Ubuntu 21.10 Crash
GMAzrael opened this issue · 19 comments
Upgraded from 21.04 to 21.10 with PopOS and it crashed on the firmware loading. https://gist.github.com/GMAzrael/ba85549089489bddbd992889a0804d50
Can confirm with a new install of PopOS 21.10 beta2 on a 2015 macbook pro. This module seems to not like linux 5.15.
It seems the Apple ACPI is doing something wrong. Did you also update to the latest firmware version in MacOS (normal MacOs updates) or just PopOS?
Didnt do any updates to MacOS for some time. My 2012 MBP wouldn't get Monterey. I didn't think my camera got a firmware update in some time.
I only updated PopOS
I'm not 100% sure if this contributes, but considering that building fails on my Pop 21.10 install (MBA 7,1), I could only assume?

Building on this exact laptop had been previously flawless; even on latest Apple firmware. This could be a separate issue, and if it is, please correct me, because I'm not very knowledgeable in terms of Linux.
I get the same Skipping BTF generation for /home/syl/bcwc_pcie/facetimehd.ko due to unavailability of vmlinux notice. Could this be the reason?
I did do a little research a good while back when I still used my MacBook, and all I could find is other DKMS modules failing to install because of an updated kernel. There's no "one size fits all" solution for this error in particular; every result I found had a different solution for their issue mentioned.
For those who end up here, you might need an updated pahole (version 1.23) to handle reading the new BTF tags for that kernel. (But I was able to get this facetimehd module to build just fine for the ubuntu mainline 5.17.1 kernel from https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.17.1/ for what it is worth.)
Updating pahole from the dwarves package can be a PITA though due to constantly moving targets of the btf header files in the linux kernel and the libbtf packages which the dwarves package in turn targets to build pahole.
I eventually just downloaded the pahole sources and installed from those to solve the issue.
The message I sent the debian pahole maintainer about this:
Any chance you would consider putting pahole 1.23 into testing/sid from https://git.kernel.org/pub/scm/devel/pahole/pahole.git ?
pahole 1.23 solves an issue with building the 5.17-rc1 kernel when ends with this error:

I was able to build a dkms package which worked just fine in 22.04 with kernel 5.17.1.
First install the 5.1.7.1 kernel from here: https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.17.1/
Then build and install the dkms package and the firmware files:
# Install required apps:
sudo apt install debhelper git unrar
# get source
git clone https://github.com/patjak/bcwc_pcie.git
cd bcwc_pcie/
sudo mkdir /usr/src/facetimehd-0.1
sudo cp -r * /usr/src/facetimehd-0.1/
sudo dkms add -m facetimehd -v 0.1
sudo dkms mkdsc -m facetimehd -v 0.1 --source-only
sudo dkms mkdeb -m facetimehd -v 0.1 --source-only
# Now install the deb package in /var/lib/dkms/facetimehd/0.1/deb
sudo dpkg -i /var/lib/dkms/facetimehd/0.1/deb/*.deb
cd /tmp
curl -OLf https://download.info.apple.com/Mac_OS_X/031-30890-20150812-ea191174-4130-11e5-a125-930911ba098f/bootcamp5.1.5769.zip
unzip bootcamp5.1.5769.zip
cd BootCamp/Drivers/Apple/
unrar x AppleCamera64.exe
dd bs=1 skip=1663920 count=33060 if=AppleCamera.sys of=9112_01XX.dat
dd bs=1 skip=1644880 count=19040 if=AppleCamera.sys of=1771_01XX.dat

dd bs=1 skip=1625840 count=19040 if=AppleCamera.sys of=1874_01XX.dat
sudo cp *.dat /lib/firmware/facetimehd/
# and then reboot
Do you need that specific kernel? Could it work with: 5.13.0-40-generic?
I am getting:
$ sudo dkms mkdsc -m facetimehd -v 0.1 --source-only
Error! DKMS tree does not contain: facetimehd-0.1
Build cannot continue without the proper tree.
I was just able to install it with:
# make
# make install
Using checkinstall did not work for me. It created a deb without the kernel module (i.e., *.ko file).
I'd prefer to automate this process. Is there a chance that we could have 1) a PPA for this module? and 2) a way for the module to be re-compiled when we install a new kernel?
Try
git clone https://github.com/patjak/bcwc_pcie.git
cd bcwc_pcie/
sudo mkdir /usr/src/facetimehd-0.1
sudo cp -r * /usr/src/facetimehd-0.1/
sudo dkms add -m facetimehd -v 0.1
sudo dkms mkdsc -m facetimehd -v 0.1 --source-only
sudo dkms mkdeb -m facetimehd -v 0.1 --source-only
I realize this thread is a few months old. I am currently trying to run the dkms mkdsc and the dkms mkdeb steps. It appears that the mkdsc and mkdeb actions have been removed from dkms on Ubuntu 22.10. I confess to being somewhat of a noob when it comes to compiling drivers. All the steps have run smoothly up to now, and I have just kind of hit a wall. Any help would be much appreciated. When I run apt to install dkms it gives me:
networkdude@MacBookPro:~$ sudo apt install dkms

dkms is already the newest version (3.0.6-2ubuntu2).

When I run dkms alone to view the options, I get this (note that mkdsc & mkdeb are missing):

Ubuntu 22.10 on a 2017 MacBook Pro 15" (14,3), kernel version 5.19.0-26-generic.
I am getting:

the howto has to be updated, it seem dkms in verson 3.x has dropped support for distro specific packagin
so this man does not work any more in debian stable, testing and unstable

I can confirm this last one, but I doubt it matters... Unfortunately this repo has been renamed and only half refactored, so working through it is quite confusing... The driver works however, right. It's quite something to run a 2014 wrbcam with a 6.5 kernel (Ubuntu 23.10)
I have Ubuntu 23 and Kernel 6.5 so is there a chance it works? The facetimehd camera is in my thunderbolt display not the macbook pro.
By any chance has anyone ever worked this out? I thought about downgrading dkms to 2.x (maybe 2.8.4-3: https://tracker.debian.org/pkg/dkms) but it's not found.
The Kernel is 6.8.0-31-generic on Ubuntu 24.04 LTS.
