Hi Gerd, I was curious to see what the "sercon" stuff would look like in SeaVGABIOS instead of in SeaBIOS. So, I put together a quick prototype. The code is also at:
https://github.com/KevinOConnor/seabios/tree/testing This is just a proof-of-concept thing - I didn't implement any of the useful features you have in your series. Specifically, it doesn't unclutter the serial output, doesn't implement cp437 translations, and doesn't handle multi-byte input. It does does have basic input, output, and split-output handling though. I'm not sure if this is better than a SeaBIOS implementation. I suspect it will be easier to handle vga quirks this way. However, handling exotic serial outputs (eg, mmio and usb based) would be better suited in SeaBIOS. Thoughts? -Kevin Kevin O'Connor (3): sercon: Initial support for VGA emulation over serial port sercon: Add basic keyboard input support sercon: Support "split output" mode Makefile | 2 +- vgasrc/Kconfig | 6 + vgasrc/sercon.c | 356 ++++++++++++++++++++++++++++++++++++++++++++++++++++++ vgasrc/vgabios.c | 15 ++- vgasrc/vgabios.h | 5 + vgasrc/vgaentry.S | 7 ++ vgasrc/vgahw.h | 72 ++++++++++- vgasrc/vgainit.c | 12 +- vgasrc/vgautil.h | 24 ++++ 9 files changed, 482 insertions(+), 17 deletions(-) create mode 100644 vgasrc/sercon.c -- 2.5.5 _______________________________________________ SeaBIOS mailing list SeaBIOS@seabios.org https://www.coreboot.org/mailman/listinfo/seabios
