RISC-V

on r/RISCV

This new code provides the necessary Linux kernel changes for dealing with RISC-V's "V" Vector Extension, including new prctl() interfaces so user-space can check on the status of Vector extension support. a new sysctl knob "riscv_v_default_allow" to adjust changing the default for allowing Vector extension use by user-space software, the "RISCV_ISA_V" Kconfig option for toggling kernel build support with this ISA extension, and various other changes.

"Although it's not yet in the official architecture list, the riscv64 port is making good progress. We expect to be in a position to ship trixie with riscv64 support (subject to architecture qualification later in the cycle)."

"I’ll walk through my steps of creating an emulator, compiling and linking C for bare metal, CPU design and finally the implementation of my toy RISC-V CPU."

Ubuntu has announced support for The PolarFire SoC FPGA Icicle Kit RISC-V Board. I am not always a huge fan of Ubuntu but if you're looking to get into RISC-V boards they seem to be always on the forefront of support. RISC-V is a great platform to get into as many boards have an open source BIOS and the architecture as a whole is a lot more open than x86.

The board can be found on Mouser among other stores.
