0.0.3 - 2024-02-08

This version adds support to the RISC-V SBI Specification version 2.0 ratified.

Added

• Debug Console extension support
• pmu_counter_fw_read_hi in PMU extension
• Support for SBI CPPC extension
• Support for NACL and STA extensions
• Re-export HartMask, Physical, SbiRet and SharedPtr on sbi-rt library root

Modified

• SPI and RFNC extensions now use HartMask parameter

Fixed

• Minor document fixes on ConfigFlags and set_timer
• Document fixes on the HSM extension from SBI 2.0
• Extension ID of the Nacl and Sta extensions.

0.0.2 - 2022-10-10

In this version, we changed API style to trait-based type parameters, which would make it easier to check parameter types at runtime to reduce errors. If user chooses to use integer-impls feature, it would fall back to older style functions using integer types.

Added

• Trait-based type parameter for all extensions
• Feature integer-impls to allow fast prototyping with sbi-rt crate
• Feature legacy to gate the SBI legacy extension
• Documents on various functions

Modified

• Update sbi-spec to version 0.0.4, re-export Version structure
• Function probe_extension now returns an ExtensionInfo value
• Function pmu_num_counters returns a usize value
