Hi Herbert, Please let me know if you have any comment for this patch series. Request you to consider these patches for next merge cycle. This patch series exports an in-kernel API which will be used by AMD-TEE driver. The patch series which introduces AMD-TEE driver can be found at: https://lkml.org/lkml/2019/12/6/17 Thanks, Rijo On 04/12/19 11:48 am, Rijo Thomas wrote: > The goal of this patch series is to introduce TEE (Trusted Execution > Environment) interface support to AMD Secure Processor driver.
