If you want to add a new feature to QEMU you should always
work on git master; we don't accept patches against anything else.

Instead of flushing pending coalesced MMIO requests on every vmexit,
this provides a mechanism to selectively flush when memory regions

In preparation of stopping to flush coalesced MMIO unconditionally on

This patch adds a "use64" property which will make the ivshmem driver
register a 64bit memory bar when set, so you have something to play with
when testing 64bit pci bits. It also allows to have quite big shared

At some point in the past, the OPEN event was changed to be issued from a

Hello,
I have been working on the emulation of the IP-Octal 232 IndustryPack
module, a device that implements eight RS-232 serial ports.
IndustryPack modules are small boards that are attached to a carrier
board, so in order to have a complete and working system I also wrote
an emulation of the T
The TPCI200 is a PCI board that supports up to 4 IndustryPack modules.
A new bus type called 'IndustryPack' has been created so any
compatible module can be attached to this board.

RS-232 serial ports, each one of which can be redirected to a
character device in the host.

I am emulating arm on x86. i want to track the virt and physical
address of last memory operation. so i put 2 fields in the CPUState
and make tcg_global_mem_new_i32 on them Therefore, before every
translation i generate code to save the virtual address as follow:
static inline void gen_st32(TCGv v
The lan9118 emulation tries to compute the multicast index by calling
directly the crc32() function from zlib, but fails to get the correct
result.
Use the common compute_mcast_idx() function instead, which gives the
correct result. This fixes IPv6 support.

Hi,
On behalf of the QEMU Team, I'd like to announce the availability of the
first release candidate for the QEMU 1.2 release. This release is meant
for testing purposes and should not be used in a production environment.
http://wiki.qemu.org/download/qemu-1.2.0-rc1.tar.bz2
You can help improve
Ping! This didn't get into rc1.
thanks

Windows users need to know that they have to use the Baum driver to make
the qemu braille device work.

to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v3.6 kernel[0] (Not a kernel in the daily directory) and install both
