Ampere CentOS 7.5 Kernel wiki
This guide provides information regarding Linux kernel features and patches that apply to Ampere eMAG SoC. It provides a guideline regarding accepted, posting, and possible non-posted kernel patches that may assist developers in porting their kernels to have the same features as required to support Ampere eMAG SoC.
This document assumes a kernel version of 4.11 or 4.14. The stock kernel is located here https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/.
For any question, please contact Ampere eMAG support team at support@amperecomputing.com.
Majority of Ampere eMAG SoC features are already part of 4.11 kernel or 4.14 kernel. There is no additional high level feature missing as of this writing.
The table below shows repositories for Ampere eMAG SoC kernel. Ampere eMAG SoC kernels are based on stock kernel from CentOS.

There is no Ampere eMAG SoC kernel specific configuration file. It relies on the default configuration. In general, the default will include all that is needed. You can confirm that all required drivers are included by cross checking with the below table.

This section describes all patches related to Ampere eMAG SoC. In general, all patches are targeted for upstream. The only exception is patch marked with “NOUPSTREAM”. These patches - with no intention to upstream - may have one or more of the following reasons:
● Back ported patch and not applicable for upstream
● Patch will never be accepted upstream but may be beneficial to a specific version of the kernel
● Patch will never be accepted upstream as there is another solution in-flight
● Patch applicable to a specific individual and have no overall benefit to all or to the maintainer
Patches are separate into three categories – required, optional, and obsolete. Required patches are minimum patch required to have a bootable, working, and reasonable system performance. Optional patches are patches that provide extra features but not required to have a basic working system. Obsolete patches are patches that are no longer relevant.
These patches are required to support future BIOS change to support more efficient communication method with the boot processor.
