New Raspberry Pi OS Looks Like Windows XP
https://www.tomshardware.com/news/windows-raspberry-pi-xp-linux-raspbian-professional
While you can’t quite have the full Windows XP experience on a Raspberry Pi, this Linux Raspbian XP Professional operating system (OS) from Pi Lab definitely gets close. It’s designed to run on the Raspberry Pi 4, the only model powerful enough to handle it.
Linux Raspbian XP Professional comes with a number of features that are reminiscent of the old XP OS. It has a working Start Menu complete with a usable search bar at the top. All of the menus, icons and taskbars have the classic bubbly XP. They even included the complete LibreOffice suite in lieu of Microsoft Office.

If you’re basing your next system design on the Arm architecture, the Raspberry Pi Foundation’s various boards are an intriguing alternative to “rolling” your own hardware, particularly for modest production volumes. Their longevity, widespread adoption, and multiple sourcing options have translated into robust availability and cost-effective pricing. Board variants based on multiple CPU core generations are available; they also have varying form factors, power consumption specs, clock speeds, and connectivity, memory and other peripheral types and amounts.
The boards’ standardized HAT (hardware attached on top) connectors and software protocols further expand their peripheral capabilities, as well as bolstering their debugging and other development support. And when system shipment volumes reach the point where it makes fiscal sense for you to take over hardware building block manufacturing responsibilities yourself, the boards’ open-source specifications make the transition a straightforward one.

ZRAM BOOSTS RASPBERRY PI PERFORMANCE
https://hackaday.com/2020/05/20/zram-boosts-raspberry-pi-performance/
Linux is a two-edged sword. On the one hand, there’s so much you can configure. On the other hand, there’s so much you can configure. It is sometimes hard to know just what you should do to get the best performance, especially on a small platform like the Raspberry Pi. [Hayden James] has a suggestion: enable ZRAM and tweak the kernel to match.
Although the post focuses on the Raspberry Pi 4, it applies to any Linux system that has limited memory including older Pi boards. The idea is to use a portion of main memory as a swap file. At first, that might seem like a waste since you could use that memory to, you know, actually run programs. However, the swap devices are compressed, so you get more swap space and transfers from these compressed swap devices and main memory are lightning-fast compared to a hard drive or solid state disk drive.
Raspberry Pi Performance: Add ZRAM and these Kernel Parameters

Raspberry Pi OS: Why It’s No Longer Called ‘Raspbian’
https://www.tomshardware.com/news/raspberry-pi-os-no-longer-raspbian
The new, 64-bit operating system doesn’t use software from the Raspbian project at all, instead taking its “userland,” the part of the OS that floats above the Kernel, from Debian arm64. In a post on the raspberrypi.org forums, Green explains that he doesn’t want the Raspbian name used for something that doesn’t incorporate code from his project.
“For a while now raspberry pi have been considering 64-bit images,” Green wrote. “Eben [Upton, founder of Raspberry Pi] sent me an email asking my opinion about nomenclature and I expressed that I would not be pleased about the use of the name “Raspbian” for images that did not contain anything from Raspbian.”
Green also wrote that he plans to continue the Raspbian project, which will undoubtedly continue to be used to build the 32-bit version of Raspberry Pi OS. Considering that many models of Raspberry Pi, including the very-popular Raspberry Pi Zero, will never work with a 64-bit OS, the 32-bit platform will continue to be important if not dominant for years to come.

ADDING PCIE TO YOUR RASPBERRY PI 4, THE EASIER WAY
https://hackaday.com/2020/07/01/adding-pcie-to-your-raspberry-pi-4-the-easier-way/
Ever since people figured out that the Raspberry Pi 4 has a PCIe bus, the race was on to be the first to connect a regular PCIe expansion card to a Raspberry Pi 4 SBC. Now [Zak Kemble] has created a new approach, using a bridge PCB that replaces the VL805 USB 3 controller IC. This was also how the original modification by [Tomasz Mloduchowski] worked, only now it comes in a handy (OSHPark) PCB format.
After removing the VL805 QFN package and soldering in the bridge PCB, [Zak] confirmed that everything was hooked up properly and attempted to use the Raspberry Pi 4 with a PCIe extender. This showed that the Raspberry Pi would happily talk with a VL805-based USB 3.0 PCIe expansion card, as well as a Realtek RTL8111-based Ethernet card, but not a number of other PCIe cards. Exactly why this is is still unclear at this point.

Raspberry Pi’s Eben Upton has confirmed that a Compute Module 4 is in the works, and that it may expose both PCIe and NVMe connectivity for external hardware.
Raspberry Pi Compute Module 4 to Expose its PCIe Gen. 2 Lane at the Edge for High-Speed Peripherals
https://www.hackster.io/news/raspberry-pi-compute-module-4-to-expose-its-pcie-gen-2-lane-at-the-edge-for-high-speed-peripherals-06cda3b00c1c
New, more powerful COM based on the same SoC as the Raspberry Pi 4 due out within the next year, says Eben Upton.
Raspberry Pi Foundation co-founder Eben Upton has confirmed that a Raspberry Pi Compute Module 4 is in the works, and that it may expose both PCI Express (PCIe) and Non-Volatile Memory Express (NVMe) connectivity for external hardware.
The launch of the Raspberry Pi 4 Model B brought with it not only a major upgrade to the CPU, GPU, and RAM on the popular single-board computer, but a big boost in peripheral connectivity: The board’s first PCI Express (PCIe) support, used to drive two USB 3.0 ports as well as provide the family’s first gigabit-capable Ethernet port.
This PCIe connectivity isn’t exposed externally, however, leading some to remove the USB 3.0 controller chip and replace it with a pass-through board — allowing external PCIe devices to be connected to the board, driver support permitting.
The Compute Module range takes the Raspberry Pi SBC concept and switches it into a computer-on-module (COM) format. With no connectors of its own bar a SODIMM-format edge connector, the Compute Module is entirely reliant on a breakout board for connectivity — and the Compute Module 4 will use this edge connector to expose the PCIe Gen. 2 lane, no hacking required.
Upton is silent on pricing for the Compute Module 4, as well as a firm launch date — beyond stating that it would be out within the next year.

