-# Contributing to Vortex on Github
+# Contributing to Vortex
 
-## Github Details
-- There are two main repos, `vortex` (public, this one) and `vortex-dev` (private)
-- todo: Most current development is on `vortex`
-- If you have a legacy version of `vortex`, you can use the releases branch or tags to access the repo at that point in time
+## Github
+Vortex uses Github to host its git repositories.
+There are a lot of ways to use the features on Github for collaboration.
+Therefore, this documentation details the standard procedure for contributing to Vortex.
+Development of Vortex is consolidated to this repo, `vortex` and any associated forks.
+Previously, there was active work done on a private repo named `vortex-dev`.
+`vortex-dev` has officially been deprecated and fully merged into this public repo, `vortex`.
+If you are returning to this project and have legacy versions of Vortex, you can use the releases branches to access older versions.
 
 ## Contribution Process
+In an effort to keep `vortex` organized, permissions to directly create branches and push code has been limited to admins.
+However, contributions are strongly encouraged and keep the project moving forward! Here is the procedure for contributing:
+
+1. Create a fork of `vortex`
+2. In your fork, create a branch that briefly explains the work you are adding (ie: `develop-documentation`) branches from `develop` and adds some documentation
+3. Make your changes on your new branch in your fork. You may create as many commits as you need, which might be common if you are making multiple iterations
+4. Since you are the owner of your fork, you have full permissions to push commits to your fork
+4. When you are satisfied with the changes on your fork, you can open a PR from your fork using the online interface
+5. If you recently made a push, you will get automatically get a prompt on Github online to create a PR, which you can press
+6. Otherwise, you can go to your fork on Github online and manually create a PR (todo)
+(todo): how to name and format your PR, what information you should add to the PR, does not need to be too strict if you are attending the weekly meetings*
+7. Github uses the following semantics: `base repository` gets the changes from your `head repository`
+8. Therefore, you should set the `base repository` to `vortexgpgpu/vortex` and the `base` branch to `develop` since active development should only be added to this branch
+9. And you should assign the `head repository` to `<your-github-username>/vortex` (which represents your fork of vortex) and the `base` branch to the one created in step 2
+10. Now that your intended PR has been specified, you should review the status. Check for merge conflicts, if all your commits are present, and all the modified files make sense
+11. You can still make a PR if there are issues in step 10, just make sure the structure is correct according to steps 7-9
+12. Once the PR is made, the CI pipeline will run automatically, testing your changes
+13. Remember, a PR is flexible if you need to make changes to the code you can go back to your branch of the fork to commit and push any updates
+14. As long as the `head repository`'s `base` branch is the one you edited, the PR will automatically get the most recent changes
+15. When all merge conflicts are resolved, changes are made, and tests pass you can have an admin merge your PR
+
+
 - You should create a new branch from develop that is clearly named with the feature that you want to add
 - Avoid pushing directly to the `master` branch instead you will need to make a Pull Request (PR)
 - There should be protections in place that prevent pushing directly to the main branch, but don't rely on it

 > Note: As it stands right now, there a few test suites which are not working due to this toolchain migration. We are working to determine an exact list of which ones are working and which ones are not. For now, if the repo builds at a minimum, then you can consider all these steps to have worked successfully.
 
 ## Choosing an Development Environment
+
 There are three primary environments you can use. Each has its own pros and cons. Refer to this section to help you determine which environment best suits your needs.
+
 1. Volvo
 2. Docker
 3. Local
 
 ### Volvo
+
 Volvo is a server provided by Georgia Tech. As such, it provides high performance compute, but you need valid credentials to access it. If you don't already have credentials, you can get in contact with your mentor to ask about setting your account up.
 
