We have now got OpenRISC PCI support upstream for Linux 5.20/6.0. git.kernel.org/pub/scm/linux/…

Wow, I just found Embecosm maintains an OpenRISC toolchain download page, that's nice. embecosm.com/resources/tool…

Here is a start of a series on how we went about porting GLIBC to support the OpenRISC FPU. stffrdhrn.github.io/hardware/embed…

In the Linux kernel crypto libraries there are several machine generated constant time math algorithms. I find these fascinating. Talk about walls of code. git.kernel.org/pub/scm/linux/…

Someone ask me for some docker images to make it easy to setup the OpenRISC toolchain and simulator environment. Here they are; I have both or1ksim (or1k-sim-env) and fusesoc (or1k-verilog-env) environments. I hope its useful. github.com/stffrdhrn/or1k…

I finally finished the second installment in my series on the OpenRISC FPU port. Here we discuss updating hardware and simulators. stffrdhrn.github.io/hardware/embed…

The OoenRISC glibc hardware floating point support is getting some love again. I finally have a few brain cycles to spend on this and finished the kernel docs in a blog post. stffrdhrn.github.io/hardware/embed…
