Releasing Simulator-Bindings

List Simics-Base package versions in simics-api-sys/build.rs by running:

ispm packages --list-available --json \
    | awk '/\{/,EOF' \
    | jq -r '.availablePackages[] | select(.pkgNumber == 1000) | .version' \
    | tac \
    | grep -v pre \
    | sed -ne '/6.0.163/,$ p'

Update command at bottom of simics-api-sys/build.rs with any missing versions from the list
Install all supported Simics-Base package versions (update command with latest versions, here 6.0.207 and 7.0.20)

kinit; ispm packages -i 1000-6.0.{163..207} 1000-7.{0..20}.0

Build high-level bindings for any new features that merit inclusion. Not all features have high-level bindings, but most do. These high level bindings should utilize the versioned cfg() directives.
Run check script: ./check.sh
- This will report issues with formatting (C and Python formatting can be ignored for releases, markdown and Rust issues should be fixed)
- This will perform most checks done in CI including dependencies
- Any dependencies that are outdated or flag vulnerabilities in audits should be updated
- Any code which has breaking changes (very rare) should be fixed

Environment Variables

There are several environment variables which can be used for various purposes.

Build Flags

SIMICS_BASE: Specify the directory containing the Simics base package to build against e.g. SIMICS_BASE=/home/me/simics/simics-6.0.195
SIMICS_BINDINGS_NOCLEAN: Specify that the bindings should not have unknown items stripped. This results in messier and larger bindings files, but can be used if targeting a version of Simics which the bindings have not yet been explicitly updated to target. Also speeds up compilation, so this can be used in .cargo/config.toml to speed up rust-analyzer runs.

[env]
SIMICS_BINDINGS_NOCLEAN = "1"

Metadata Overrides

SIMICS_PACKAGE_PACKAGE_NAME: Override the package-name field of the package.metadata.simics Cargo.toml table
SIMICS_PACKAGE_PACKAGE_NUMBER: Override the package-number field of the package.metadata.simics Cargo.toml table
SIMICS_PACKAGE_NAME: Override the name field of the package.metadata.simics Cargo.toml table
SIMICS_PACKAGE_DESCRIPTION: Override the description field of the package.metadata.simics Cargo.toml table
SIMICS_PACKAGE_HOST: Override the host field of the package.metadata.simics Cargo.toml table
SIMICS_PACKAGE_VERSION: Override the version field of the package.metadata.simics Cargo.toml table
SIMICS_PACKAGE_BUILD_ID: Override the build-id field of the package.metadata.simics Cargo.toml table
SIMICS_PACKAGE_BUILD_ID_NAMESPACE: Override the build-id-namespace field of the package.metadata.simics Cargo.toml table
SIMICS_PACKAGE_CONFIDENTIALITY: Override the confidentiality field of the package.metadata.simics Cargo.toml table
SIMICS_PACKAGE_TYPE: Override the type field of the package.metadata.simics Cargo.toml table
SIMICS_PACKAGE_DOC_TITLE: Override the doc-title field of the package.metadata.simics Cargo.toml table

Testing Flags

SIMICS_TEST_LOCAL_PACKAGES_ONLY: Do not download new package versions for test environments and only copy locally installed packages instead. Tests which explicitly depend on non-installed packages will fail.
SIMICS_TEST_CLEANUP_EACH: Clean up after each test instead of leaving the package installation directory. Use if the package versions used in the test change, but there is no need to use if only the code under test has changed (and not the test environment configuration).

Build Directives

The Simics bindings have some version-dependence on the underlying C API. The emit_build_directives function from the simics-build-utils crate emits configuration directives used in the build process to conditionally enable features that aren't compatible with all supported SIMICS versions, based on the SIMICS version of the low level bindings. This is not needed for all consumers of the API, but is useful for consumers which need to remain compatible with a wide range of SIMICS base versions.

If your consumer of the Simics API needs to conditionally enable/disable its own functionality depending on the version compiled against, you can call emit_build_directives in your build.rs script and use the directives like:

#![allow(unused)]
fn main() {
#[cfg(any(simics_version = "6.0.191", simics_version = "7"))]
}