 Pros:
 
-1. Native x86_64 architecture, AMD EPYC 7702P 64-Core Processor (*fast*)
+1. Native x86_64 architecture, AMD EPYC 7702P 64-Core Processor (_fast_)
 2. Packages and difficult configurations are already done for you
 3. Consistent environment as others, allowing for easier troubleshooting
 4. Just need to SSH into Volvo, minimal impact on local computer resources
 5. VScode remote development tools are phenomenal over SSH
 
 Cons:
+
 1. Volvo is accessed via gatech vpn, external contributors might encounter issues with it -- especially from other university networks
 2. Account creation is not immediate and is subject to processing time
-3. Volvo might have outtages (*pretty uncommon*)
-5. SSH development requires internet and other remote development tools (*vscode works!*)
+3. Volvo might have outtages (_pretty uncommon_)

 ### Docker
 
@@ -44,18 +49,21 @@ Cons:
 2. Limited to your computer's performance, and Vortex is a large repo to build
 3. Will utilize a few gigabytes of storage on your computer for saving binaries to run the container
 
-
 ### Local
+
 You can reverse engineer the Dockerfile and scripts above to get a working environment setup locally. This option is for experienced users, who have already considered the pros and cons of Volvo and Docker.
 
 ## Setup on Volvo
+
 1. Clone Repo Recursively: `git clone --recursive https://github.com/vortexgpgpu/vortex-dev.git`
 2. Source `/opt/set_vortex_env_dev.sh` to initialize pre-installed toolchain
 3. `make -s` in `vortex-dev` root directory
 4. Run a test program: `./ci/blackbox.sh --cores=2 --app=dogfood`
 
 ## Setup with Docker
+
 Currently the Dockerfile is not included with the official vortex-dev repository, however you can quickly add it to repo and get started.
+
 1. Clone repo recursively onto your local machine: `git clone --recursive https://github.com/vortexgpgpu/vortex-dev.git`
 2. Download a copy of `Dockerfile.dev` and place it in the root of the repo.
 3. Build the Dockerfile into an image: `docker build --platform=linux/amd64 -t vortex-dev -f Dockerfile.dev .`

 ### Additional Docker Commands
+
 - Exit from a container (does not stop or remove it)
 - Resume a container you have exited or start a second terminal session `docker exec -it <container-name> bash`

