This blog post presents coreboot ([spelled in lower case characters](https://doc.coreboot.org/#spelling-of-coreboot),
even when it is the first word in a sentence) and Heads as an alternative to
Hostboot and Skiroot/Petitboot, respectively. The project was extensive, a list
of changes (incomplete!) can be found in [this issue](https://github.com/linuxboot/heads/issues/1729).
The work was paid through [Open Collective funds](https://opencollective.com/3mdeb_com)
and Insurgo personal investments, as well as 3mdeb investment and [NGI0 PET fund](https://nlnet.nl/project/AccessibleSecurity/).
It took 3 years so far, with results available as part of [Dasharo firmware distribution](https://www.dasharo.com/).

As described on the [project's page](https://coreboot.org),

> coreboot is an extended firmware platform that delivers a lightning fast and
> secure boot experience on modern computers and embedded systems.

{{< image src="blog/coreboot.png" width="900" height="900" >}}

It aims to do the bare minimum required to make the hardware usable and pass
the control to next program, called the payload. In case of Talos II, that
payload is Skiboot, with [few changes on top](https://github.com/Dasharo/skiboot/tree/raptor-cs_talos-2)
to make it play along with Heads.

Speaking of [Heads](https://github.com/linuxboot/heads), it is:

> a minimal Linux that (...) provides a secure, flexible boot environment for
laptops, workstations and servers.

Heads provides a bootloader menu that starts final operating system through
kexec call. This is very similar to what Petitboot does, but Heads puts
security above everything else.

It is possible to use coreboot without Heads, but not the other way around.
Heads depends on structures created by coreboot, which just aren't present when
booting with Hostboot.

## Building and flashing coreboot

To build coreboot image, follow the steps below:

1. Clone the coreboot repository:

```
git clone https://github.com/Dasharo/coreboot.git \
--depth=1 -b raptor-cs_talos-2/rel_v0.7.0
```

2. Start docker container:

```
cd coreboot
docker run --rm -it \
-v $PWD:/home/coreboot/coreboot \
-w /home/coreboot/coreboot \
-u "$(id -u):$(id -g)" \
coreboot/coreboot-sdk:0ad5fbd48d /bin/bash
```

3. Configure and start the build process inside of the container:

```
(docker) cp configs/config.raptor-cs-talos-2 .config
(docker) make olddefconfig
(docker) make
```
After image is built you can exit the container, either with `exit` or Ctrl+D.
To flash it to your platform:

0. Make sure you're running System Package v2.00, if not, get it from
[here](https://wiki.raptorcs.com/wiki/Talos_II/Firmware) and
[update/downgrade](https://wiki.raptorcs.com/wiki/Updating_Firmware#Updating_the_OpenPOWER_firmware).
Start the platform once so SEEPROM is also updated, then power off.

1. Copy images to BMC:

```
scp -O build/bootblock.signed.ecc root@<BMC_IP>:/tmp/bootblock.signed.ecc
scp -O build/coreboot.rom.signed.ecc root@<BMC_IP>:/tmp/coreboot.rom.signed.ecc
```

2. Log in to BMC through SSH:

```
ssh root@<BMC_IP>
```

3. Flash both partitions:

```
pflash -e -P HBB -p /tmp/bootblock.signed.ecc
pflash -e -P HBI -p /tmp/coreboot.rom.signed.ecc
```

4. Boot the platform as usual and enjoy coreboot running on Talos II:

[![asciicast](https://asciinema.org/a/zkQV1KhxY4n6IrlzssuvFHHS5.svg)]https://asciinema.org/a/zkQV1KhxY4n6IrlzssuvFHHS5

## Building and flashing Heads

Reminder: Heads requires coreboot. Instructions above **must** be performed
before flashing Heads. It also requires a [compatible USB security dongle](https://osresearch.net/Prerequisites#usb-security-dongles-aka-security-token-aka-smartcard)
and TPM (more about it later).

> Technically, TPM isn't a hard requirement of Heads, however its usefulness
> without it is very limited, up to a point where it doesn't have any advantages
> over Petitboot.

