I have two image A and B, and A is the backing file of B
I write data in address addr in A.
Then create B and set A as backing file of B.
Then I discard the same addr in B.
So the entry of addr in l2 table should be 1( also is

It seems that this "bug" affects only 2D-performance mediated through
GDI in Windows (CPU-, not GPU-driven). There have been reports that GDI
switches a lot between user/kernel space.
Are vmexits triggered when the guest switches from user- to kernel-

Page 2-8 in table 2-4 is where the description of this bit can be found.
It is described as:
Floating-point fraction rounded. The last arithmetic, rounding, or conversion
instruction incremented the fraction. This bit is NOT sticky.

In the softfloat.c file there is a function called float64_add(). What I need
is a way to pack and canonicalize a FloatParts value. There doesn't appear to
be any way. This is what I have tried so far, but the results are not good.
The intermediate_result and the rounded_result should be close
The SLOF boot process is always quite slow ... but we can speed it up
a little bit by specifying "-nodefaults" and by using the "nvramrc"
variable instead of "boot-command" (since "nvramrc" is evaluated earlier
in the SLOF boot process than "boot-command").

The global cpu_single_env variable has been removed more than 5 years

Now that cpu->interrupt_request is accessed with atomics,
we can drop the BQL around cpu_reset_interrupt, which is a

cpu->do_interrupt can now be called with BQL held (from
cpu->cpu_exec_interrupt) or without (from cpu_handle_exception).
Only a few targets rely on global device state in cc->do_interrupt;
add checks to those targets to acquire the BQL if not already held.

Most interrupt requests do not need to take the BQL, and in fact
most architectures do not need it at all. Push the BQL acquisition

Hi all
Here is a minimal working version of supporting multiple pci domains.
The next a few paragraphs will illustrate the purpose and use example.
Current issue and limitations will be in last 2 paragraphs, followed
by the changelog of each verison.
Currently only q35 host bridge is allocated
The inner host bridge created by pxb-pcie is TYPE_PXB_PCI_HOST by default,

pxb-pcie resides in pci domain 0 by default and users can not specify the

to pxb-pcie device.
The first property allows user to choose a non-zero pci domain so that

Hi all.
1. bdrv_dirty_iter_next_area don't use hbitmap_next_zero and uses
inefficient loop instead. Let's improve it.
2. bdrv_dirty_iter_next_area don't handle unaligned offset and
max_offset correctly. I'm not sure that it is a real bug. But if it is,
we need these series in 3.0.

The function alters bdrv_dirty_iter_next_area(), which is wrong and