 # FPGA Startup and Configuration Guide
 
+## Gaining Access to FPGA's with CRNCH
+If you are associated with Georgia Tech and need remote access to the FPGA's, you can utilize CRNCH's server.
+
+## What is CRNCH?
+
+**C**enter for **R**esearch into **N**ovel **C**omputing **H**ierarchies
+
+## What does CRNCH Offer?
+
+**The Rogues Gallery (RG)**: new concept focused on developing our understanding of next-generation hardware with a focus on unorthodox and uncommon technologies. **RG** will acquire new and unique hardware (ie, the aforementioned “*rogues*”) from vendors, research labs, and startups and make this hardware available to students, faculty, and industry collaborators within a managed data center environment
+
+## Why are the Rouges Important?
+
+By exposing students and researchers to this set of unique hardware, we hope to foster cross-cutting discussions about hardware designs that will drive future *performance improvements in computing long after the Moore’s Law era of “cheap transistors” ends*.
+
+## How is the Rouges Gallery Funded?
+
+Rogues Gallery testbed is primarily supported by the National Science Foundation (NSF) under NSF Award Number [#2016701](https://www.nsf.gov/awardsearch/showAward?AWD_ID=2016701&HistoricalAwards=false)
+
+## Rouges Gallery Documentation
+
+You can read about RG in more detail on its official documentation [page](https://gt-crnch-rg.readthedocs.io/en/main/index.html#).
+
+You can listen to a talk about RG [here](https://mediaspace.gatech.edu/media/Jeff%20Young%20-%20Rogues%20Gallery%20-%20CRNCH%20Summit%202021/1_lqlgr0jj)
+
+[CRNCH Summit 2023](https://github.com/gt-crnch/crnch-summit-2023/tree/main)
+
+## Request Access for Rouges Gallery
+
+You should use [this form](https://crnch-rg.cc.gatech.edu/request-rogues-gallery-access/) to request access to RG’s reconfigurable computing (vortex fpga) resources. You should receive an email with your ticket item being created. Once it gets processed, you should get an email confirmed your access has been granted. It might take some time to get processed.
+
+## How to Access Rouges Gallery?
+
+CRNCH resources do not require any VPN access for GT members so you can head to the web url for open on-demand: [rg-ood.crnch.gatech.edu](http://rg-ood.crnch.gatech.edu/)
+
+Alternatively, you can `ssh` into rg with: `ssh <your-gt-acctname>@rg-login.crnch.gatech.edu`
+
+(`ssh usubramanya3@rg-login.crnch.gatech.edu`)
+
+Once you’ve logged in, you can use Slurm to request other nodes within the testbed. See more information on Slurm at [this page](https://gt-crnch-rg.readthedocs.io/en/main/general/using-slurm.html).
+
+Note that you can also use VSCode to log into the Rogues Gallery via its terminal functionality. See [this page for more details](https://gt-crnch-rg.readthedocs.io/en/main/general/visual-studio-code.html).
+
+## **What Machines are Available in the Rogues Gallery?**
+
+Complete list of machines can be found [here](https://gt-crnch-rg.readthedocs.io/en/main/general/rg-hardware.html). 
+
+## Which Machine do we Need from RG?
+
+There are three primary nodes you might use. The table below summarizes:
+
+| Name | Device | Description |
+| --- | --- | --- |
+| flubber1 | u50 | can synthesize vortex |
+| flubber4 | u250 | missing HBM |
+| flubber5 | u280 | can synthesize vortex |
+
+
+*Note*: The `USERSCRATCH` folder is synchronized between all RG nodes. That means you can upload your files to `rg-login` and have them available on `flubber[1,4-5`. Changes on one node will be reflected across all nodes.
+
+## How to Access flubber for Synthesis?
+
+Now that you have the files prepared and available on the FPGA node, you can start the synthesis.  To run on hardware we need a rg-xilinx-fpga-hw cluster which includes **flubber[1,4-5]**. First `ssh` into the rouges gallery:
+
+```bash
+ssh <username>[@rg-login.crnch.gatech.edu](mailto:usubramanya3@rg-login.crnch.gatech.edu)
+```
+
+Then, to access the hardware node you need to `ssh` into flubber:
+
+```bash
+ssh flubber1
+```
+
+## Synthesis for Xillinx Boards
+
+XRT Environment Setup
+----------------------
+
+    $ source /opt/xilinx/Vitis/2023.1/settings64.sh
+    $ source /opt/xilinx/xrt/setup.sh
+
+
+Check Installed FPGA Platforms
+------------------------------
+
+    $ platforminfo -l
+
+
+Build FPGA image
+----------------
+
+    $ cd hw/syn/xilinx/xrt
+    $ PREFIX=test1 PLATFORM=xilinx_u50_gen3x16_xdma_5_202210_1 TARGET=hw NUM_CORES=4 make
+
+Will run the synthesis under new build directory: BUILD_DIR := "\<PREFIX>\_\<PLATFORM>\_\<TARGET>"
+
+The generated bitstream will be located under <BUILD_DIR>/bin/vortex_afu.xclbin
+
+Sample FPGA Run Test
+--------------------
+
+Ensure you have the correct opae runtime for the FPGA target
+
+    $ make -C runtime/xrt clean
+    $ TARGET=hw make -C runtime/xrt
+
+Run the following from your Vortex build directory
+
+    $ TARGET=hw FPGA_BIN_DIR=<BUILD_DIR>/bin ./ci/blackbox.sh --driver=xrt --app=sgemm --args="-n128"
+
+---
+
+The directory `hw/syn/xilinx/xrt` contains the makefile used to synthesize Vortex.
+
+For long-running jobs, invocation of this makefile can be made of the following form:
+
+`[CONFIGS=<vortex macros>] [PREFIX=<prefix directory name>] [NUM_CORES=<#>] TARGET=hw|hw_emu PLATFORM=<platform baseName> nohup make > <log filename> 2>&1 &`
+
+For example:
+
+```bash
+CONFIGS="-DL2_ENABLE -DDCACHE_SIZE=8192" PREFIX=build_4c_u280 NUM_CORES=4 TARGET=hw PLATFORM=xilinx_u280_gen3x16_xdma_1_202211_1 nohup make > build_u280_hw_4c.log 2>&1 &
+```
+
+The build is complete when the bitstream file `vortex_afu.xclbin` exists in `<prefix directory name><platform baseName>hw|hw_emu/bin`.
+
+## Running a Program on FPGA
+
+The blackbox.sh script in `ci` can be used to run a test with Vortex’s xrt driver using the following command:
+
+`FPGA_BIN_DIR=<path to bitstream directory> TARGET=hw|hw_emu PLATFORM=<platform baseName> ./ci/blackbox.sh --driver=xrt --app=<test name>`
+
+For example:
+
+`FPGA_BIN_DIR=`realpath hw/syn/xilinx/xrt/build_4c_u280_xilinx_u280_gen3x16_xdma_1_202211_1_hw/bin` TARGET=hw PLATFORM=xilinx_u280_gen3x16_xdma_1_202211_1 ./ci/blackbox.sh --driver=xrt --app=demo`
+
+## Synthesis for Intel (Altera) Boards
+
+To set up the environment, source the XRT setup.sh and other Xilinx scripts. For example:
+
+```
+source /opt/xilinx/xrt/setup.sh
+source /tools/reconfig/xilinx/Vivado/2022.1/settings64.sh
+source /tools/reconfig/xilinx/Vitis/2022.1/settings64.sh
+
+```