1. Just as earlier, start with cloning the repository:

```
git clone https://github.com/Dasharo/heads.git \
--depth=1 -b raptor-cs_talos-2/release
```

2. Start docker container:

```
cd heads
docker run --rm -it \
-v $PWD:/home/heads/heads \
-w /home/heads/heads \
-u "$(id -u):$(id -g)" \
3mdeb/heads-docker:2.4.0 /bin/bash
```

3. Build:

```
(docker) make BOARD=talos-2
```

This will take a while, wait for it to finish and then exit the container. In
the process, a coreboot image will also be built, but with slightly different
configuration. For security and reproducible images, `BUILD_TIMELESS` is always
enabled. While it actually strips file paths, it also removes file names and
line numbers from asserts in the code. It makes reporting and debugging
potential issues harder, so we suggest using coreboot built manually, at least
for the time being.

Steps for flashing Heads are similar to those done for coreboot.

1. Copy the Heads binary to the BMC (assuming in the Heads root directory):

```
scp -O build/zImage.bundled root@<BMC_IP>:/tmp/zImage.bundled
```

2. Log in to the BMC:

```
ssh root@<BMC_IP>
```

3. Flash the BOOTKERNEL partition with Heads:

```
pflash -e -P BOOTKERNEL -p /tmp/zImage.bundled
```

Answer yes to the prompt and wait for the process to finish. After that, start
the platform and begin [configuring Heads](https://osresearch.net/Configuring-Keys/).

## PNOR emulation

Flash device can be emulated by BMC, which is something we were often using for
development and testing. This saves a lot of time which would be spent flashing,
as well as reduces the wear of flash device.

However, this still requires System Package v2.00, and if this is different than
what real flash holds, SEEPROM will have to be updated when switching between
physical and emulated image. Also, this approach doesn't survive BMC reboots and
power losses. BMC doesn't have enough space to keep full PNOR image in
non-volatile memory, so `tmpfs` must be used for emulation. Don't try to put
more than one image in `tmpfs` or BMC **will** run out of RAM, which most likely
will require manual power cycle.

To start, obtain full flash image, either by downloading it from
[RaptorCS release page](https://wiki.raptorcs.com/wiki/Talos_II/Firmware) or
reading from existing image on BMC with:

```
pflash -r /tmp/talos.pnor
```

After that, you can "flash" the partitions mentioned earlier by adding
additional parameters to use the file instead of physical flash:

```
pflash -f -P <partition> -p <image_file> -F /tmp/talos.pnor
```

Change `<partition>` to one of `HBB`, `HBI`, `BOOTKERNEL` and `<image_file>` to
`/tmp/bootblock.signed.ecc`, `/tmp/coreboot.rom.signed.ecc` or
`/tmp/zImage.bundled`, respectively.

To tell BMC to present the contents of this file as flash, run:

```
mboxctl --backend file:/tmp/talos.pnor
```

Sometimes this command fails with a timeout, in that case run it again until it
succeeds.

> We've noticed that sometimes, despite no error message printed, physical flash
> was used anyway. It is easy to spot when one copy has Hostboot and the other
> has coreboot, but it can be missed when both images have different versions of
> coreboot. It caused us few hours of unnecessary debugging of issues that were
> already fixed...

With the file now mounted, platform can be started. Host firmware and OS
shouldn't be able to tell the difference, except for different reported erase
block size and maybe different access times.

To get back to original flash, run:

```
mboxctl --backend vpnor
```

It will report an error (`Failed to post message: Connection timed out`), but
will revert to physical device nonetheless. This can be confirmed by checking
the output of `mboxctl --lpc-state`:

```
root@talos:~# mboxctl --lpc-state
LPC Bus Maps: Flash Device
```

Since the file is now the full image with coreboot (and optionally Heads), it
can be simply written to flash, should you choose to accept it:

```
pflash -E -p /tmp/talos.pnor
```

## Noticeable differences between Hostboot and coreboot

For those wondering why we even started this project, here are some of the
differences between Hostboot and coreboot.

