+
+Suspend-to-idle and support for S0ix sleep is in the process of being added to FreeBSD.
+
+This will allow modern Intel and AMD laptops, some of which do not support ACPI S3 sleep, to enter low power states to increase battery life.
+
+Entry to S0i3 is now working reliably on the Framework 13 AMD Ryzen 7040 series laptops on FreeBSD 15.
+This required changes to LinuxKPI for DRM to know whether the system intends to enter S3 or S0ix: link:https://reviews.freebsd.org/D51591[D51591].
+
+These changes in turn required the creation of generic sleep types, separate from ACPI.
+Not all of these changes have yet been committed, but new hw.power.* sysctls will be created to choose the sleep type for various sleep state transition requests.
+
+The amdsmu driver, some ACPI changes and fixes, and GPIO interrupt servicing in amdgpio have been committed.
+
+A pre-built sleep testing image is now available to easily testing S0i3 entry on machines.
+Detailed instructions are on the webpage.

+With respect to the links, the blog post entry is still outdated.
