AMD proposes a Linux kernel subsystem and driver for the Enhanced Serial Peripheral Interface (eSPI) standard.
Engineers working on low-level firmware or embedded Linux systems may soon have a standardized way to interact with eSPI hardware on AMD platforms. This reduces reliance on vendor-specific implementations and could simplify board bring-up and debugging. However, adoption will depend on upstream acceptance and hardware support.

AMD is pushing for a dedicated eSPI subsystem in the Linux kernel, including a new driver.
eSPI, originally developed by Intel, is now being adopted by AMD for its platforms.
The proposal aims to standardize eSPI support, reducing fragmentation in low-level firmware interfaces.
