Some uses cases of Xen require suspending the platform. This is especially the case of client systems like laptops. This has been working for a long time with S3, although with some quirks. Newer platforms however have new approach for suspend - S0ix, and the support for S3 starts to disappear on Intel platforms newer than Tiger Lake. This presentation will show how does it work on S3, what quirks are necessary especially when PCI passthrough is involved. The second part of the presentation will focus on S0ix - what are the differences, and what changes in Xen (and related projects) are necessary to support it - based on the work done in Qubes OS.
