802.11 b/g/n Wireless Network Adapter, which, as I understand it, combines Wi-Fi - Atheros AR9565 and Bluetooth Qualcomm QCA9565.
       
      I managed to get working Wifi with kext from chunnann.

      Bluetooth works only if you first boot into Windows and then reboot into macOS from it. At the same time, you need to install drivers for bluetooth in Windows from the official Dell website, because the original drivers that Windows downloaded and installed itself - did not allow the bluetooth module to work even in Windows.
      In bluetooth settings, the power button was inactive and there was an eternal search for devices (if macOS was loaded immediately after the PC started). Enable button disable I cured just by adding the folder /kexts/Other kext BrcmBluetoothInjector by writing inside it in the Info.the plist file corresponds to the VendorID and ProductID of my bluetooth (which are displayed in the system report). BrcmBluetoothInjector_Mod.kext.zip
       
      I am disappointed that Windows is able to automatically download the firmware to the bluetooth module during the download, and Hackintosh macOS has not yet done such a kext.
       
      In the search for solutions to the problem I came across here are the options for the text:

      https://osxlatitude.com/forums/topic/2925-bluetooth-firmware-uploader/
      And here's a way - to use a virtual machine to the OS from it to download the firmware to the bluetooth module
      https://osxlatitude.com/forums/topic/10127-updated-nov-2017-fix-btfirmwareuploader-in-macos-high-sierra/
      Unfortunately, not one of these options did not help me to ensure that bluetooth worked when "cold" start the PC in macOS.
       
      1.
      I started to read more about kexts. In texte BrcmPatchRAM says that it is possible to add support for their bluetooth module in this kext. I downloaded the drivers for my bluetooth from the official site and extracted from .exe installer driver files themselves (This is easily done using 7-zip in Windows or using Keka in macOS). There were more files .dfu than others. As I found out .dfu files are compiled firmware files that the driver loads into the bluetooth module. In the instructions to BrcmPatchRAM States only .hex firmware files for Broadcom.
      I started looking for information on the Internet and found out that .hex files are the original "text" of the firmware as well .dfu is compiled .hex files.
      I immediately started looking for converters/decompilers/disassemblers from .in dfu .hex, but found only what's out .hex does .dfu file:
      https://github.com/pjsg/hex2dfu
      https://github.com/plietar/dfuse-tool
      https://github.com/kuro68k/ihex2dfu
      https://github.com/vpelletier/python-dfu
      As well as console utilities "dfu-tool" and "dfu-util" in Linux. I found out that dfu-util can be installed in macOS using Homebrew or use this option (it differs in functionality) https://github.com/the-darkvoid/dfu-util-osx
       
      2.
      I also learned that .dfu files are used in macOS /System/Library/Extensions/IOBluetoothFamily.kext/Contents/PlugIns/IOBluetoothUSBDFU.kext/Contents/Resources
      I think we should try to replace all of them on that file that Windows loads the bluetooth module (I think if you try to do so, you need to make several copies of this file and rename it to the original ones .dfu files to be deleted).
       
      3.
      As is the idea is just mine .dfu file rename to file .zhx and add it to the kext OS-X-BrcmPatchRAM (in BrcmFirmwareRepo.kext). But there is a problem - first, I don't know which one .dfu files are downloaded to my bluetooth, maybe even a few, because there are 3 files > 40 KB IN size and a lot of files ~ 2 KB in size.
       
      4.
      In "dfu-tool" and "dfu-util" I saw commands that extract firmware from the device. Maybe it will be possible to boot into Linux and if bluetooth starts working there, then try to extract the firmware from bluetooth with these utilities, and then add this firmware to kexts somehow.
       
      5.
      In the file BTFirmwareUploader.kex/Contents/MacOS/BTFirmwareUploader inside already have a list of firmwares, but they are in .hex format. Maybe there's a way to replace them with the contents .dfu file?
       
      I will continue to describe the ideas and results of the experiments. If you have any ideas or you can help to solve this problem, do not hesitate to write.
