GNU/Linux Ubuntu 21.04 Installing OEM Kernel – Quick-Start Guide
Hi! The Tutorial Shows You Step-by-step How to Install OEM Kernel in Ubuntu 21.04.x Hirsute Amd64 GNU/Linux Desktop.
What is the OEM Stack? Is a rolling Kernel similar to the HWE that include better support for some of the Latest Hardware.
Moreover, the OEM Kernel includes new Features and Fixes:
- Additional device drivers, e.g. i915 drivers to support new Intel graphics, iwlwifi to support new wireless cards or new Realtek card reader.
- New features, e.g. to support Thunderbolt security level or power saving for an existing device driver.
- Bug fixes. In many cases, fixes come from upstream, and so they will not only be applied to OEM kernel but also to stock Ubuntu kernel through the Kernel SRU (stable release update) process.
- Temporary workarounds. For critical issues where a fix does not yet exist at upstream, either the issue is newly found or the proposed fix has not been accepted by upstream, a workaround will be used to fix the issue temporarily, and will be replaced by a proper fix later, which is usually a fix that has been sanctioned by upstream.
