How to add a new virtual hardware like interrupt unit in QEMU?
How interrupts are handled in QEMU?
I am working on project in which we have add support of a board in QEMU. We
have to add some virtual devices in QEMU. The question which I want to ask
that what should I do to add virtual device. And after adding that device
in \hw in which file I have to make changes so that program access that

Plz someone guide me that how I can add new virtual hardware in QEMU? I
tried t get help from already made hardware but it gives me no
idea...Plz someone guide me and tell me detailed process.
I am watching i8259.c in \hw folder in QEMU. here is something like this
static const VMStateDescription vmstate_pic = {
.name = "i8259",
.version_id = 1,
.minimum_version_id = 1,
.minimum_version_id_old = 1,
.fields = (VMStateField[]) {
VMSTATE_UINT8(last_irr, PicStat
I am looking into a file which is i8259.c which is basically an interrupt
controller. here in end is a function which is
static int pic_initfn(ISADevice *dev)
{
PicState *s = DO_UPCAST(PicState, dev, dev);
memory_region_init_io(&s->base_io, &pic_base_ioport_ops, s, "pic", 2);
memory_r
qdev_init_gpio_out
qdev_init_gpio_in
qdev_set_legacy_instance_id
these functions are from QEMUThese are used in different devices. Can
any body plz tell me what does these do?
Can any one tell me what is qemu_irq and where it is defined in QEMU?
I am doing a task in which I have to enter some data which is in a
directory in qcow/qcow2 file. The thing I want to ask is that how can I do
this if I have boot looder or guest system in a directory rather than in
iso file. I try to make a qcow image and mount it on my file system.
Process for mo
I am running a VM and giving it a qcow file as its root file system.
But it is giving me following error.
ide_generic: please use "probe_mask=0x3f" module parameter for probing
all legacy ISA IDE ports
Can any one tell me what is the kernel configuration to solve this error.
