[Qemu-devel] [RFC 00/10] fix 2.88mb floppy diskette support

[John Snow <jsnow@redhat.com>]

Yep, it's been broken for 10 years too.
No, it's not a CVE.

The problem is that QEMU doesn't have a configuration option
for the type of floppy drive you want. It determines it based
on the diskette you insert at boot.

If you don't insert one, it always chooses a 1.44MB type.

I want to change the default to a 2.88MB type and users to switch
back and forth between 2.88 and 1.44MB diskettes.

Shuffle things around a bit to make this magic happen.

This is just an RFC, for many reasons, mostly the 2.4 timeframe,
my unfamiliarity with the qdev property system, uncertainty over
where/how I added this properties, uncertainty over whether or not
READ_ID is really expected to work without a floppy disk or not
(which impacts if fdc-test is broken or not!) and other sloppy
design issues.

John Snow (10):
  fdc: Make default FDrive type explicit
  fdc: add default drive type option
  fdc: respect default drive type
  fdc: move pick_geometry
  fdc: refactor pick_geometry
  fdc: add physical disk sizes
  fdc: add disk field
  fdc: refactor pick_geometry
  qtest/fdc: Support for 2.88MB drives
  fdc: change default drive to 288
