I tested this patch as follows:
I put printf()s into involved functions. Then ran qemu on a terminal
emulator, and resized it.
The guest kernel gets initial size. However, it doesn't update the size.
It seems to need to enable multiport for resize.

The LSI controller was lacking a system reset handler. Simply invoke the
existing soft reset handler in this case. This also allows to drop its
explicit invocation during init.

Hi,everyone!
I just add AHCI Emulation into qemu.
I have tested it on linux kernel,it works well.
run like this:
qemu -hda disk ...
Now only support sata disk.

Hi,
I am interested in adding a Renesas ARM Multicore Cortex A9 Development board
to Qemu.
Are there any FAQs on how to this?
Is anyone else working on adding additional Platforms/Boards to Qemu?

Hi Anthony,
this is the second part of the block patches in my queue that I promised in the

didn't sit on the list for a very long time - but the people that I expected to
comment on it have already done so, either on the
From: Christoph Hellwig h...@lst.de
We're running into various problems because the raw file access, which
is used internally by the various image formats is entangled with the
raw image format, which maps the VM view 1:1 to a file system.
This patch renames the raw file backends to the file
bdrv_open contains quite some code that is only useful for opening images (as
opposed to opening files by a protocol), for example snapshots.
This patch splits the code so that we have bdrv_open_file() for files (uses
protocols), bdrv_open() for images (uses format drivers) and bdrv_open_common()
Move bdrv_open_common so it's defined before its callers and remove the forward
declaration.

This fixes the problem that qemu-img's use of no_zero_init only considered the
no_zero_init flag of the format driver, but not of the underlying protocols.
Between the raw/file split and this fix, converting to host devices is broken.

When trying to do COW, VMDK wrote the data back to the backing file. This
problem was revealed by the patch that made backing files read-only. This patch
does not only fix the problem, but also simplifies the VMDK code a bit.
This fixes the backing file qemu-iotests cases for VMDK.
It's a format driver, so implement bdrv_open instead of bdrv_file_open.

VMDK is doing interesting things when it needs to open a backing file. This
patch changes that part to look more like in other drivers. The nice side
effect is that the file name isn't needed any more in the open function.

This patch combines the lseek+read/write calls to use pread/pwrite

The BlockDriver bdrv_getlength function is called from the I/O code path

While it's true that during regular operation free_clusters failure would be a

qemu-img rebase must always give clusters in the COW file priority over those
in the backing file. As it failed to use number of non-allocated clusters but
assumed the maximum, it was possible that allocated clusters were taken from
the backing file instead, leading to a corrupted output image.

Details in the patches.
One of the most important missing feature in QMP today is its
supported command documentation.
The plan is to make it part of self-description support, however
self-description is a big task we have been postponing for a
long time now and still don't know when it's going to be done.

Previous commit added the QMP/qmp-commands.txt file, which is a
copy of this information.
While it's good to keep it near code, maintaining two copies of
the information is too hard and has little benefit as we don't
expect client writers to consult the code to find this kind of
documentation.
