Support

Currently, OpenSBI fully supports SBI specification v0.2. OpenSBI also supports Hart State Management (HSM) SBI extension starting from OpenSBI v0.7. HSM extension allows S-mode software to boot all the harts a defined order rather than legacy method of random booting of harts. As a result, many required features such as CPU hotplug, kexec/kdump can also be supported easily in S-mode. HSM extension in OpenSBI is implemented in a non-backward compatible manner to reduce the maintenance burden and avoid confusion. That’s why, any S-mode software using OpenSBI will not be able to boot more than 1 hart if HSM extension is not supported in S-mode. Linux kernel already supports SBI v0.2 and HSM SBI extension starting from v5.7-rc1. If you are using an Linux kernel older than 5.7-rc1 or any other S-mode software without HSM SBI extension, you should stick to OpenSBI v0.6 to boot all the harts. For a UMP systems, it doesn’t matter. N.B. Any S-mode boot loader (i.e. U-Boot) doesn’t need to support HSM extension, as it doesn’t need to boot all the harts. The operating system should be capable enough to bring up all other non-booting harts using HSM extension.