-The hardware configuration file `/hw/rtl/VX_config.vh` defines all the hardware parameters that can be modified when build the processor.For example, have the following parameters that can be configured:
-- `NUM_WARPS`:   Number of warps per cores
-- `NUM_THREADS`: Number of threads per warps
-- `PERF_ENABLE`: enable the use of all profile counters
-
-You configure the syntesis build from the command line:
-
-    $ CONFIGS="-DPERF_ENABLE -DNUM_THREADS=8" make
-
-OPAE Build Progress
--------------------
-
-You could check the last 10 lines in the build log for possible errors until build completion.
-
-    $ tail -n 10 <build_dir>/build.log
-
-Check if the build is still running by looking for quartus_sh, quartus_syn, or quartus_fit programs.
-
-    $ ps -u <username>
-
-If the build fails and you need to restart it, clean up the build folder using the following command:
-
-    $ make clean
-
-The bitstream file `vortex_afu.gbs` should exist when the build is done:
-
-    $ ls -lsa <build_dir>/synth/vortex_afu.gbs
-
-
-Signing the bitstream and Programming the FPGA
-----------------------------------------------
-
-    $ cd <build_dir>
-    $ PACSign PR -t UPDATE -H openssl_manager -i vortex_afu.gbs -o vortex_afu_unsigned_ssl.gbs
-    $ fpgasupdate vortex_afu_unsigned_ssl.gbs
-

 # Vortex GPGPU
 
-Vortex is a full-stack open-source RISC-V GPGPU.
+Vortex is a full-stack open-source RISC-V GPGPU. Vortex supports multiple *backend drivers*, including our C++ simulator (simx), an RTL simulator, and physical Xilinx and Altera FPGAs-- all controlled by a single driver script. The chosen driver determines the corresponding code invoked to run Vortex. Generally, developers will prototype their intended design in simx, before completing going forward with an RTL implementation. Alternatively, you can get up and running by selecting a driver of your choice and running a demo program.

 Vortex is a full-stack open-source RISC-V GPGPU. Vortex supports multiple *backend drivers*, including our C++ simulator (simx), an RTL simulator, and physical Xilinx and Altera FPGAs-- all controlled by a single driver script. The chosen driver determines the corresponding code invoked to run Vortex. Generally, developers will prototype their intended design in simx, before completing going forward with an RTL implementation. Alternatively, you can get up and running by selecting a driver of your choice and running a demo program.

+By exposing students and researchers to this set of unique hardware, we hope to foster cross-cutting discussions about hardware designs that will drive future *performance improvements in computing long after the Moore’s Law era of “cheap transistors” ends*. Specifically, the Rouges Gallery contains FPGA's which can be synthesized into Vortex hardware.
 
 ## How is the Rouges Gallery Funded?
 
@@ -32,68 +32,50 @@ You can listen to a talk about RG [here](https://mediaspace.gatech.edu/media/Jef
 You should use [this form](https://crnch-rg.cc.gatech.edu/request-rogues-gallery-access/) to request access to RG’s reconfigurable computing (vortex fpga) resources. You should receive an email with your ticket item being created. Once it gets processed, you should get an email confirmed your access has been granted. It might take some time to get processed.
 
