To all experts in video cards reading this:

Do you know, how to initialize a NVidia card in the RISC-V system (such as Unmatched or Polarfire) to the basic VGA mode 3 (text mode, 80x25)? :)

I really wanted to get the Real Console for QSOE, but so far all my efforts to run video BIOS (via U-Boot's bios_emulator) are not successful...

Depending how recent the card is, you might need to implement UEFI & GOP instead. Might be better approach to read any open source driver code on Linux or BSD to find out how to get basic framebuffer
