An nameless reader shared this report from Phoronix:
A pull request of early AMDGPU kernel graphics driver adjustments was submitted for DRM-Subsequent on Friday as among the early characteristic work accumulating for the Linux 6.4 kernel cycle.
Among the many AMDGPU kernel driver adjustments this spherical are various fixes affecting objects such because the UMC RAS, DCN 3.2, FreeSync, SR-IOV, varied IP blocks, USB4, and extra. On the characteristic facet, talked about subtly within the change-log are a couple of power-related additions… These additions are largely targeted on Van Gogh APUs, which is notably for the Valve Steam Deck and benefiting its graphics transferring ahead.
First up, this kernel pull request introduces a brand new sysfs interface for adjusting/setting thermal throttling. That is wired up for Van Gogh and permits studying/updating the thermal restrict temperature in millidegrees Celsius. This “APU thermal cap” interface is simply wired up for Van Gogh and appears to be Steam Deck pushed characteristic work in order that SteamOS shall be higher capable of handle the thermal dealing with of the APU graphics….
These energy options shall be uncovered by way of sysfs whereas Steam OS will wrap round them intelligently and probably some new UI settings knobs for these wanting extra management over their Steam Deck’s thermal/efficiency.