 ## How to Access Rouges Gallery?
+There are two methods of accessing CRNCH's Rouges Gallery
+1) Web-based GUI: [rg-ood.crnch.gatech.edu](http://rg-ood.crnch.gatech.edu/)
+2) SSH: `ssh <your-gt-username>@rg-login.crnch.gatech.edu`
 
-CRNCH resources do not require any VPN access for GT members so you can head to the web url for open on-demand: [rg-ood.crnch.gatech.edu](http://rg-ood.crnch.gatech.edu/)
 
-Alternatively, you can `ssh` into rg with: `ssh <your-gt-acctname>@rg-login.crnch.gatech.edu`
-
-(`ssh gburdell3@rg-login.crnch.gatech.edu`)
-
-## Synthesis for Xilinx Boards
-First, you need to get access to the server with the Xilinx FPGAs.
+## Where should I keep my files?
+The CRNCH servers have a folder called `USERSCRATCH` which can be found in your home directory: `echo $HOME`. You should keep all your files in this folder since it is available across all the Rouges Gallery Nodes.
 
 ## **What Machines are Available in the Rogues Gallery?**
 
-Complete list of machines can be found [here](https://gt-crnch-rg.readthedocs.io/en/main/general/rg-hardware.html). 
-
-## Which Machine do we Need from RG?
-
-There are three primary nodes you might use for Xilinx FPGAs. The table below summarizes:
-
-| Name | Device | Description |
-| --- | --- | --- |
-| flubber1 | u50 | can synthesize vortex |
-| flubber4 | u250 | missing HBM |
-| flubber5 | u280 | can synthesize vortex |
-
-
-*Note*: The `USERSCRATCH` folder is synchronized between all RG nodes. That means you can upload your files to `rg-login` and have them available on `flubber[1,4-5`. Changes on one node will be reflected across all nodes.
-
-## How to Access flubber for Synthesis?
+Complete list of machines can be found [here](https://gt-crnch-rg.readthedocs.io/en/main/general/rg-hardware.html). Furthermore, you can find detailed information about the FPGA hardware [here](https://gt-crnch-rg.readthedocs.io/en/main/reconfig/xilinx/xilinx-getting-started.html).
 
-Now that you have the files prepared and available on the FPGA node, you can start the synthesis.  To run on hardware we need a rg-xilinx-fpga-hw cluster which includes **flubber[1,4-5]**. First `ssh` into the rouges gallery, if you have not already.
+## Allocate an FPGA Node
+Once you’ve connected to the CRNCH login node, you can use the Slurm scheduler to request an interactive job using `salloc`. This [page](https://gt-crnch-rg.readthedocs.io/en/main/general/using-slurm.html) explains why we use Slurm to request resources. Documentation for `salloc` can be found [here](https://gt-crnch-rg.readthedocs.io/en/main/general/using-slurm-examples.html). And here.
 
-```bash
-ssh <username>[@rg-login.crnch.gatech.edu](mailto:usubramanya3@rg-login.crnch.gatech.edu)
-```
 
-Once you’ve logged in, you can use Slurm to request an interactive job. First, view the available Slurm Partitions here [here](https://gt-crnch-rg.readthedocs.io/en/main/general/using-slurm.html). Then, the example requests can be found [here](https://gt-crnch-rg.readthedocs.io/en/main/general/using-slurm-examples.html).

-In our case we might run:

However, despite GPUs being one of the more popular accelerators across various applications, there is very little open-source GPU infrastructure in the public domain. We argue that one of the reasons for the lack of open-source infrastructure for GPUs is rooted in the complexity of their ISA and software stacks. In this work, we first propose an ISA extension to RISC-V that supports GPGPUs and graphics. The main goal of the ISA extension proposal is to minimize the ISA changes so that the corresponding changes to the open-source ecosystem are also minimal, which makes for a sustainable development ecosystem. To demonstrate the feasibility of the minimally extended RISC-V ISA, we implemented the complete software and hardware stacks of Vortex on FPGA. Vortex is a PCIe-based soft GPU that supports OpenCL and OpenGL. Vortex can be used in a variety of applications, including machine learning, graph analytics, and graphics rendering. Vortex can scale up to 32 cores on an Altera Stratix 10 FPGA, delivering a peak performance of 25.6 GFlops at 200 Mhz.},

 # Vortex GPGPU
 
-Vortex is a full-stack open-source RISC-V GPGPU. Vortex supports multiple *backend drivers*, including our C++ simulator (simx), an RTL simulator, and physical Xilinx and Altera FPGAs-- all controlled by a single driver script. The chosen driver determines the corresponding code invoked to run Vortex. Generally, developers will prototype their intended design in simx, before completing going forward with an RTL implementation. Alternatively, you can get up and running by selecting a driver of your choice and running a demo program.

