Raptor Announces Kestrel Open-Source, Open HDL/Firmware Soft BMC
Raptor Engineering known for their work on open-source POWER9 systems has announced Kestrel, an open-source baseboard management controller (BMC) design that is open down to the HDL design and firmware.
Raptor describes Kestrel as "the world's first open HDL / open firmware soft BMC, built on POWER and capable of IPLing existing OpenPOWER systems!" This isn't a physical BMC chip but a "soft" BMC that is currently designed and tested on Lattice ECP-5 FPGAs. It can currently handle an initial program load (IPL) for a POWER9 host like the Blackbird and Talos II systems of Raptor Computing Systems after deactivating the existing ASpeed hardware BMC found on those systems.

Intel oneAPI Level Zero 1.1 Headers/Loader Released
The oneAPI Level Zero repository consisting of the Level Zero API headers, Level Zero loader, and validation layer have reached version 1.1.
Following last year's big oneAPI 1.0 "Gold" status, Intel's open-source oneAPI effort continues moving along with the Level Zero focus as their low-level, direct-to-metal interface for offload accelerators like GPUs and other "XPU" devices.

[Older] A short journey to x86 long mode in coreboot on recent Intel platforms
While it was difficult to add initial x86_64 support in coreboot, as described in my last blog article how-to-not-add-x86_64-support-to-coreboot it was way easier on real hardware. During the OSFC we did a small hackathon at 9elements and got x86_64 working in coreboot on recent Intel platforms.
If you want to test new code that deals with low level stuff like enabling x86_64 mode in assembly, it's always good to test it on qemu using KVM. It runs the code in ring 0 instead of emulating every single instruction and thus is very close to bare metal machines.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
