#alt4you Screenshot from the linked repo, text: "Creating the SG2000 Emulator... Doesn’t look so hard?
Yeah I'm begging all RISC-V SoC Makers: Please provide a Software Emulator for your RISC-V SoC! A
Just follow the steps in this article to create your RISC- V Emulator. Some SoC Peripherals might be missing, but a Barebones Emulator is still super helpful for porting, booting and testing any Operating System."

@lupyuen So true. Honestly, I think there should at least be a minimal emulator for every SoC. It helps a lot with operating system development.

@lupyuen maybe I should persuade all SoCs with PCIe to implement PCIe-CPU coherency (because currently Linux in-tree GPU drivers require it)
