HCL:ThinkpadX13s/porting

To be able to run some openSUSE images on the X13s, we needed to make multiple updates. Below is the list of the updates.

Kernel

To begin, we needed to make sure the required kernel modules where enabled (=m or =y in kernel config) for kernel-default package. Most of them were already enabled. This was an iterative process as we can notice additional requirements afterward, such as audio. Some of the updates:

• add QSEECOM : https://github.com/openSUSE/kernel-source/commit/574861dcf62ff003cf817de47d230559a12f59d2
• Audio:
  • https://github.com/openSUSE/kernel-source/commit/7859b9e038aaa2000a8be01c987b2f9622c6891a
  • https://github.com/openSUSE/kernel-source/commit/8be32dc439a60fc8f23ab372bd0093602f07f9d6

Also, as workarounds, we needed to pass some kernel options:

arm64.nopauth iommu.passthrough=0 iommu.strict=0

Installation image ISO

Despite the required kernel modules built in kernel-default package, the installation ISO (booted from USB) showed a black screen after grub. The following updates were required:

• https://github.com/openSUSE/installation-images/pull/660/files
• https://github.com/openSUSE/installation-images/pull/663/files

Live images

Despite the required kernel modules built in kernel-default package, the live ISO (booted from USB) showed a black screen after grub. The following update was required:

• https://build.opensuse.org/request/show/1128357

JeOS images

Despite the required kernel modules built in kernel-default package, the JeOS image (booted from USB) showed a black screen after grub. The following update was required:

• https://build.opensuse.org/request/show/1128282

There is still an open bug for JeOS boot from USB: https://bugzilla.suse.com/show_bug.cgi?id=1217314