First of all, coreboot uses C, while Hostboot was written in C++. The latter can
be viewed as a complete operating system - it can use multiple threads
simultaneously, manages virtual memory and uses memory swapping (even before RAM
is trained). Each major [istep](https://wiki.raptorcs.com/w/images/b/bd/IPL-Flow-POWER9.pdf)
(IPL Step, which in turn stands for Initial Program Load) is a separate
application, with some common dynamically loaded libraries. coreboot, on the
other hand, runs all of the code in just 3 separate stages - bootblock, romstage
and ramstage. This allows for tighter linking process, which reduces the final
size of the code.

Another significant difference is reduced amount of RAS (Reliability,
Availability, Serviceability) features enabled in coreboot. Talos II is often
used as a workstation, and while RAS has its uses in servers (it is preferred
to start with partially working hardware than not starting at all), for home
users booting fast is usually more important. Because of that coreboot doesn't
support bad DQ masking for DRAM, it can also optionally skip initial RAM
scrubbing. Because of these reasons, as well as smaller size of code in general,
booting coreboot is significantly faster than Hostboot - some preliminary
results can be found [here](https://github.com/3mdeb/openpower-coreboot-docs/blob/main/devnotes/user_perspective.md).

Another technical difference is the way data is passed to Skiboot. Hostboot uses
HDAT - a format specific to this particular firmware. For coreboot, a device
tree conforming to a well-defined specification is used. In fact, Skiboot
internally converts HDAT to device tree anyway. At the moment, some information
is not presented by coreboot (https://github.com/Dasharo/dasharo-issues/issues/446,
https://github.com/Dasharo/dasharo-issues/issues/32), but those seem to be
rather cosmetic than anything else - if you know about something that requires
those pieces of information to be present, let us know.

## TPM

TPM is an integral part of security mechanisms added by Heads. As existing I2C
TPMs were [hard to obtain](https://github.com/3mdeb/openpower-coreboot-docs/blob/main/devnotes/tpm_over_i2c.md)
at the time we were working on this part of the project, and LPC TPMs couldn't
be used [due to the way POWER9 processor exposed access to LPC bus](https://github.com/3mdeb/openpower-coreboot-docs/blob/main/devnotes/tpm_over_lpc.md#tpm-over-lpc-interface),
we had to [consider other options](https://github.com/3mdeb/openpower-coreboot-docs/blob/main/devnotes/tpm.md).

The solution we ended up with was to create our own [I2C TPM 1.2 module](https://docs.dasharo.com/variants/talos_2/tpm-support/),
based on Infineon SLB9645TT1.2 chip. This chip isn't supported by drivers in
Hostboot and upstream Skiboot, to make use of it you have to use coreboot and
Dasharo's fork of Skiboot.

OCP China Day 2023 | Inspur Power Commercial Systems (IPS) joins hands with OPF to accelerate the implementation of POWER open source, open innovation

{{< image src="blog/OCP_China_Blog_image1.jpeg" >}}

On August 10, the 2023 Open Computing China Community Technology Summit (OCP China Day 2023) with the theme of "Open Momentum: Intelligent, Scalable, and Sustainable" was held in Beijing. In the age of wisdom, computing diversification, application diversification, and technological complexity are driving a new round of transformation in the data center. The open source and open community has become an important force to promote continuous innovation in the data center. Through global collaboration and innovation, we will work together to solve the problem of data center infrastructure. Major issues such as iteration and sustainable development.

Five open communities gather, to break the boundaries through open innovation

{{< image src="blog/OCP_China_Blog_image2.jpeg" caption="Meow Yee, President of the OpenPOWER Foundation" >}}

The deep integration of the digital economy and the real economy, as well as the digital world and the physical world, is driving data centers to accelerate innovation. However, increasingly complex technologies and new applications make it increasingly difficult for information technology service providers and enterprises to control the comprehensive innovation of data centers. Various open source and open communities with global collaboration as the core purpose have emerged as the times require, and have gradually become an important force for data center innovation.

In consideration of the coordinated development of data center software and hardware, cross-community cooperation has been increasingly valued by open source community leaders and members. This summit brought together community leaders from five open communities and organizations, including OCP, OCTC Open Computing Standard Working Committee, OpenPOWER Foundation (OPF), Dragon Lizard Community, and CXL Technology Alliance , to discuss how to build a highly collaborative software and hardware environment from different perspectives.

