Introduction

The RISC-V Boot and Runtime Services Test specification defines a set of tests to verify if the requirements specified in RISC-V BRS specification are implemented. The tests specified in this specification are not intended to exhaustively verify the implementation. In most cases the tests only check for existence of the feature. Future versions of this specification may include more exhaustive tests.

The tests in this specification are documented use the following format:

TEST_ID# Test algorithm

AB_CAT_NNN_MMM

The CAT_NNN identifies a requirement in the RISC-V BRS specification. Each requirement is associated with one or more tests identified by MMM. The test IDs are prefixed with two character prefix - AB.

If character in position A is M then the test is for a requirement that MUST be supported and this test MUST pass. If character in position A is O then the test is for a requirement that SHOULD or MAY be supported; such tests may be skipped if the requirement is not implemented. The tests record if optional features were present in the test output log.

The character in position B indicates the nature of the test. If this character is F then the test exercises some or all of the functionality associated with the feature. If the character is E then the test determines for evidence that the feature is implemented (e.g., check ACPI tables) but does not functionally exercise the feature.

This specification groups the tests in the following broad categories:

  • Hart

  • SBI

  • UEFI

  • ACPI

  • SMBIOS
