The ppc64 code generation backend uses an rldicr (Rotate Left Double

a 32 bit quantity to a 64 bit quantity (INDEX_op_ext32u_i64). However
this is wrong - this instruction clears specified low bits of the

I add COW to it to support backing_file option. I store dirty bitmap in an

Commit 23c5e4ca (convert to memory API) broke the VIA Cuda emulation layer
by not registering the IO structs.
This patch registers them properly and thus makes -M g3beige and -M mac99

I find nbd quite useful to test migration, but it is limited:
it can only do synchronous operation, it is not safe because it
does not support flush, and it has no discard either. qemu-nbd
is also limited to 1MB requests, and the nbd block driver does
not take this into account.
Luckily, flush/FU
The flexible array member should remain the last member in the structure
as this assumption is based upon in the code.

Gdb expects all registers windows to be flushed in ram, which is not the case
in Qemu. Therefore the back-trace generation doesn't work. This patch adds a

Hi,
I modify the code like this, and the PCI_INTERRUPT_LINE register is set, and I
can bind
it to uio_pci_generic:

This is a report of strange cfq behaviour which seems to be triggered by
QEMU posix aio threads.
Host environment:
OS: RHEL6.0 KVM/qemu-kvm (with no patch applied)
IO scheduler: cfq (with the default parameters)
On the host, we were running 3 linux guests to see if I/O from these guests
would

The (x << (cl - 1)) quantity is only used if CL != 0. Move the
computation of that quantity nearer its use.
This avoids the creation of undefined TCG operations when the
constant propagation optimization proves that CL == 0, and thus
CL-1 is outside the range [0-wordsize).
