Hi,
Ok, your used method as the same as ivshmem,
so actually your problem is “how to write driver for ivshmem in windows guests
?”
but IMHO no one has realized this.

Hi,
I noticed that the qemu-2.1 release change log says
" PCIe: Basic hot-plug/hot-unplug support for Q35 machine."
And then I made a testing for the hotplugging function of Q35.
But I'm failed, and I got the dmesg log in guest os as below:
[ 159.035250] Pciehp :05:00.0:pcie24: Button presse

Hi,
Vhost devices need to do VHOST_SET_MEM_TABLE ioctl in vhost_dev_start()
to tell vhost kernel modules GPA to HVA memory mappings, which consume is
expensively.
The reason is same as KVM_SET_GSI_ROUTING ioctl. That is, in ioctl processing,
kmod and vhost calls synchronize_rcu() to wait for gr
Hi, Gerd
The issue consequentially occur, I have tested various qemu versions,
including the current qemu.git.
Any ideas? Thanks.

Hi,
For recent Linux guests, the usb tablet will be suspended when it is idle.
When Qemu detect the usb tablet event, will call uhci_wakeup(), which
according the value of port->ctrl to decide to call uhci_resume() or not.
UHCI_PORT_RD bit is set to 1 for UHCI is resuming, and qemu will not call

+pci_conf[0xc1] |= 0x20; /* Enable USB PIRQ */
+
pci_config_set_interrupt_pin(pci_conf, u->info.irq_pin + 1);
if (s->masterbus) {

Hi,
I know qemu has a test framework, and I get some information
from http://wiki.qemu.org/Features/QTest
Recently I want to use qtest for some modules, but I have no idea
how to run those tests. Such as tests/ e1000-test
Any guidance? Or how to? Thanks in advance!
Best regards,
