QSOE: QNX-inspired OS with dual-kernel architecture

Re:QSOE: QNX-inspired OS with dual-kernel architecture by ymz5 on Monday June 22, 2026 @07:27PM (#48637923)

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

Exactly. After days of unsuccessful VideoBIOS bring-up (via U-Boot's emulator), I gave up, and implemented exactly what you suggested: graphics mode, using of course parts of nouveau. Claude Code is smart in extracting information.

And it worked!! Now I have the picture on the monitor when U-Boot starts. The only one drawback: it takes 30..40 seconds between the moment of machine-power-on and the picture on the screen.