Meow Yee, President of the OpenPOWER Foundation (OPF) , said that open computing makes hardware agile innovation possible, and its value has been repeatedly verified in the past ten years. The OpenPOWER Foundation is committed to fully exploring the leading technical advantages of OpenPOWER-related assets such as Power ISA, Open FirmWare, and Power Cores, actively uniting member organizations all over the world, and building a more open, collaborative and win-win ecosystem, which not only accelerates innovation in the open hardware industry, but also at the same time supports and accelerates the innovation of open source software.

As digital technology becomes more and more complex, the progress of the community depends on inheriting and carrying forward the spirit of open source and open collaboration. Through a friendly and smooth collaborative development process and a complete community governance mechanism, while strengthening cross-community cooperation and sharing, and constantly expanding the boundaries of innovation.

**Open Computing Accelerates Hardware Innovation, and expands the OpenPOWER Technology Ecosystem**

The rise of open computing has greatly accelerated the pace of hardware innovation. The unique mode of technological innovation and unique design thinking are the core of open computing's continuous growth, while the construction of standards is the basis for the implementation of open computing. Thanks to open computing's equal emphasis on the development of technology and standards, more and more users can enjoy the dividends of open technology, and the spirit of open source and open collaboraiton becomes more deeply rooted within the technology community.

In fact, more and more OCP community members and users are paying more and more attention to technical solutions for sustainable development of data centers, and sustainable development has become a community consensus. The OpenPOWER Foundation promotes open innovation through core technologies such as open processors, memory interconnection interfaces, and peripheral device interconnection interfaces, as well as specifications, compliance testing, and product SIGs, and provides open hardware and software services for more than 300 members. , to jointly build the POWER ecosystem, promote community collaboration, and achieve sustainable development.

With the open source of POWER Instruction Set Architecture (ISA), POWER has become the only commercial architecture with a completely open system in the industry. Relying on POWER technology, IPS participates in OpenPOWER server design and development, OpenCAPI, and OMI design technology standards, to fully exploit POWER's leading enterprise-level computing capabilities. IPS has also designed and developed three generations of POWER products covering distributed storage, high-performance computing, high-density computing, big data computing and other fields. The Inspur K1 Power FP series servers accelerate the implementation of Power architecture innovations.

{{< image src="blog/OCP_China_Blog_image3.jpeg" caption="Yang Xu Deputy General Manager of Inspur Power Commercial Systems" >}}

The new-generation Inspur K1 Power FP5280G3 server, which adopts industry-leading dual-chip module technology and many other innovative technologies, also appeared in the OCP China Day exhibition area, which can flexibly respond to application requirements such as "general computing, large-capacity storage, hierarchical storage, and IO-intensive" , favored by the participants.

{{< image src="blog/OCP_China_Blog_image4.jpeg" caption="The new generation of Inspur K1 Power FP5280G3 server attracts attention" >}}

As a member of the OpenPOWER Foundation, Hexin Technology Co., Ltd., has developed leading high-end server processor chips for both domestic and international markets, based on the fully open source POWER architecture, and integrating the latest innovation of POWER processor technologies. The HX-C series has a leading virtualization platform and heterogeneous expansion capabilities. Inspur Power Commercial Systems has joined hands with Hexin Technology to create Inspur K1 Power CP series nationally-produced servers based on HX-C domestic processors, which will further promote the high-quality development of China's ICT industry.

{{< image src="blog/OCP_China_Blog_image6.jpeg" caption="Xu Yue Hexin Technology Co., Ltd. chip business leader" >}}

Driven by the idea of collaborative development of software and hardware, the integration of open source software and open hardware is accelerating, and open source technology will profoundly change the division of labor and cooperation mode of the global IT industry. In the future, more and more cross-community cooperation will further break the boundaries of innovation, and endow infinite possibilities for business innovation with a more open data center.