https://www.theregister.com/2020/09/29/xen_on_rpi_4/
The Xen Project has ported its hypervisor to the 64-bit Raspberry Pi 4.
The idea to do an official port bubbled up from the Xen community and then reached the desk of George Dunlap, chairman of the Xen Project’s Advisory Board. Dunlap mentioned the idea to an acquaintance who works at the Raspberry Pi Foundation, and was told that around 40 percent of Pis are sold to business users rather than hobbyists.
With more than 30 million Arm-based Pis sold as of December 2019, and sales running at a brisk 600,000-plus a month in April 2020, according to Pi guy Eben Upton, Dunlap saw an opportunity to continue Xen’s drive towards embedded and industrial applications.

Packing the same BCM2711C0 SoC as the full-size Raspberry Pi 4, are these system-on-modules the new must-have gadgets?
Two years after launching the Raspberry Pi Compute Module 3+, and four years after the Raspberry Pi Compute Module 3, the Raspberry Pi Foundation has a new system-on-module (SOM) — but while it offers considerably boosted performance, it does away with backwards compatibility for existing carrier boards.
The Compute Module 4, then, should not surprise: It’s a system-on-module built on the Broadcom BCM2711C0, the same system-on-chip which powers the Raspberry Pi 4. Like the full-size Raspberry Pi 4, the four 64-bit Arm Cortex-A72 cores are clocked at 1.5GHz — with no sign of the same clock-speed reduction as the Compute Module 3+ — and buyers have a choice of 1GB, 2GB, 4GB, or 8GB of LPDDR4 RAM.

Hands-On with the Raspberry Pi 400, the First “Consumer Product” Raspberry Pi
https://www.hackster.io/news/hands-on-with-the-raspberry-pi-400-the-first-consumer-product-raspberry-pi-2718c6b45ad3
Designed to be an “object of desire,” the Raspberry Pi Foundation’s new device is a marked departure from the norm — and faster than a Pi 4.
It’s only been two weeks since the Raspberry Pi Foundation unveiled the Raspberry Pi Compute Module 4 and Compute Module 4 system-on-module products, but it has another trick up its sleeve: The Raspberry Pi 400, the first consumer-centric product in its portfolio — and a throwback to the early days of affordable personal computing, originally floated under the internal name “Project Commodore 64,” before “Project Gamma” was picked to make any possible leaks less revealing of the project’s intentions.
The electronics inside the Raspberry Pi 400, which until you turn to look at the ports at the rear looks like a clone of the existing Raspberry Pi Keyboard, are effectively the same as the ones you’ll find powering a Raspberry Pi 4 or the newly-released Compute Module 4. There’s a BCM2711 SoC with four Arm Cortex-A72 cores and a VideoCore VI graphics processor, 4GB of LPDDR4 memory
and a microSD slot for storage.
Conclusion
For owners of a Raspberry Pi 4, there’s no particular reason — other than it being, as Upton has it, “an object of desire” — to move to the Raspberry Pi 400. It’s 300MHz faster, sure, but that same level of overclock and more is easily achievable on any Raspberry Pi 4 — albeit requiring some form of passive or, better yet, active cooling to avoid thermal throttling.
The Raspberry Pi 400 is also entirely ill-suited to embedded work: Even if you shuck it from its housing and discard the keyboard and heatsink, it’s considerably larger than any other model of Raspberry Pi going all the way back to the never-publicly-released Alpha boards.
Neither of these are negative points. The Raspberry Pi 400 isn’t designed to replace the Raspberry Pi 4 in all use cases, but to make the core technology better suited for particular use cases: Corporate desktops, education, and perhaps even the bedroom programmer — a new generation of hackers typing away on an all-in-one keyboard-computer and inventing the future, just as the generation before them hunched over Commodore 64s, Sinclair ZX Spectrums, Atari 400s and other eight-bit marvels.
The Raspberry Pi 400 is available to order today, priced at $70 system-only and $100 in a new desktop kit bundle that includes pre-loaded Raspberry Pi OS microSD card, mouse, power supply, and Beginner’s Guide manual. More information is available on the Raspberry Pi website.

Xen Hypervisor Gets Ported to the Raspberry Pi, Shakes Out Bugs in the Linux Kernel
https://www.hackster.io/news/xen-hypervisor-gets-ported-to-the-raspberry-pi-shakes-out-bugs-in-the-linux-kernel-b9595fe721d4
An “easy” porting task turned into a bug-hunt in the Linux kernel, but Xen is now officially available on the Raspberry Pi 4 family.
The Xen Project, maintainer of the popular hypervisor of the same name, has announced it has now ported its tool to the Raspberry Pi 4 single-board computer — complete with a tutorial for anyone looking to get started.
“We have always been eager to get the Xen hypervisor running on [the Raspberry Pi], but technical differences between RPi and other Arm platforms made it impractical for the longest time,” Xen’s Stefano Stabellini and Roman Shaposhnik explain in a joint announcement. “Specifically, a non-standard interrupt controller without virtualization support. Then the Raspberry Pi 4 came along, together with a regular GIC-400 interrupt controller that Xen supports out of the box.”
