  2. SBI v0.3-rc1 released

Re: SBI v0.3-rc1 released

One thing that I'd like to see resolved for the 0.3 release is a precise specification for what sbi_probe_extension does. Right now the description says "Returns 0 if the given SBI extension ID (EID) is not available, or an  extension-specific non-zero value if it is available." However, every other extension listed in the spec fails to say what value should be returned if it is available.

I'd suggest that this function should indicate some sort of version number for each of the extensions, either just 1 to say that there haven't been multiple versions of any of the standard extensions or perhaps a value formatted like sbi_get_spec_version to encode more detailed information.

We have tagged the current SBI specification as a release candidate for
v0.3[1]. It is tagged as v0.3-rc1 which includes few new extensions and
cosmetic changes of the entire specification.
Here is a detailed change log:

- New extensions:
 - SBI PMU extension
 - SBI System reset extension
- Updated extensions:
 - Hart Suspend function added to HSM extension
- Overall specification reorganization and style update
- Additional clarifications for HSM extension and introduction section
- Makefile support to build html & pdf versions of the specification

We don't expect any significant functional changes. We will wait for
any further feedback and release the official v0.3 in a month or so.

Thank you for your contributions!
