[Qemu-devel] [PATCH v4 09/38] hw/block/fdc: Implement tray status |
Date: |
Mon, 20 Jul 2015 19:45:36 +0200 |
The tray of an FDD is open iff there is no medium inserted (there are
only two states for an FDD: "medium inserted" or "no medium inserted").
This results in the tray being reported as open if qemu has been started
with the default floppy drive, which breaks some tests. Fix them.