-OPAE Environment Setup
-----------------------
-
-    $ source /opt/inteldevstack/init_env_user.sh
-    $ export OPAE_HOME=/opt/opae/1.1.2
-    $ export PATH=$OPAE_HOME/bin:$PATH

-    $ export LIBRARY_PATH=$OPAE_HOME/lib:$LIBRARY_PATH
-    $ export LD_LIBRARY_PATH=$OPAE_HOME/lib:$LD_LIBRARY_PATH
-
-OPAE Build
-------------------
-
-The FPGA has to following configuration options:
-- DEVICE_FAMILY=arria10 | stratix10
-- NUM_CORES=#n
-
-Command line:
-
-    $ cd hw/syn/altera/opae
-    $ PREFIX=test1 TARGET=fpga NUM_CORES=4 make
-
-A new folder (ex: `test1_xxx_4c`) will be created and the build will start and take ~30-480 min to complete.
-Setting TARGET=ase will build the project for simulation using Intel ASE.
-
-
-OPAE Build Configuration
-------------------------
-
-The hardware configuration file `/hw/rtl/VX_config.vh` defines all the hardware parameters that can be modified when build the processor.For example, have the following parameters that can be configured:
-- `NUM_WARPS`:   Number of warps per cores
-- `NUM_THREADS`: Number of threads per warps
-- `PERF_ENABLE`: enable the use of all profile counters
-
-You configure the syntesis build from the command line:
-
-    $ CONFIGS="-DPERF_ENABLE -DNUM_THREADS=8" make
-
-OPAE Build Progress
--------------------
-
-You could check the last 10 lines in the build log for possible errors until build completion.
-
-    $ tail -n 10 <build_dir>/build.log
-
-Check if the build is still running by looking for quartus_sh, quartus_syn, or quartus_fit programs.
-
-    $ ps -u <username>
-
-If the build fails and you need to restart it, clean up the build folder using the following command:
-
-    $ make clean
-
-The file `vortex_afu.gbs` should exist when the build is done:
-
-    $ ls -lsa <build_dir>/synth/vortex_afu.gbs
-
-
-Signing the bitstream and Programming the FPGA
-----------------------------------------------
-
-    $ cd <build_dir>
-    $ PACSign PR -t UPDATE -H openssl_manager -i vortex_afu.gbs -o vortex_afu_unsigned_ssl.gbs
-    $ fpgasupdate vortex_afu_unsigned_ssl.gbs
-
-FPGA sample test running OpenCL sgemm kernel
---------------------------------------------
-
-Run the following from the Vortex root directory
-
-    $ TARGET=fpga ./ci/blackbox.sh --driver=opae --app=sgemm --args="-n128"

+## Running the testcases
+
+```
+XLEN=32 ./run-test.sh testcase1 testcase2
+XLEN=64 ./run-test.sh testcase1 testcase2
+
+# or to run all default testcases
+XLEN=32 ./run-test.sh
+XLEN=64 ./run-test.sh
+```
+
+## Adding a new testcase
+
+The source code for the vector extension can be found in `sim/simx/execute_vector.cpp`.
+If you add support for a new vector instruction please go to `run-test.sh` and it to the default testcases.
+This will ensure your instruction is included in the regression test suite.
+
+## Updating the testcase binaries
+
+As `riscv-vector-tests` is still under development,
+we should periodically recompile the testscases and update the binaries.
+
+To update the test case binaries run:
+
+```
+XLEN=32 make -C ../../../third_party/ riscv-vector-tests
+XLEN=64 make -C ../../../third_party/ riscv-vector-tests
+```
+This requires Spike and Go to be installed on your machine.
+
+Then run the testcases that you want to update - this will automatically copy them e.g.:
+```
+XLEN=64 ./run-test.sh testcase1 testcase2
+```
+
+Finally use git to add the updated testcases to your commit (-f required due to .gitignore):
+```
+git add -f testcase1 testcase2
+```

