[HDMI2USB] Port Linux to the lm32 CPU and support HDMI2USB firmware functionality #30

Open mithro opened 8 years ago

mithro commented 8 years ago

Brief explanation

The HDMI2USB gateware currently includes a lm32 soft core. The misoc version has an MMU and should support running a full Linux kernel.

Expected results

Linux booting on the HDMI2USB gateware.

Detailed Explanation

There is a bunch of extra information in the LiteX Linux Support Random Notes Google Doc.

The HDMI2USB-misoc-firmware embeds a LM32 soft-core for controlling and configuring the hardware. See the diagram below;

MiSoC firmware structure

This soft-core should be able to run Linux Kernel, which means we would get access to a lot of good things;

Work on this was started by the MilkyMist / M-Labs people.

There is a port of the lm32 to qemu which will help, see https://github.com/timvideos/HDMI2USB-misoc-firmware/issues/86

Just dropping a note so that people know a good amount of work on this has been done in linux-lm32

Linux isn't possible on lm32, due to bitrot. However we have it booting on or1k. 10/100 Ethernet is also working as of Jan 2018. See above instructions.

Also, I might add that current lm32 Linux port, whatever its bitrot state, isn't using the MMU. It's uCLinux (noMMU). MMU is experimental also.
