While the open RISC-V processor architecture has proven to be highly successful, one of the features that it hasn’t yet supported with the Linux kernel to this point has been system hibernation / suspend-to-resume, but that support is now on the way.
With RISC-V usage to this point being more around developer boards, IoT devices, and other cases where hibernation/suspend-to-disk isn’t normally used, it hasn’t been much of an issue. But as RISC-V presses more for consumer devices the hibernation/suspend-to-disk is obviously of more importance. Fortunately, RISC-V vendor StarFive has been working on hibernation support for RISC-V 64-bit and published the latest patches they are looking to get mainlined.