Since 2019, OCP China Day has become an annual event where industry leaders discuss open computing technology and innovation. This summit is hosted by OCP, the world's largest open computing community, and organized by Inspur Information. It focuses on issues such as data center infrastructure innovation and sustainable development, open computing innovation and ecological construction, and community collaborative innovation . Community leaders including the Committee, OpenPOWER Foundation (OPF), Dragon Lizard Community, CXL Technology Alliance, etc., technical experts, industry experts, and more than a thousand IT engineers and data center practitioners participated in the conference.

Microwatt is a multi-core processor capable of running at up to 2.3 GHz and using the Power ISA v3.0 specification. It can run on lower cost FPGAs. It has a memory management unit, privilege modes, interrupts, a floating-point unit, an interrupt controller and a level-2 cache, so that it can boot Linux.

The Microwatt processor was implemented using the [OpenROAD](https://theopenroadproject.org/) native design flow - [OpenROAD-flow-scripts](https://github.com/The-OpenROAD-Project/OpenROAD-flow-scripts) . It is available as part of the EDA cloud native solution in OpenPOWER. OpenROAD delivers an autonomous, No-Human-In-Loop, fully-integrated RTL-GDSII flow for the design of digital integrated circuits across a range of technologies. OpenROAD includes specific features for low power design that enabled the design to specification for Microwatt.

## Microwatt Design Flow using OpenROAD

The figures below show the OpenROAD flow using [OpenROAD-flow-scripts](https://github.com/The-OpenROAD-Project/OpenROAD-flow-scripts)

### OpenROAD High-level Flow

### OpenROAD Flow Scripts - A detailed Physical Implementation Flow

{{< image src="blog/openroad_image2.png" >}}

## Design Methodology

Microwatt was implemented using Skywater130nm (What production versions are supported- Is there a link to share about it? It consists of 6 macros and over 800K standard cells.

The hardware description for Microwatt was defined using Verilog in OpenPOWER. The RTL was synthesized in OpenROAD using Yosys to obtain a power-efficient mapping. [OpenSTA](https://github.com/The-OpenROAD-Project/OpenSTA) is an integrated and incremental timing and power analysis engine built into OpenROAD.

### Synthesis
The OpenROAD flow uses a synthesized netlist from Yosys to transform the RTL into an elaborated design with corresponding technology mapped primitives to generate an optimized netlist based on the input on specified timing constraints. This netlist was used to create the floorplan for detailed physical implementation.

### Placement and Routing

#### Floorplan Import design

Microwatt has 6 macros that were placed using the automatic macro placement in ORFS.

- RAM512 1 392.925
- RAM32 1RW1R
- Multiply_add_64x64
- RAM32_1RW1R
- Microwatt_FP_DFFRFile
- Multiply_add_64x64

macro placement

### Power Distribution

There are 5 metal layers in total in Microwatt. Metal 1 is horizontal and M2 is vertical followed by M3, M4 and M5 in horizontal direction. Power distribution is using M1, M4 and M5. The M1 layer is horizontal on the standard cell rails to enable power for the standard cells. VIA2 and VIA3 power vias are dropped. M4 power stripes and M5 power stripes are drawn. An alternate pattern of VSS and VDD pattern is followed

The figure below shows the PDN grid generated.

This is the complete PDN of the floor plan.

{{< image src="blog/openroad_image4.png" >}}

### Placement

Global Placement places standard cells to minimize wire length and avoid congestion during routing. Detailed placement further legalizes standard cell placement to remove overlaps and fix orientation for optimal routing. This step also includes the use of the resizer to optimize timing using techniques like buffer insertion, sizing, pin swapping etc.

#### How was timing optimization done using the resizer repair commands?

Using resizer commands the following is done at the placement step. The details are available in 3_4_resizer.log

1) 51 input buffers are added
2) 87 output buffers are added
3) 7237 buffers are added in 9711 nets
4) 23377 instances are resized

#### What tradeoffs were made for timing vs power?

We optimize for timing and less so for power. We do have some power recovery features in development that should be available soon.

#### Where is the static IR estimation report?

In 6_report.log when using ORFS

#### Did you run a simulation for power analysis?

We can provide a VCD (toggle counts) from simulation for improved accuracy. OR doesn't do simulation itself.

