The OSS4 patches are open-source. They are not documented. Your freedom of choice is not restricted by the OSS wiki, or any "sacred text", or Holy Scriptures. All the patches are kosher and fit for use. If a patch does not help to fix a problem, you may try another one.

The method of "trial and error" was invented in the Stone Age. Although, it does not always produce the desired results, it is, perhaps, the most democratic method of problem fixing. It can be used by anyone. No special education or technical knowledge is required.

You can easily create your own patches through the help of quilt

Code: Select all

$ man quilt

keenerd commented on 2013-11-11 20:51

I'd want the nastiest remaining bugs fixed first.
The two major issues were 'soundon' and the uninstall script.
'soundon' would sometimes take several minutes to finish. (That was isolated to a single line in the soundon script, didn't look deeper.)
The uninstall script had become a complete mess - it was supposed to put the alsa drivers back into place as if nothing happened. Instead you'd have to reinstall the kernel and reboot.

toksik commented on 2013-11-14 18:53

The soundon issue seems to be easy to fix:
ossvermagic.patch

...the deletion of the alsa modules could as well be replaced by some file in /etc/modprobe.d/ that blacklists these modules.

ALSA is a sort of Trojan. It cannot be easily deleted or blacklisted.
To disable ALSA, you may also need to update "initramfs"
_http://kernel-handbook.alioth.debian.org/ch-initramfs.html#s-initramfs-gen-tools

Code: Select all

$ man update-initramfs
DESCRIPTION
       The update-initramfs script manages your initramfs images on your local
       box.  It keeps track of  the  existing  initramfs  archives  in  /boot.
       There  are three modes of operation create, update or delete.  You must
       at least specify one of those modes.

       The initramfs is a gzipped cpio archive.   At  boot  time,  the  kernel
       unpacks  that archive into RAM disk, mounts and uses it as initial root
       file system. All finding of the  root  device  happens  in  this  early
       userspace.

The so-called "initramfs images" are stored in the /boot folder.
They can be named "initrd.img-$(uname -r)", or "initramfs-linux.img", or else.
It depends on the Linux distro.

You can unzip your initramfs image to an empty folder and examine its contents

How to blacklist a module on Ubuntu/Debian Linux
_https://linuxconfig.org/how-to-blacklist-a-module-on-ubuntu-debian-linux

There maybe a time when you need to disable some modules from being loaded during your system's boot time. In this "how to" we will discus some of the few ways how to blacklist module including its dependencies, that is, disable permanently module from loading during the boot time.

First, we need to know how to list all modules currently loaded by your Linux system:

Code: Select all

$ lsmod
....
ehci_hcd               40249  0
usbcore               128741  4 ehci_hcd,ohci_hcd,usbhid
usb_common             12354  1 usbcore
e1000                  86156  0
libata                140630  4 libahci,ahci,ata_piix,ata_generic
....

lsmod command lists all currently loaded kernel modules. The above lsmod output has been shortened. Let's say we are going to blacklist usbcore module. Before you unload or blacklist any module it is good to see what other modules depend on it:

Code: Select all

# modinfo -F depends usbcore
usb-common

From the above example we can see that usb-common module depends on usbcore. To blacklist a module without dependencies create a /etc/modprobe.d/blacklist.conf ( if non existing ) file and add line:

Code: Select all

blacklist usbcore

Once done update initramfs and reboot your system:

Code: Select all

# update-initramfs -u
# reboot

After reboot use lsmode to see whether module is present. In case that other modules are dependent on the module you are trying to blacklist, like in the above example, you will need to blacklist all dependent modules otherwise the initial module you have blacklisted would load anyway. Fortunately, there is a trick to blacklist all modules including their dependencies.

If from some reasons you are unable to blacklist modules and all its dependencies, make the module fail to load and thus also cause all dependent modules stop from loading. Add the following line to your /etc/modprobe.d/blacklist.conf to completely blacklist usbcore including all its dependent modules:

Code: Select all

install usbcore /bin/true

Update initramfs and reboot:

Code: Select all

# update-initramfs -u
# reboot

Just to be complete, please note that it is a good practice to create a separate module configuration file for each blacklisted module. For example if you wish to blacklist module e1000 than create separate /etc/modprobe.d/e1000.conf file.

Code: Select all

$ man true
       true - do nothing, successfully
       true [ignored command line arguments]

Code: Select all

$ man false
       false - do nothing, unsuccessfully
       false [ignored command line arguments]

On Ubuntu/Debian, the blacklisting of ALSA modules was already automatized:

Code: Select all

$ sudo dpkg-reconfigure linux-sound-base

Code: Select all

$ cat /usr/share/doc/linux-sound-base/README.Debian
The sound system can be selected by running:

    dpkg-reconfigure linux-sound-base

When ALSA is selected, all OSS modules are blacklisted for udev.
When OSS is selected, all ALSA modules are blacklisted for udev.

After blacklisting ALSA, you may want to examine the contents of initramfs

Code: Select all

$ lsinitramfs /boot/initrd.img-$(uname -r) | grep "soundcore\|snd"

and update initramfs (if needed).
