(1) Looking at BIOS, don't see anything mentioning "MMIO". Could be called something else, I don't know ... looking for the BIOS docs.
Found a reference in a submenu item ... Under BIOS' 'Advanced -> Memory Configuration', there's a "Max TOLUD" entry. Its description states: "Maximum valued of TOLUD. Dynamic assignment would adjust TOLUD automatically based on largest MMIO length of graphic controller." Values are: Dynamic 1.0GB ... (0.25 GB increments) ... 3.25GB It's set to 'Dynamic' by default. Naively changing it to the 3.25GB Max 'just to see' turns out to be a mistake ... renders the system unbootable. ( Reset the BIOS ... ) Unclear if that entry/value is relevant. There's no other MMIO mention in any SUBmenu. -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org
