[dvsim] Implement LsfLauncher This is a first cut implementation of the LsfLauncher. There are several items left as TODOs - they will be addressed later. This implementation dispatches all targets (builds, runs, cov etc) as job arrays by default. Builds are run discretely (array of 1 job) since we consider each build to have specific job requirements that cannot be shared with other builds (cpu/mem/disk/stack usage settings - these will be added in future). Runs pertaining to a build is dispatched as an array. The associated changes made to other sources support the array generation. The job polling is not done by invoking bjobs or bhist, but by looking for the LSF job output file (unique for each array index), which gets written to only AFTER the job is complete. This offers a really fast way to test for completion rather than invoking bjobs or bhist, which bring the system to a crawl when invoked for 20k tests in flight. This largely works for now, but we need to explore other options such as using IBM's Platform LSF Python APIs (future work!). What launcher system to pick is decided by `DVSIM_LAUNCHER` variable. In addition, this PR also adds support for Python virtualenv to isolate project-specific python requirements that need to be met when running tasks on remote machines used by several other projects as well.

OpenTitan is an open source silicon Root of Trust (RoT) project. OpenTitan will make the silicon RoT design and implementation more transparent, trustworthy, and secure for enterprises, platform providers, and chip manufacturers. OpenTitan is administered by lowRISC CIC as a collaborative project to produce high quality, open IP for instantiation as a full-featured product. See the OpenTitan site and OpenTitan docs for more information about the project.
This repository contains hardware, software and utilities written as part of the OpenTitan project. It is structured as monolithic repository, or “monorepo”, where all components live in one repository. It exists to enable collaboration across partners participating in the OpenTitan project.
The project contains comprehensive documentation of all IPs and tools. You can access it online at docs.opentitan.org.
