+gem5 Specifc RISC-V tests
+=========================
+
+About
+-----
+
+This work provides assembly testing infrastructure including single-threaded
+and multi-threaded tests for RISC-V ISA in gem5. Each test targets an
+individual RISC-V instruction or a Linux system call. This work targets
+system call emulation (SE) mode in gem5.
+
+This work is based on the riscv-tests project.
+
+Link to the orignal riscv-tests projects can be found here:
+ https://github.com/riscv/riscv-tests
+
+Link to the original riscv-tests project's LICENSE and README can be found
+here:
+ https://github.com/riscv/riscv-tests/blob/master/LICENSE
+ https://github.com/riscv/riscv-tests/blob/master/README.md
+
+Specific commit ID that this work is based off:
+ 68cad7baf3ed0a4553fffd14726d24519ee1296a
+
+Changes from the orignal riscv-tests project
+--------------------------------------------
+
+1. Only rv64 tests are imported into this work
+
+The original project offers both rv64 and rv32 tests. Since the current
+implementation of RISC-V in gem5 is focused on its 64-bit version, only
+64-bit tests (rv64) are imported from the original project. Future work
+on 32-bit can easily integrate all 32-bit tests into gem5.
+
+2. New testing environment for gem5
+
+Since the original riscv-tests project is designed for bare-metal system (i.e.,
+without OS support), it offers several environments to control how a test
+interacts with a host machine (to-host communication). However, in gem5 SE
+mode, gem5 emulates an OS, and there is no host machine. Therefore, we
+developed a new testing environment called `ps` for gem5.
+
+This testing environment uses system call `exit` to return test results as an
+exit code of a particular test instead of writing them to a host machine. This
+environment requires the testing platform to implement/emulate at least `exit`
+system call.
+
+3. Minimal threading library written in assembly (`isa/macros/mt`)
+
+To simplify debugging multi-threading systems, we developed a minimal threading
+library that supports very basic threading functionality including creating a
+thread, exiting a thread, waiting for some thread(s) on a condition, and waking
+up some thread(s).
+
+Multi-threaded tests can rely on this library to manage multiple threads.
+
+4. RISC-V AMO, LR, and SC instruction tests (`isa/rv64uamt`)
+
+This is a set of assembly tests that target multi-core systems and test AMO
+instructions. This test set uses a minimal number of system calls (i.e., clone,
+mmap, munmap and exit) to create and manage threads. It does not use any
+complex sleep/wakeup mechanism to manage and synchronize threads to avoid
+adding extra unnecessary complexity. The major goal of this test set is to
+stress AMO instructions. Threads only synchronize at the end of their
+execution. The master thread does a spin-wait to wait for all threads to
+complete before it checks final results.
+
+5. Thread-related system call tests (`isa/rv64samt`)
+
+This is a set of assembly tests that target thread-related system calls and
+thread wait/wakeup behaviors. This set reuses some of the tests in
+`isa/rv64uamt` but uses more advanced futex system call operations to make
+threads wait and wake up in certain cases. This test set also checks functional
+behaviors of threads after a wait/wakeup operation.
+
+How to compile this test suite
+------------------------------
+
+1. Install RISC-V GNU toolchain. Source code and instruction on how to install
+it can be found here: https://github.com/riscv/riscv-gnu-toolchain
+
+2. Run `make`
+
+3. Test binaries are in `$GEM5/tests/test-progs/asmtest/bin/riscv/` ($GEM5 is
+your gem5 directory)
+
+How to run all tests
+--------------------
+
+1. Run `./run-tests.py`
+
+2. Test outputs are in ./test-summary.out