#### What kind of signoff was used to verify final timing and power (PrimeTime, Calibre etc.)

We have not done any signoff for final timing and power using Prime Time & Calibre.Only OpenROAD flow is being executed.

### Physical Verification

Once the physical layout (i.e., the GDS file) is complete, the design is ready for final verification and sign-off. This involves running a series of tests to ensure that the design meets all of the necessary requirements and specifications. Any issues that are found can be addressed, and the design can be re-synthesized and re-implemented until it meets all of the necessary criteria.

Finally, the design is ready for fabrication. The GDSII layout file is sent to a foundry, where the physical chip is manufactured. Once the chip is fabricated, it can be assembled into a larger system or device, such as a mobile phone or IoT device.

{{< image src="blog/openroad_image16.png" >}}

As a result, it is possible to create highly efficient and effective microwatt processors that can be used in a variety of different devices and applications, from mobile phones to IoT devices and beyond. The combination of the OpenPOWER microwatt processor and the OpenROAD design flow represents a powerful toolset for designers looking to create low-power, high-performance processors for modern electronics.

## The OpenPOWER HUB - An open, collaborative community enabling OpenPOWER

-----------------------------------------------------------------------

Centered around testing, development, and hardware integration on OpenPOWER hardware, the [OpenPOWER Foundation HUB](https://openpowerfoundation.org/hub/) (OPF HUB) is the place to begin or continue your next software project, whatever it may be. The OPF HUB resources are free to use, open, setup, reconfigurable, numerous, and backed by a dedicated HUB Special Integration Group. The HUB is a collaborative effort between the [OpenPOWER Foundation](https://openpowerfoundation.org/), Oregon State University [Center for Quantitive Life Sciences](https://cqls.oregonstate.edu/) (CQLS), Oregon State University [Open Source Lab](https://osuosl.org/) (OSUOSL), [University of Oregon](https://openpowerfoundation.org/hub/universityoforegon/), [VanTosh](https://openpowerfoundation.org/hub/vantosh/) and [Raptor Computing](https://openpowerfoundation.org/hub/raptorcomputingsystems/). Together with other OpenPOWER Foundation members, we form the [HUB Special Integration Group](https://openpowerfoundation.org/groups/hub/) (SIG), a group tasked solely with supporting and enabling others in starting on or porting projects to the POWER architecture and OpenPOWER platform.

The OPF HUB is a community and idea centered around a diverse set of people, platforms, and OpenPOWER hardware. It is a worldwide collection of users, providers, and SIG members; host to a diverse range of software, development stacks, operating systems, etc.; and of course, an ample collection of bleeding\-edge high performance computing (HPC) hardware, open for anyone to use and collaborate upon. The OPF HUB is not composed of the same hardware as the average cloud provider, because most clouds do not provide high end hardware like **OpenPOWER**. The systems that make up the OPF HUB are the same type of systems that went into the [Oak Ridge National Laboratory's 200 petaflop Summit supercomputer](https://www.olcf.ornl.gov/olcf-resources/compute-systems/summit/). The OPF HUB is also a community of people collaboratively engaging one another to develop, troubleshoot, plan, and push forward their own projects, as well as the OpenPOWER platform and idea.

The OPF HUB provided at OSU OSL includes access to bare metal machines, virtual machines (VMs), and Containers plus their orchestration/management. Users can interact with an OpenStack environment as well as Red Hat OpenShift Container Platform. All the OPF HUB hardware cannot easily be made ready to support everyone's next project without labor to manage, maintain, and make those resources readily available. We take pride in being able to provide the hardware resources for use, and have dedicated faculty researchers through the CQLS to help users access and make use of the OPF HUB.

The OpenPOWER HUB is an ever-changing resource that will continue to be upgraded with innovative technologies as they become available and meaningful to the world of HPC. Users and groups are invited to go to the main “[OpenPOWER HUB](https://openpowerfoundation.org/hub/)” website and find a provider to get free access to hardware resources and information. If you have questions about developing on the platform before or after you start your project, we invite you to join the [Power Developer eXchange community](https://community.ibm.com/community/user/powerdeveloper/home) to get support, exchange ideas, share experiences, and collaborate with Power experts and fellow developers.
