Intel engineers are still working on DisplayPort 2.1 ALPM support for their Xe3P graphics, which is expected to provide power savings during periods of inactivity. The patches have been out for nearly a year, but they have yet to be merged.
Imagine you're using your laptop and you're not doing anything on it for a while. The DisplayPort 2.1 ALPM feature helps save power by putting the laptop into a low-power mode, but it can quickly wake up when you need it again. This is like a power-saving feature that helps your laptop be more efficient.
Analysis
DisplayPort 2.1 ALPM Overview
DisplayPort 2.1 introduces Advanced Link Power Management (ALPM) as a fast-wake, fast-sleep of a sink device for greater power savings especially with eDP laptops. DP ALPM can provide power savings during periods of inactivity yet respond rapidly when activity resumes.
Intel's Efforts on DisplayPort 2.1 ALPM
Intel engineers have been working on DisplayPort 2.1 ALPM support for their Xe3P graphics for nearly a year. The patches have been out there for a while, but they have yet to be merged. Recently, the fifth iteration of ALPM for Xe3P was sent out, which is a positive sign that the development is still active.
Implications for Linux Users
The support for DisplayPort 2.1 ALPM on Linux will provide power savings during periods of inactivity, which is especially beneficial for laptops with eDP displays. This feature is expected to be available on next-gen Nova Lake laptops, which are expected to be powered by Intel Xe3P graphics. Overall, the Linux support for Intel Nova Lake appears largely in order with Linux 7.3.
Key points
- Intel engineers are still working on DisplayPort 2.1 ALPM support for their Xe3P graphics.
- The patches have been out for nearly a year, but they have yet to be merged.
- The support for DisplayPort 2.1 ALPM on Linux will provide power savings during periods of inactivity.
- This feature is expected to be available on next-gen Nova Lake laptops, which are expected to be powered by Intel Xe3P graphics.
If the DisplayPort 2.1 ALPM support is successfully merged into the Linux kernel, it could lead to improved power efficiency on Linux laptops with Intel Xe3P graphics. This could be a significant benefit for users who value power-saving features.
If the DisplayPort 2.1 ALPM support is not merged into the Linux kernel, it could mean that Linux users with Intel Xe3P graphics will not have access to this power-saving feature. This could be a disappointment for users who were expecting this feature to be available.
