RISC-V UEFI Linux Support Under Review

Following Linux's UEFI code getting cleaned up earlier this year in preparation for RISC-V support being added and then some early RISC-V UEFI patches, a more comprehensive set of patches for enabling UEFI support on RISC-V under Linux have been sent out.

Linux Kernel Continues Prepping For RISC-V's Updated Supervisor Binary Interface

RISC-V's Supervisor Binary Interface "SBI" is the interface between the platform-specific firmware and the running operating system or hypervisor for interacting with the supervisor execution environment in the higher privileged mode. The Linux kernel has been working to support a newer version of the SBI that is more extensible moving forward.

NEOX V Announced By Think Silicon As First RISC-V 3D GPU

While there has been the Libre RISC-V community-driven effort to create a RISC-V graphics processor that basically amounts to a RISC-V core with vector extensions/improvements and running a Vulkan software implementation (though they are now reportedly eyeing POWER instead of RISC-V), Think Silicon has announced the first actual RISC-V ISA based 3D graphics processor.

Libre RISC-V Open-Source Effort Now Looking At POWER Instead Of RISC-V

Well, here is a surprise... The Libre RISC-V project that is trying to build an "open-source GPU" more along the lines as a Vulkan accelerator is looking at other options besides RISC-V. While RISC-V is royalty-free and open-source in nature, Luke Kenneth Casson Leighton is not content with the RISC-V Foundation and is evaluating the likes of POWER and MIPS.

Longtime X11/Linux Developer Joins SiFive To Work On RISC-V Processors

Keith Packard has joined RISC-V company SiFive. Yes, the same Keith Packard that is the longest still active (though somewhat more dormant these days) X Window System developer who for many years had led much of the X11/X.Org efforts and worked for nearly a decade at Intel on their open-source Linux graphics driver stack before working for HP Labs and also a side-gig for Valve improving the Linux stack for VR.

Libre RISC-V Snags $50k EUR Grant To Work On Its RISC-V 3D GPU Chip

The very ambitious project working on an open-source RISC-V architecture to serve as a Vulkan accelerator for 3D graphics secured a minor victory last week with receiving $50k EUR from the European Commission's Next Generation Internet initiative. They will be using these funds to allow for full-time engineering work and bounty-style tasks to work on this "100% libre RISC-V + 3D GPU chip for mobile devices."

The State Of Debian & Fedora On The RISC-V Architecture

RISC-V remains of a lot of interest to open-source/Linux users for being a royalty-free and completely open CPU architecture. In part due to the lack of affordable RISC-V hardware limiting developers from working more on this architecture, the state of RISC-V support by Linux distributions varies but at least has improved a lot in recent years.

SiFive Unleashes New 7-Series RISC-V Cores With Better Performance

SiFive this week announced their 7-Series RISC-V cores with the 32-bit E7, 64-bit S7, and 64-bit U7 series. These new RISC-V parts aren't yet capable of running up against the fastest ARM Cortex CPU cores available today, but they are much more powerful than the previous-gen SiFive cores.

Linux Kernel Developers Begin Figuring Out Vendor-Specific RISC-V Code

With the increasingly popular RISC-V open-source processor instruction set architecture (ISA), there is the possibility for vendor-specific instruction set extensions. At this point the kernel has no infrastructure in place for its RISC-V port to allow for such bits, but that is being worked on as part of bringing up AndeStar RISC-V CPUs under the Linux kernel.
