This changelog follows the format defined here: https://keepachangelog.com/en/1.0.0/
- Update version of BOOM included as a target in FireSim. The included version/configurations now reliably boot Linux and run SPEC. The FireSim NIC/network is also supported.
- Update IP addressing for simulated nodes to prevent a conflict between host IP range and simulation IP range. Simulations now live in 172.16.0.0/16 instead of 192.168.0.0/24.
- Update experimental SSH into target instructions to account for different interface names across EC2 instance types. This fixes the ability to access the internet from within simulated nodes.
- IMPORTANT:
aws-fpga-firesimis updated to the upstreamaws-fpga1.4.0 Shell release. This is a REQUIRED update for all users, as AWS will be removing support for old shells after September 1st, 2018. See this release note from AWS: https://github.com/aws/aws-fpga/blob/master/RELEASE_NOTES.md#release-140-see-errata-for-unsupported-features. In addition to pulling in the changes to the FireSim codebase for this release, you will need to launch a new manager instance using Amazon FPGA Developer AMI version 1.4.0. The documentation is updated to reflect this. - For users that cannot update directly to FireSim 1.3.0 because they cannot switch to the version of Rocket Chip updated in FireSim 1.2.0, a backport branch that adds the AWS FPGA 1.4.0 Shell to FireSim 1.1 is provided here: https://github.com/firesim/firesim/tree/firesim-1.1-aws-1.4.0-backport. In addition to pulling in the changes to the FireSim codebase for this branch, you will need to launch a new manager instance using Amazon FPGA Developer AMI version 1.4.0. The documentation is updated to reflect this.
- A new flag now allows zeroing FPGA-attached DRAM before simulation. This is enabled by default in the manager.
- New docs that explain how to
sshinto simulated nodes.
- FireSim now has beta support for simulating BOOM-based nodes. BOOM is the Berkeley Out-of-Order Machine, a superscalar out-of-order RISC-V Core. See the following page for usage instructions: https://docs.fires.im/en/1.2/Advanced-Usage/Generating-Different-Targets.html#boom-based-socs-beta
- Rocket Chip has now been bumped to a version from April 23, 2018.
Our first release of FireSim! Everything is a newly added feature, so check out the full documentation in the docs directory or the docs tagged 1.1.0 at https://docs.fires.im .
This was a closed-source, but free-to-use demo of FireSim released on AWS Marketplace with our AWS Compute Blog Post in August 2017. This was built from a very old version of FireSim and no longer supported, but noted here to explain why the versioning of this repo starts at 1.1.0.
