Transparent Hugepages Are Coming To RISC-V On Linux

The Linux kernel's RISC-V support continues picking up remaining features not yet wired up beyond the base architecture support. The latest is transparent hugepages (THP) to be supported for RISC-V with Linux 5.14.

Intel Reportedly Interested In Acquiring RISC-V Firm SiFive

Back in March during the announcement of Intel Foundry Services it was mentioned that SiFive and Intel were working together to allow RISC-V chips to be fabbed within Intel's facilities. Additionally, Intel Capital previously invested in SiFive during prior funding rounds. Now it turns out Intel is reportedly positioning to potentially acquire SiFive.

A Number Of Exciting RISC-V Improvements For Linux 5.13

From bringing up the PolarFire ICICLE SoC to adding support for KProbes, FORTIFY_SOURCE, and other new kernel features for the RISC-V architecture, the Linux 5.13 kernel changes are exciting for this open-source processor ISA.

SiFive FU740 PCIe Support Queued Ahead Of Linux 5.13

Arguably the most interesting RISC-V board announced to date is SiFive's HiFive Unmatched with the FU740 RISC-V SoC that features four U74-MC cores and one S7 embedded core. The HiFive Unmatched also has 16GB of RAM, USB 3.2 Gen 1, one PCI Express x16 slot (operating at x8 speeds), an NVMe slot, and Gigabit Ethernet. The upstream kernel support for the HiFive Unmatched and the FU740 SoC continues.

Alibaba Reports Their XT910 RISC-V Core To Be Faster Than An Arm Cortex-A73

A few weeks back Alibaba announced the "XT910" as the fastest RISC-V processor featuring 16 cores and clock speeds up to 2.5GHz while being manufactured on a 12nm node. This by far beats most RISC-V hardware currently available and now at this week's Hot Chips conference the Chinese company is reporting that the XT910 is faster than an Arm Cortex-A73.

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."