+## Running the testcases
+
+```

+XLEN=64 ./run-test.sh testcase1 testcase2
+
+# or to run all default testcases
+XLEN=32 ./run-test.sh
+XLEN=64 ./run-test.sh
+```
+
+## Adding a new testcase
+
+The source code for the vector extension can be found in `sim/simx/execute_vector.cpp`.
+If you add support for a new vector instruction please go to `run-test.sh` and it to the default testcases.
+This will ensure your instruction is included in the regression test suite.
+
+## Updating the testcase binaries
+
+As `riscv-vector-tests` is still under development,
+we should periodically recompile the testscases and update the binaries.
+
+To update the test case binaries run:
+
+```
+XLEN=32 make -C ../../../third_party/ riscv-vector-tests
+XLEN=64 make -C ../../../third_party/ riscv-vector-tests
+```
+This requires Spike and Go to be installed on your machine.
+
+Then run the testcases that you want to update - this will automatically copy them e.g.:
+```
+XLEN=64 ./run-test.sh testcase1 testcase2
+```
+
+Finally use git to add the updated testcases to your commit (-f required due to .gitignore):
+```
+git add -f testcase1 testcase2
+```

 ## Adding a new testcase
 
-The source code for the vector extension can be found in `sim/simx/execute_vector.cpp`.
+The source code for the vector extension can be found in `sim/simx/vpu.cpp`.
 If you add support for a new vector instruction please go to `run-test.sh` and it to the default testcases.
 This will ensure your instruction is included in the regression test suite.

Subject: [PATCH 404/407] Add VM performance modeling with TLB integration

- Add TLB configuration parameters to VX_config.vh (TLB_SIZE, TLB_LINE_SIZE, etc.)
- Create TlbSim wrapper around CacheSim for TLB modeling
- Integrate TLB into CacheCluster with manual request/response flow
- Implement pending request tracking using HashTable
- Add internal ports (tlb_req_ports_, cache_rsp_ports_) for pipeline staging
- Performance impact: ~75% more cycles, 43% IPC reduction with VM enabled

Tested: Both VM_ENABLE and non-VM modes pass blackbox tests

Subject: [PATCH 405/407] Add simplified Page Table Walker (PTW) for realistic
 VM performance modeling

- Create ptw.h: Simplified sequential page table walker
- Sequential PT walks: One walk at a time (no complex MSHR)
- Multi-level support: PT_LEVEL memory accesses (2 for SV32, 3 for SV39)
- Correct VPN extraction and PTE address calculation per level
- Each PTE read goes through memory/cache hierarchy (realistic timing)
- Simple 2-state FSM: IDLE -> READING_PTE (per level) -> IDLE
- Integrate PTW into TlbSim between TLB and memory

Performance impact vs no-VM:
- Baseline (no VM): 12,086 cycles, IPC 0.356
- With VM + PTW: 33,764 cycles (+179%), IPC 0.128
- Realistic VM overhead modeling with sequential PT walks

Code: 185 lines (vs 310 in complex version), much simpler and clearer

Subject: [PATCH 406/407] Integrate physical address tracking and improve VM
 performance modeling

- Add physical address return parameter to MemoryUnit read/write functions
- Enhance PTW with proper SATP base PPN tracking and traversal logic
- Improve TLB integration with set_satp() method for SATP propagation
- Refactor cache_cluster.h for cleaner VM request handling
- Update system integration for physical address tracking throughout pipeline

Subject: [PATCH 407/407] Fix PTW implementation and improve TLB/PTW
 functionality

- Fix PTW memory request tag handling: initialize next_mem_tag_ to 1 to prevent duplicate requests for tag 0
- Remove duplicate memory access counter increment in PTW issue_pte_read
- Simplify PTW perf_stats() method to directly return perf_stats_ member
- Update cache cluster to properly aggregate PTW performance statistics
- Update VX_config.vh and VX_types.vh with TLB and PTW related definitions
- Update runtime utils to properly read and report PTW performance counters
- Improve emulator and socket handling for TLB/PTW operations

All changes verified with performance counter validation:
- PTW walks correctly tracked
- PTW memory accesses show perfect 2.0 ratio per walk (2-level page table)
- TLB hit/miss statistics properly reported
