      qdev: register all types natively through QEMU Object Model · 39bffca2
      由 Anthony Liguori 提交于 
      This was done in a mostly automated fashion.  I did it in three steps and then
rebased it into a single step which avoids repeatedly touching every file in
the tree.

The first step was a sed-based addition of the parent type to the subclass
registration functions.

The second step was another sed-based removal of subclass registration functions
while also adding virtual functions from the base class into a class_init
function as appropriate.

Finally, a python script was used to convert the DeviceInfo structures and
qdev_register_subclass functions to TypeInfo structures, class_init functions,
and type_register_static calls.

We are almost fully converted to QOM after this commit.

      pc: Fix floppy drives with if=none · 34d4260e
      由 Kevin Wolf 提交于 
      Commit 63ffb564 broke floppy devices specified on the command line like
-drive file=...,if=none,id=floppy -global isa-fdc.driveA=floppy because it
relies on drive_get() which works only with -fda/-drive if=floppy.

This patch resembles what we're already doing for IDE, i.e. remember the floppy
device that was created and use that to extract the BlockDriverStates where
needed.

      fdc: Fix floppy port I/O · a18e67f5
      由 Kevin Wolf 提交于 
      The floppy device was broken by commit 212ec7ba (fdc: Convert to
isa_register_portio_list). While the old interface provided the port number
relative to the floppy drive's io_base, the new one provides the real port
number, so we need to apply a bitmask now to get the register number.

      fdc: Make media change detection more robust · 18d90055
      由 Markus Armbruster 提交于 
      fdctrl_change_cb() gets called on a virtual media change via monitor.
It would be nice if host device block drivers called it on physical
media change, but they don't.

bdrv_media_changed() lets you poll for media change, but it returns
"don't know" except with block driver "host_floppy".

FDrive member media_changed gets set on device initialization and by
fdctrl_change_cb(), and cleared by fdctrl_media_changed().  Thus, it's
set on first entry to fdctrl_media_changed() since device
initialization or virtual media change.

fdctrl_media_changed() ignores media_changed unless
bdrv_media_changed() returns "don't know".  If we change media via
monitor (setting media_changed), and the new media's block driver
returns 0, we lose.  Fortunately, "host_floppy" always returns 1 on
first call.  Brittle.  Clean it up not to rely on it.

      change all other clock references to use nanosecond resolution accessors · 74475455
      由 Paolo Bonzini 提交于 
      This was done with:

    sed -i 's/qemu_get_clock\>/qemu_get_clock_ns/' \
        $(git grep -l 'qemu_get_clock\>' )
    sed -i 's/qemu_new_timer\>/qemu_new_timer_ns/' \
        $(git grep -l 'qemu_new_timer\>' )

after checking that get_clock and new_timer never occur twice
on the same line.  There were no missed occurrences; however, even
if there had been, they would have been caught by the compiler.

There was exactly one false positive in qemu_run_timers:

     -    current_time = qemu_get_clock (clock);
     +    current_time = qemu_get_clock_ns (clock);

which is of course not in this patch.

      Add endianness as io mem parameter · 2507c12a
      由 Alexander Graf 提交于 
      As stated before, devices can be little, big or native endian. The
target endianness is not of their concern, so we need to push things
down a level.

This patch adds a parameter to cpu_register_io_memory that allows a
device to choose its endianness. For now, all devices simply choose
native endian, because that's the same behavior as before.

      fdc: Reject unimplemented error actions · b47b3525
      由 Markus Armbruster 提交于 
      drive_init() doesn't permit them for if=floppy, but that's worthless:
we get them via if=none and -global.

This can make device initialization fail.  Since all callers of
fdctrl_init_isa() ignore its value, change it to die instead of
returning failure.  Without this, some callers would ignore the
failure, and others would crash.

Wart: unlike drive_init(), we don't reject the default action when
it's explicitly specified.  That's because we can't distinguish "no
rerror option" from "rerror=report", or "no werror" from
"rerror=enospc".  Left for another day.

      block: Fix virtual media change for if=none · 7d0d6950
      由 Markus Armbruster 提交于 
      BlockDriverState member removable controls whether virtual media
change (monitor commands change, eject) is allowed.  It is set when
the "type hint" is BDRV_TYPE_CDROM or BDRV_TYPE_FLOPPY.

The type hint is only set by drive_init().  It sets BDRV_TYPE_FLOPPY
for if=floppy.  It sets BDRV_TYPE_CDROM for media=cdrom and if=ide,
scsi, xen, or none.

if=ide and if=scsi work, because the type hint makes it a CD-ROM.
if=xen likewise, I think.

For the same reason, if=none works when it's used by ide-drive or
scsi-disk.  For other guest devices, there are problems:

* fdc: you can't change virtual media

    $ qemu [...] -drive if=none,id=foo,... -global isa-fdc.driveA=foo
    QEMU 0.12.50 monitor - type 'help' for more information
    (qemu) eject foo
    Device 'foo' is not removable

  unless you add media=cdrom, but that makes it readonly.

* virtio: if you add media=cdrom, you can change virtual media.  If
  you eject, the guest gets I/O errors.  If you change, the guest sees
  the drive's contents suddenly change.

* scsi-generic: if you add media=cdrom, you can change virtual media.
  I didn't test what that does to the guest or the physical device,
  but it can't be pretty.
