Inofficial Patches for AMD RAID linux kernel modules (rcraid.ko)
This is a third-party patch, it is not from AMD. AMD does not take any
responsibility for this patch. Read also the contents of the file LICENSE for
permissions and liability.
These patches bundle several fixes to the rcraid kernel module source code in order to make it compile under newer kernel versions than those officially supported in 2017 by AMD. It has been tested with Ubuntu 18.04, 18.10 and 19.04, but should run on other Linux flavors as well.
For a complete description of fixes, see file CHANGELOG.md.
Applying the patches is done by hand and cumbersome. A more convenient way may be to use the rcraid-dkms package from Thomas Karl Pietrowski (@thopiekar). If you still want to use this package, follow these instructions:
First download the AMD Linux RAID driver from the official AMD Raid driver page. (You need to accept the license.) Go to your download folder and unzip the downloaded file,
unzip raid_linux_driver_8_01_00_039_public.zip
Download the file rcraid.patch from this repository and put it in the same
folder you saved the above zip file in. Then issue
patch -p1 < rcraid.patch
The output looks like:
patching file driver_sdk/install
patching file driver_sdk/src/Makefile
patching file driver_sdk/src/common_shell
patching file driver_sdk/src/install_rh
patching file driver_sdk/src/install_suse
patching file driver_sdk/src/rc_init.c
patching file driver_sdk/src/rc_mem_ops.c
patching file driver_sdk/src/rc_msg.c
patching file driver_sdk/src/uninstall_rh
patching file driver_sdk/src/uninstall_suse
patching file driver_sdk/uninstall
Congratulations! You are done with patching.
Download the latest Ubuntu 18.04 image, install it on a USB stick and boot it in UEFI mode (turn of CSM module in BIOS). After booting, download the official AMD RAID driver. Open a shell and follow these instructions:
cd Downloads/
unzip raid_linux_driver_8_01_00_039_public.zip
sudo apt install git
git clone https://github.com/martinkarlweber/rcraid-patches.git
mv rcraid-patches/rcraid.patch .
rm -rf rcraid-patches/
patch -p1 < rcraid.patch
cd driver_sdk/
sudo apt install build-essential
sudo /bin/bash ./install
sudo rmmod ahci libahci
sudo modprobe rcraid
dmesg | less
If everything goes well, you will see an output similar to
rcraid: loading out-of-tree module taints kernel.
rcraid: module license 'Proprietary' taints kernel.
Disabling lock debugging due to kernel taint
rcraid: module verification failed: signature and/or required key missing - tainting kernel
